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 are 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 "the valley of kidney". 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:
Soybeans not only refer to soybeans, but also include black beans and green beans. Soybean is full of nutrition and rich in soybean, of which the content of protein is 2 times higher than 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 ratio of amino acids is close to that needed by human body, so it is easy to be digested and absorbed. If soybean is eaten together with meat and eggs, its nutrition can be compared with that of eggs and milk, and even exceeds that of eggs and milk.
Soybean fat also has high nutritional value, which 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. Supplementing cellulose in a proper amount 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 has obvious functions of lowering plasma cholesterol, regulating gastrointestinal function and insulin level. Soybean meal is a by-product of soybean residue after extracting oil with low temperature (40-60℃), which is coarse powder. The antitrypsin, urease, hemagglutinin, saponin and goiter inducing factor of soybean will not be destroyed because it is not exposed to temperature.
Soybean meal is the most widely used and used plant raw material in protein.
