What is Yogurt

Yogurt are "live and active cultures" referring to the living organisms, Lactobacillus, bulgaricus and treptococcus thermaophilus, which convert pasteurized milk to yogurt during fermentation.

Note that the milk is pasteurized before culturing to remove any harmful bacteria. The process is very similar to that used when making beer, wine or cheese, in that beneficial organisms ferment and transform the basic food. This fermentation process is what creates yogurt, with its unique taste, texture and healthful attributes.
