Problems solved by technology

Although polypeptide manufacturers have adopted certain debittering and deodorizing processes in the preparation of polypeptides, because the enzymes used for proteolysis are relatively single, only a few trypsin and alkaline protease are used in actual production. , neutral protease, papain, etc., no ideal enzyme can be found, which can ensure that the hydrolyzate has a certain degree of hydrolysis without bitter taste
In addition, the lack of systematic and in-depth theoretical research on protein enzymatic hydrolysis mechanism and process control makes the control of hydrolysis process lack certain theoretical guidance, resulting in the flavor of hydrolyzate, especially the problem of bitter odor has not been fundamentally resolved, resulting in soybean Peptide powder raw materials are extremely unstable, even different batches of soybean peptide powder produced by the same manufacturer have uneven bitterness and odor
Moreover, when the polypeptide is added to a certain amount, the bad flavor and color become more and more obvious, which greatly limits the application of soybean polypeptide in beverages and other foods

Description

technical field [0001] The invention relates to a preparation method of soybean polypeptide beverage. Background technique [0002] Soybean peptide powder is produced from soybean, soybean meal or soybean protein by enzymatic hydrolysis or microbial fermentation. The main ingredient is a small peptide with a molecular weight distribution below 10,000 Dalton. The appearance of the product is white or light yellow powder. Recent studies have shown that protein is not completely absorbed in the form of amino acids after digestion in the body, but is directly absorbed in the form of peptides (especially dipeptides and tripeptides). According to data reports, small molecule soybean polypeptide not only has good solubility, low viscosity, and anti-gel formation, but also absorbs quickly in the body and has a high utilization rate. [0003] However, in the process of enzymatically hydrolyzing soybean protein into low-molecular-weight peptides and peptones, many bad flavors, especi...
