Description
Technical field
The invention belongs to technical field of preservation of fresh, and in particular to a kind of mushroom coating antistaling agent and preparation method thereof.
Background technique
After mushroom picking, strong respiratory activity and metabolic activity still will do it, cause mushroom that brown stain occurs, shrink,
Nutritional ingredient missing eventually results in mushroom atrophy, rots, influences the edible value of mushroom.
The store method of mushroom in the prior art is mainly cold storing and fresh-keeping, but cold storing and fresh-keeping is mainly to inhibit micro- life
The principle of object growth, but this kind of method stores need to expend a large amount of energy for a long time, and mushroom is also in cold storage procedure
It will do it certain metabolic activity, nutritional ingredient, which has, to be significantly lost, and further needing exist for auxiliary other methods could reach
To good preservation effect.
The Chinese invention patent application of Publication No. CN105285081A discloses a kind of antifaling agent of edible fungus and its preparation
Method, the antistaling agent include the raw material of following parts by weight:It is 5-10 parts of chitosan, 5-10 parts of vitamin C, 1-5 parts of potassium sorbate, general
5-10 parts of Shandong orchid polysaccharide, 100-120 parts of sterile water, which additionally provides the preparation method of above-mentioned antifaling agent of edible fungus, will be upper
Raw material mixing is stated, ultrasonic disperse dispenses.Antistaling agent of the invention is directly sprayed onto the edible mushroom after picking after dilution
Surface, it is easy to use, it can be not only used for the fresh-keeping of packed aliquot edible mushroom, it can also be used to the guarantor of high-volume storage edible mushroom
It is fresh;Fresh-keeping at low cost, fresh keeping time is long, the antistaling storing phase of edible mushroom can be extended to 30 days, and quality control is good, sufficiently protects
The freshness and nutritional ingredient of edible mushroom are demonstrate,proved, safety and environmental protection without any side effects to human body meets people to edible mushroom
Diversified demand.But the invention is main fresh-keeping ingredient with chitosan, fresh-keeping effect is poor, and nutrient loss is tight
Weight.
Notification number is the Chinese invention patent of CN101766222B, discloses fresh-keeping liquid and its preparation side of a kind of edible mushroom
Method, the mass percent of each raw material are sodium acetate 0.05%-0.1%, sodium chloride 0.1%-0.2%, potassium sorbate 0.01%-
0.03%, ascorbic acid 0.02%-0.05%, acidic ph modifier 0.5%-3%, calcium preparation 0.2%-2%, chitosan
0.05%-0.1% dissolves above-mentioned raw materials in water.The present invention is used for edible fungus fresh-keeping, simple and easy to operate, and safety and sanitation,
It is of good preservation effect;But the invention fresh-keeping effect is poor, nutrient loss is serious.
Summary of the invention
The object of the present invention is to provide a kind of mushroom coating antistaling agent and preparation method thereof, which can be big
Width improves the fresh keeping time of mushroom, but also can reduce the loss of nutritional ingredient.
To achieve the above object, the present invention provides the following technical solution:

The big substance of compound, anthocyanidin, phenolic acid etc. four, can significantly inhibit the growth and breeding of bacterium, be formed on mushroom surface
Layer protecting film prevents the pollution of microorganism, reduces loss of water, and tea polyphenols can inhibit the activity of enzyme in mushroom, prevent from becoming
Color guarantees appearance, can also prevent the oxidation of the substances such as the unsaturated fatty acid in mushroom from mushroom corruption and modified konjaku being caused to form sediment
Powder mutually acts synergistically, and can be further improved its fresh-keeping effect.
(4) present invention also added Natamycin, and natamycin has very in terms of inhibiting the growth of saccharomycete and mould
Strong effect, and the formation of aflatoxin and the formation of mycotoxin can also be prevented, in addition natamycin to human body without
Evil, and microorganism is difficult to generate resistance to it.
(5) present invention also added the substances such as chitin, and the nutriment of mushroom can be further prevented to be lost, avoid it
Appearance and fragrance change.
(6) present invention is stirred mixing to raw material using mulser, can play extraordinary dispersion effect, may be used also
So that material is more fine and smooth, the fresh-keeping effect of the film of its formation is improved.
