Soybeans originate from China. Soybean plants were domesticated between 17th and 11th century BC in the eastern half of China where they were cultivated into a food crop. Soybean has been one of the five main plant foods of China along with rice, wheat, barley and millet. Later on soybeans were introduced into several countries such as Japan, Indonesia, the Philippines, Vietnam, Thailand, Malaysia, Burma, Nepal and India. The spread of the soybean was due to the establishment of sea and land trade routes.
Although soybeans are native to Southeast Asia, 55 percent of production is in the United States. Other leading producers of soybeans are Argentina, Brazil, China and India. Much of the US production is either fed to animals or exported, though US consumption of soy by people has been increasing.
Soybeans contain highest protein among all other vegetables exiting in this universe. The protein percentage of soybean is 40. Many derivatives can be obtained from the soybean such as; Soy Milk, Soy Yogurt, Tofu, Soybean Oil, Shoyu, Soy Protein and many other. All the products of soybeans are very much used all over. All products are rich in protein.

Tofu is slightly mild tasting product that easily absorbs the flavors of the other ingredients. Fresh Tofu is usually packaged in water and should be refrigerated and kept in water until used. If the water is drained and changed daily, the Tofu should last for one week. Tofu can be frozen for up to three months.
