Karakteristik Yoghurt Susu Sapi Segar Menggunakan Starter Mikroenkapsulasi dengan Metode Back Slopping
Making fresh cow's milk yoghurt requires innovation in fermentation methods to produceamorepotent product. Theback sloppingfermentation method can be used to accelerate fermentation time, production of relevant metabolites and allow the formation of a more consistent product. This research aimed to evaluate the physical, chemical, and microbiological characteristics of fresh cow's milk yoghurt by back slopping fermentation method up to a certain cycle. This study used an experimental method by applying microencapsulated starter into fresh cow's milk into T1 cycle yoghurt (mother starter) so that the number of (n) cycle yoghurt is known. This study used a completely randomized design (CRD) with three replications for each treatment. Parameters observed included acidity (pH), total lactic acid bacteria (LAB), total titratable acid (TTA), viscosity, syneresis, and water holding capacity (WHC). The results showed that the application of the back slopping fermentation method in each cycle of fresh cow's milk yoghurt had an effect on acidity (pH), total titratable acid, viscosity, syneresis, and WHC, but had no effect on total LAB. The use of back slopping fermentation method in fresh cow's milk yoghurt has good quality in all cycles evaluated based on physical, chemical, and microbiological characteristics. Yoghurt with back slopping fermentation in cycles T1 10 produced good quality yoghurt with pH ranging from 3.96 4.4, total LAB 10.32 10.76 log CFU/mL, TAT 2.52 3.48%, viscosity 2430.50 4497.55 cP, syneresis 0.00 0.072%, and WHC 23.99 41.45%.
