The total protein content of soy products is higher than that of meat
1, soybean protein contains 35% to 40%, protein contains a variety of essential amino acids and non-essential amino acids, except methionine, cystine and other thionine-containing small foot, other amino acids and animal amino acids, the total protein content is higher than meat.
2, contain fat 15%-35%, 85% of which is unsaturated fatty acid, occidoleic acid up to 50%, oleic acid more than 26%.
3, containing carbohydrate 25%-35%. It is mainly starch and cane sugar, which can not be absorbed by human body. Half of the carbohydrate in soybean is the sugar which can not be absorbed by human body.
4, soybean is rich in iron and vitamin B1, B2 and vitamin A, vitamin D, phosphorus, iron, selenium and other trace elements.
5. Soybean contains saponins and soybean isoflavones, which have antioxidant, hylipid-lowering, anti-hemolysis, anti-fungal, anti-tumor and estrogen-like effects.
Anti-nutrient factors of soybean
1. The protein enzymes contained in the digestive tract inhibit trypsin, pepsin and chymoprotein, which have a negative effect on human or animal growth due to the inhibitory effect on the digestive system.
2. Plant red fine lectin (PHA) has the effect of agglutinating human and animal red blood cells.
3. Containing oligosaccharides, hydrothreose and gossylose cannot be digested and absorbed by intestinal tract, and are fermented by intestinal microorganisms to produce gas, which is one of the causes of intestinal flatulence.
