The present application relates to the technical field of biological medicine, and particularly relates to a method for extracting and determining selenoprotein from selenium-rich lycoperdon pygmaeum mycelium, wherein the lycoperdon pygmaeum mycelium fermented by a 20L biological culture tank is dried in a vacuum drying box, ground into standard powder through a 100-mesh sieve, 0.5g of the standard powder is weighed, a 0.05mol / L NaOH solution is added, ultrasonic-assisted extraction is performed, then centrifugation is performed at a speed of 3000r / min for 15min, the supernatant is adjusted to an isoelectric point, centrifugation is performed again to obtain a protein precipitate, and finally the protein precipitate is dried in a freeze dryer to obtain a protein sample. The present application is dedicated to using the selenium-rich lycoperdon pygmaeum mycelium as raw material, adopting ultrasonic extraction, optimally optimizing the extraction process of selenoprotein, quantitatively analyzing the selenium content in the protein, detecting the change of the type and quantity of amino acids before and after selenium enrichment through a thin layer chromatography test, and understanding the influence of selenium on the amino acids in the lycoperdon pygmaeum mycelium.

The invention discloses bionic shark fin flavor essence, a probiotic microcapsule, a preparation process of the bionic shark fin flavor essence and the probiotic microcapsule and an instant seasoning. The bionic shark fin flavor essence is prepared from the following components in percentage by weight: 0.5%-1.5% of L-alanine, 0.3%-1.0% of glycine, 0.05%-0.4% of disodium 5 '-inosinate, 0.05%-0.4% of disodium 5'-guanylate and 0.1%-0.8% of sodium succinate. 1%-5% of yeast extract, 2%-8% of mushroom mycelium fermentation liquor, 0.05%-0.3% of ginger oleoresin and 0.03%-0.25% of garlic oleoresin; 20%-55% of propylene glycol and 5%-15% of sorbitol; 0.2%-3% of probiotic microcapsules subjected to embedding treatment; and the balance of deionized water. According to the bionic shark fin flavor essence provided by the invention, through an elaborately designed plant base and fermentation source formula, the dependence of the traditional shark fin flavor on seafood extracts is completely avoided, the seafood allergen risk is completely eradicated, and the consumption requirements of special crowds are met.

The invention relates to the technical field of cosmetic raw material preparation, in particular to a preparation method of mushroom mycelium fermentation liquor with a skin barrier repairing function, and solves the problems of unstable metabolites and poor batch repeatability caused by unknown mushroom strain sources and random culture parameters in the prior art. The preparation method of the shiitake mushroom mycelium fermentation liquor with the skin barrier repairing function comprises the steps that shiitake mushroom strains are inoculated into a slant culture medium and cultured for 7-10 days at the temperature of 20-25 DEG C, the lawn is obtained, and the slant culture medium is prepared from 18-24 g / L of potato glucose water, 15-20 g / L of agar powder and the balance water. By optimizing a culture medium formula and key process parameters, stable components, high activity and good batch consistency of the fermentation liquor are realized, and the problem of quality fluctuation caused by strain disorder and extensive process is effectively solved.
