The National Research and Promotion Center for Deep Processing of Soybeans adopts an independent innovation patented technology of “comprehensive utilization, continuous extraction of functional factors, reverse retention, and bio-enzymatic proteinâ€, with an annual output of about 20 million tons in China, and it can be considered as feed only at home and abroad. "High-temperature soybean meal" is used as raw material to successfully extract high-purity soybean oligopeptides, high-purity isoflavones, soybean complex factors, oligosaccharides, saponins, nucleic acids, protein concentrates, protein feeds from high (or low temperature) soybean meal. Dietary fiber powder 9 products.
Among them, high-purity soybean oligopeptides have been searched and searched at home and abroad and no similar technologies and products have been found. The acquisition of this patented technology for independent innovation will have a profound impact on China's health food and pharmaceutical industries.
For a long time, the extraction of high-purity oligopeptides has been a worldwide problem. The purity of the existing product protein does not exceed 90%, the content of soybean peptides is 55%-80%, and the color is yellowish or white, and there are odors, both at home and abroad. When soy protein is degraded from a macromolecule to a small molecule, the cleavage of the peptide tends to produce an unpleasant odor such as bitterness, astringency, etc., even in standards and writings.
According to Professor Li Ronghe, the director of the National Research and Promotion Center for Soybean Deep Processing Technology, and chief engineer Jiang Haokui, smells are due to other non-protein ingredients (such as saponins and isoflavones) that are left in the soybean peptide product, not the peptide itself. taste. The high-purity oligopeptides extracted from the National Research and Promotion Center for Soybean Deep Processing Technology have no odor, only slightly acidic odor of free amino acids, and are white in color and delicate in powder. They are completely soluble in water and are in a "true solution" state after adding water.
Protein is the first nutrient needed by the human body, accounting for 45% of the total dry matter of the human body and 70% of the total muscle mass. The body's cells, tissues, and organs are mainly composed of proteins, and the body's metabolism, immunity to disease, body fluids Balance, genetic information transmission and so on are all closely related to proteins. "Without protein, there is no life," so proteins are also called human "first nutrients." Absorption of protein is the key to life activities. The intake of protein in food needs to be digested by “enzymatic†digestion. It takes about 4 hours. The oligopeptides can be directly absorbed without being digested by the human body. The small molecule protein that can be quickly absorbed is an ideal protein source for sub-health populations, inpatients, and pre-students who need to quickly supplement protein nutrition and quickly restore physical fitness.
The Department of Animal Physiology and Pharmacology at Jilin Agricultural University used the “high-purity soybean oligopeptides†developed by the center as experimental drugs to carry out the “Pharmacokinetics Study Experiment†and the “Animal weight-bearing swimming testâ€. The results showed that animals were orally administered this product. After 5 minutes in the blood, peak plasma concentrations were reached in 10 minutes and the half-life was 12 hours. The results of a weight-bearing swimming test in mice showed that the mean swimming time of the administration group was 6.7 times that of the control group.
It is reported that the acquisition of this patent for invention has also found a fundamental solution to the “high-temperature desolved soybean meal†by substantially increasing the added value.
