Reference, Year, and Country | Objectives | School Sample (SS) Teaching Stage (TS) Participants (P) | Sensory Evaluation and Acceptance Methods Performed | Evaluated Attributes | Results |
---|---|---|---|---|---|
Head et al. (1977) USA [39] | To measure the acceptability of school-served food items by three methods and evaluate the relative usefulness of each | SS: n = 13 TS: Elementary, middle, and high school P: Students (n = 240) | Three methods Form with: 5-point hedonic scale “How you liked it?” (“great” = 5, “good”, “OK”, “not very good”, or “terrible” = 1) 5-point scale “How much you ate?” (“all” = 5, “most”, “about half”; “just tried it”, or “none” = 1) Mean weight = weight of 4 served trays PW = from every 2nd, 3rd, or 4th student who had completed scales. Separated by individual food items from every 25 students (pooled and weighed) Estimate of the amount consumed = mean plate waste − mean amount served (for each item) | Acceptability Hedonic rating scale (HED) Amount consumed rating scale (AMT) Plate waste | The reliability of the HED scale was highly significant, and the AMT scale was significant for all but one item. The interaction of HED and AMT scores was insignificant, implying that liking or not liking had little effect on how students reported how much they had eaten. The analysis showed a more positive relationship between the AMT score and food consumption than the HED score and consumption. A statistical model was constructed for predicting food consumption from ratings; it was possible to obtain an indication of consumption by elementary students from either scale. |
Devan et al. (1988) USA [40] | To assess the influence of vegetable preparation training on the amount of vegetable plate waste; to compare student ratings of cooked vegetables before and after training; and to determine if quality characteristics, as measured by a professional sensory panel, are affected by training in proper vegetable preparation techniques | SS: n = 5 TS: Elementary school P: Students (from 37 to 147) | 5-point hedonic scale (“great”, “good”, “so-so”, “bad”, and “awful”) 3-point hedonic scale (“hot”, “just right”, and “too cool”); (“too much”, “right amount”, and “too little” Visual estimate Portion of broccoli remaining: “full portion” (4) to “none remained” (0) | Sensory quality Flavor and appearance of broccoli Temperature and amount of broccoli Plate waste | The average scores referring to the sensory quality of broccoli for schools A, B, C, D, and E were flavor (2.9; 2.43; 2.57; 2.89, and 2.84), appearance (2,14; 2.26; 2.29; 2.40, and 2.51), temperature (1.49; 1.57; 1.57, 1.68, and 1.83), and portion size (2.42; 2.48; 2.22; 2.05, and 2.24), respectively. |
Stalls (1997) USA [41] | To determine the level of acceptability of three different low-fat brownies compared to the USDA brownie recipe | SS: All schools in the school district (n = not informed) TS: Elementary school P: Students (n = 77) | 9-point hedonic and pictorial face scale “super good” (9), “really good” (8), "good" (7), “just a little good” (6), “maybe good or maybe bad” (5) to “super bad” (1) | Sensory evaluation Consumer preference or acceptance/likability testing (to measure how much 4th-grade students like, prefer, or accept) | The average flavor score for the regular brownie was 7.2. Most students (83.11%, n = 64) rated the brownie between “super good” (9) and “just a little good” (6), while 11.68% (n = 9) judged it as “just a little bad” (4) to “super bad” (1). |
Kim and Kim (1997) South Korea [42] | To contribute to improving the quality of school lunches by analyzing the satisfaction of school lunches provided in schools for children of meals in Seoul, a large city, and Gangneung, a small city | SS: n = 28 TS: Elementary school P: Students (n = 3.590) | 5-point Likert scale (1 = ”very dissatisfied” to 5 = “very satisfied”) % of students who had left leftover food (by grade and food type) (“food is not warm”, “disliked food”, “the food is tasteless”, “have no appetite”, “cooking was not done properly”, or “too much”) | Satisfaction (appearance, taste, temperature, texture, and overall satisfaction) Examination of leftover food (type of food left: rice, soup, kimchi, side dish, and milk) Reasons to leave food | The general satisfaction regarding the type of food was: rice (3.90 and 3.78), soup (3.70 and 3.64), side dishes (3.79 and 3.66), and milk (2.60 and 2.53) for boys and girls, respectively. The mean leftover was higher for soup and lower for rice. The major reasons for leaving leftover were “dislike the food” (27.4%), “too big portion size” (23.6%), “food is not tasty” (19.1%), “low appetite” (17.6%), “food is too overcooked or undercooked” (3.9%), and “food is not hot enough” (3.2%). |
Baxter et al. (2000) Georgia [43] | To estimate the relationship between fourth-grade children’s consumption and preferences for school lunch foods through observation | SS: n = 4 TS: Elementary school P: Students (n = 237) | Eaten amounts observed (coded as none = 0.0, taste = 0.1, some = 0.25, half = 0.5, most = 0.75, all = 1, and >1 serving = 2) Interview (audio-recorded and transcribed) Students were asked what they ate for school lunch (free and non-suggestive prompted recall) and whether they liked foods observed and/or reported eaten “not at aIl”, “a little”, or “a lot” (coded as 0, 1, and 2, respectively) | Children’s observed consumption Preferences for school lunch foods | Results indicated a significant relationship between observed consumption and preferences (p < 0.001); as preferences increased, consumption also increased. Consumption (least squares means with standard error in parentheses) was 0.11 (0.04) servings for foods liked “not at all”, 0.54 (0.03) liked “a little”, and 0.92 (0.02) liked “a lot”. All other main effects and interactions with preferences failed to reach statistical significance (all p’s > 0.14). Thus, the children eat virtually all of what they like “a lot”, about half of what they like “a little”, and almost none of what they like “not at all” during school lunch. |
Brandão (2000) Brazil [44] | To evaluate the acceptance, preference, percentage of adherence, opinions, and expectations of students from 1st to 4th grades, regarding the menus of the school lunch program of municipal schools in the city of Campinas between 1997 and 1999 | SS: n = 10 (1st step) n = 4 (2nd step) TS: Elementary school P: Students (n = 5.407: 1st step) (n = 384: 2nd step) | Average acceptance % = 100 − [(T0 × 0) = (T25 × 25) = (T50 × 50) = (T75 × 75) = (T100 × 100)]/T0 + T25 + T50 + T75 + T100 Weight of prepared food = W × H × Hp/100 (P = specific weight of the prepared food, A = area (diameter) of the cooking pot, Hp = height reached by the food in the pot) % of average acceptance = prepared − clean leftovers − leftovers × 100/prepared − clean leftovers, that is, the total weight of the lunch consumed × 100/total weight of the distributed lunch % of adherence = nº of students who joined the SMP/nº of students present (on the day and period) × 100% % of average repetition = number of students who repeat the SMP menu/number of students who adhered × 100% Adherence (Questionnaire I) Questions (n = 6) or Non-adhesion (Questionnaire II) Questions (n = 4) Open-ended, closed-ended questions Facial structured hedonic scale (5-points) | Acceptance and preference (1st step) Visual estimate (VE) of leftovers on each plate Amount of food left on the plate (0%, 25%, 50%, 75%, or 100%) Measures of aggregate leftovers (MAL) Program adherence percentage Menu repetition percentage Adherence and non-adherence (2nd step) The type of snack consumed and the opinion Acceptance | The average acceptance of all menus, obtained by the VE and MAL methodologies, indicated that the levels were highly satisfactory, ranging from 88 to 94% of acceptance. As for the % of adherence, some schools had very low levels, and it varied between 22.41 and 71.09%. The average percentage of repetition was 25%, and only two schools did not allow repetition. In the second stage, students who joined and did not join the program listed which types of food they would choose to include in school lunches and presented very similar food choices. Some foods were already on the menus, such as fruits, rice with meat, and soups, and some mentioned nutritious foods, such as leafy and non-leafy vegetables, rice and beans, and sandwiches, notably hot dogs. The menu’s average values of acceptance, both those who adhered and those who did not, were between 3.0 and 4.0, that is, between “neither liked/nor disliked” and “liked” on the scale. |
Sturion (2002) Brazil [45] | To evaluate the performance of the school feeding program in municipalities in different regions of Brazil, with different management characteristics | SS: n = 20 TS: Elementary, middle P: Students (n = 2.663) | % of acceptance = weight or volume of the preparation consumed/total weight or volume of the preparation × 100 % of repetition = nº of students who repeat the menu/nº of students who joined the program × 100 IAE = total number of students effectively served/total number of students enrolled × 100 Questions (n = 5) “Do you usually eat the lunch offered at school?” (“yes” or “no”); “How many days a week?” (1 day/wk, 2 or 3 days/wk, 4 or more days/wk); “Name up to 5 foods that you most and least like to eat in school lunches” (n = 2); “If you don’t eat the lunch offered at school, write the reason” | Acceptance (measures of aggregate leftovers) Repetition percentage Adherence effective attendance index (IAE) High (>70%), medium (50 to 70%), low (30 to 50%), and very low (<30%). Custom and weekly frequency of consumption | The average rate of acceptance of the menus, obtained from the method of “Measures of Aggregated Leftovers”, is around 85%, broken down by school unit, the highest index being 97.0% and the lowest 72.9%, with significant differences between schools. The repetition rate is linked to the availability of leftover food. Thus, it cannot be adopted as an indicator of acceptance of the meal. The average rate of total adherence based on the effective attendance index (IAE) was low (45%), the highest being 88.3% and the lowest being 18.6%. As for the habit and frequency of snack consumption, only 46% did it daily. The highest is 81.0% by a school, and the lowest is 15.2%. |
Pagliarini et al. (2003) Italy [46] | To set up an evaluation card and a procedure to test the grading of meals supplied to school refectories by the Municipality of Milan | SS: n = 2 TS: Elementary school P: Students (n = 88) | 7-point hedonic facial scale Super good (7), really good (6), good (5), maybe good or maybe bad (4), bad (3), really bad (2), and bad (1) | Acceptability “Appreciated” ≥4 | As for the averages of acceptability observed from schools’ R and L: first course (4.41; 5.02), second course (4.62; 5.15), vegetables (4.19; 4, 87), and fruits (4.93; 5.46), respectively. For R and L schools, the most appreciated first dishes were: pasta with bolognese sauce for both (5.39; 6.00). Second course: roast chicken for both (6.23; 6.50). Vegetables: baked potato for both (5.97; 6.08). Fruits: orange (5.58 for R). The least liked first course: buttered pasta (3.34) and vegetable puree (3.87). Second course: potato omelet for both (2.92; 3.72). Vegetables: carrots (2.83) and red salad (2.78). Fruits: pear (4.19), respectively. For school L, no significant differences were found in fruit preferences. There were no significant differences in preparation between the two grades and schools. |
Hong and Chang (2003) South Korea [47] | To identify the attributes of food and service quality, to examine the levels of satisfaction and plate wastes leftover in school meals, and to determine the relationship between student satisfaction and plate wastes | SS: n = 11 TS: Elementary school P: Students (n = 999) | 5-point Likert scale (1 = ”not at all”, 2 = ”no”, 3 = ”normal”, 4 = ”yes”, or 5 = “very much”) 6-point Likert scale (1 = ”never eating”, 2 = ”eating little”, 3 = ”eating a quarter”, 4 = ”eating a half”, 5 = “eating three quarters”, or 6 = ”eating all”) (“too much”, “having no appetite”, “disliking foods”, “bad taste”, “undercooking/overcooking”, or “too often provided foods”) 5-point Likert scale (1 = ”not at all”, 2 = ”no”, 3 = ”normal”, 4 = ”yes”, or 5 = “very much”) | Satisfaction Food (preference, variety of menu, taste, appearance, temperature, usage of seasonal food, nutrition balance, food safety, serving size) Food intakes (for cooked rice, soups, kimchi, meats, fish, vegetables, and dessert) Reasons for leaving foods Satisfaction scores by eating habits (“leaving foods” or “eating all foods”) | The satisfaction score with the foodservice quality for the food-related factors was “average” (mean 3.20). The highest satisfaction was for the “nutritional balance” attribute (3.85) and the lowest was for “appearance” (2.87). The intake rates of soup, kimchi, fish, and vegetables were lower than those of other foods. Regarding the relationship between satisfaction and food leftovers, it was observed that the group “eating all foods” had significantly higher satisfaction scores with the meal than the group “leaving foods”. Rice was the type of food most left by the students, and the main reasons were “too much” and “having no appetite”. |
Flávio et al. (2004) Brazil [48] | To determine the chemical composition and acceptance of the lunch offered to the elementary school students of public school in Lavras, MG, and to verify if they meet the objectives of the School Feeding National Program | SS: n = 1 TS: Elementary, middle P: Students (n = 598) | Questionnaire Questions: objective (n = 4) (yes or no; yes or no; (does not consume, 1x/wk to 5x/wk) and Subjective (n = 2) (more or less preferred menus and the menus that students repeated the most or not) | Preference and acceptance | Most of the students (72%) had the habit of consuming the lunch offered by the school. Regarding the weekly frequency of consumption, 25% consumed daily, and 16% did not. The main reason was not feeling hungry when the lunch was distributed. A total of 61% of students had the habit of repeating their school lunch. As for students’ preferences, rice seasoned with ground beef had the highest percentage of choice (90%), and corn flour soup with eggs and cabbage had the lowest (27%). |
Martins et al. (2004) Brazil [49] | To evaluate the acceptance of school meals in the elementary public schools of Piracicaba/SP that benefited from the National School Meal Program | SS: n = 12 TS: Elementary, middle P: Students (n = 480) | Acceptability = average acceptance, rejection, and adhesion rates for the preparations served % of acceptance = total weight of food distributed/total weight produced to serve the clientele Total weight produced = average weight of the portion served × nº of portions served + leftovers (food not distributed) % of wasted meal = weight of food distributed/weight of food discarded (served and not consumed) Adherence rate = % of students who joined the meal/total number of enrolled students present on the assessment day Questionnaire Questions (n = 4) (“Do you usually eat the lunch offered at school? If so: “which dishes do you like the most?” If no: “why don’t you eat it?” “which dishes do you like least?”) | Acceptability Acceptance index aggregate leftovers method “High” = 90% Rejection index waste = values greater than 10% Adherence index “High” (>70%), “medium” (50 to 70%), “low” (30 to 50%), and “very low” (<30%) Reasons for adhering to school meals and more and less acceptable preparations | The results showed reasonable acceptability. Despite the high acceptance of some meals (above 90%), adherence to the preparations served at students’ entrance and recess time is “very low” (lower than 30%) and “low” (40 to 50% approximately), respectively. The rejection numbers found were close to expectations. The main reason for not eating school lunch was not liking the food (48%). Despite this, 67.7% of those who consume school lunches said they liked the food, it being the main reason for consuming them. The dishes they liked the most were pasta with meat (22%), chicken risotto (20%), and rice and beans (19%), while the ones they liked least were soups (47%). |

Asked daily: “liked” or “disliked” each preparation separately | Acceptance Real intake of food | A total of 148 breakfast trays and 460 lunch trays were delivered, and the actual consumption came from measurements performed on 429 and 1491 trays, respectively. As for the proportion of positive responses (I liked) about lunch, for salad, only in 44.1% of the trays the children responded that they liked it. The acceptance of main dishes was very good (86.2%), with legumes being the most accepted (over 90%). There were 67.1% acceptance for desserts, the highest for natural fruits and jellies, and the lowest for dairy desserts. As far as breakfast is concerned, dairy products are mostly well-accepted. The “liked” aspect presents a good correlation with the acceptability aspect; the least consumed preparations correspond to those with the highest proportion of “did not like”. |

Why?”) Analysis of the questionnaire and interview carried out = collective statements (written in the 1st person singular) made with extracts from different individual statements | Acceptance Employees’ perception (the questions were recorded and transcribed into a database) Qualitative methodology of the collective subject discourse (CSD) | Adolescents prefer “competitive” foods sold in establishments close to the school and/or brought from home and do not like the meals offered by the program. They adhere to it, as it is the only alternative they have at school. In the view of employees, 63.4% believe that teenagers like school lunches. However, they considered that some of the foods are not part of the adolescents’ eating habits and that some foods do not attract them, which is why they waste them. A total of 54.6% of employees agree with changes in the menu and suggest changes related to food composition and its flavor and texture characteristics. |

Effective acceptance to the program was 28.8% (“excellent and “very good”), with no significant difference between the levels of education. Among those who considered it “regular” or “poor”, one of the main reasons was the “monotony of the menu”, by repetition of “noodles” or “soup”. Effective adherence was 45.1% (≥4x/week) and was significantly higher among EJA students (72.9%) when compared to EJA students. High school (44.2%) and elementary school (41.2%). In total, 73.5% of the students suggested improvements in school meals, the most frequent being “include fruits in the menu” (27.2%) and “change the menu” (24.5%). |

In Section II of the Participation Survey, the top reason for eating school lunch was “I am hungry” (77%, n = 222), and the least cited reason was “I get a homemade meal” (2%, n = 6). In Section II of the Non-Participation Survey, more than 60% said they would be more likely to eat school lunches with better-tasting food, quality, and shorter lines. |
Silva et al. (2016) Brazil [84] | To evaluate food waste through the acceptance and the school feeding membership served in three public schools of elementary school II of the municipal school system, located in the city of Itapetinga, BA | SS: n = 3 TS: Middle school P: Students (n = 720) | 5-point hedonic scale (“disliked a lot” to “liked a lot”) Acceptance rate (%) = 100 − % of rejection 3-point hedonic scale (“slightly seasoned/very cold/a little”, “ideal”, “highly seasoned/very lot/a lot”) Questionnaire Questions (n = 4) (“yes”, “no”, “no answer”) | Acceptance (for each preparation served) Acceptability rate (seasoning, temperature, and quantity served) Adherence and degree of satisfaction (if you eat, like it, usually repeat it and eat before going to school) | The school lunch acceptability index was below 85% (a limit established by Brazilian legislation). That is, it was not well accepted by students based on their preferences. Most responded that the temperature (56.91%), seasoning (54.5%), and quantity (58.25%) of the meals served were ideal. Of the three schools, two showed good adherence rates (over 80%), and one had a low rate (57%). Most (68%) liked the preparations served, and the main reasons for not consuming were: preferring to buy food in the canteen, not liking the meals served, the meal having little seasoning, or not feeling hungry in the morning. Regarding satisfaction, 23.3% have the habit of repeating their lunch, and 76.3% eat before going to school. |
Balestrin et al. (2016) Brazil [6] | Evaluate the acceptance of food in an elementary school | SS: n = 1 TS: Elementary, Middle P: Students (n = 138) | 5-point hedonic facial scale (1st to 5th grade) or 5-point hedonic verbal scale (6th to 8th grade) (“hated” to “loved’) | Acceptability index “Accepted” = ≥85% (adding “liked” and “loved”) | A total of 78.5% of students from 1st to 5th year marked the options “I liked” and “I loved”. A similar result was found among students from the 6th to the 8th grade (72.6%). Thus, they were not accepted, as the percentages of acceptability were not higher than 85%, as the National School Feeding Program recommended. |
Silva and Barros (2016) Brazil [85] | To evaluate the acceptability of school meals at the Municipal School of Child Education and Primary Cecilia Estolano Meireles | SS: n = 1 TS: Teaching youth and adults (EJA) P: Students (n = 20) | Semi-structured questionnaire Questions (n = 9) (2 to 9 answer options) Tips to improve school lunch | Acceptability The habit of consuming, consumption frequency, like the offered meals, foods they do not like, reason leading to eating, temperature, quantity, bring the food home, food provided they like best, tips of students to improve school lunches | 85% of students have the habit of consuming school meals, and most (70%) consume 5 times/week. Only 15% like all meals and 70% do not like some. As for the foods they do not like, the most cited was bread with butter, sweet biscuit/salty, and tea (by 20% of the students each). The main reason to eat was to feel hungry. The temperature was considered good (55%), and the amount was considered sufficient (85%). Everyone (100%) usually brings food from home; the most they like are hot dogs and juices (30% each). The most reported tip to improve school meals was to diversify the menu. |
Maietta and Gorgitano (2016) Italy [86] | To analyze to what extent pupils value the characteristics of the state school food service and identify which variables affect the degree of pupils’ satisfaction with the quality of school meals | SS: n = 33 TS: Elementary school P: Students [87] (n = 2.210) | Questionnaire Questions (n = 2) (“not satisfied” (level 1), “poorly satisfied” (2), “sufficiently” (3), “fully” (4), or I do not know Food characteristics/menu What do you wish for? Which foodstuff do you leave most often? | Satisfaction Level of pleasantness of eating at school Level of school food tastiness Reasons for dissatisfaction Tastier food, a dessert, more meal variety, more fresh fruit and/or vegetables, hotter food, a larger serving Foods that are most often not eaten Pasta, fish, vegetables, bread, fruit, meat | Regarding the taste level of the food, 48% said they were sufficiently or completely satisfied, and 2% could not. The main reason for dissatisfaction was the absence of tasty food. As for the level of pleasure in eating at school, 53% of students are sufficiently or completely satisfied, and 1% could not say. The foods most often not consumed are pasta, fish, and vegetables. When controlling for variables (characteristics of the student, family, school, food service, and catering company), it was observed: (i) the size of the catering company negatively impacts student satisfaction with the food service, and (ii) the estimated average cost of production of the meal is positively associated with student satisfaction. |
Bez (2017) Brazil [87] | To evaluate the school feeding menus regarding the acceptance and compliance of the nutritional parameters established by the PNAE in a municipal school in the city of Francisco Beltrão, PR | SS: n = 1 TS: Elementary school P: Students (n = 150) | Reject percentage = rejected meal weight × 100/distributed meal weight % of acceptance = 100 − % of rejection | Rest ingestion index “Accepted” ≥ 90% | Of the five days of evaluation, in three, there was a percentage of acceptance greater than 90% within the program’s parameters, meaning that the menus offered were accepted. However, on the other days, an index of 89.53% and 78.27% was obtained, being considered not accepted by the students. |
Sanabria et al. (2017) Paraguay [14] | To evaluate the degree of acceptance and percentage of nutritional requirements adequacy of the scholar lunch of children from two public schools from Asunción | SS: n = 2 TS: Elementary, middle P: Students (n = 102) | 5-point hedonic facial scale (“I don’t like it at all” to “I love it”) Percentage of food consumption = final weight/initial weight × 100 | Degree of acceptance Food consumption | The degree of acceptance of school lunch was conditioned by the type of menu offered on the day. As for the facial hedonic scale, about 3 out of 10 children said the food was to their liking. When estimating the percentage of consumption, more than half consumed about 75% or more of the daily meal. However, when the menu included legumes, the acceptance percentage for both indicators was lower. The majority (80%) stated that the amount was sufficient and satisfied them. Already 8 out of 10 said they wanted to add one more meal to the daily menu, and ¼ chose Milanese as their favorite meal. |
Da Silva et al. (2017) Brazil [88] | To assess whether specific food education activities in public schools could improve food knowledge and promote the acceptance of meals planned by the National School Feeding Program | SS: n = 3 TS: Elementary school P: Students (n = 243) | 5-point hedonic facial scale (“hated” to “loved’) and Questionnaire Questions (n = 2) (What did you like the most/least about the preparation?) Distributed meal portion (g) = total weight of the preparations produced − total weight of the leftovers of the preparations/nº of distributed meals Per capita leftover intake (g) = total leftovers left by students/nº of meals consumed Rest Intake index = per capita of rest intake (g)/distributed portion (g) × 100 Questionnaire Questions (n = 4) Accept (yes or no); nº of days/wk accepted (1, 2 to 3, 4 to 5); consumes school meals and buys food (yes or no); nº of days/wk you buy food (1, 2 to 3, 4 to 5) | Acceptance “Accepted” = ≥85% (Adding “liked” and “loved”) Rest ingestion index “Accepted” = ≥90% Adherence and acceptance | Most students (81%) accept school meals. Of these, 46% consume 4 to 5 times a week. The information obtained through the hedonic scale and the adherence frequency questionnaire showed that the most accepted foods were rice and beans (both 57%), and the least accepted was steak (5%). The most rejected food was beet (28%), and the least rejected was sweet potato (3%). |

Food temperature was considered adequate for 89.5%, 88.8%, and 87.9%, and the amount was “good/sufficient” for 54.7%, 57%, and 63.4% of students, respectively. For adherence, it was high for lunch (95%) and afternoon snacks (78.0%) and low for morning snacks (44%). Factors associated with non-adherence were: (i) the presence of > four people in a household, (ii) having meals in a refectory, (iii) the meal location being considered uncomfortable, and (iv) a negative evaluation of utensils used in eating meals. Factors associated with non-acceptance were age >10 years, female sex, the negative evaluation of utensils used in meals, and inadequate food temperature. |

Lee (2019) South Korea [98] | To compare student consumption of school meals by school level, to identify the influencing factors of school meal consumption, and to assess improvement needs of school food service among students | SS: n = 58 TS: Elementary, middle, and high school P: Students (n = 1.441) | 5-point scale (“eat all served” = 1 to “eat none” = 5) and (“very small” = 1 to “very large” = 5) 5-point Likert scale (“strongly disagree” = 1 to “strongly agree”) Less = suggested reasons (n = 11) or More = suggested reasons (n = 8) 5-point scale (“very dissatisfied” = 1 to “very satisfied” = 5) 5-point Likert scale (“very unnecessary” = 1 to “very necessary” = 5) Suggested reasons (n = 16) no total answered through | Consumption and perception of the portion served Reasons for eating: Less (for those who had less than half the portion served) More (for those who had half, or more than half, the portion served) Satisfaction (sanitation, temperature, presentation, taste, variety of menus, portion size, and reflecting student opinions) Needless to improve school food service to increase consumption | A total of 76.1% consumed almost all or all of the meals served. Approximately 58% of students perceived the school lunch portion size as adequate. The main reason for consuming half or more than half of the portion was “because the food tastes good” (3.65), and consuming less than half was “because the food is not tasty” (3.76). The mean satisfaction scores for all students evaluated were sanitation (3.80), temperature (3.72), presentation (3.64), taste (3.63), variety of menus (3.56), portion size (3.43), and reflecting student opinions (3.31). All independent variables were significant predictors of meal consumption. Students with higher scores for eating behavior, satisfaction with food service, environmental protection, and more positive behavior scores and attitudes toward school meals consumed significantly more meals. Regarding improving the school food service, “serving food that students prefer” (4.18 points) was the most prevalent. |

Most responded “sometimes” for “lunch menu includes foods they like”, “like the way the food looks”, “like the smell of the food looks”, “like the vegetables in the serving line”, “vegetables in serving line look good”, “enough food choices”, for “like the taste of the food” and “likes the whole grain foods available”. Most students responded “always” for “serving line has milk they like” (60%), “like the fruits in the serving line” (37%), and “fruits in serving line look good” (42.7%). For “saltiness of food served” and “amount of food (portions)” 79.4% and 72.7% responded “about right”, respectively. Regarding the general satisfaction with school lunches and breakfast, 36% and 56.5% of students liked it, 52% and 37.9% reported that it was only okay, and 12% and 5.9% reported they did not like it, respectively. In the parents’ view of school lunches for “healthiness”, 62.8% considered “somewhat healthy”. About “child likes”, 50.9% reported that they “agree somewhat”, and about “satisfaction”, 52.1% said they were “somewhat satisfied”. A total of 19.4% were “somewhat” or “very dissatisfied”, and the main reason for dissatisfaction was “poor quality/taste”. |
Assan et al. (2020) India [100] | To examine the impact of an internationally funded Indian foundation’s mid-day meal (MDM) school feeding program on educational access, performance, participation, and well-being of the beneficiaries | SS: n = 62 TS: Elementary, middle P: Students (n = 1.338), teachers (175) | 4-point hedonic scale (“poor”, “good”, “very good”, “excellent”) 3-point hedonic scale (“not satisfied”, “satisfied”, “very satisfied) | Satisfaction level Quality (general, taste, flavor, variety, presentation) Quantity of meal/potion served (general, freedom to ask more, quantity per week) | Adding the percentages of “good”, “very good” and “excellent”, students and teachers rated the general quality (97 and 99%), flavor (96 and 99%), and taste (95 and 97%), respectively. As for the presentation of the menu, only 1% and 2% were dissatisfied. Already 9% of both were dissatisfied with the variety of the menu. Regarding quality improvement, the majority, 27% of students and 56% of teachers, suggested options to increase menu variation. As for the amount of food, 2% of the students and 5% of the teachers did not find an adequate amount. Already weekly, 1% and 6%. As for the “freedom to ask for more”, 2% of students and 1% of teachers were dissatisfied. |
Joyce et al. (2020) USA [101] | To compare the acceptability and feasibility of best practice (BPSL, optimizing DQ) with typical school lunches (TSL, meeting minimum NSLP standards) served separately and concurrently | SS: Local school districts (n = 4) TS: Elementary school P: Students (n = 36) | 5-point Likert scale (with smiley faces) (“very bad” = 1 to “very good” = 5) and Any comments? Average total plate waste value and photos Hunger scale (“How hungry are you?”) 5-point Likert scale (stuffed = 1, full = 2, comfortable = 3, hungry = 4, ravenous = 5) | Acceptability Taste test (appearance, smell, taste, and desire to serve at school) Plate waste Change in hunger (level of satiety before and after consumption) CH: pre-meal hunger subtracted from post-meal hunger | The typical school lunch (TSL) had the average scores: taste (4.6), smell (4.3), appearance (4.4), and serving at school (4.5). The average total meal waste was 47.8%, with the highest waste for milk (68.8%) and the lowest for proteins (28.3%). |
Peres et al. (2020) Brazil [102] | To evaluate, through sensory analysis, the acceptability of goat’s milk over cow’s milk in public schools in the municipality of Bambuí, MG | SS: n = 2 TS: Elementary, high P: Students (n = 330) | 5-point hedonic scale (“liked it a lot = 5 to “disliked it very much" = 1) | Acceptability Acceptance test | Cow’s milk (C) had an average score of 3.77 on the acceptance test. When checking the preference for school, an average of 3.88 (school 1) and 3.71 (school 2) was observed. |
Guimarães (2020) Brazil [103] | To assess the nutritional quality and acceptability of school food cards in a municipality in Bahia | SS: n = 5 TS: Elementary, middle P: Students (n = 445) | 5-point hedonic facial scale (1st to 3rd grade) or 5-point hedonic mixed facial scale (4th and 5th grade) 5-point hedonic verbal scale (6th to 8th grade) (“hated” to “loved’) | Acceptance | There was good acceptance of school meals among students. When asked about the foods they would like included on the menus, of the 445 students who responded, they included fruit salad (41.3%), hot dogs (39.2%), and soda (28.12%). The least accepted menu was coconut hominy (3.91–61.6%), and the most accepted was carrot cake with yogurt (4.62–92.4%). |
Donadini et al. (2021) Italy [104] | To explore meal liking and to understand mechanisms behind meal acceptance | SS: n = 1 TS: Preschool P: Students (n = 60) | 5-point nongender horizontally oriented facial scale Verbally articulated the to dish liking (“super-bad”, “bad”, “so and so”, "good”, “super-good”), indicated the facial icon, and inserted a scoring card into 1 of 5 boxes lined up in front of him/her. Referring to the score of (1 = “dislike much” to 5 = “like very much”) | Acceptance Liking (overall) and reported familiarity by parents (about the served dishes) | As for the taste of the dishes, the average was 4.1. Among the first course, second course, side dish, and dessert or fruit, the dishes with the highest and lowest scores were: risotto with saffron (4.9) and pureed vegetable soup (4.4); braised loin (4.3) and oven-baked breaded plaice (3.7); raw carrots (4.1) and raw fennels (2.6); delicious golden apple (4.7) and red-orange juice (3.4), respectively. The familiarity reported by the parents showed that cheese and tomato pizza and risotto with saffron (4.7) were familiar to the children, and raw fennels (2.7) were the least familiar. Taste scores correlated with food neophobia, familiarity, sweetness, odor, and flavor intensity. The mother’s taste was most strongly associated with the child’s taste. |
Araya and Castillo-Montes (2021) Chile [105] | To determine the degree of acceptability of prepared lunches that are given to students by the SFP and its association with economic losses | SS: n = 5 TS: Elementary, middle, and high school P: Students (n = 528) Food handlers and teachers in charge of the SFP (n = 5) | 3 instruments: (1) 9-point hedonic scale (1 = “dislike extremely” to 9 = “like extremely“) The results were grouped into four categories of preferences (A, B, C, and, D) where category A presents the highest preference and the following ones in descending order up to D. and The students were asked about their perceptions of the organoleptic characteristics: Smell, flavor, appearance, and consistency (good, regular, or bad) to Salt content (with salt−without salt), cooking (adequate−inadequate). temperature (hot–cold) and quantity of the portion (sufficient−insufficient) (2) Sorting test: sensory estimation analysis to determine the difference in magnitude according to the degree of preference of the six preparations, based on the criteria of food handlers and teachers in charge of the PAE, who ordered the preparations according to the degree of preference they observed in the students. The ordering test scale was scores of 1 to 6 (1 = highest preference and 6 = least) (3) The percentage of intake was determined in quartiles (25, 50, 75, and 100%) about the amount of main course not eaten (salads and desserts were not considered) | Acceptability | The thinly sliced beef with noodles was found to have the highest preference and the lowest-ranked meals were beans with noodles and fish cake with mashed potatoes (p < 0.05). Preparations with lower acceptability represented 82.2% of economic losses and were mainly beans. The results confirm a low intake of fish and vegetables, that taste characteristics due to low salt content affect preferences, and that there was a direct relationship between intake and economic loss. |
Donadini et al. (2022) Italy [106] | To explore pre-schoolers liking of meals and of individual dishes served in a meal by tasting actual foods in the natural setting of the school canteen | SS: n = 1 TS: Preschool P: Students (n = 127) Teachers (n = 3) | 5-point nongender horizontally oriented facial scale (super-bad to super-good) a one-on-one interview with the teachers The child declared loudly how much s/he had liked the meal using the scale descriptors and indicated to what facial icon the meal belonged by pointing to one of the five boxes lined up in front of him/her Visual estimation (by elected teachers) 7-point scale (all, one mouthful eaten, ¾, ½, ¼, one mouthful left, none) Maximum score = no food remained on the plate Intermediate score = ¾, ½, ¼ of the food, or just a bit of the food remained Minimum score = the plate was left untouched Percentage of the uneaten food for each child and each dish: estimated to the nearest 10% increment (considering the appearance of full servings) The scores on the scale were converted to weight estimates of plate waste for all servings based on initial weights: multiplying the initial weight of each serving by the percentage value corresponding to the score given on the scale (7 = 100%; 6 = 90%; 5 = 75%; 4 = 50%; 3 = 25%; 2 = 10%; 1 = 0%) | Overall liking Plate waste The leftovers of each child and vegetable and fish items were recorded, and the relation between the uneaten amount, liking of and familiarity to these items was studied | Liking varied (p < 0.001) across meals and individual dishes. The most appreciated meals included: solid starch-based dishes with meat sauce and cheese, lean poultry meat, roast potatoes, fruit yogurt, fresh seasonal fruit, or fruit ice cream. Least liked meals included vegetable soup (with pasta or rice), pasta with zucchini or legumes, seafood, or cheese. Fish and cheese were moderately liked, and vegetables were liked the least. The first and second courses contributed most to overall meal acceptability. Liking of side dishes was uncorrelated to individual meal liking in most children. Children liking and reported familiarity by parents successfully predicted the amount of food eaten. Girls were more familiar with vegetable dishes and likelier to like and consume these dishes than boys. Children’s sex did not affect fish consumption. |
Pinto (2022) Brazil [107] | To evaluate the effectiveness of a multicomponent intervention in adherence and acceptability to school meals (A) | SS: n = 3 TS: Elementary and middle school P: Students (sample estimates: n = 90 for acceptability, and n = 396 for adherence) | One school in each group: Control group: no intervention Group 1: environmental modifications and addition of a self-service system Group 2: environmental modifications, the addition of a self-service system, and the inclusion of new dishes in the menu 5-point mixed facial hedonic scale (4th to 5th grade) 5-point verbal hedonic scale (6th to 9th grade) (“hated” to “loved”) Objective question (n = 1) “Do you eat the lunch offered by the school?” with six answer options (“never or almost never”; “1x/week” to “4x/week”; “every day”) | Acceptability index Average acceptability: Positive: ≥4 Negative: <4 Adherence ≥3 times/week | There was a significant increase in the acceptability index in the groups of preparations based on meat and sweets among participants in intervention school 1 and intervention 2, compared to the control school over time. The increase in fruit acceptability was greater among participants in intervention school 2 when compared to those in intervention school 1. Reduction in the acceptability of bean-based preparations was observed between intervention school 2 and intervention 1 and control schools. An increase in adherence to school meals was observed in the intervention school 1 vs. control school and a greater increase in intervention school 2 vs. control school. |
Pinto (2022) Brazil [107] | To identify the factors that could contribute to the low adherence and acceptability of the food offered at school (B) | SS: n = 3 TS: Elementary and middle school P: Students and cooks (n = 5 to 8 people in each group) | Two focus groups (with students from the one school): The students who report the consumption and non-consumption of the meals offered Subjective questions (n = 7, each) One focal group (with cooks from the three schools): Subjective questions (n = 6) Regarding self-knowledge about the role of cooks in the school unit; perception of adherence and acceptability of food by students; motivation for non-consumption of preparations by students; way of preparing and distributing meals and what actions could be taken to make food more attractive to students | Adherence and acceptability | Based on the perceptions about the reasons for non-adherence to school meals reported in focus groups carried out with lunch ladies and schoolchildren, the standardization of gastronomic techniques was possible, leading to changes in the dishes that were part of the menus of the schools and also the creation of new ones. These new menus were offered for group 2 of the previous study. |
