Needle mushroom fresh-keeping agent and preparation method thereof

Abstract

The invention belongs to the field of edible fungus fresh keeping, and particularly relates to a needle mushroom fresh-keeping agent and a preparation method thereof. The needle mushroom fresh-keepingagent is prepared from the following raw materials in parts by weight: 3 to 6 parts of folium artemisiae argyi, 10 to 15 parts of yellow cinnamon leaves, 3 to 6 parts of lotus leaves, 6 to 10 parts of fructus chebulae, 3 to 6 parts of rhizoma polygoni cuspidati, 3 to 6 parts of radix paeoniae rubra, 2 to 4 parts of rhizoma anemarrhenae, 3 to 6 parts of green tea, 6 to 10 parts of radix arnebiae seu lithospermi, 3 to 6 parts of herba andrographitis, 8 to 12 parts of Ilex pur-purea buds, 3 to 6 parts of herba arabidopsis thalianae, and 2 to 4 parts of pears. The raw materials are classified into three types according to the effect of raw materials and are extracted by separately utilizing a water decoction extraction method, a methanol extraction method, and an ethanol reflux method, and then the obtained extraction solutions are mixed and fermented, thus obtaining the needle mushroom fresh-keeping agent. By adopting the needle mushroom fresh-keeping agent provided by the invention, the growth proliferation of microorganisms can be inhibited, the breathing and metabolism effect of the needle mushrooms can be alleviated, the needle mushrooms can be effectively kept fresh, and the fresh-keeping period can be 40 days or more; and moreover, the needle mushroom fresh-keeping agent is wide in raw material source, simple in preparation method and low in cost.

Description

technical field [0001] The invention belongs to the field of fresh-keeping edible fungi, in particular to a fresh-keeping agent for Flammulina velutipes and a preparation method thereof Background technique [0002] Flammulina velutipes, also known as hairy-stalked money fungus, structure fungus, port mushroom, winter mushroom, golden mushroom, intellectual mushroom, belongs to Basidiomycota, Agaricomycetes, and is a kind of wood saprophytic fungus. Flammulina velutipes does not contain chlorophyll, does not have photosynthesis, cannot produce carbohydrates, but can grow in a dark environment completely, must absorb ready-made organic substances from the medium, such as carbohydrates, protein and fat degradation products, and is saprotrophic , is a heterotrophic organism. Flammulina velutipes is rich in compounds such as protein, amino acid, mineral matter, carotene, etc. It has high medicinal value and therapeutic effect, and is a good health care effect.

Problems solved by technology

[0003] After harvesting, Flammulina velutipes has soft tissues, high water content, and strong breathing. Under the action of microorganisms and enzymes, it is easy to lose its original color, aroma, and taste, and it will open umbrellas, brown, and taste, which seriously affects its products. Quality and Shelf Life

The traditional preservation of Flammulina velutipes uses sodium metabisulfite for color protection and potassium sorbate for antisepsis. Although it has a good effect, it has toxic side effects and carcinogenic effects on human health.

In addition, preservatives such as Vc used for color protection and browning inhibition are poor in effect and unstable.

Therefore, people have developed broad-spectrum, safe, cheap natural antistaling agent, and these natural antistaling agents are mostly with antibacterial Chinese medicine as raw material, though can effectively suppress the reproduction of microorganism in the Flammulina velutipes, very little to the enzyme action in Flammulina velutipes
