What is Soy Dietary Fiber?

Soy Dietary Fiber Powder

Soybean dietary fiber mainly refers to the general term for high-molecular sugars in soybeans that cannot be digested by human digestive enzymes. It mainly includes cellulose, pectin, xylan, mannose, etc. Although dietary fiber cannot provide any nutrients for the human body, it can safely regulate the blood sugar level of the human body, prevent constipation, and increase satiety. At the same time, it has the physiological functions of preventing obesity, promoting the proliferation of bifidobacteria and aerobic bacteria, enhancing the function of macrophages, and improving disease resistance. Therefore, dietary fiber is recognized as the “seventh largest nutrient” by the medical and nutritional circles. In addition, soybean dietary fiber also has the characteristics of rich nutrition, unique flavor, safe and convenient consumption, etc., and is the best among dietary fibers.

As a by-product in the production of soybean products, bean dregs have not been well utilized as feed for a long time. With the development of food science, people have a new understanding of it from the perspective of nutrition. Okara (dry basis) contains 20% protein, 53.3% carbohydrates, and 3.3% fat. In addition, it also contains minerals such as calcium and iron. Using soybean dregs to produce dietary fiber is a new way for comprehensive utilization of soybeans.

The term dietary fiber did not appear in nutrition before 1970. According to the definition of “GBZ 21922-2008 Basic Terms of Food Nutrients”, dietary fiber refers to the naturally occurring, extracted or synthetic fibers in plants. Polymers of carbohydrates, whose degree of polymerization is DP ≥ 3, cannot be digested and absorbed by the small intestine of the human body, and have health significance for the human body. Including cellulose, hemicellulose, pectin, inulin and other dietary fiber monomer components. Dietary fiber is essential to a healthy diet. Fiber plays an important role in maintaining a healthy digestive system. Adequate fiber intake can also prevent cardiovascular disease, cancer, diabetes and other diseases. Fiber can clean the digestive wall and enhance digestive function. Fiber can also dilute and accelerate the removal of carcinogens and toxic substances in food, protect the fragile digestive tract and prevent colon cancer. Fiber slows down digestion and excretes cholesterol the fastest, so blood sugar and cholesterol in the blood can be controlled at optimal levels.

Dietary fiber is mainly polysaccharides that cannot be utilized by the human body, that is, polysaccharides that cannot be digested by digestive enzymes in the human gastrointestinal tract and are not absorbed and utilized by the human body. This type of polysaccharide mainly comes from complex carbohydrates in plant cell walls, and can also be called non-starch polysaccharides, that is, polysaccharides other than α-glucan.

Nutritional value:

Physiological functions of soybean dietary fiber Soybean dietary fiber obtained through microbial degradation has no nutrients such as protein, vitamins, and fat, but it has other physiologically active functions for the human body. Enhance the immune function of the human body Many soluble dietary fibers — polysaccharides can significantly increase the rate of macrophages and the phagocytic index of macrophages in the body, and can stimulate the production of antibodies, thereby enhancing the immune function of the human body. Dietary fiber can also reduce certain hormones in the body and have the effect of preventing and treating breast cancer, uterine cancer and prostate cancer. Slow down the degeneration of adult teeth. The application of soybean dietary fiber can effectively maintain the mechanism of our health due to the characteristics of dietary fiber itself and its physiological effects on the human body.
