Description
Technical field
The utility model relates to a kind of fresh-keeping laminates, belong to preserving fruit and vegetable utilizing field.
Background technique
In recent years, the fruits and vegetables industry (including industry of flowers and plants) in China achieves great achievement, and fruits and vegetables yield is huge, but is storing up
During fortune as ripening and senscence, rot etc. caused by lose it is also surprising, currently, fruits and vegetables harvesting after rationally effective preservation and freshness
Technology is by the common concern of industry.
Utility model people knows to disclose a kind of feed system of compound cyclopropene, the system be include an at least base
The compound cyclopropene generator of material, the material containing at least one compound cyclopropene and releasing agent, one of substrate
At least one side uses the material coating containing at least one compound cyclopropene and wherein when containing at least one compound cyclopropene
Material releasing agent when, release gas compound cyclopropene.The case is to adopt 1-MCP/ alpha-cyclodextrin complex in advance
It is configured to solution with solvent (such as polyvinylpyrrolidone), then to be coated on substrate, in use, making the substrate and releasing
Agent contact is put, to discharge gas compound cyclopropene.Contain a large amount of chemistry in the compound cyclopropene generator that the case provides
Reagent, when being applied to preserving fruit and vegetable utilizing, there are insecurity factors；During the preparation process, used solvent pollutes the environment, this
Outside, due in use, needing to contact with releasing agent, the product is inconvenient to use.
In addition, utility model people knows that this field can uniformly discharge 1- not yet as the practitioner in preserving fruit and vegetable utilizing field
The content of the technology of MCP, the 1-MCP of existing product is very uneven, and unit area 1-MCP content difference is very big, Wu Fabao
The effect for demonstrate,proving actual use, if 1-MCP content is big, endogenous ethylene is over-constrained inside fruits and vegetables, and storage phase is caused nothing occur
Method after-ripening influences fruit-vegetable quality, if 1-MCP content is few, endogenous ethylene can not effectively inhibit inside fruits and vegetables, causes fruits and vegetables
It rots to cause damages after softening occurs in storage phase.Think that the technical issues of solution 1-MCP uniformly discharges always this field is long-term
Technical problems to be solved, thus, if can solve the technical problem, it is bound to bring to preserving fruit and vegetable utilizing field significantly
Progress.

The liner of grape packing box, for the non-printed side of fresh-keeping laminates towards the grape in packing box, sealing packaging box keeps grape to exist
Storage in one closed environment (packing box external environment holding conditions: 0 DEG C, relative humidity is 90%).The water of grape release
Gas enters medicament layer through upper layer and lower layer substrate, releases 1-MCP gas.By storage experiment it is found that this implementation in this experiment
The acquisition time of 1-MCP was at 12-48 hours in the fresh-keeping laminates of example, and storing, 30 days grape carpopodiums are emerald green, and nothing falls a phenomenon, nothing
Rot grape berry.
0.03m is cut by 1Kg cherry2The above-mentioned fresh-keeping laminates 1 being prepared of area, as in cherry packing box
Lining, for the non-printed side of fresh-keeping laminates towards the cherry in packing box, sealing packaging box keeps cherry in a closed environment
Middle storage (packing box external environment holding conditions: 2 DEG C, relative humidity is 80%).Through overtesting it is found that this implementation in this test
The acquisition time of 1-MCP was at 12-48 hours in the fresh-keeping laminates of example, and cherry fruit is moist after storage 20 days, kept preferably hard
Degree, no putrefactive phenomenon.
On 1Kg prune is fresh-keeping, 0.05m is cut2Fresh-keeping laminates 2, it is fresh-keeping laminated as the liner of prune packing box
The non-printed side of object keeps prune to store (packaging in a closed environment towards the prune in packing box, sealing packaging box
Box external environment holding conditions: 2 DEG C, relative humidity is 80%).Above and below the respiration heat water vapo r transmission that prune generates after packaging
Two layers of substrate enters medicament layer, releases 1-MCP gas.Through overtesting it is found that this test in the present embodiment fresh-keeping laminates
The acquisition time of middle 1-MCP was at 12-48 hours, and prune fruit colour is delicious after storage 30 days, and soluble solid content is constant,
The hardness of fruit preferably is maintained, has no phenomena such as mildew is rotted.
On 7Kg cherry is fresh-keeping, long 36.5cm, the fresh-keeping laminates 3 of the rectangle of wide 25cm are intercepted.As cherry packing case
Liner, the non-printed side of fresh-keeping laminates is towards the cherry in packing case, sealed package case, keeps cherry closed at one
Storage in environment (packing case external environment holding conditions: 2 DEG C, relative humidity is 60%).By experiment it is found that this in this test
The fresh-keeping laminates of embodiment can make the storing cherry period extend to 30 days by 5 days, and cherry fruit is moist, keep preferable hardness,
Without putrefactive phenomenon.
Using on 15Kg banana (golden any of several broadleaf plants, bow any of several broadleaf plants) is fresh-keeping, long 46cm, the wide fresh-keeping laminates 4 of 28cm rectangle need to be cut.
As the liner of banana (golden any of several broadleaf plants, bow any of several broadleaf plants) packing case, the printing surfaces of fresh-keeping laminates is towards banana (the golden any of several broadleaf plants, bow in packing case
Any of several broadleaf plants), sealed package case, keeping banana (golden any of several broadleaf plants, bow any of several broadleaf plants), (packing case external environment stores item for storage in a closed environment
Part: 24 DEG C, relative humidity is 78.5%).The water vapo r transmission upper layer and lower layer substrate generated after banana breathing enters medicament layer, discharges
1-MCP gas out.By storage experiment it is found that this experiment in the present embodiment fresh-keeping laminates in 1-MCP acquisition time in 4-8
It or so guarantees that banana is stored shelf life extension 5 days or more, and in After-ripening fruit color transformation, softening and starch water
Solution is normal, to guarantee its edible and commodity value.

0.0010mg、0.0024mg、0.0000mg、0.0030mg、0.0000mg、0.0000mg、0.0000mg、
0.0000mg、0.0000mg、0.0007mg。
Gas content average value by testing 1-MCP is 0.0007mg, but inconsistent by the sample data of equal portions, poor
Away from big.Through testing it is found that the market brand preserving fruit and vegetable utilizing pad, the uniformity of 1-MCP are poor, it might even be possible to say without uniformly
Degree.
Finally, it is stated that: above embodiments are merely to illustrate the implementation process and feature of the utility model, rather than limit
