Culture material for increasing amino acid content of Hericium erinaceus, preparation method and application

Abstract

The invention belongs to the technical field of Hericium erinaceus culture materials, and discloses a culture material for increasing the amino acid content of Hericium erinaceus, a preparation methodand an application. A milkvetch root medicinal residue and a swollen bamboo powder are main base materials of the Hericium erinaceus culture material. The culture material of the invention has significant production effects, shortens a production period of Hericium erinaceus to 25 days, the produced Hericium erinaceus hypha is white, has no bitter taste, and has high yield, and at the same time the content of amino acids and polyphenols is greatly increased. The milkvetch root medicinal residue and bamboo powder softening swelling technology is developed, a formula of the culture material anda culture process are innovated, and the culture material is used to produce Hericium erinaceus. The Hericium erinaceus mycelia cultured in the invention is white, and oval in shape, a length of fungus thorns is 0.5-0.8 cm, a weight of a single mushroom is 420-460 g, the crude protein content of Hericium erinaceus is 28%-32%, the free amino acid content is 2.23%-3.02%, and the essential amino acids account for 40% or more of the total free amino acids.

Description

technical field [0001] The invention belongs to the technical field of Hericium erinaceus culture materials, and in particular relates to a culture material for increasing the amino acid content of Hericium erinaceus, a preparation method and an application. Background technique [0002] Hericium erinaceus (Hericium erinaceus), also known as Hericium erinaceus, Hedgehog, and Shanfu, is not only rich in nutrition, but also has good medicinal value and delicious taste. It is a famous edible and medicinal fungus. A large number of studies have shown that Hericium erinaceus not only has a special effect on digestive system diseases, but also has the effects of enhancing immunity, anti-tumor, anti-aging, lowering blood sugar, protecting nerves and antibacterial effects. The nutrients of Hericium erinaceus include protein, fat, cellulose, polysaccharides, trace elements and 8 kinds of essential amino acids. Wild Hericium erinaceus has limited natural resources and is currently ma...

AI Technical Summary

Problems solved by technology

[0004] (1) The production cost of Hericium erinaceus compost is high and the economic benefit is low

[0005] (2) Low amino acid content and poor quality in cultivated Hericium erinaceus

So far, no edible fungus culture material with low cost, sufficient supply, and quality improvement of Hericium erinaceus has been found. The present invention proposes a new type of culture material based on bamboo powder-astragalus dregs through a large number of screening and fixing techniques. The material formula solves the above problems and is conducive to the healthy development of Hericium erinaceus industry
