Description
Technical field
The present invention relates to a kind of food freezing agent and its freezing and storing method of food, specifically a kind of fresh shrimp refrigerant and
Freezing and storing method.
Background technology
Shrimps species is enriched, and is of high nutritive value, but by many factors systems such as catching season, geographical conditions and weathers
About, and live in marine site, water activity is very high, during storage, transport and sale etc. more than Chang Yin and microorganism it is big
Amount is bred and easily occurs corruption, so as to reduce or lose its edibility and commodity value.At present, after the country is to processing
The fresh-keeping method of shrimp mainly uses deepfreeze technology, and conventional deepfreeze technology can not precise control of temperature, often
Damage of the ice crystal to cell can be caused, causing micro- jelly shrimp to be organized after thawing, recovery situation is poor, and cell water holding is insufficient, causes to eat
Poor taste.And the shrimp defreezing method of freezen protective is, oxidation stain and the substantial amounts of moisture of generation, there is reduction commodity value during defrosting
Shortcoming.
The content of the invention
It is an object of the invention to provide a kind of fresh shrimp refrigerant and freezing and storing method, to solve in above-mentioned background technology
The control of removal, cryogenic temperature to shrimps moisture, also shelf-life problem.
To achieve the above object, the present invention provides following technical scheme：
A kind of fresh shrimp refrigerant, its composition for constituting refrigerant is divided into two kinds：Main refrigerant and preservative；Described master is cold
Jelly agent is the mixed solution of ethanol, polyethylene glycol, propane diols and water；Wherein, described ethanol：Ethylene glycol：Propane diols：The weight of water
It is 20-30 parts to measure percentage:1-2 parts:10-20 parts:10-20 parts, wherein ethanol, polyethylene glycol, propane diols requirement are anhydrous；Institute
The preservative stated is the potassium sorbate and 1 part of activated carbon of mass ratio 1%；Produced after described main refrigerant and preservative mixing cold
Freeze agent.
A kind of freezing and storing method of fresh shrimp, comprises the following steps：
A. pre-process：Fresh shrimp is cleaned with clear water and is placed on blotting paper after draining and sucks moisture, and is repeatedly used
It is water stain that blotting paper dips in upper strata；
B. ozonization：Fresh and dried shrimp made from step a is placed in Ozone Water, shrimp need to be made to be fully immersed in water, is soaked
Handle 5~10min；
C. remove water：The moisture on shrimp surface is removed with ozone generator hair-dryer, and standing and drying；
D. refrigerant is handled：After the refrigerant prepared in advance uniformly mixing, it is -35 DEG C to be re-fed into cryogenic temperature control
Freezing processing is carried out in refrigerator, until the temperature in the temperature and refrigerator of refrigerant reaches balance；
E. refrigerant dipping freezing：Soak with ozone solution will be obtained after step c processing cross and dry up the fresh shrimp of moisture to be placed at d
In the refrigerant obtained after reason, shrimp is refrigerated to -20 DEG C by the way of dipping freezes；
F. it is vacuum-packed：Jelly shrimp after step e processing is taken out, is vacuum-packed to freezing shrimp；
G. freezen protective：The vacuum packaging that step f is obtained freezes shrimp and is put into freezen protective in -20 DEG C of freezers.
It is used as further scheme of the invention：The chill point of described refrigerant is between -30~-36 DEG C.
It is used as further scheme of the invention：Described refrigerant is carried out after freezing processing in need to being first put into refrigerator
Ability prawn is freezed.
It is used as further scheme of the invention：Described refrigerant and the weight ratio of shrimp are 1:2.
It is used as further scheme of the invention：The concentration of described Ozone Water is 0.9~1.1mg/L.
It is used as further scheme of the invention：Described vacuum packaging, vacuum is 1 × 10-3Pa。
It is used as further scheme of the invention：During defrosting, 25~35 minutes, Huo Zhechang can be placed in 4 DEG C of refrigerators
Temperature is lower to place 10~20 minutes naturally to thaw.
Compared with prior art, the beneficial effects of the invention are as follows：Freezen protective, shrimp can be preserved for a long time, and prevent quality
Deteriorate, more than half a year can be stored.After defrosting, without after-treatment shrimp, direct sabot, these shrimps are available for display sales counter and dining table,
Particularly the food selling shop of supermarket etc., can save artificial expense.In food selling shop, sale can be suitably adjusted
Amount, the economic loss for preventing stock from causing.In terms of feast table, without spending the time, substantial amounts of shrimps can be quickly provided
Food.The eating mouth feel oppressed after defrosting is good.The preservation method technique of shrimp of the present invention is advanced rationally, simple to operate, can be adapted to
Industrialized production.Packed in addition using a small amount of preservative freezing vacuum and use charcoal absorption, the peculiar smell of shrimps can be removed,
It is adapted to long-term preserve.
