Embodiment 1

[0019] A kind of bacteriostatic food wrapping paper of the present invention, this bacteriostatic food wrapping paper is made up of following composition by weight: 88 parts of wood pulp, 55 parts of cornstarch, 80 parts of distilled water, 1 part of taro glucomannan, karaage 3 parts of gelatin, 2 parts of soybean protein isolate, 0.5 parts of sodium hydroxide, 1 part of ethyl paraben and 3 parts of glycerin.

[0020] The preparation process of the antibacterial food wrapping paper is as follows:

[0021] 1) Extract 1 part of taro glucomannan, 3 parts of carrageenan, and 2 parts of isolated soybean protein in distilled water according to the proportion by weight, stir evenly and let it stand for two hours to swell to obtain a sol;

[0022] 2) Extract 88 parts of wood pulp by weight and carry out dissolving;

[0023] 3) Extract 55 parts of cornstarch according to the weight ratio, add 80 parts of distilled water, and stir it with a glass rod to form a high-amylose cornstarch s...

Embodiment 2

[0031] It differs from Example 1 in that the antibacterial food wrapping paper is made up of the following proportioning components in parts by weight: 135 parts of wood pulp, 120 parts of cornstarch, 155 parts of distilled water, 8 parts of taro glucomannan, carrageenan 6 parts, 9 parts of soybean protein isolate, 1.2 parts of sodium hydroxide, 7 parts of ethyl paraben and 11 parts of glycerin.

Embodiment 3

[0033] It differs from Example 1 in that the antibacterial food wrapping paper is made up of the following proportioning components in parts by weight: 105 parts of wood pulp, 75 parts of cornstarch, 121 parts of distilled water, 4 parts of taro glucomannan, carrageenan 5 parts, 5 parts of soybean protein isolate, 0.9 parts of sodium hydroxide, 4 parts of ethyl paraben and 6 parts of glycerin.

Abstract

The invention discloses bacteriostatic food wrap paper and a preparing method thereof. The bacteriostatic food wrap paper is prepared from, by weight, 88-135 parts of wood pulp, 55-120 parts of corn starch, 80-155 parts of distilled water, 1-8 parts of konjac glucomannan, 3-6 parts of carrageenan, 2-9 parts of soy isolate protein, 0.5-1.2 parts of sodium hydroxide, 1-7 parts of ethylparaben and 3-11 parts of glycerinum. All the raw materials adopted for preparing the bacteriostatic food wrap paper are edible, no chemical component is added, food can not be polluted, and safety and environment friendliness are higher; ultrasonic treatment is adopted to make the wrap paper smooth, transparent and high in tension resistance; meanwhile, added ethylparaben enables the wrap paper to have a strong bacteriostatic effect.

Description

technical field [0001] The invention relates to an antibacterial food wrapping paper and a preparation method thereof. Background technique [0002] With the development of the food industry, there are more and more types of food packaging paper. The more common ones are cake paper, candy paper, bread paper, biscuit paper, etc. Among them, waterproof and oil-proof food packaging paper is very popular, but most of them are made of polyester. Polymer compounds such as propylene are used as materials. At the same time, these materials have disadvantages such as not easy to degrade, difficult to recycle, toxic gas produced by incineration, and harmful to the ecological environment. At the same time, during the production process, chemicals such as anti-seepage agents, bleaching agents, dyeing agents, and stabilizers added to the pulp migrate in high-temperature and high-humidity environments and contaminate food. Contents of the invention [0003] The technical problem to be ...
