Use of sea collagen peptide in preparing medicine or food capable of improving senility memory function

Abstract

The invention relates to a marine collagen peptide product and application of the marine collagen peptide product in preparing a medicine or food for improving senile memory. Marine collagen peptide is a group of oligopeptide mixtures with low molecular weight produced by hydrolyzing fishskins of marine fishes (salmon, tilapia, and the like). 70 to 80 percent of molecular weight of oligopeptide is distributed between 200 and 1000Da. The marine collagen peptide product has the characteristics of easy absorption, quick absorption, low viscosity, good water solubility, and the like. An experiment proves that a senile mouse is provided with the marine collagen peptide so as to can remarkably improve the abilities of passive avoidance, active avoidance and spatial memory exploration of the senile mouse, and the marine collagen peptide product has the efficacy of improving the senile memory.

Description

technical field [0001] The invention relates to a marine bioactive oligopeptide and its new application, in particular to the application of the marine collagen peptide extracted from marine fish in medicine or food for improving memory function of the elderly. It belongs to the field of medicine and food health care. Background technique [0002] Population aging is one of the major social problems faced by mankind in the 21st century, and it will definitely constitute the main feature of the development of human society in the 21st century. With the aging of the population, brain degenerative diseases and cognitive decline will become the "first killer" of human beings, especially the elderly. According to reports, about 50% of middle-aged and elderly people complain of memory loss; the abnormal memory rate of objective memory examination based on different test methods can reach 32% to 78%. At present, there are about 20 million elderly patients with memory impairment i...

AI Technical Summary

Problems solved by technology

[0008] At present, there are few studies on the effect of marine bioactive peptides on improving the memory function of the elderly. If the development of health food can improve the memory function of the elderly and prevent the occurrence of senile dementia, it is economical and practical, and will bring great benefits to my country's health care industry. big prospects
