Preparation method of hericium erinaceus polysaccharide protein extract

Abstract

The invention discloses a preparation method of a hericium erinaceus polysaccharide protein extract. The preparation method comprises the following steps: S1, obtaining hericium erinaceus powder; s2,performing ultrasonic wall breaking, and soaking in an extracting solution; s3, introducing an inert gas until the pressure is 4000-5500 kpa, and rapidly recovering to normal atmospheric pressure to obtain hericium erinaceus cell suspension; and s4, conducting centrifugal separation, and precipitating supernate through ethyl alcohol to obtain the hericium erinaceus polysaccharide protein extract;the hericium erinaceus polysaccharide protein is extracted evenly and thoroughly, the extraction speed is high, operation is easy and convenient, the structural integrity of the polysaccharide proteinis protected, the extraction rate is high, pure physical extraction is achieved, and the hericium erinaceus polysaccharide protein extract is non-toxic, harmless and low in cost.

Description

technical field [0001] The invention relates to the field of Hericium erinaceus, in particular to a preparation method of a polysaccharide protein extract of Hericium erinaceus. Background technique [0002] Hericium erinaceus polysaccharide protein has good health care functions, such as treating gastritis and gastric ulcer, lowering blood sugar, anti-radiation and improving immunity, scavenging free radicals, anti-aging, protecting liver and liver, strengthening stomach and spleen, etc. Function, can induce tumor cell apoptosis, strongly inhibit the activity of tumor cell telomerase, can promote the generation of hematopoietic stem cells and progenitor cells in mice, and improve their hematopoietic function. It is a good antioxidant and has certain antioxidant properties. Features. [0003] Therefore, it is of great significance to obtain complete and high-purity Hericium erinaceus polysaccharide protein. [0004] In the prior art, there are multiple methods for extracti...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there are multiple methods for extracting Hericium erinaceus polysaccharides, such as utilizing heat treatment to destroy the cell structure, promoting the release and transfer of intracellular substances, thereby extracting polysaccharides, but the extraction time is long and the extraction rate is low; while acid extraction, Alkaline extraction is a method of extracting polysaccharides by chemically destroying the cell structure. While destroying the cell wall and other structures, it will also destroy the structure of polysaccharides, so it is not commonly used; with the promotion of enzyme preparations, enzymatic hydrolysis is gradually applied to the extraction of polysaccharides , mainly using the enzymatic hydrolysis of pectinase to achieve the purpose of destroying the cell structure, but it is limited due to its high cost
