Abstract

This study aimed to determine effect of different yoghurt starter concentrations and the addition of mango juice (Mangifera indica L.) on the characteristics of soy milk yoghurt (Glycine max). This study used a Factorial Completely Random Design (CRD Factorial) method with two treatment factors namely yoghurt starter concentrations (3% and 5%) and mango juice addition (0%,10%, and 20%). Each treatment was replicated three times. The parameter observed were physical characteristic (color and viscosity), chemical characteristics (pH, total acidity, total soluble solids, ash, and protein content), and sensory characteristic (taste, color, and aroma). The result showed yoghurt starter concentration had a significant effect on the viscisity and pH of soy milk yoghurt. Mango juice addition had a significant effect on the lightness, yellowness, and viscosity of soy milk yoghurt. Interaction between yoghurt starter concentration and addition of mango juice also had a significant effect on the viscocity of soy milk yoghurt. The best treatment was determined using the De Garmo method, which was (5% yoghurt starter concentration and 20% mango juice addition), with sensory score of 3.20 for taste (like), 3.64, for color (like), and 3.52 for aroma (like). As wll as a viscosity 947.5 m.Pas. pH 4.84, total acidity 0.62%, total soluble solids 14.3⁰Brix, ash content 1.0%, and protein content 7.96%. Keywords: soy milk, yoghurt starter, mango juice, yoghurt.
