Abstract

The purpose of this study was to determine the effect of sugar concentration and butterfly pea flower extract on the physical, chemical and sensory characteristics of jicama jam. This research was carried out in December 2022 at Chemical, Processing and Sensory Laboratory of Agricultural Products, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University. This study used a Completely Randomized Factorial Design with two treatment factors and each treatment was repeated three times. Factor A, namely the concentration of sugar (55%, 60%, and 65%) and factor B, namely the concentration of butterfly pea flower extract (1%, 3%, and 5%). The data obtained were processed using analysis of variance, the treatment with a significant effect was further tested using the 5% Honest Significant Difference test. The results showed that treatment A (concentration of sugar) had a significant effect on the values of lightness, redness, yellowness, water content, dissolved solids, total titrated acid, and organoleptic jicama jam, while treatment B (concentration of butterfly pea extract) had a significant effect on the values of lightness, redness, yellowness, water content, antioxidant activity, and organoleptic jicama jam. The interaction between sugar concentration and peacock flower extract concentration significantly affected the lightness, redness, and yellowness of jicama jam. The A3B3 treatment (65% sugar concentration: 5% butterfly pea flower extract) was the best treatment for making this jicama jam.
