Method for preparing black fungus nutrient solution by utilizing food processing residues

Abstract

The invention provides a method for preparing black fungus nutrient solution by utilizing food processing residues. The method comprises the following steps: carrying out liquid culture and solid fermentation based on carrot residue as a main raw material for solid fermentation of black fungus and black fungus as a starting strain so as to obtain a large amount of fermented black fungus mycoplasm; then digesting fermented mycoplasm with a hot water digestion method so as to obtain extract rich in black fungus polysaccharide and amino acid, and preparing the extract into a concentrated liquid,wherein when the content of a soluble solid state material in the concentrated liquid is 6%, the content of polysaccharide can reach 3.3%, and the content of amino acid can reach 1150.596mg / 100mL; and finally, blending the concentrated liquid into a nutrient solution which is good in palatability. By application of the method, the food processing residues can be sufficiently utilized, natural resources can also protected, the problem that the wild black fungus resources are significantly in lack is relieved, and the black fungus nutrient solution can partially substitute for black fungus sporocarp for application.

Description

technical field [0001] The invention belongs to the field of edible fungus production and processing, and more specifically relates to a method for preparing black fungus nutrient solution from food processing residues. Background technique [0002] Black fungus (Auricularia auricula) belongs to the Phylum Fungi, Basidiomycetes, Order Auricularia, Auriculariaceae, and the genus Auricularia. It is a well-known medicinal and edible fungus. It is a large fungus composed of mycelium and fruiting bodies. Its main active ingredient black fungus polysaccharide has anti-tumor, anti-thrombosis, anti-aging, hypoglycemic, hypolipidemic, immune-regulating and other functions. Mycelium is the vegetative organ of black fungus, which is equivalent to the roots, stems and leaves of higher green plants, and is the main body of black fungus. The fruiting body of black fungus, also known as basidiocarp, is the part we cook and eat. [0003] "Compendium of Materia Medica" records that black f...

AI Technical Summary

Problems solved by technology

[0005] At present, in the field of black fungus liquid fermentation technology, there are high cost of raw materials, low yield of fermentation mycelia and crude polysaccharide content of mycelium, and no effective fermentation products. Issues such as extraction and utilization

At present, there is no report on the use of food processing residues to make black fungus nutrient solution through black fungus solid-state fermentation culture
