The developed agricultural background makes cereal and soybean food the main food of the eastern farming people, and soybean food represented by tofu and soybean milk can be said to be one of the most outstanding representatives in the human diet spectrum.
Soybean generally refers to its seeds. According to the color and grain shape of seed coat, soybeans can be divided into five categories: yellow soybeans, green soybeans, black soybeans, other soybeans and feed beans.
Soybean is the most widely planted variety in soybean. Soybean is most commonly used to make various bean products, brew soy sauce and extract protein. Bean dregs or ground into coarse powder are also commonly used in livestock feed.
Soybean is called "Valley of Kidney". Traditional Chinese medicine believes that it has the effects of tonifying kidney, strengthening body, detoxifying and moistening skin, and has a good therapeutic effect on kidney deficiency and edema.
Extended data:
Soybean not only refers to soybeans, but also includes black beans and mung beans. Soybean is rich in nutrition, and the content of protein is twice that of pork and 2.5 times that of eggs. The content of protein is not only high, but also of good quality.
The amino acid composition of soybean protein is similar to that of animal protein, in which the proportion of amino acids is close to the needs of human body and easy to digest and absorb. If soybean is eaten with meat and eggs, its nutrition can be comparable to that of eggs and milk, even more than that of eggs and milk.
Soybean fat also has high nutritional value, contains a lot of unsaturated fatty acids, and is easily digested and absorbed by human body. Moreover, soybean fat can prevent the absorption of cholesterol, so soybean is an ideal nutrient for patients with arteriosclerosis.
Dietary fiber in bean dregs plays an important role in promoting good digestion and excreting solid waste. Appropriate cellulose supplementation can increase and soften the food in the intestine, promote intestinal peristalsis, thus speeding up defecation, preventing constipation and reducing the risk of intestinal cancer.
At the same time, dietary fiber can obviously reduce plasma cholesterol, regulate gastrointestinal function and insulin level. Soybean meal is a by-product of soybean meal oil extraction at low temperature (40-60℃), which is coarse powder. Soybean's antitrypsin, urease, hemagglutinin, saponin and goiter inducing factor will not be destroyed because they are not exposed to temperature.
Soybean meal is the most widely used and versatile plant material in protein.
