Abstract

This study aims to analyze the differences in shelf life and acceptability of jelly candies made from red dragon fruit flesh extract and red dragon fruit peel extract. The research employed a quantitative approach with a Completely Randomized Design (CRD). The shelf-life test was carried out for 72 days with five untrained panelists by observing mold growth, taste changes, aroma changes, and color changes. The data were analyzed using Analysis of Variance (ANOVA) and followed by the Duncan Multiple Range Test (DMRT) to determine significant differences between treatments. The acceptability test was conducted with 50 untrained panelists using the hedonic test, assessing color, aroma, texture, and taste attributes. The results were analyzed using the t-test to identify differences in panelists’ preference levels. The results showed that mold growth occurred faster in jelly candies made from red dragon fruit flesh extract, while taste and color changes appeared earlier in those made from peel extract. Aroma changes in both treatments occurred at the same time. The ANOVA results indicated significant differences in several shelf-life parameters, while the t-test results revealed significant differences in all acceptability aspects. The mean scores for color (6.43), aroma (6.33), texture (6.17), and taste (6.21) in jelly candies made from red dragon fruit flesh extract were higher than those made from peel extract—color (5.72), aroma (5.91), texture (5.78), and taste (5.77). It can be concluded that jelly candies made from red dragon fruit flesh extract have a relatively shorter shelf life but are more preferred by panelists compared to those made from peel extract.

Abstract

Crackers are one of the types of traditional light snacks that are popular in Indonesia, known for their crispy texture and distinctive flavor, made from a tapioca flour dough mixed with ingredients such as shrimp, fish, or animal skin. They undergo a process of steaming, freezing, thin slicing, drying, and frying until cooked. The purpose of this study is to determine the effect of jicama substitution on sensory quality, seen from color, aroma, texture, and taste. The study was conducted in September–October 2025 at the Culinary Workshop, Department of Family Welfare Science, Faculty of Tourism and Hospitality, Padang State University. The method used was a pure experiment with a Completely Randomized Design (CRD) consisting of 4 treatments and 3 repetitions, namely jicama substitution of 0% (X0), 50% (X1), 60% (X2), and 70% (X3). A sensory test was conducted to assess product quality involving 50 semi-trained panelists. The data obtained were analyzed using ANOVA, followed by Duncan's test if the calculated F value > F table. The study results showed that jicama substitution had a significant effect on each treatment. Treatment X3 (70%) showed the highest score in the yellow color parameter (4.60), X3 (70%) showed the highest score in the characteristic fragrant jicama aroma parameter (4.04). X2 (50%) showed the highest score in the crispy texture parameter (4.82). X3 (70%) showed the highest score in the sweet-savory taste parameter (4.12).
