Soya milk is made by soaking soybeans, grinding them with water. The fluid which results after straining is called soya milk. Soya milk is preserved in aseptic cartons. Soya milk available in the market is flavored and fortified with extra calcium or vitamins.

Plain soy milk is very nutritive: it's an excellent source of high quality proteins, isoflavones and B-vitamins. Soy milk is free of the milk sugar (lactose) and is a good choice for people who are lactose intolerant. Also, it is a good alternative to those who are allergic to the proteins of cow's milk.
