Application and preparation method of roe polypeptide

Abstract

The invention relates to the field of antitumor food, in particular to application and a preparation method of roe polypeptide. The application refers to application of the roe polypeptide in preparation of antitumor and tumor prevention and treatment food. The preparation method of the roe polypeptide comprises the steps as follows: 1) collection of roe cells; 2) thorough cleaning, cell homogenization, freezing and thawing, sedimentation, taking of supernatant, interception and impurity removal and detection treatment of the roe cells; 3) preparation of a roe polypeptide stock solution; and 4) preparation of roe polypeptide powder, mother liquor or solution. Roes play antitumor and anticancer functions by the inhibition effect on melanoma and tumor. Fish byproducts are efficiently utilized in medicines and food and create social benefits for economic development. Compared with a traditional antitumor drug preparation, as bioactive peptides naturally exist in the roe polypeptide stocksolution obtained by roe extraction, the components of the roe polypeptide have certain safety, as an antitumor drug or health food, the roe polypeptide has safety and reliability higher than that oftraditional antitumor drug preparation.

Description

technical field [0001] The invention relates to the field of an anti-tumor food, in particular to the use of caviar polypeptide and its preparation method. Background technique [0002] In recent years, anti-tumor drugs have become a topic of concern to modern people, and their research and development work has also attracted public attention. As we all know, malignant tumors seriously threaten human life, health and safety, but most of the current anti-tumor drugs cannot completely resist viruses. , and there are disadvantages such as low selectivity, strong toxic and side effects, and easy drug resistance. Therefore, the research and development of new anti-tumor drugs has always been the focus of research and development in the biological field. At present, research has found that antimicrobial peptides have broad-spectrum antibacterial activity and can quickly kill targets, and many of them are pure natural peptides, making them quickly become potential therapeutic drugs...
