Karakteristik Fisikokimia Dan Mikrobiologi Pada Yoghurt Susu Uht Menggunakan Starter Mikroenkapsulasi Dengan Metode Back Slopping

ABSTRACT

Yoghurt is a semisolid fermented milk product such as ultra high temperature (UHT) milk that is processed with the help of lactic acid bacteria (LAB). The lactic acid bacteria used in this research were Lactobacillus plantarum TMW 1.1623 and Streptococcus thermophillus which have the characteristics of probiotic bacteria. These bacteria were used in the manufacture of yoghurt starter that is microencapsulated. A simple effort that can be made is by making yoghurt using the back slopping fermentation method. This research aimed to determine the physicochemical and microbiological characteristics of UHT milk yoghurt using a microencapsulated starter with back slopping fermentation method up to a certain cycle. This research was conducted experimentally using a completely randomized design (CRD) with yoghurt derived starter as a treatment and four replications. The results of variance in this research showed that UHT milk yoghurt using a microencapsulated starter with back slopping fermentation method was able to survive until the 7th cycle. The more cycles of yoghurt derivatives using the back slopping fermentation method, the more the physicochemical and microbiological characteristics produced decrease, but LAB activity was still able to survive until a certain fermentation cycle, namely in the 7th derivative of T7 treatment. The physicochemical and microbiological characteristics produced in this research were having total LAB values ranging from 08.69–12.07 log CFU/mL with pH of 4.72–5.03, total titrated acid of 0.74–1.24%, viscosity of 285, 15–2417.25 cP, and WHC 16.11–46.73%.
