Abstract

The invention discloses a coating preservation method for agaricus bisporus. The method includes the steps that agaricus bisporus sporocarp is placed into a silicate solution with the concentration of 0.1-0.6 mmol/L to be soaked for 10-30 min, and then conventional coating preservation is carried out. Silicate impregnation and conventional coating are combined, transpiration of agaricus bisporus can be reduced greatly, water loss of agaricus bisporus is delayed, the aerobic respiration intensity of agaricus bisporus can be reduced to the minimum without causing anaerobic respiration, and consumption of nutrient components is reduced; as the strength of agaricus bisporus cell walls is enhanced, the resistance ability of agaricus bisporus to the outside is enhanced, agaricus bisporus processed through the preservation method can be stored and preserved under the constant temperature condition, and the preservation period can reach 10 d or more.

Description

The coating-film fresh-keeping method of Agaricus bisporuss
Technical field
The present invention relates to a kind of edible mushroom preservation method is and in particular to a kind of coating-film fresh-keeping method of Agaricus bisporuss.
Background technology
Agaricus bisporuss (tricholoma lobayense heim) also known as " Tricholoma lobayense ", belong to the sub- double spore mushrooms of basidiomycetes Also known as white mushroom, mushroom, mushroom, European and American countries operator is often referred to as common to plant mushroom (agaricus bisporus) Training mushroom or button mushroom.Agaricus bisporuss are the mushrooms of worldwide cultivation and consumption, have the title of " world mushroom ".The double spores just plucked Mushroom fruitbody water content is high, easily dehydration and receive microbial infection, causes the putrid and deteriorated of fruit body of edible fungi, affects it Economic worth.The edible fungus fresh-keeping technology of China, still in the primary research stage, mainly includes preservation by low temperature, chemical reagent is protected Fresh, coating preservation etc..Preservation by low temperature is to store under cryogenic by edible fungi, and the metabolism of edible fungi reduces, idiotrophic thing Matter loss reduces, and can slow down the impact to fresh mushroom for the microorganism, thus keeping the quality of fresh mushroom;Chemical reagent is fresh-keeping mainly logical Cross the breeding suppressing microorganism and edible fungi Repiration and then extend its shelf life.Coating preservation is with natural saccharide, albumen Matter, lipid etc., as primary raw material, by coating to edible fungi surface spray, impregnating method, form one layer not after drying The transparent base film easily discovered, prevents moisture evaporation, the method that edible fungi is played with a kind of preservation and freshness of corrosion-resistanting fresh-keeping effect.Many Glucide has good film property, and gas barrier property is good, but hinders moist extreme difference.It is weak and be easily formed fine and close point that lipid has polarity The cancellated feature of son, the film water-resisting ability of formation is extremely strong, but lipid material is also easy to produce crackle or hole in film forming procedure Hole, and oxidized generation bad flavor, formed film is opaque and the shortcomings of the mouthfeel of wax taste, lipid is seldom used alone. Protein has the advantages that to be of high nutritive value, in good taste and permeability is little, and there is extremely strong emulsifying ability it is easy to lipid formed multiple Close film.Because Agaricus bisporuss surface only has one layer of thin and ventilative epidermal structure, the dehydration after leading to Agaricus bisporuss to be adopted is much high In fruits and vegetables class, and Agaricus bisporuss adopt rear respiratory intensity, at equal temperature, are 8~20 times of common fruit and vegerable, therefore double spore mushrooms Mushroom very not storage tolerance, no matter adopting polysaccharide membrane, albuminous membranae, lipid film, or the composite membrane of this three carries out fresh-keeping, is both needed to Agaricus bisporuss are placed in storage under cryogenic conditions, and shelf life also basically can not exceed 10 days.
Content of the invention
The technical problem to be solved in the present invention is to provide the coating-film fresh-keeping method of Agaricus bisporuss, and the method can be in room temperature bar The shelf life of Agaricus bisporuss is greatly prolonged under part.
The technical scheme that the present invention provides provides a kind of coating-film fresh-keeping method of Agaricus bisporuss, first by Agaricus bisporuss sporophore It is placed in immersion 10~30min in the silicate solutions that concentration is 0.1~0.6mmol/l, then carry out conventional coating preservation.
Described routine coating preservation is to carry out film guarantor with one or more of polysaccharide, protein and lipid for raw material Fresh.Particularly film is carried out for raw material with polysaccharide, protein or lipid, or with any in polysaccharide, protein and lipid Two kinds of compositionss carry out film for raw material, or the mixture of polysaccharide, protein and lipid carries out coating preservation.Film side Formula is included to Agaricus bisporuss surface spray, dipping, coating etc..
Because Agaricus bisporuss surface only has one layer of thin and ventilative epidermal structure, the pore of Agaricus bisporuss cell wall is larger, Silicate ion that can directly in absorbent solution, silicon deposits in Agaricus bisporuss cell, and siliceousization forms silicon and dash forward, prevent disease The intrusion of bacterium mycelia and extension, can reduce the enzyme degradation to cell wall for the pathogenic bacteria, play the effect of similar physical barrier, from And strengthen the resistance of disease.Silicate ion can also be with the important composition composition of Agaricus bisporuss cell wall -- and chitin produces to be handed over Connection, increased chitinous molecular chain length, and in cross-linking process, the orientation of the chitin strand crosslinked with silicon can be from Arranged in parallel become arranged anti-parallel, greatly strengthen chitinous intensity, that is, increased the intensity of edible fungi cell wall and steady Solidity, and then can stop to be seeped into outside the polyphenols in vacuole in Cytoplasm and contact with enzyme and produce brown stain, delay double Spore mushroom is old and feeble, extends its shelf life.
Described silicate is sodium silicate or potassium silicate.
Described polysaccharide is starch, modified starch, sodium carboxymethyl cellulose, the derivant of sodium carboxymethyl cellulose, plant gum Or xanthan gum.Plant gum can be guar gum, locust bean gum, sesbania gum, fenugreek gum etc..
Described lipid is one of Cera Flava, stearyl alcohol, acetyl monoglyceride, glyceryl tristearate and stearic acid or many Kind.
Described protein is in lactalbumin, soybean protein isolate, wheat gluten protein, Semen arachidis hypogaeae protein and ovalbumin One or more.
Compared with prior art, the method have the advantages that
1) present invention was first placed in silicate solutions before conventional film and is impregnated, and silicate ion is in Agaricus bisporuss Deposit in cell, siliceousization, form silicon and dash forward, prevent intrusion and the extension of pathogenic bacteria mycelia, the enzyme to cell wall for the pathogenic bacteria can be reduced Degradation, plays the effect of similar physical barrier, thus strengthening the resistance of disease.In addition, silicate ion can also be with double spores Key component chitin in the cell wall of mushroom cell produces crosslinked, the chitinous intensity of raising, thus greatly enhancing thin The steadiness of cell wall.
2) silicate impregnation and conventional painting film combination, can substantially reduce the transpiration of Agaricus bisporuss, delay Agaricus bisporuss Dehydration, the aerobic respiration intensity of Agaricus bisporuss can also be down to minimum, be unlikely to again occur anaerobic respiration, reduce nutrition become Point consumption, in addition the intensity of Agaricus bisporuss cell wall increase, defensive ability/resistance ability to external world is strengthened so that fresh-keeping through the present invention Agaricus bisporuss after method is processed can be in preservation and freshness under normal temperature condition, and freshness date is up to more than 10d.
