Soy milk also referred to as soy drink or soy beverage is a beverage obtained from soybeans. It is a stable emulsion of oil, protein and water obtained by soaking and grinding soybeans in water. Soy milk contains about same proportion of protein as present in cow's milk. Soy milk contains 3.5% protein, 2% fat, 2.9% carbohydrate and 0.5% ash. Soy milk can be prepared in home with traditional kitchen tools or with soy milk machine. The coagulated protein obtained from this milk can be used to make tofu in the same way as dairy milk is used for making cheese.
