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.

The invention relates to the technical field of medicament, in particular to inonotus obliquus extracellular and intracellular mixing crude polysaccharide with a function of strengthening immunity, which is extracted from a submerged fermentation product of medical fungus inonotus obliquus liquid. The method comprises the following steps: taking slant strain under an asepsis condition, and inoculating the slant strain into a plate filled with fresh comprehensive solid culture medium; pumping and filtering a secondary fermentation product through primary fermentation and secondary fermentationto obtain inonotus obliquus mycelium and fermentation supernatant; and preparing the inonotus obliquus extracellular and intracellular mixing crude polysaccharide through concentration and water extraction and alcohol precipitation. In vivo experiments prove that the inonotus obliquus extracellular and intracellular mixing crude polysaccharide can prolong the surviving time of mice hepatocellularcarcinoma H22 and S180 ascites tumor mice, and can obviously improve the thymus gland index and spleen index of the mice. Furthermore, the inonotus obliquus extracellular and intracellular mixing crude polysaccharide can obviously improve secretion of IL-2, TNF-alpha cell factors in the blood serum of the tumor-bearing mice, and can be used for preparing new immunity intensifying preparation. Theinvention opens up a new way for development and utilization of medical fungus resources.
