Soy yogurt / Soya yogurt, Soygurt or Yofu is a yogurt made from soy milk. Soy yogurt is made using soy milk, adding yogurt bacteria and sweeteners such as glucose, fructose or sugar. Soy yogurt is an essential food for vegans and for the people with milk allergy or lactose intolerance.

Soy yogurt can be prepared at home using the same method as dairy yogurt. One tablespoon of sugar per 1 liter of unsweetened soy milk may be added to promote bacterial fermentation. Soy milk on its own lacks the lactose or the milk sugar, which is the basic food for the yogurt bacteria.

Soy yogurt may have a slight beany taste when made from freshly prepared soy milk. This taste is less pronounced in the soy yogurt bought from the shops and in the soy yogurt made from commercial soy milk.

Soy yogurt contains less fat than yogurt made with whole milk. This amounts to about 2.7% (the same percentage as soy milk) versus 3.5% in dairy yogurt. However just as dairy yogurt can be made with 2%, 1%, or fat-free milk soy yogurt can also be made from reduced-fat soy milk.
