Method for extracting active peptides from Qinzhou yellow pond turtle

Abstract

The invention discloses a method for extracting active peptides from a Qinzhou yellow pond turtle. The method comprises the following steps of raw material treatment, hydrolysis, enzymolysis, freezing, melting, concentrating and spray drying to obtain a finished product. Compared with the traditional seed solution shaking table activation, inoculation, fermentation liquid culture and wall breaking technologies, the method has the advantage that the time is greatly shortened.

Description

technical field [0001] The invention relates to a preparation method of an active peptide, in particular to a method for extracting the active peptide from Qinzhou stone money turtle. Background technique [0002] Stone money turtle, also known as stone turtle, belongs to the genus Pseudowater turtle, which belongs to amphibious animals, and has extremely high medicinal value, edible value, ornamental value and humanistic value. Everyone knows that turtles are long-lived. Turtles have a lifespan of hundreds of years. As the saying goes, "thousand-year bastards, ten-thousand-year turtles", tortoises not only have strong vitality, but also have polypeptide longevity factors in their bodies. Edible and medicinal turtle meat can prolong life, and the polypeptide longevity factor in the longevity turtle can be fully absorbed by the human body. Many active substances in the human body exist in the form of peptides. Studies have found that more than 70% of the dry weight of the h...

The fermentation broth was cultured with intermittent stirring at 15-40°C for 1-4 days, then the fermentation broth was broken in a boiling water bath for 10-40 minutes, the supernatant was collected by centrifugation, concentrated and dried to obtain the skin longevity factor peptide with high protein content and good functional activity. , but the time is long and the yield is low
