Abstract

The invention relates to a processing method for improving the enzymolysis efficiency of animal protein by utilizing a high energy electron beam irradiation technology, belonging to the technical fields of high energy electron radiation processing and livestock and poultry meat deep processing. The processing method comprises the following steps: thawing the animal protein (chicken and beef etc.), cleaning, grinding and adding water for enzyme hydrolysis after high energy electron beam irradiation, wherein the rate of hydrolysis can be increased by more than 2 times compared to the non irradiation treatment, which greatly shortens the time of hydrolysis. According to the invention, the high energy electron irradiation treatment is increased based on the conventional enzymatic hydrolysis method, which is characterized by loosening the dense organization structure of animal protein by utilizing the high energy electron beam irradiation, destroying a plurality of chemical bond of protein and the stability of the protein texture, helping the enzyme solution effectively penetrate, improving the enzymolysis efficiency and speed. Various microorganisms in the raw meat are effectively killed by the irradiation treatment and dispense with the complex enzymolysis process of hot sterilization and cooling for the raw meat, which ensure the health and safety in the production process, shorten the processing time and reduce the energy consumption during production.

Description

technical field [0001] The invention discloses a processing method for improving the enzymatic hydrolysis efficiency of animal protein by using high-energy electron beam irradiation technology, which relates to protein bio-enzyme degradation processing and belongs to the technical fields of high-energy electron radiation processing and deep processing of livestock and poultry meat. Background technique [0002] With the acceleration of people's life rhythm and the improvement of living standards, natural flavor and high-quality food have become the general pursuit of consumers. The animal protein produced by enzymatic hydrolysis can ensure the original umami taste of meat, and the addition of low-molecular-weight polypeptides and free amino acids can better highlight the umami taste and aroma of protein. After hydrolysis of animal protease, rich amino acids and peptides and other flavors are produced Precursor substances can be thermally reacted with sulfur-containing compou...
