Problems solved by technology

However, the single use of phase-change energy storage ice packs cannot solve the problem of deterioration and loss of food materials under low-temperature transportation conditions. At this time, it is necessary to add a certain amount of anti-mold and anti-bacterial agents to inhibit the growth of bacteria and prolong the freshness of products.
[0003] Phase-change energy storage ice packs with a single function on the market to lower the temperature of fresh ingredients such as fruits, vegetables, and seafood cannot effectively solve the problem of product deterioration and loss

Embodiment 1

[0037] The raw materials and equipment used include: multifunctional phase-change energy storage ice pack, 100 longan, 0-2℃ refrigerator, cold storage box, thermometer. The specific experimental operations are as follows:

[0038] (1) Store the multifunctional phase change cold storage ice pack in a 0~2℃ freezer for 4 hours;

[0039] (2) Select fresh longan and put them in four bags respectively, and pre-cool them for 2 hours in a refrigerated environment at 0~2℃;

[0040] (3) Place the pre-cooled longan in (2) in a closed refrigerated and incubator, and place the frozen fresh-keeping and cold-keeping multifunctional phase change cold storage ice bag in the refrigerated and incubator;

[0041] (4) Place the refrigerated incubator in a refrigerated cabinet at 0~2℃, and record and observe the surface changes of the longan. After 63 days of refrigeration test, observe the surface condition of longan. It was observed that 2 longan had mildew and the other 98 had no mildew. This shows t...

Embodiment 2

[0043] The raw materials and equipment used include: multi-functional phase change energy storage ice pack, 100 cherries, 0~2℃ refrigerator, refrigerator incubator, thermometer

[0044] (1) Store the multifunctional phase change cold storage ice pack in a 0~2℃ freezer for 4 hours;

[0045] (2) Pick fresh cherries and put them into bags, and pre-cool them for 2 hours in a refrigerated environment at 0~2℃;

[0046] (3) Place the pre-cooled longan in (2) in a closed refrigerated and incubator, and place the frozen fresh-keeping and cold-keeping multifunctional phase change cold storage ice bag in the refrigerated and incubator;

[0047] (4) Place the refrigerated incubator in a refrigerated cabinet at 0~2℃, and record and observe the surface changes of the longan. After a 90-day cold storage test, observe the condition of the cherry surface. After observation, there was mildew on the surface of 1 cherry, and no mildew on the other 99. It shows that the multifunctional phase-change ener...

Embodiment 3

[0049] The raw materials and equipment used include: multifunctional phase change energy storage ice pack, 100 blueberries, 0~2℃ freezer, cold incubator, thermometer

[0050] (1) Store the fresh and cold multifunctional phase-change cold storage ice pack in a refrigerator at 0~2℃ for 4 hours;

[0051] (2) Select fresh blueberries and put them into bags, and pre-cool them for 2 hours in a refrigerated environment at 0~2℃;

[0052] (3) Place the pre-cooled longan in (2) in a closed refrigerated and incubator, and place the frozen fresh-keeping and cold-keeping multifunctional phase change cold storage ice bag in the refrigerated and incubator;

[0053] (4) Place the refrigerated incubator in a refrigerated cabinet at 0~2℃, and record and observe the surface changes of the longan. After 63 days of refrigeration test, observe the condition of the blueberry surface. After observation, 3 blueberries showed mildew, and the other 97 showed no mildew. It shows that the multifunctional phase-...

Abstract

The invention provides a multifunctional phase change energy storage ice bag. The multifunctional phase change energy storage ice bag comprises a phase change energy storage agent, a reagent layer anda water absorption layer, wherein the phase change energy storage agent can be used as a refrigerant after being frozen, so the temperature of fruits, vegetables, seafood and other products can be reduced, respiratory action is effectively reduced, bacterium breeding is reduced, and the shelf life of products is prolonged; and the reagent layer is internally mixed with a reagent for preventing corrosion, resisting bacteria, resisting oxidation and absorbing ethylene, and is positioned on the inner side; the reagent can release gas to achieve the purposes of corrosion prevention, bacterium resistance and oxidation resistance; and the reagent has the function of absorbing ethylene gas, so the products are prevented from being ripened by the ethylene gas. According to the multifunctional phase change energy storage ice bag provided by the invention, the water absorption layer is made of a non-woven fabric which can absorb moisture on the surface of a product, exudate and air, so moisturein a bacterium breeding environment can be effectively reduced, the fresh-keeping time of the product is prolonged, and the shelf life of the product is prolonged.

Description

Technical field [0001] The invention relates to the technical field of fresh food storage, in particular to a multifunctional phase-change energy storage ice pack for keeping fresh and cold for products in the field of fresh food such as fruits, vegetables, seafood and the like. Background technique [0002] For fresh food products such as fruits, vegetables, seafood, etc., in order to avoid deterioration and rot damage during transportation and express delivery, most of them are transported under low temperature conditions, such as using heat preservation refrigerators and phase change energy storage ice packs. However, the single use of phase-change energy storage ice packs cannot solve the problem of food deterioration and loss under low-temperature transportation conditions. At this time, it is necessary to add a certain anti-mildew and antibacterial agent to inhibit the growth of bacteria and extend the product preservation cycle. [0003] Phase-change energy storage ice packs...
