Hericium erinaceus dietary fiber as well as preparation method and application thereof

Abstract

The invention discloses hericium erinaceus dietary fiber as well as a preparation method and application thereof, and belongs to the technical field of food processing. The preparation method comprises the following steps: washing hericium erinaceus residues after polysaccharide and protein extraction with water, crushing and drying for later use; adding distilled water according to a material-liquid ratio of 1 g: (30-40) mL, and adding alkaline protease for enzymolysis for 25-30 min; adjusting a pH value to 5-6, adding cellulase for enzymolysis, carrying out microwave ultrasonic treatment while carrying out enzymolysis, and carrying out enzyme deactivation in a boiling water bath for 10-15 min; and adding an ethanol solution, and carrying out suction filtration, washing and drying to obtain the hericium erinaceus dietary fiber. The hericium erinaceus dietary fiber has a clustered structure with a damaged surface structure, can bind and destroy fat emulsions, improve excretion of bile acids in feces, improve metabolism of bile acids, and delay diffusion and absorption of lipids and cholesterol in the small intestine.

Description

Technical field[0001]The present invention relates to the field of food processing, and more particularly to a monkey head mushroom meal fiber, preparation method and its application thereof.Background technique[0002]Muskey head mushroom is also known as monkey, monkey mushroom, is a precious medicinal food and fungus in my country. Chinese medicine believes that the mushrooms are plain, favorable, hard-to-digest, digestion, nourishing the body. In recent years, research on monkey head mushroom is mainly concentrated in polysaccharides, protein, etc., studies have shown that monkey head mushroom polysaccharide has activity, anti-oxidation, hypophache, etc. The relative molecular mass of the immunomodulatory protein is 10-14 kDa. However, the water-soluble polysaccharide is extracted, and a large amount of monkey head mushroom is produced. Its main components include dietary fibers (DF), minerals, small proteins and pigments, so prepared high value and high quality from monkey head m...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to provide a high-quality dietary fiber of Hericium erinaceus and its preparation method, so as to solve the problems of low utilization rate of Hericium erinaceus resources and serious waste of raw materials in the current polysaccharide and protein extraction process of Hericium erinaceus, and improve the quality of Hericium erinaceus. The utilization efficiency of this cherished resource creates greater economic and social benefits
