Preparation process of channel catfish roe extract

Abstract

The invention provides a preparation technology of channel catfish roe extract. The preparation technology comprises the following steps that channel catfish roes are subjected to fishy smell removal, decoloration and impurity removal treatment through a three-removal treatment solution; rinsing the ietalurus punetaus roes subjected to three-stage removal treatment to obtain clean ietalurus punetaus roes without mucus; the method comprises the following steps: grinding rinsed clean channel catfish roes, adding sterile pure water, adding channel catfish roe hydrolysis compound enzyme, carrying out enzyme hydrolysis, and filtering to obtain an enzymatic hydrolysate; extracting the dissolved enzymatic hydrolysate, performing centrifugal treatment, and taking upper suspension slurry and supernate; freezing and drying to obtain a roe extract; the channel catfish egg extract prepared by the preparation method disclosed by the invention can retain the main nutritional ingredients of channel catfish eggs: yolk proplasm, vitelline lipoprotein peptide, phosvitin peptide, vitelline globulin peptide, five nucleic acids, 18 essential chloro acids, omega-3 and omega-6 fatty acids, multivitamins, minerals, trace elements and the like.

Description

technical field [0001] The invention relates to the technical field of biological enzyme hydrolysis cosmetics, in particular to a preparation process of channel catfish roe extract. Background technique [0002] Channel catfish roe contains nutrients needed for the development of fish embryos and larvae, and has a variety of nutritional elements for biological development. The nutrients that channel catfish eggs should have: catfish egg yolk precursor, yolk phospholipid protein peptide, phosvitin peptide, yolk globulin peptide, 5 kinds of nucleic acids, 18 kinds of essential amino acids, omega-3 and omega- 6 fatty acids, multi-vitamins, minerals, and trace elements are the nutrients needed to nurture life, so they can effectively moisturize and nourish the skin, making the skin delicate and smooth. It is a high-quality low-molecular biological raw material resource to be developed. [0003] There are more than 100 species of Siluriformes in the world, all of which are scale...

AI Technical Summary

Problems solved by technology

[0003] There are more than 100 species of Siluriformes in the world, all of which are scaleless economic fishes. Channel catfish is omnivorous, carnivorous, fast growing, wide adaptable, and rich in meat quality. Thorns are easy to process into various aquatic products, but catfish roe is treated as leftovers after processing or low-end aquatic products, which is easy to cause waste of resources and environmental pollution. At present, no processing enterprises in our country carry out intensive processing and utilization of catfish roe in the process of processing , all of which are treated as the leftovers of aquatic product processing are more likely to cause environmental pollution and waste of high-quality biological resources

[0004] The current research is of great significance for the fish egg extract to only stay in the single-component extraction stage, and to find a preparation method that can not only retain the main nutritional components but also obtain low-molecular-weight channel catfish egg extract, such as the currently disclosed fish egg The preparation method of the extract only extracts protein peptides, and other nutrients are wasted, and the nutrients needed for fish eggs to breed life are not really preserved
