Problems solved by technology

Whether it is vegetable paper, protein film or starch film, they are all made of a single substance, which has a single nutritional component and has its own shortcomings in physical and chemical properties.
Animal protein edible film has a certain degree of flexibility, but it will change color after a long time of storage and the smell and taste are poor; simple vegetable protein film has the disadvantages of high brittleness and low strength, which need to be solved by adding auxiliary materials; vegetable paper has the physical properties of paper and contains vegetable Similar Nutrients
Moreover, when the papermaking method is used for production, due to the difficulty of peeling off the film, the method of adding additives is often used to solve the problem of difficult peeling off the film, and the preparation process is complicated.

Embodiment 1

[0023] Embodiment 1: Preparation of Chinese cabbage and soybean protein mixed paper film

[0024] According to the above description, mechanical pulping is adopted, that is, the cabbage is washed and cut into small pieces with a length of less than 10mm, and the cabbage pulp is obtained through refining, beating, fiber sorting, etc., wherein the diameter of the fiber is less than 0.3mm. Thereafter, vegetable paper was prepared by papermaking on a Fourdrinier paper machine, and the weight per unit area of ​​the obtained vegetable paper was 1.8 grams. Before papermaking and winding, apply a small amount of cooking oil to the drying cylinder or steel belt of the paper machine. While preparing vegetable paper, prepare soybean protein liquid, and its formula ratio is as follows:

[0025] 100g water, 10g soybean protein, 5g food grade glycerin, 10g food grade sodium polycarboxylate with a concentration of 1ppm.

[0026] Dissolve 10g of soybean protein powder in 100g of water, heat t...

Embodiment 2

[0027] Embodiment 2: Preparation of celery, Chinese cabbage and soybean protein mixed paper film

[0028] Take celery and cabbage in half, wash the celery and cabbage, cut them into small pieces with a length of less than 10mm, and obtain a mixed slurry of celery and cabbage through refining, beating, and fiber sorting, wherein the diameter of the fiber is less than 0.3mm. Thereafter, vegetable paper was prepared by papermaking on a paper machine to obtain vegetable paper with a weight per unit area of ​​1.5 g. Before papermaking and winding, apply a small amount of cooking oil to the drying cylinder or steel belt of the paper machine. Simultaneously in the process of preparing vegetable paper, soybean protein liquid is prepared, and its formula ratio is as follows:

[0029] 100g water, 10g soybean protein, 3g food grade glycerin, 0.3g food grade carrageenan.

[0030] Dissolve 10g of soybean protein powder in 100g of water, heat to 75°C, and stir for 30 minutes until the soy...

Embodiment 3

[0031] Embodiment 3: Preparation of celery, leek, soybean protein, potato starch mixed paper film

[0032] Take celery and leeks in half, wash the celery and leeks, cut them into small pieces with a length of less than 10mm, and perform pulping, beating, fiber sorting, etc. to obtain a mixed slurry of celery and leeks, wherein the diameter of the fibers is less than 0.3mm. Thereafter, vegetable paper was prepared by papermaking on a fourdrinier paper machine to obtain vegetable paper with a weight per unit area of ​​1.5 g. The drying cylinder or steel belt of the paper machine is coated with PTFE. Simultaneously in the process of preparing vegetable paper, prepare soybean protein powder and potato starch mixed solution, and its formula ratio is as follows:

[0033] 170g water, 15g soybean protein, 15g potato starch, 6g food grade glycerin, 0.3g food grade xanthan gum.

[0034] Dissolve 15g of soybean protein and 15g of potato starch in 170g of water, heat to 75°C, and stir f...

Abstract

The invention discloses edible mixed paper film and the producing method thereof taking the paper making process as main point. The invention aims to provide the edible mixed paper film which is made from eatable plants and vegetable protein or / and amylum and has multiple nutritive matters, and the producing method thereof. The mixed paper film of the invention comprises 40 to 70 percent of the eatable plants, 20 to 45 percent of the vegetable protein or / and amylum, and 5 to 15 percent of auxiliary materials according to the weight percentage. The invention also provides a method for preparing the mixed paper film through adopting the combination of fourdrinier making paper and sprayed liquid. The paper film of the invention is not only simple vegetable paper but also not simple protein film or starch film, the nutrition is plentiful, and the advantages of the physical and chemical characteristics of the vegetable paper and the protein film or the starch film are converged. In addition, the invention offers the producing method and the relevant technology taking the paper making process as the main, and the difficulties of the producing process and the technology are overcame. The mixed paper film can be used as an edible packaging of food, and also can be directly eaten as food.

Description

technical field [0001] The invention relates to an edible packaging material, more specifically, to a mixed paper film made of edible plants and vegetable protein or / and starch and a production method based on papermaking technology. Background technique [0002] At present, the environmental pollution caused by plastic-based packaging and waste of daily necessities has attracted the attention of the world. People are committed to finding new degradable materials, and even preparing edible packaging materials, such as vegetable paper, protein film, etc. . [0003] Vegetable paper originated in Japan, and some domestic scholars are also committed to improving research in this area. Protein film and starch film are also the focus of many scholars and some scholars' research hotspots. Protein films include animal protein films and plant protein films. Whether it is vegetable paper, protein film or starch film, they are all made of a single substance, which has a single nutri...
