*3.1. Traditional Technique of Acceptance Measurement, Familiarity and Purchase Intent*

The mean and standard deviation of sensory attributes, overall liking and familiarity of the energy drinks A and B are shown in Table 2. No significant differences (*p* > 0.05) were found between both the energy drinks for all the sensory attributes (appearance, aroma, taste/flavour, sweetness, bitterness, mouthfeel and aftertaste). There was a significant difference in the overall liking of the energy drinks. Energy drink A had a significantly higher overall liking score (6.79) compared to that of energy drink B (5.98). Based on the chi-square test *X2* (4, *N* = 94) = 5.25, *p* = 0.26, no significant difference was found among the samples. The expected value of the last category of the attribute was more than the observed value; therefore, the result's interpretation was sceptical.

**Table 2.** Sensory attributes, overall liking and familiarity of energy drink A and B after tasting.


Sensory attributes and overall liking of energy drink A and energy drink B were measured by 9-point hedonic scale (1 = extremely disliked and 9 = extremely liked) and familiarity between the energy drinks were assessed with 5-point categorical scale (1 = not at all familiar and 5 = extremely familiar). Bold italicized values indicate that the parameter was significantly different from 0 (*p* < 0.05). \* F value = mean square or mean square error. Effects were considered significant if Pr (probability) > F was <0.05 (bold probability and F value). \*\* Familiarity was analysed by chi-square at a 95% confidence level. a,b Means with different superscripts in each row indicate significant differences (*p* < 0.05).

The frequency at which a consumer's intent to buy energy drinks based on the sensory attributes are shown in Table 3. A total of 68.09% of participants intended to buy energy drink A, while 55.32% of participants expected to buy energy drink B. No significant differences in the purchase intent of energy drink A and B were found.


**Table 3.** Purchase intent frequencies of energy drinks during the tasting session.

Cochran's *Q* is used to find the difference between energy drinks. The table shows a percentage of consumers willing to buy the energy drink after the tasting session of the energy drinks. Different superscript letters in each row indicate significant differences (*p* < 0.05).
