KUALITAS SENSORIS YOGHURT SINBIOTIK MENGGUNAKAN PATI TERMODIFIKASI DARI UMBI UWI UNGU (Dioscorea alata)

Abstract

YOGHURT SINBIOTIK SENSORY QUALITY USING MODIFIED STARCH FROM BULBS UBE PURPLE (Dioscorea Alata). The materials used in this study were 4.800 ml UHT milk, skim milk 8%, 6% sucrose, starch modified from Uwi purple tuber (Dioscorea alata) with a concentration of 0%, 0.1%, 0.2%, 0.3% , 0.4%, 0.5%, distilled water, alcohol, spritus, Thermopilus Streptococcus bacteria, Lactobacillus bulgaricus, Lactobacillus rhamnosus, and materials that were used for sensory testing is mineral water, and cucumber. This study uses a completely randomized design (CRD) with 6 treatments and the panelists were as replications. Organoleptic data measurement using hedonic test using 44 trained panelists. For a highly significant variable followed by HSD test. The variables were the color, aroma, texture, consistency and taste. Results of analysis of variance showed that the administration of the modified starch from Uwi purple tuber (Dioscorea alata) highly significant for color, aroma, texture, consistency and taste. Treatment with modified starch provision of uwi purple tuber (Dioscorea alata) as much as 0,4% of the best value of sensory qualities in the taste and texture of synbiotic yoghurt.
