Description
Technical field
This utility model belongs to field of fruit freshness keeping, especially relates to a kind of antistaling agent for grape packaging bag.
Background technology
Antistaling agent for grape stores the food additive class fresh products of time as a kind of effective prolongation Fructus Vitis viniferae, extensively should
Store in operation for Fructus Vitis viniferae both domestic and external.Under conditions of freezer environment reaches uniform temperature and humidity, by antistaling agent
The chemical reaction of sulphite and water vapor in air, generate the gaseous sulfur dioxide that Fructus Vitis viniferae is had preservation, dioxy
Change sulfur and be possible not only to kill some pathogenic bacterias causing Grape During Storage to rot such as botrytis cinerea, and to the ABA content of Fructus Vitis viniferae and second
Alkene release has obvious inhibiting effect, can alleviate the threshing in Grape During Storage, may also suppress the polyphenol oxygen at each position of fruit in storage
Change enzymatic activity.
Domestic and international existing grape fresh-keeping product is substantially this reaction principle, but due to the difference of manner of packing, directly
Connect or indirectly cause SO2The instability of gas rate of release, the too fast meeting of rate of release causes Fructus Vitis viniferae to be bleached, rate of release mistake
Slowly Fructus Vitis viniferae can be caused to rot.
Therefore, a kind of SO of design2The stable antistaling agent packaging bag of gas rate of release be this area skill urgently to be resolved hurrily
Art problem.
Summary of the invention
In view of this, this utility model is directed to one and stably discharges SO2, convenient transportation, protect without dazzling Fructus Vitis viniferae
The packaging bag of fresh dose, described packaging bag effectively optimizes antistaling agent for grape congenital defect in function, makes Fructus Vitis viniferae exist
Original color and luster and local flavor is kept in the fresh keeping time of five months.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that
A kind of antistaling agent for grape packaging bag, including wrapper and antistaling agent, described wrapper includes that ecto-entad sets successively
Laminating adhesive paper, tack coat and the supporting layer put, described laminating adhesive paper is bondd with supporting layer by tack coat, after the bending of described wrapper
Edge seal is formed and seals shirt rim, and it is internally formed containing cavity, arranges antistaling agent, the surface of described wrapper in described containing cavity
Being provided with some air-vents, the inner surface of described supporting layer is removably bonded with area can cover the resistance of all air-vents
Interlayer, the free end of described barrier layer through seal shirt rim extend to outside wrapper, the material of described barrier layer be atresia not
Gas permeable material.
Further, the material of described laminating adhesive paper is leaching membrane paper.
Further, the outer surface of described laminating adhesive paper is provided with sulfur dioxide bar.
Further, the material of described supporting layer is air-locked plastics or paper material.
Further, described antistaling agent is sulphite.
Further, the number of described air-vent is six, and is uniformly distributed in the upper surface of wrapper, described air-vent
Spacing be 10mm, a diameter of 1mm.
Relative to prior art, antistaling agent for grape packaging bag described in the utility model has the advantage that
(1) antistaling agent for grape packaging bag described in the utility model is provided with barrier layer, therein after packaging completes
Barrier layer can be pulled out when putting into Fructus Vitis viniferae storage space, in order to prevent packaging bag from consuming in transportation；
(2) antistaling agent for grape packaging bag SO described in the utility model2Rate of release is more stable, and traditional antistaling agent is big
The most dazzling mode of many employings realizes SO2The release of gas, the maximum drawback of the most dazzling mode be exactly aperture can not
Control, thus the rate of release directly contributing gas is too fast or the slowest, and the diameter of air-vent of the present utility model is extremely accurate,
Make SO2Gas, under specified aperture, uniformly, discharges slowly.
