Background technology
Mushroom is second-biggest-in-the-world edible mushroom, one of Ye Shi China special product, at the title have " mountain delicacy " among the people.It is the fungi of a kind of growth on timber.Delicious flavour, fragrance oozes people, nutritious, have " plant queen " good reputation.New fresh mushroom, except moisture 85-90%, contains crude protein 19.9% in solid content, crude fat 4%, soluble N-free material 67%, crude fibre 7%, ash content 3%.Be rich in Cobastab group, iron, potassium, provitamin D (changing into vitamin D after Exposure to Sunlight), its taste is sweet, and property is put down, and cure mainly anorexia, weak breath is weak.Improve the vigor of helper T lymphocyte and strengthen human body fluid immunologic function.Facts have proved in a large number, the anti-curing cancers of mushroom in extensive range, for clinical treatment.Mushroom is also containing multivitamin, mineral matter, and to promotion human metabolism, improving organism adaptation power has great role.
After mushroom is gathered, still remain the activity of body, carry out respiration ester biochemical reaction.Cause brown stain, stem elongation, variable color, soften, moisture loss atrophy, corruption, degradation under the quality such as local flavor and quality, final parachute-opening is launched spore and is rotted.Like this, mushroom fruiting body fresh goods is caused to have perishable, that freshness date is short feature.Be convenient to mushroom transport for a long time, and extend storage time, reduce the loss, increase economic efficiency, it is necessary for carrying out fresh-keeping to mushroom.
At present, a large amount of edible mushrooms, vegetables and fruit antistaling agent have been there is on the market, the preservation that these antistaling agents can acquire a certain degree really; But, because these antistaling agents contain chemical composition human body being had to potential hazard, do not reach the safety requirements to food.
Summary of the invention
The invention provides a kind of mushroom preservation agent and preparation method thereof, the mushroom preservation time in prior art that solves short and existing mushroom preservation agent remains many and large to harm problem.
A kind of mushroom preservation agent of the present invention, it mainly realizes by the following technical programs so in addition: the raw material comprising following weight portion: shitosan 5-10 part, vitamin C 5-10 part, Tea Polyphenols 1-5 part, pulullan polysaccharide 5-10 part, sterilized water 100-120 part.
The preparation method of a kind of mushroom preservation agent of the present invention, it mainly realizes by the following technical programs so in addition: comprise the following steps: 1) shitosan, vitamin C, Tea Polyphenols and pulullan polysaccharide are added into successively in sterilized water, stir, make mixed solution; 2) step 1) gained mixed solution to be placed on ultrasonic disperse instrument ultrasonic disperse 30-60min at 40-80 DEG C, to make dispersion soln; 3) by step 2) gained dispersion soln carries out packing, sterilization, and sealing, obtains antistaling agent.
Beneficial effect of the present invention: antistaling agent of the present invention is formulated by natural biological resources such as shitosan, vitamin C, Tea Polyphenols and pulullan polysaccharides, it is directly sprayed onto the fresh intact unbroken mushroom surface after harvesting after diluting according to the volume ratio of 1:10 with water in use, easy to use, both can be used for the fresh-keeping of packed aliquot mushroom, also can be used for the fresh-keeping of mushroom of storing in a warehouse in enormous quantities; Fresh-keeping cost is low, and fresh keeping time is long, and the antistaling storing phase of mushroom can be extended to 30 days, quality control is good, fully ensure that freshness and the nutritional labeling of mushroom, without any side effects to human body, and safety and environmental protection meets the diversified demand of people to mushroom.
Detailed description of the invention
Be clearly and completely described technical scheme of the present invention below in conjunction with specific embodiments of the invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of mushroom preservation agent of the present invention, comprises the raw material of following weight portion: shitosan 5-10 part, vitamin C 5-10 part, Tea Polyphenols 1-5 part, pulullan polysaccharide 5-10 part, sterilized water 100-120 part.
The preparation method of a kind of mushroom preservation agent of the present invention, comprises the following steps: 1) shitosan, vitamin C, Tea Polyphenols and pulullan polysaccharide are added into successively in sterilized water, stir, make mixed solution; 2) step 1) gained mixed solution to be placed on ultrasonic disperse instrument ultrasonic disperse 30-60min at 40-80 DEG C, to make dispersion soln; 3) by step 2) gained dispersion soln carries out packing, sterilization, and sealing, obtains antistaling agent.
embodiment one
A kind of preparation method of mushroom preservation agent, comprise the following steps: 1) pulullan polysaccharide of the vitamin C of the shitosan of 5 weight portions, 5 weight portions, the Tea Polyphenols of 1 weight portion and 5 weight portions is added in the sterilized water of 100 weight portions successively, stir, make mixed solution; 2) step 1) gained mixed solution to be placed on ultrasonic disperse instrument ultrasonic disperse 30min at 40 DEG C, to make dispersion soln; 3) by step 2) gained dispersion soln carries out packing, sterilization, and sealing, obtains antistaling agent.
embodiment two
