Soymilk, a liquid extract is one of soybean products. It is rich in essential mineral salts, fats, carbohydrates and vitamins (Jain, 1998). It is a beverage that offers both refreshment and nutrition and can be labeled as a healthy food because of its composition. It compares favourably with cow milk in properties (Table 1) and can be used in place of cow milk in any recipe where milk is needed (Jain, 1998; Mayhew and Penny, 1998). Generally, soymilk has total solids of 8-10%, protein content of about 3.6%, fat 2.0%, carbohydrate 2.9% and ash 0.5% (Liu, 2005).
