Abstract
A food-grade cold storage agent is prepared from components in percentage by mass as follows: 5%-15% of sodium chloride, 5%-10% of sodium carboxymethylcellulose, 2.5%-7.5% of high-fructose syrup and the balance of water. Adopted raw materials are all food-grade raw materials, so that the food-grade cold storage agent has the advantages of no toxicity, no harm and no pollution, can be widely applied to the field of cold-chain logistics, low-temperature fresh keeping, intelligent cold stations, clinical care and the like, and secondary harm of the cold storage agent to food or medicines in the storage and transportation processes is avoided.
Description
Technical field
The present invention relates to the technical field of cold-storage, specifically a kind of nontoxic, harmless, free of contamination food-grade agent for storage of coldness.
Background technology
Cool Storage Technology using effective means such as physics, chemistry, machineries, cold is stored in agent for storage of coldness, will store up when needing again
The cold deposited discharges.Produced by this technology and can efficiently store cold, meet various physics, chemical requirements again
This material is agent for storage of coldness.
Agent for storage of coldness be typically 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 a large amount of colds can be released when temperature is higher, itself and surrounding can be kept 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 chain rupture, food and the medicine of cold chain link
The wholesale market that product reach market through place of production precooling loading transport vehicle finally enters retail link storage, in these links
In the chain rupture of cold chain all easily occurs.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 running in retailer and the storage of retailer and solves the problems, such as to run in food and medicine transportation, solution
The certainly fluctuation of food and medicine storage temperatures, realizes the continuity of reserve temperature, the quality of maximized control product, improves additional
Value.
Existing Cool Storage Technology applies at present ratio wide, and the species of agent for storage of coldness also updates continuous, wherein have to chlorine
Change and add poly N-ethylene yl acetamide, Boratex in sodium water solution, make agent for storage of coldness；Also have a kind of agent for storage of coldness, be to fill in water
Divide the polyvinyl alcohol expanding and borax cross-linking reaction to generate body structure, then absorb large quantity of moisture and expand into translucent easy flowing
Gel, in addition also has and uses ammonium nitrate, ammonium chloride, sodium chloride, calcium chloride, urea, sodium carbonate, sodium sulphate, sodium nitrate etc. in a large number
Raw material adds water as 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, it is impossible to accomplish absolute nontoxic, once there is leakage in use, to transport or can be preserved
Food and medicine pollute, and then cause user or the serious consequence of eater's poisoning.Do not let out for guarantee agent for storage of coldness
Leakage, then need to improve the use cost of agent for storage of coldness and supporting cost in the packaging material that agent for storage of coldness use intensity is high, thickness is big indirectly.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of nontoxic, harmless, free of contamination food-grade agent for storage of coldness.
The present invention is adopted the technical scheme that by solving 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 and HFCS, above-mentioned
The mass percent of each component is：
Sodium chloride 5～15%,
Sodium carboxymethylcellulose 5～10%,
HFCS 2.5～7.5%,
Remaining is water.
The present invention can also adopt following technical measures：
Flavoring essence is also included, in every kilogram of food-grade agent for storage of coldness, the upper limit containing flavoring essence is 0.03 in above-mentioned food-grade agent for storage of coldness
Gram.
Food coloring is also included, in every kilogram of food-grade agent for storage of coldness, the upper limit containing food coloring is in above-mentioned food-grade agent for storage of coldness
0.05 gram.
The present invention has the advantages and positive effects that:
In the food-grade agent for storage of coldness of the present invention, the preparing raw material due to adopting is all food grade materials, gained food-grade agent for storage of coldness
Finished product is also food-grade, has nontoxic, harmless, free of contamination advantage, can be widely used in Cold Chain Logistics, low temperature is protected
The cold station of fresh, intelligence and the field such as clinical treatment, it is to avoid agent for storage of coldness causes to food or medicine in storage and transportation
Secondary hazards.When there is leakage, carrying coloured agent for storage of coldness directly can also indicate source of leaks, being conveniently replaceable.The present invention
Food-grade agent for storage of coldness low temperature flowability more preferably, be in non-condensable state all the time in use, thus can using intensity relatively
Low packaging material, thus reduce the use cost of agent for storage of coldness.
