About Soya

Soyabean is a native of China. The cultivated soyabean (Glycine max) originated from its wild ancestor Glycine ussuriensis, which is presently known as Glycine soja.

The crop is known for its high food value from centuries and it was used for food purposes (milk, douchi, hamanatto, miso, shoyu, doufu, natto, tempeh, soya flour, green beans, roasted soya nuts, and soyabean sprouts) with the dawn of civilization.

Soyabean was migrated from China to neighboring countries with the development of sea and land trades during 7th century. Introduction of soyabean to Indian subcontinent dates back to 1000 AD through silk route from northeastern India and Himalayan mountains. 

The black-seeded soyabean has been traditionally grown in North and northeastern regions of India and further spread to different parts of the country. This black-seeded soyabean, Kalitur, was the vehicle for soyabean revolution in India. The major initiative on soyabean cultivation was undertaken during 1963-64 by Govind Ballabh Pant University of Agriculture and Technology (GBPUAT), Pantnagar and Jawaharlal Nehru Krishi Vishwa Vidyalaya (JNKVV), Jabalpur in collaboration with University of Illinois, USA. The cultivation was further picked up after the researchers took advantage of yellow-seeded material to develop high-yielding varieties that suited Indian conditions.

Domestication and history

The origins of the soyabean plant are obscure, but many botanists believe it was first domesticated in central China as early as 7000 BCE. An ancient crop, the soyabean has been used in China, Japan, and Korea for thousands of years as a food and a component of medicines. Soyabeans were introduced into the United States in 1804 and became particularly important in the South and Midwest in the mid-20th century. Brazil and Argentina are also major producers.

Uses

The soyabean is one of the richest and cheapest sources of protein and is a staple in the diets of people and animals in numerous parts of the world. The seed contains 17 percent oil and 63 percent meal, 50 percent of which is protein. Because soyabeans contain no starch, they are a good source of protein for diabetics.
