Production technology for manufacturing edible packing paper by taking bean dregs as raw materials

Abstract

The invention relates to a production technology for manufacturing edible packing paper by taking bean dregs as raw materials. The production technology comprises the steps that the bean dregs serve as the raw materials and are put in sodium sulfite with the concentration of 3% to be steeped, the steeped bean dregs are washed clean with clear water and then ground by adding water, and grinding slurry solutions are obtained; neutral protease is added in the grinding slurry solutions for enzymolysis, dextrin, artemisia sphaerocephala krasch gum, sodium bicarbonate and palm oil are added in enzymolysis solutions, the mixture is heated to 50-55 DEG C and stirred at the stirring speed of 120 revolutions per minute for 8-10 minutes, 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, the secondary drying time is 15-18 minutes, and 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 [0001] The invention relates to the technical field of papermaking, in particular to a production process for making edible wrapping paper from bean dregs. Background technique [0002] At present, most of the materials for packaging food and medicine are plastic products. Under certain medium environment and temperature conditions, polymer monomers and some additives in plastics will dissolve and transfer to food and medicine in a very small amount, thus It can cause acute or chronic poisoning, serious teratogenicity and carcinogenicity. At the same time, because a lot of plastic products are consumed in the world every year, people discard them after use. Because plastics are extremely difficult to degrade naturally, causing serious environmental pollution, edible wrapping paper is Using natural edible substances as raw materials, a film with a porous network structure is formed through different intermolecular interactions. The film has certain nutritional...

[0002] At present, most of the materials for packaging food and medicine are plastic products. Under certain medium environment and temperature conditions, polymer monomers and some additives in plastics will dissolve and transfer to food and medicine in a very small amount, thus It can cause acute or chronic poisoning, serious teratogenicity and carcinogenicity. At the same time, because a lot of plastic products are consumed in the world every year, people discard them after use. Because plastics are extremely difficult to degrade naturally, causing serious environmental pollution, edible wrapping paper is Using natural edible substances as raw materials, a film with a porous network structure is formed through different intermolecular interactions. The film has certain nutritional value and is a degradable and edible non-polluting food packaging material. Edible packaging paper mainly has the disadvantages of easy deterioration, mildew, easy dissolution in water, and weak paper strength.
