Abstract
The utility model which belongs to an article for the food package is the preservative paper for preserving the freshness of the fresh and perishable food. The strong oxidizing adopting the chlorine dioxide is used as the preservative absorbed on the objects of high absorbability such as the zeolite. The utility model made from the safe chemical compound with strong oxidation and high volatilization has the advantages of no pollution and low cost, with strong bactericidal activity and favorable preserving effect, and can be made to the multiform products such as a bag, a box and a case.
Description
The utility model belongs to the packaging for foodstuff articles for use, specifically a kind ofly makes fresh, perishables keep fresh tin foil.
How making fresh, perishable fruit, vegetables keep fresh, postpone deteriorating time, is the problem that extensively exists, and also is the very difficult problem that solves.Fresh-keeping method is a lot of at present.What the most generally adopt is natural low temperature (winter) storing method; The refrigerator refrigerating method; The nitrogen-rich gas fresh-keeping method; Medicament fumigating sterilization fresh-keeping method; Fruit surface impregnation coating or the like, wherein all practical applications mostly are though all can play preservation, but the weak effect that has, the cost height that has, though have can suppress mushroom procreation and can not eliminate mushroom, though what have can sterilization but have residual hazard, has limited and has applied.
" Farmers' Daily " on November 26th, 1987 has been introduced the another kind of method that Japan is invented by China, be that zeolite is immersed in the strong oxide liquor potassic permanganate, then this zeolite is placed in the pouch of porous, again with pouch in being stored the sack that thing is encapsulated in permeable gas, can play preservation.But owing to only have potassium permanganate in the pouch, this material volatility is relatively poor, influences fresh-keeping effect, and the suction back shows red and influences outward appearance.
Goal of the invention of the present utility model is to overcome above-mentioned shortcoming, makes a kind of antistaling instant, efficient height, the tin foil that to adopt stronger volatile strong oxidizer chlorine dioxide be antistaling agent.
The utility model adopt chemical property vivaciously, stronger volatile strong oxidizer chlorine dioxide does antistaling disinfectant.At first high concentration of chlorine dioxide is fed in zeolite (or medical stone, activated carbon) the contour adsorbate (title carrier), be modulated into binder with containing aqueous solution of chlorine dioxide, starch or gelatin or silica gel again, to be adsorbed with the zeolite powder of chlorine dioxide with this binder, on common paper (also available other matrix such as plastics), last drying is handled, and promptly becomes the chlorine dioxide tin foil.
As follows below in conjunction with the description of drawings embodiment:
The saturated chlorine dioxide of newly producing is fed zeolite after 30 minutes, stop ventilation.Zeolite is ground into powdery, shown in (1) in the accompanying drawing, chlorine dioxide is fed make the aqueous solution in the water, concentration is 10～15%, shown in (2) among the figure, starch is mixed wherein again, make binder, make chlorine dioxide account for approximate 2% of binder total amount.Binder evenly is coated on the hardboard paper, shown in (3) in the accompanying drawing, more above-mentioned powdery zeolite is spread in uniform on the paper, extrusion forming is dried processing at last and promptly gets the chlorine dioxide tin foil.
The used chlorine dioxide of this tin foil is nontoxic, the non-carcinogenesis confirmed through World Health Organization, does not also cause the anticorrisive agent of the safety of genetic freak, be characterized in that oxidability is extremely strong, and volatility is very high.The various forms of tin foils of making can be used for the fresh-keeping of fresh fish, meat, fruits, greengrocery.Safe and reliable, long fresh-keeping period, effective, cost is low.Can be made into sealing, opening bag, box, box fresh-keeping article.
Accompanying drawing is illustrated as follows: 1-adsorbs the porous zeolite (or other carrier) of a large amount of chlorine dioxide, the binder that 2-prepares with things such as ClO 2 solution and starch (or gelatin, silica gel), 3-paper (or other matrix) base.
Claims (3)
1, a kind of food fresh keeping paper, it is antistaling agent to be bonded on the paper form, it is characterized in that, be carrier with high adsorbent, the absorption chlorine dioxide with the binder that aqueous solution of chlorine dioxide is mixed with, sticks to it on paper and makes.
2, chlorine dioxide tin foil according to claim 1 is characterized in that binder is with containing aqueous solution of chlorine dioxide, and concentration is 10～15%, adds that starch or gelatin or silica gel are made, and the shared weight ratio of chlorine dioxide is approximately 2%.
3, chlorine dioxide tin foil according to claim 1 is characterized in that high adsorbate can use zeolite or medical stone or activated carbon.
