Abstract
A kind of food-grade agent for storage of coldness, including following components：Water, sodium chloride, sodium carboxymethylcellulose, sodium alginate and dietary cellulosic, the mass percent of above-mentioned each component are：Sodium chloride 5~15%, sodium carboxymethylcellulose 2.5~5%, sodium alginate 1~3%, dietary cellulosic 2.5~5%, remaining is water.Because the preparing raw material used is all for food grade materials, the food-grade agent for storage of coldness finished product of the present invention is also food-grade, with nontoxic, harmless, free of contamination advantage, the fields such as the cold station of Cold Chain Logistics, preservation by low temperature, intelligence and clinical treatment can be widely used in, avoid agent for storage of coldness secondary hazards to caused by food or medicine in storage and transportation.
Description
Technical field
The present invention relates to the technical field of logistics refrigeration, specifically a kind of food-grade, nontoxic, harmless, free of contamination food
Grade agent for storage of coldness.
Background technology
Cool Storage Technology cold is stored in agent for storage of coldness using effective means such as physics, chemistry, machineries, it is necessary to when again will storage
The cold deposited discharges.Cold can efficiently be stored by being produced by the technology, meet various physics, chemical requirements again
This material is agent for storage of coldness.
Agent for storage of coldness be typically it is a kind of by organic or（With）The sticky colloidal mixture of inorganic compound composition, can be at low temperature
Absorb and store a large amount of colds, and when temperature is higher, and can releases a large amount of colds, can keep itself and surrounding the long period
The low temperature environment of a small range.
Subject matter present in the cold chain transportation such as food and medicine vaccine field is the chain rupture of cold chain link, food and medicine
The wholesale market that product reach market by place of production precooling loading transport vehicle finally enters retail link storage, in these links
In all easily there is the chain rupture of cold chain.Can effectively solve to be pre-chilled to transport vehicle and from wholesale city from the place of production using agent for storage of coldness
Field reaches the problem of being run into the storage of retailer and retailer and solves the problems, such as to run into food and medicine transportation, solves
The certainly fluctuation of food and medicine storage temperatures, the continuity of reserve temperature is realized, the maximized quality for controlling product, improved additional
Value.
Than wide, the species of agent for storage of coldness is also constantly updating the application at present of existing Cool Storage Technology, wherein some is to chlorine
Change and poly N-ethylene yl acetamide, Boratex are added in sodium water solution, agent for storage of coldness is made；Also a kind of agent for storage of coldness, filled in water
Point expansion polyvinyl alcohol and borax cross-linking reaction generation body structure, then absorb large quantity of moisture be expanded into it is translucent easily flowing
Gel, also have in addition largely using ammonium nitrate, ammonium chloride, sodium chloride, calcium chloride, urea, sodium carbonate, sodium sulphate, sodium nitrate etc.
Raw material adds water to be agent for storage of coldness.Agent for storage of coldness common problem of the prior art is the introduction of substantial amounts of industrial chemicals to improve
The indices of cold-storage, can not accomplish it is absolute nontoxic, can be to transporting or storing if leakage occurs in use
Food and medicine pollute, and then trigger the serious consequence of user or eater's poisoning.To ensure that agent for storage of coldness is not let out
Leakage, then the use cost of agent for storage of coldness and supporting cost need to be improved indirectly in the packaging material that agent for storage of coldness use intensity is high, thickness is big.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of food-grade, nontoxic, harmless, free of contamination food-grade agent for storage of coldness.
The present invention is adopted the technical scheme that to solve technical problem present in known technology:
The food-grade agent for storage of coldness of the present invention, including following components：Water, sodium chloride, sodium carboxymethylcellulose, sodium alginate and meals
Cellulose, the mass percent of above-mentioned each component are：
Sodium chloride 5~15%,
Sodium carboxymethylcellulose 2.5~5%,
Sodium alginate 1~3%,
Dietary cellulosic 2.5~5%,
Remaining is water.
The present invention can also use following technical measures：
Also include flavoring essence in above-mentioned agent for storage of coldness, the upper limit containing flavoring essence is 0.03 gram in every kilogram of agent for storage of coldness.
Also include food coloring in above-mentioned agent for storage of coldness, the upper limit containing food coloring is 0.05 gram in every kilogram of agent for storage of coldness.
The present invention has the advantages and positive effects of:
In the food-grade agent for storage of coldness of the present invention, because the preparing raw material used is all for food grade materials, gained agent for storage of coldness finished product
For food-grade, there is nontoxic, harmless, free of contamination advantage, Cold Chain Logistics, preservation by low temperature, intelligence can be widely used in
The field such as cold station and clinical treatment, avoid agent for storage of coldness secondary danger to caused by food or medicine in storage and transportation
Evil.When leaking, source of leaks can also be directly indicated with coloured agent for storage of coldness, is conveniently replaceable agent for storage of coldness.The present invention
Food-grade agent for storage of coldness low temperature flowability it is more preferable, be in non-condensable state all the time in use, thus can use intensity compared with
Low packaging material, so as to reduce the use cost of agent for storage of coldness.
