Yogurt and Concentrated Yogurt Preparation
Five batches of stirred-type goat milk yogurt were made by adding 5% (w/w) previously activated lyophilized yogurt
culture containing S. thermophiles, L. bulgaricus, and L. achidophylus. Incubation was done in a tightly closed stainless
steel container for 5 hours at 40oC. Samples of yogurt were collected and stored in glass containers in a refrigerator at 5oC,
and ready for fat extraction. The remaining yogurt was transferred into a clean cheese-cloth, tied up and hung in a cold room
