Abstract

Background/Objectives: The utilization of natural colorant can improve food appeal. This study determined the potential of Clitoria ternatea flower extract as a substitute for synthetic colorants. Methods: The researchers prepared gummy candies using 100mL aqueous extracts from various weight samples of C. ternatea flowers. Fifty candy eaters with different age brackets were randomly chosen as respondents of this study. The respondents evaluated through the sensorial method the different treatments in terms of taste, texture, color, smell, appearance, and overall palatability using a nine-point scale hedonic scale. The researchers compared the age brackets using the analysis of variance. Findings: Results showed that aqueous extract of Treatment 3 (30 grams) has the highest total weighted average mean (TAWM) of 7.78 level of acceptability with a “Like Very Much” description, followed by the TAWM of 6.57 of Treatment 4 (40 grams) with “Moderately Like” description. In comparison, Treatment 1 (10 grams) has the lowest TAWM of 2.97 with a description of “Dislike Moderately.” The high level of acceptability implies that C. ternatea flower aqueous extract improves the color and appearance of the gummy candies. This study further shows no significant difference in acceptability among the respondents when grouped into age brackets. The researchers conclude that the aqueous flower extract of 30g C. ternatea improved the color and appearance of the gummy candies. Furthermore, it could be accepted by the candy consuming public of various ages. Novelty/Applications (30): The utilization of C. ternatea flower aqueous extract as a colorant improves the acceptability of commercial gummy candies. The use of alternative safe, natural colorants promotes healthy living and sustainable candy production.

Keywords: Clitoria ternatea; gummy candies; level of acceptability; sensorial method; hedonic scale
