Abstract
The invention relates to a production technology for manufacturing edible packing paper by taking banana peels as raw materials. The production technology comprises the steps that the banana peels serve as the raw materials and are put in sodium sulfite to be steeped, then the banana peels are washed clean with clear water and rolled repeatedly with a rolling wheel, and rolled slurry solutions are prepared; neutral protease is added in the rolled slurry solutions for enzymolysis, after unnecessary moisture is filtered out from enzymolysis solutions, dextrin, artemisia sphaerocephala krasch gum, sodium bicarbonate and palm oil are added in the enzymolysis solutions, the mixture is heated to 50-55 DEG C and stirred at the stirring speed of 40 revolutions per minute, and then pasty slurry solutions are obtained; the pasty slurry solutions are rolled into a pasty membrane with the thickness ranging from 2 si to 3 si, slit into the fixed specification and dried for the first time under microwaves with the power of 850 w and the frequency ranging from 1 GHz to 1.2 GHz; the pasty slurry solutions dried for one time are dried for the second time under microwaves with the power of 1200 w and the frequency ranging from 2 GHz to 2.5 GHz, and then the edible packing paper can be obtained. The edible packing paper not only can maintain original flavor and moisture when food is packed with the edible packing paper and but also is edible.
Description
Technical field
The present invention relates to pulp technology for making paper, be specifically related to a kind of production technology taking banana skin as raw material and make edible package paper.
Background technology
At present, the material overwhelming majority of packaged food and medicine is plastic products, under certain media environment and temperature conditions, polymer monomer in plastics and some additives meeting stripping, and very little transfer in food and medicine, thus cause acute or slow poisoning, serious even can teratogenesis carcinogenic, simultaneously because the annual plastic products consumed are a lot of in the world, abandon conveniently after people use, due to the extremely difficult natural degradation of plastics, cause serious environmental pollution, edible package paper is for raw material with edible natural material, the film with porous network structure is formed by effect between different molecular, this film has certain nutritive value, the edible pollution-free food packaging material of a kind of degradable, the edible package paper existed in the market mainly also exists apt to deteriorate, mouldy, chance water is soluble, the shortcoming that paper strength is weak.
Summary of the invention
In view of the deficiency that edible package paper in prior art exists, the object of the present invention is to provide a kind of production technology taking banana skin as raw material and make edible package paper.
The technical solution used in the present invention is, a kind of production technology taking banana skin as raw material and make edible package paper, and it take banana skin as raw material, is made up of following processing step:
1) banana skin is put into concentration be 3% sodium sulfite soak 2-3 hour after, rinse well with clear water, be repeatedly roll 4-5 time with rolling wheel under the pressure of 350-380pa at pressure, obtain rolling slurries;
2) add neutral proteinase to rolling in slurries, at 26-28 DEG C, enzymolysis 10-12 hour, obtains enzymolysis liquid;
3) enzymolysis liquid is paved on 180-190 mesh sieve body, be roll one time under the pressure of 20-25pa at pressure, after filtering excessive moisture, add dextrin, Artemisia Glue, sodium bicarbonate, palm oil wherein, be heated to 50-55 DEG C, under the stir speed (S.S.) of 40 revs/min, stir 10-15 minute obtain pasty state slurries, wherein dextrin addition be the 1%-1.5% of enzymolysis liquid weight, the xanthans addition 5%-8% that is enzymolysis liquid weight, the sodium bicarbonate addition 1%-2% that is enzymolysis liquid weight, palm oil addition is the 2%-5% of enzymolysis liquid weight;
4) pasty state slurries are rolled to thickness be the paste film of 2-3 silk, cut into fixing specification, be 850w at power, frequency is carry out primary drying under the microwave of 1GHz-1.2GHz, the primary drying time is 5-8 minute, on the pasty state slurries after primary drying, evenly spray the propylene glycol solution after one deck atomization, the propylene glycol particle after atomization is 0.8 μm ~ 1 μm, and the concentration of propylene glycol is 0.2%-0.5%;
5) be 1200w by the pasty state slurries after primary drying at power, frequency is carry out redrying under the microwave of 2GHz-2.5GHz, and the redrying time is 10-12 minute, obtains edible edible package paper of the present invention.
Beneficial effect of the present invention is, the present invention utilizes discarded banana skin to make edible package paper, not only Appropriate application waste resource, the wrapping paper environmental protection of making, not there is contaminative, the finished paper paper water imbibition made is less than 25g/ ㎡, and have good waterproof effect, stress can reach 15.9x10
5pa, bursting strength can reach 152b/cm
2pliability is close with ordinary packing paper, slurry dried forming efficiency is higher, the finished appearance quality obtained is good, and drying time is short, and continuity is good, be applicable to industrialization continuous seepage, be the edible pollution-free food packaging material of a kind of degradable, original local flavor and moisture can be kept for packaged food, again edible.
Detailed description of the invention
Take banana skin as the production technology that raw material makes edible package paper, it take banana skin as raw material, is made up of following processing step:
