Production Methods and Multifunctional Applications of Soybean Dietary Fiber
1. Physiological Functions of Multifunctional Soybean Dietary Fiber Soybean dietary fiber mainly refers to the general term for those macromolecular carbohydrates that cannot be digested by human digestive enzymes, mainly including cellulose, pectin, xylan and mannose, etc. Although dietary fiber cannot provide the human body with any nutrients, it has important physiological functions for the human body. Dietary fiber has significant effects in lowering blood pressure and plasma cholesterol, and regulating gastrointestinal function, blood sugar and insulin levels. Multifunctional Soybean Fiber (MSF) is mainly composed of dietary fiber and protein, with contents of 67.98% (dry basis) and 19.75% respectively, making it a good protein-fiber additive. Studies have shown that adding a small amount of MSF has a good strengthening effect on medium-gluten or low-gluten flour; within a certain addition range, it can not only increase the dietary fiber and protein content of products, but is also very beneficial for improving the quality of products such as bread, noodles and biscuits. MSF may be the best-functioning of all dietary fibers, far beyond what other synthetic fibers (such as litesse, polydextrose) can match. Multifunctional soybean dietary fiber is a high-quality dietary fiber obtained from fresh okara as raw material through special heat treatment, and it has good effects in regulating blood sugar, lowering blood lipids and promoting defecation.

How can the new functional components of soybeans be developed and utilized?
China is the homeland of soybeans, and over the long course of history, "soybeans have nurtured the Chinese nation." Modern science has discovered that the functional components of soybeans that nurtured the Chinese nation are mainly found in soybean meal. High-temperature soybean meal is the highest-yield product of the soybean oil processing industry. Whether the effective components in high-temperature soybean meal can be extracted is key to revitalizing China's soybean oil processing industry. The National Soybean Deep Processing Technology Research and Promotion Center invented a process using high-temperature soybean meal as raw material to continuously extract high-purity soybean oligopeptides, soybean isoflavones,
