Annual legume (Glycine max, or G. soja) of the pea family (see legume) and its edible seed.

The soybean plant has an erect, branching stem, white to purple flowers, and one to four seeds per pod. It was probably derived from a wild plant of East Asia, where it has been cultivated for some 5,000 years. Introduced into the U.S. in 1804, it began to be farmed widely as a livestock feed in the 1930s, and the U.S. is now the world's foremost soybean producer. Economically the world's most important bean, the soybean provides vegetable protein for millions of people and ingredients for hundreds of chemical products, including paints, adhesives, fertilizers, insect sprays, and fire-extinguisher fluids. Because soybeans contain no starch, they are a good source of protein for diabetics. Processed for food, soybean oil is made into margarine, shortening, and vegetarian cheeses and meats. Soybean meal serves as a high-protein meat substitute in many food products, including baby foods. Other food products include soybean milk, tofu, salad sprouts, and soy sauce.

Soybeans (Glycine max)

(Glycine max, or G. soja),also called  Soja Bean, or Soya Bean,  
 annual legume of the Fabaceae family and its edible seed, probably derived from a wild plant of East Asia. The soybean is economically the most important bean in the world, providing vegetable protein for millions of people and ingredients for hundreds of chemical products.

      The origins of the soybean plant are obscure, but many botanists believe it to have derived from Glycine ussuriensis, a legume native to central China. The soybean has been used in China for 5,000 years as a food and a component of medicines. Soybeans were introduced into the United States in 1804 and became particularly important in the South and Midwest in the mid-20th century.

      The most nutritious and most easily digested food of the bean family, the soybean is one of the richest and cheapest sources of protein. It is a staple in the diet of people and animals in numerous parts of the world today. The seed contains 17 percent oil and 63 percent meal, 50 percent of which is protein. Because soybeans contain no starch, they are a good source of protein for diabetics. In East Asia the bean is extensively consumed in the forms of soybean milk, a whitish liquid suspension, and tofu (q.v.), a curd somewhat resembling cottage cheese. Soybeans are also sprouted for use as a salad ingredient or as a vegetable and may be eaten roasted as a snack food. Soy sauce, a salty brown liquid, is produced from crushed soybeans and wheat that undergo yeast fermentation in salt water for six months to a year or more; it is a ubiquitous ingredient in Asian cooking.

      The soybean is an erect, branching plant ranging in height from several centimetres to more than 2 m (6.5 feet). The self-fertilizing flowers are white or a shade of purple. Seeds can be yellow, green, brown, black, or bicoloured. In the United States, commercial varieties have brown or tan seeds, with one to four seeds per pod. The soybean may be cultivated in most types of soil, but it thrives in warm, fertile, well-drained, sandy loam. The crop is planted after all danger of frost is past. Maturing during September and October, soybeans are usually harvested mechanically in the United States, after the leaves have fallen off the plant and the moisture content of the seed has dropped to 13 percent, permitting safe storage.

      In the 1980s the United States was the world's principal producer, followed by Brazil and China. Illinois is the leading producer among U.S. states. Ninety-eight percent of the U.S. crop is used for livestock feed.

      Modern research has led to a remarkable variety of uses for the soybean. Its oil can be processed into margarine, shortening, and vegetarian cheeses. Industrially, the oil is used as an ingredient in paints, adhesives, fertilizers, sizing for cloth, linoleum backing, insect sprays, and fire extinguisher fluids, among other products. Soybean meal serves as a high-protein meat substitute in many food products, including baby foods, and can be imparted with a meatlike texture for increasing the cooked yield of such products as ground meat and bologna. In the late 20th century, the versatile, nutritious soybean, widely cultivable and readily exportable, played an integral role in attempts to alleviate world hunger.
