Abstract
The invention discloses a steady-state refrigerant, which is prepared from the following components in percentages by mass: 2.5 to 5 percent of sodium chloride, 5 to 10 percent of sodium carboxymethylcellulose, 2.5 to 12.5 percent of high fructose syrup and the balance of water. As adopted preparation raw materials are all food-grade raw materials, the steady-state refrigerant provided by the invention has the advantages of being nontoxic, harmless and pollution-free, and can be widely applied to the fields of cold-chain logistics, low-temperature preservation, intelligent cooling stations, clinical medical treatment and the like; the secondary harm, which is caused by a refrigerant in storage and transportation processes, to food or a medicine 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 stable state cold-retaining agent.
Background technology
Cool Storage Technology using effective means such as physics, chemistry, machineries, cold is stored in cold-retaining agent, 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 cold-retaining agent.
Cold-retaining agent 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 pre-cooling 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 cold-retaining agent
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 seriality 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 cold-retaining agent also updates continuous, wherein have to chlorine
Change and add poly N-ethylene yl acetamide, sodium borate in sodium water solution, make cold-retaining agent；Also have a kind of cold-retaining agent, 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, carbamide, sodium carbonate, sodium sulfate, sodium nitrate etc. in a large number
Raw material adds water as cold-retaining agent.Cold-retaining agent 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 cold-retaining agent
Leakage, then need to improve the use cost of cold-retaining agent and supporting cost in the packaging material that cold-retaining agent 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 stable state cold-retaining agent.
The present invention is adopted the technical scheme that by solving technical problem present in known technology:
The stable state cold-retaining agent of the present invention, including following components：Water, sodium chloride, sodium carboxymethyl cellulose and high fructose syrup, above-mentioned each
The mass percent of component is：
Sodium chloride 2.5～5%,
Sodium carboxymethyl cellulose 5～10%,
High fructose syrup 2.5～12.5%,
Remaining is water.
The present invention can also adopt following technical measures：
Edible essence is also included, in every kilogram of stable state cold-retaining agent, the upper limit containing edible essence is 0.03 gram in above-mentioned stable state cold-retaining agent.
Food coloring is also included, in every kilogram of stable state cold-retaining agent, the upper limit containing food coloring is 0.05 in above-mentioned stable state cold-retaining agent
Gram.
The present invention has the advantages and positive effects that:
In the stable state cold-retaining agent of the present invention, the preparing raw material due to adopting is all food grade materials, gained stable state cold-retaining agent finished product
Also it is food stage, there is nontoxic, harmless, free of contamination advantage, Cold Chain Logistics, preservation by low temperature, intelligence can be widely used in
Can cold station and the field such as clinical treatment, it is to avoid the secondary danger that cold-retaining agent causes to food or medicine in storage and transportation
Evil.When there is leakage, carrying coloured cold-retaining agent directly can also indicate source of leaks, being conveniently replaceable cold-retaining agent.The present invention
Stable state cold-retaining agent low temperature flowability more preferably, be in non-condensable state all the time in use, thus can be relatively low using intensity
Packaging material, thus reducing the use cost of cold-retaining agent.
