Soy milk is made by soaking soybeans, grinding them with water. The fluid which results after straining is called soy milk. You can make soy milk at home with basic kitchen tools or with a soy milk machine. Soy milk is most commonly found in aseptic cartons. Most of the soy milk available in the market is flavoured and fortified with extra calcium or vitamins. The most popular flavours are vanilla and chocolate. Some producers add thickeners to their soy milk to give it a mouth feel of cow's milk. Traditionally, soy milk has a beany taste which is well accepted by the Chinese, but less by the Western palate. By using correct processing techniques, this beany taste can be reduced or eliminated. Recently, with the recognition of its health benefits and with its improved flavor and texture, soy milk has now a high and rising acceptance. Sometimes, use is made of protein isolates from soy bean which are mixed with water, oils, sugars, stabilisers to give it a milky appearance. This type of product should be described as soy drink and is not as wholesome as real soy milk. Although soyfoods are widely recognized for their nutritional qualities, interest in soyfoods has risen recently because scientists have discovered that a soy component called isoflavones appears to reduce the risk of cancer. More research needs to be done to determine exactly how isoflavones work, but it appears that as little as one serving of soyfoods a day may be enough to obtain the benefits of this anticancer phytochemical. Traditional soy products such as tofu, tempeh, and soy milk are very high in protein. Tempeh has the highest percentage of protein of the traditional soy products providing approximately 22 grams of protein for each 4 ounce (113 gram) serving. Tofu provides approximately 9 grams of protein for a similar small serving size. The Recommended Dietary Allowance of protein for adult males (aged 25-50) is appoximately 63 grams and 50 grams for adult females (aged 25-50). Soy products can provide a significant portion of one's daily protein needs. It is important to keep in mind, however, that the balance of amino acids (protein building blocks) in soy is not the same as meat. Because soy foods does not have an ideal balance of amino acids, some experts recommend taking in a little extra soy foods and/or combining soy products or legumes with a whole grain dish at meals where other protein (e.g., eggs, fish) is not eaten. The amino acids in whole grains combine well with amino acids in soy and legumes to make a more ideal balance of amino acids. If a person's diet is reasonably-balanced, however, there is usually no need to be concerned about getting enough protein.
