Problems solved by technology

However, the existing technology for preparing high F value corn oligopeptides has problems such as high cost, complex process, degree of automation, low product yield, purity and hepatoprotective activity, and high bitterness value.
As a result, the current high F value corn oligopeptides are limited to exploratory experimental research in the laboratory, and the industrial production of high F value corn oligopeptides has not yet been realized.

Abstract

The invention discloses an industrial production method of high-F-value corn oligopeptide with alcohol dispelling and liver protection activities. The production method comprises the following steps: carrying out high-speed shearing emulsification on corn gluten meal (CGM), carrying out enzymolysis by combining basic protein with compound flavored proteinase, carrying out enzyme deactivation and frame filtering, carrying out activated carbon adsorption to remove bitterness, colors and aromatic amino acid, carrying out separation and purification by virtue of ultrafiltration equipment, carrying out desalination by virtue of nanofiltration, and carrying out spray drying, so as to obtain the high-F-value corn oligopeptide. According to the high-F-value corn oligopeptide produced by virtue of the production method, the fatty degeneration index of liver cells of mice with alcoholic hepatic injury can be decreased, meanwhile, the contents of triglyceride (TG) and malondialdehyde (MDA) in the livers can be reduced, and the content of reduced glutathione (GSH) can be increased; and a result shows that the high-F-value corn oligopeptide produced by virtue of the production method has the effect of preventing the alcoholic hepatic injury of the mice.

Description

technical field [0001] The invention relates to an industrial production method of a high F-value corn oligopeptide with the activity of sobering up and protecting the liver, and belongs to the field of deep processing of vegetable protein. Background technique [0002] High F value corn oligopeptide is a mixed small peptide system composed of 2-6 amino acid residues with a molecular weight below 1000Da prepared from corn yellow powder (CGM), and its notable feature is the molar ratio of branched chain amino acids to aromatic amino acids (F value) is relatively high, generally greater than 20. High F value corn oligopeptides have various physiological functions such as anti-fatigue, supplementing essential amino acids for human body, promoting alcohol metabolism, protecting liver and liver, and improving protein nutrition status of postoperative and bedridden patients. my country is rich in CGM powder resources, with an annual output of more than 300,000 tons, which has not...
