Successful marketing of fresh fruits requires careful attention to the details involved in postharvest handling (PH), which protects fruit’s quality and nutritive and economic value. This study assessed the PH practices of sweet orange marketers in Benue State. Six (6) major orange markets were purposively selected. Thereafter, a total of 104 marketers were randomly sampled. The data were collected using an interview schedule and analysed using the frequencies, percentages, means, Chi-squares, and Pearson’s Product Moment Correlations at α_0.05. The knowledge of PH practices and the level of PH practice utilisation were high. Marketers’ age (r = −0.220, p < 0.05), the use of sacks for packaging (χ² = 23.314, p < 0.01), knowledge of PH (r = 0.272, p < 0.01), and attitudinal disposition towards PH (r = 0.492, p < 0.01) significantly influence the utilisation of PH practices. This study recommends the generation of awareness and sensitisation among marketers by horticultural crop institutions on improved preservation and packaging methods for sweet oranges. Full article

Maize flour (MF) is a cheap and common cereal product that can be used in various foods. However, different processing methods can affect its quality and suitability for different purposes. This study compares the effects of three processing methods (grain non-soaking (GNSM), grain soaking (GSM), and nixtamalization (NIX)) on the nutritional, pasting, and functional properties of MF. MF samples (GNSM-MF, GSM-MF, and NIX-MF) were analyzed using standard laboratory techniques. Protein and moisture contents ranged from 9.34 to 10.12% and 5.35 to 7.05%, respectively, with NIX-MF having significantly (p < 0.05) higher protein content. Calcium, iron, and zinc contents ranged from 3.64 to 10.91 mg/g, 3.69 to 7.64 mg/g, and 1.45 to 1.92 mg/g, respectively. GNSM-MF had the lowest calcium content. Peak, breakdown, final, and setback viscosities were 980.25–2904.15 RVU, 91–1147 RVU, 778–1210 RVU, and 331.5–919 RVU, respectively. GSM significantly (p < 0.05) increased peak, breakdown, final, and setback viscosities. Water-holding capacity (WHC), emulsifying capacity (EC), and oil absorption capacity (OAC) values of MF ranged from 78.93 to 111.95%, 4.97 to 42.18%, and 160.27 to 186.13%, respectively. High protein and calcium contents in NIX-MF make it a nutritious option for pregnant women and children. GSM-MF might be incorporated into snacks, complementary foods, and puddings. This study provides insights into appropriate selection of maize flour processing methods based on food application. Full article

The current rising food prices, influenced by importation costs, the global food crisis, as well as pre- and post-harvest losses, have contributed majorly to malnutrition and food insecurity. Therefore, utilizing technologies that harness our indigenous agro-products as composite flours to develop functional foods will address these issues. In this study, dry raw samples of perishable and healthy yellow potato, yellow maize and pigeon pea were obtained from the agricultural development program, Edo State, Nigeria, and authenticated and processed into gluten-free fermented composite flours. The flours were profiled physicochemically and nutritionally, providing valuable insight into their multiple benefits. An experimental design software (Design Expert 13.0.) was applied to achieve optimum blended flours regarding the ratio of sweet potato–pigeon pea–maize, and mix 5 (67.70:20.00:12.31) displayed more outstanding attributes than other blends for the production of biscuits, bread and cakes using creaming and mixing methods. Various standard tests for flours and products were appropriately carried out to evaluate the proximate, techno-functional, mineral, antioxidant, anti-nutrient, sensory and color values. Individual antioxidant parameters were improved across all products compared to wheat-based products (control) under the same production conditions, showing a statistical significance at p < 0.05. A similar trend was observed in the proximate, anti-nutritional and mineral contents, while all products had a desirable color outlook. A sensory evaluation revealed the general acceptability, while an in vivo animal experimental model revealed that all animals fed with the various product samples gained weight with improved general body organs and no evidence of disease. This research underscores the potential of harnessing agri-value chain approaches in developing functional foods and promoting food security. Full article

This study explored food habits and traditional practices related to sorghum cultivation in Benin. Based on data collected from 289 producers, statistical analysis revealed that sorghum is mainly consumed as porridge (97.92%), paste (91.69%), akassa (40.48%), and used as fodder (30.45%). Additionally, its leaves are used in the treatment of anemia and malaria (40.48%), while its stems serve in shelter construction (55.36%). Factorial analysis shows that these uses vary across sociocultural groups: the Kotokoli, Lokpa, Yom, Mokolé, and Idatcha favor food consumption, the Bariba use it for medicinal purposes, and the Fulani transform it into a local beverage. These findings highlight the need to tailor sorghum breeding programs to sociocultural needs and current climate challenges. Full article

The Kponan yam (Dioscorea cayenensis-rotundata) is a culturally and economically important crop in Côte d’Ivoire but faces significant post-harvest losses, reducing farmers’ and traders’ incomes. This study aimed to identify strategies to minimize these losses during storage. To this end, Kponan yams from Bondoukou, Bouna, and Kouassi-Kouassikro, key production areas, were grown in experimental plots and monitored over three months in both field and warehouse storage. The results showed that yams harvested in Kouassi-Kouassikro (2.53 ± 0.06 kg) and Bondoukou (2.37 ± 0.09 kg) were heavier than those from Bouna (2.01 ± 0.11 kg). Storage conditions influenced spoilage: yams stored in pits had lower alteration rates (40.00% to 48.57%) compared to those stored under straw huts or trees (100%). In warehouses, alteration rates ranged from 72.29% (Bondoukou) to 100% (Kouassi-Kouassikro), with rot rates varying from 47.05% to 70.00%, respectively. Weight losses varied from 15.15% to 36.67% in warehouses versus 8.47% to 42.86% in field storage. These results underline the importance of storage methods, with pit storage significantly reducing deterioration. Full article

Cassava is an essential staple crop in developing nations, ensuring food security and generating income for smallholder farmers. The lack of modern drying technology in rural regions requires effective strategies to reduce post-harvest losses and improve product quality. This study introduces a biomass-powered cabinet dryer designed to produce high-quality cassava flour (HQCF), featuring a heat exchanger, blower, and drying chamber constructed from locally sourced materials. The drying chamber contains two racks, each equipped with 10 trays, accommodating 40 to 80 kg of wet cassava mash per batch. The dryer, operating at temperatures between 50 and 115 °C for a duration of 10–120 min, decreased moisture content from 38.21% to around 11%. Drying efficiencies varied from 59.22% to 88.24%, whereas biomass efficiencies ranged from 3.0% to 4.0%. The results demonstrate the dryer’s efficiency in drying, while the study emphasizes the necessity of customized technical solutions to assist rural populations in cassava-producing areas.

The effects of germination (fresh germinated soybean [SG1F]) and post-germination drying (dried germinated soybean [SG1S]) on the crude protein (CP) levels, aflatoxin content, survival, and growth performance of Nile tilapia fry (Oreochromis niloticus) were evaluated. Raw soybean (SC) and roasted soybean (ST) served as controls. Laboratory analyses revealed CP contents of 11.74%, 38.72%, 38.42%, and 34.72% for SG1F, SG1S, RT, and RS, respectively. Aflatoxin levels were 2.3 µg/kg for SG1S, 1.66 µg/kg for RS, 1.60 µg/kg for RT, and 0.00 µg/kg for SG1F. Experimental diets, formulated to be isoproteic (35.44%) and isolipidic (8.73%), were prepared using flour from these soybean treatments and tested on tilapia fry with an average initial weight of 11.86 ± 2.15 g. The study was conducted in a completely randomized design with three replicates in 1 m³ tanks stocked at 35 fry per tank over 56 days. Weight gains were 23.40 ± 10.21 g, 18.93 ± 8.67 g, 16.30 ± 9.92 g, and 16.07 ± 5.55 g for RT, RS, SG1S, and SG1F, respectively. Survival rates were 100%, 90.67%, 89.33%, and 88% for SG1F, RS, RT, and SG1S, respectively. Daily growth rates showed a consistent upward trend for all diets from the start to the end of the experiment. Full article

Rice is a staple food in Côte d’Ivoire, but parboiling remains a weak link in the local rice value chain. Parboiled rice has superior nutritional and physical properties compared with white rice. In 2017, AfricaRice introduced the “Grain quality enhancer, Energy efficient, and durable Material” (GEM) parboiling system in Côte d’Ivoire to address these challenges. This study evaluated the rice value chain, parboilers’ perceptions of GEM technology, and its role in upgrading the rice value chain. Using two survey types (parboiler association level (focus group) and parboiler household level), 179 rice parboilers and 77 key players were randomly sampled and interviewed in Côte d’Ivoire. We used descriptive statistics and the parboiler budget for the profitability analysis. The results show that parboiling, primarily undertaken by women, is profitable in Côte d’Ivoire. Parboilers identified the key advantages of the GEM system, including improved rice quality, higher output rates, better nutritional value, and the ability to parboil larger volumes of rice. GEM technology enhanced rice quality, increased parboilers’ incomes, and reduced energy costs by 22.3%, saving an average of 73,090 FCFA per ton of parboiled paddy. The study recommends scaling up GEM technology through local fabricator training and broader dissemination in rice-growing regions to further strengthen the rice value chain in Côte d’Ivoire.

The aim of this study was to provide information on post-harvest losses (PHLs) along the main value-added chains in the soybean industry, and on farmers’ strategies for reducing these losses in Benin. Data were collected using a subjective method (questionnaires) from 152 direct actors in the soybean value chain and an objective method (technological monitoring using technological monitoring sheets) from 27 processing units using a two-stage sampling technique in eighteen of the country’s municipalities. The data were analyzed using descriptive statistics. The results revealed that post-harvest losses in soybean value chains ranged from 0.03% to 7.98%. The highest loss percentages were 7.98% (production), 10.0% (processing), and 4.27% (marketing), and were obtained during the subjective measurements. The link most affected by PHL was the production link. These losses were mainly observed during threshing, winnowing, sorting, and harvesting operations. The main causes of these losses were poor mechanization and a lack of skills for post-harvest operations. The main strategies developed by players to cope with this situation remained traditional (timely harvesting, use of appropriate equipment, and good storage practices). However, additional efforts in terms of infrastructure, adapted subsidies/credits, and recruitment of specialists are needed to mechanize the operations most sensitive to losses and to reinforce the capacities of agricultural actors in order to considerably reduce post-harvest losses.

Smoked chicken products from the Nigerian Stored Products Research Institute and three locations in Ilorin, Nigeria, were analyzed for polycyclic aromatic hydrocarbons (PAHs) using gas chromatography. Total PAH levels ranged from 490.893 to 509.064 μg/kg across samples, with benzo(α)pyrene levels (0.947–1.072 μg/kg) within the safe limit of 2 μg/kg. However, PAH4 levels (477.771–491.757 μg/kg) exceeded the European Union’s safe limit of 30 μg/kg. Mean Estimated Daily Intake, Carcinogenic Risk, and Toxicity Equivalent Factor were 0.299 µg/kg/day, 45.341, and 1.443, respectively. Regular monitoring and enforcement of quality control standards are crucial for consumer safety while promoting best practices across the industry. Full article

The utilization of modified starches derived from ginger, sweet potatoes, and maize has been employed as a strategy to reduce the oil content in mayonnaise formulations. Amylose–lipid complexes and the native starches were synthesized, characterized, and subsequently incorporated into various mayonnaise formulations, replacing 50 and 80 percent of the oil. The sensory analysis showed that the mayonnaises produced with 50% and 80% modified corn starch were particularly well received. However, when compared to conventional mayonnaises, the viscosity of the mayonnaises prepared with 50% and 80% modified maize starch was found to be remarkably low. This outcome demonstrates that when preparing low-fat mayonnaise, it is not possible to substitute tuber starches for fat. Full article

Peanut production in Benin has experienced impressive growth, from 69,222 tons in 1989 to 156,901 tons in 2018, despite the liberalization of the sector, which has deprived it of significant public support. This ethnographic study conducted in Ouessè aims to understand this evolution using the path dependency theory. Semi-structured interviews were conducted with several actors, including producers, collectors, traders and processors. The results show that these actors and private microfinance have reappropriated the historical past of peanuts in the commune of Ouessè, as well as the previous orientations of agricultural policy, to reorganize the financing, collection and marketing of peanuts in order to meet the growing demand from processing units.

Among the factors threatening food security in Nigeria are poor access to credit facilities, the high cost of inputs, and poor processing and storage. Cereals and grains are among the staple food crops highly consumed by Nigerians. In this study, multi-stage sampling procedure was used to select 1200 registered rice processors from Agricultural Development Programme zones in the Nigerian states of Lagos, Oyo, Ogun, Ondo, Osun, and Ekiti, and a structured questionnaire was used to obtain data on primary, secondary, and tertiary postharvest operations. The data were analyzed using descriptive statistics and Pearson Product Moment Correlation. The results showed that the majority (65.1%) of the respondents were male, 54.5% were 30–60 years old, 86.9% were married, 96.3% had been formally educated, and 99.9% processed, 71.5% packaged, and 79.4% stored more than 5001 kg of rice monthly. The majority (85.9%) of the respondents had no knowledge of rice moisture content and still used local means of rice processing, while 14.1% of the respondents used modern means of rice processing. We concluded that stored local rice was still subject to more wastage, spoilage, and losses due to the poor processing, packaging, and storage methods used in the study area. We recommend the adoption of modern and suitable rice technologies for processing, packaging, and storage. Furthermore, credit facilities should be made available, and inputs should be subsidized for rice farmers and processors. Full article

Abstract

Rice milling in Sub-Saharan Africa (SSA) remains highly dependent on water availability and favorable weather conditions, making local millers vulnerable to water- and weather-related pressures (WWrP). This study examines how rice millers in Makurdi and Adikpo, Benue State, Nigeria, adapt to these pressures. [...] Read more.

Rice milling in Sub-Saharan Africa (SSA) remains highly dependent on water availability and favorable weather conditions, making local millers vulnerable to water- and weather-related pressures (WWrP). This study examines how rice millers in Makurdi and Adikpo, Benue State, Nigeria, adapt to these pressures. Data were collected through snowball sampling involving 21 rice millers and two workshops attended by 14 millers. Content and thematic analyses of data were carried out using NVivo 11. Findings indicate that rice milling operations are highly exposed and sensitive to flooding, excessive wetness, dryness, high humidity, and water scarcity. These pressures are likely to intensify due to climate change and pronounced climate variability. To adapt, millers employ endogenous strategies, including temporarily relocating or evacuating mills, rotating drying schedules, modifying drying methods, reducing or suspending parboiling during floods, and digging wells. In spite of these adaptation measures, locally milled rice continues to face issues of poor quality and diminished competitiveness. Consequently, this study highlights upgrading milling technologies and infrastructure, promoting proactive and long-term adaptation measures, and supporting collective adaptation strategies among millers to enhance resilience in the rice value chain.

West Africa’s agri-food systems face a triple burden of malnutrition, climate vulnerability, and structural inefficiencies that compromise nutrition and public health. Despite increased attention to food security, agricultural strategies often prioritize yield over dietary quality. This paper explores the critical role of food processing in advancing Nutrition-Sensitive Agriculture (NSA) and Nutrition-Smart Agriculture (NSmartAg) across West Africa. Drawing on a systems lens, it positions food processing not as a peripheral activity, but as a catalytic mechanism that connects nutrient-dense production with improved consumption outcomes. Food processing can reduce post-harvest losses, preserve micronutrients, extend food availability, and foster inclusive value chains particularly for women and youth. Yet, persistent challenges remain, including institutional fragmentation, infrastructure gaps, and limited financial and technical capacity. This paper proposes a conceptual framework linking food processing to NSA and NSmartAg objectives and outlines operational entry points for implementation. By integrating processing into agricultural policies, investment, education, and monitoring systems, stakeholders and policymakers can reimagine agriculture as a platform for resilience and nutritional equity. Strategic recommendations emphasize multisectoral collaboration, localized solutions, and evidence-informed interventions to drive the transformation toward sustainable, nutrition-oriented food systems.

West Africa faces persistent food and nutrition insecurity despite agricultural efforts, exacerbated by population growth, climate change, and socio-economic vulnerabilities. This study argues that integrating food processing principles with nutrition-sensitive agriculture (NSA) and nutrition-smart agriculture (NSmartAg) offers a transformative solution for human health. Therefore, we delineate these interconnected concepts and highlight their synergistic potential for a nutrition-focused food system. Likewise, critical analysis of key regional challenges, including infrastructural weaknesses, policy gaps, and gender inequities, was made prior to identifying significant opportunities for leveraging food processing as a strategic entry point to accelerate the implementation of NSA and NSmartAg. Based on these insights, six strategic pathways are proposed to achieve this objective: (i) integrating food processing into policies; (ii) investing in interdisciplinary R&D that puts nutrition and health benefits at the forefront of desired outcomes along with others; (iii) strengthening farmer and food processor capacities; (iv) improving agri-food infrastructure; (v) fostering multi-sectoral collaboration; and (vi) prioritizing youth engagement and market development. By adopting these integrated strategies, West African countries can build more resilient, equitable, and nutrition-centered food systems, ultimately improving public health outcomes and fostering sustainable regional development.
