Abstract

The invention relates to a process for preparing corn peptides by taking corn starch sugar residues as raw materials. The process comprises the following steps of: crushing corn starch sugar residues, adding absolute ethyl alcohol to extract a yellow pigment, drying the materials subjected to complete pigment extraction, crushing and sieving, adding water, adjusting the pH value, and respectively adding alkaline protease and flavourzyme to hydrolyze; adjusting the pH value by using hydrochloric acid and adding active carbon to decolor and remove bitter; desalting the obtained feed liquid by using a membrane system, and freezing and drying in vacuum to prepare corn peptides powder. According to the process, the corn starch sugar residues are used as the materials to prepare the corn peptides, and the process is low in cost, material consumption and energy consumption, and is beneficial to the improvement of resource utilization of by-products.

Description

technical field

[0001] The invention relates to a method for preparing corn polypeptide by using corn starch sugar residue as raw material. Background technique

[0002] The proteins in corn are mainly zein-soluble protein (accounting for 55% of the total amount of zein), alkali-soluble protein (accounting for 39% of the total amount of zein), and water-soluble protein (accounting for 4% of the total amount of zein). %) and salt-soluble protein (accounting for 2% of the total corn protein). In the process of starch production, a large amount of protein in corn exists in the main by-product gluten water. After drying, corn gluten meal (CGM) containing about 60% protein can be obtained. Due to its poor water solubility, its application in the food industry is limited. Mainly used for feed. In recent years, with the advancement of technology, the application range of CGM in the food field has been gradually expanded. The main processing methods are extraction of corn yellow p...
