Embodiment 1

[0025] A kind of production method with selenium-enriched Cordyceps militaris powder, its main process step comprises:

[0026] Step 1, preparation of the mother species of Cordyceps militaris;

[0027] The Cordyceps militaris strain CICC14013 was purchased from China Industrial Microorganism Culture Collection Management Center and activated with PDA medium. The formula of PDA medium for activation is as follows: 200g of peeled potatoes (boiled juice), 20g of glucose, 18g of agar, 1000ml of water, and the pH is natural. Incubate at 18°C ​​in shade.

[0028] Dig mycelium from the edge of the activated dominant colony and inoculate it into the acclimatization medium. Use slant medium for domestication, slant medium: organic selenium-enriched brown rice powder, potted rice chestnut powder, selenium-enriched silkworm chrysalis powder, 10g each, glucose 5g, agar 18g, water 1000ml, high pressure steam sterilization, pH nature. Incubate at 18°C ​​in shade.

Abstract

The invention discloses a preparation method of selenium-enriched cordyceps militaris powder. The preparation method comprises the following steps of step (1) preparing cordyceps militaris mother strains; step (2) preparing cordyceps militaris liquid state fermentation strains; step (3) preparing cordyceps militaris solid fermentation culture mediums; step (4) culturing cordyceps militaris and dissolving mycelia; and step (5) preparing the selenium-enriched cordyceps militaris powder. Products can be used for safe addition of food organic selenium. The preparation method disclosed by the invention has the advantages that production of the selenium-enriched cordyceps militaris powder is wholly based on organic selenium transformation, so that absolute safety of a selenium source is guaranteed; the products not only contain rich organic selenium, but also contain functional components of cordyceps militaris, and dietary fibers of various oligosaccharide and polypeptide obtained through enzymatic degradation; and the production efficiency of selenium-enriched edible mushroom powder is higher than that of a present general technique.

Description

technical field [0001] The invention belongs to the technical field of intensive processing of agricultural products, and relates to a preparation method of selenium-enriched Cordyceps militaris powder. Background technique [0002] Selenium is very beneficial to human health, but the utilization rate of inorganic selenium is low and its toxicity is strong. Both plants and microorganisms have the ability to absorb and convert inorganic selenium into organic selenium. The main residues of organic selenium are known to be selenoamino acids and proteins with selenoamino acid residues, and some biological polysaccharides contain Sulphate ester structure can also undergo selenization reaction. In addition, liliaceous plants contain non-protein sulfur-containing amino acids, which can also undergo selenization reaction, which has also received attention. [0003] Utilizing the selenium-rich characteristics of some edible fungi with significant physiological functions to enrich se...
