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 cast method is used for production, due to the difficulty of removing the film, the method of adding additives is often used to solve the problem of difficult removal of the film, and the preparation process is complicated.

Embodiment 1

[0024] Embodiment 1: Preparation leek, soybean protein, cornstarch mixed film

[0025] According to the above description and the production method in Fig. 1, mechanical pulping is adopted, that is, the leeks are cleaned and cut into small pieces with a length less than 5mm, and leek pulp with a moisture content of 80-90% is obtained through refining, beating, fiber sorting, etc. material. Wherein, the diameter of the fiber is less than 0.3mm. While preparing the leek slurry, prepare soybean protein and cornstarch mixed liquid, and take a certain amount of leek slurry, and its formula ratio is as follows:

[0026] 100g water, 20g soybean protein, 5g cornstarch, 5g food grade glycerin, 20g concentration is the food grade sodium polycarboxylate of 1ppm, 60g leek slurry.

[0027] Dissolve 20g of soybean protein powder and 5g of starch in 100g of water, heat to 80°C, stir for 40 minutes, add glycerin and sodium polycarboxylate, and stir for another 10 minutes to obtain a mixture...

Embodiment 2

[0029] Embodiment 2: Preparation of cabbage and soybean protein mixed film

[0030] According to the above description and the production method in Fig. 1, mechanical pulping is adopted, that is, the cabbage is cleaned and cut into small pieces with a length less than 5mm, and the cabbage pulp with a moisture content of 80-90% is obtained through refining, beating, fiber sorting, etc. material. Wherein, the diameter of the fiber is less than 0.3mm. While preparing the cabbage slurry, prepare soybean protein liquid, and take a certain amount of cabbage slurry, and its formula ratio is as follows:

[0031] 130g water, 20g soybean protein, 10g food grade glycerin, 30g concentration is the food grade sodium polycarboxylate of 1ppm, 60g cabbage slurry.

[0032] Dissolve 20g of soybean protein powder in 130g of water, heat to 80°C, stir for 40 minutes, add glycerin and sodium polycarboxylate, and stir for another 10 minutes to obtain soybean protein liquid, cool it down to 40°C, a...

Embodiment 3

[0034] Embodiment 3: preparation celery and soybean protein mixed film

[0035] According to above-mentioned description and the production method of Fig. 1, adopt mechanical method pulping, be about to celery cleaning, cutting length is less than 5mm fritter, obtains the celery pulp of water content rate 80-90% through refining, beating, fiber sorting etc. material. Wherein, the diameter of the fiber is less than 0.3mm. While preparing celery slurry, prepare soybean protein liquid, and get a certain amount of celery slurry, and its formula ratio is as follows:

[0036] 110g water, 20g soybean protein, 10g food grade glycerin, 20g food grade sodium polycarboxylate with a concentration of 1ppm, 60g celery slurry.

Abstract

The invention discloses an edible mixed film and method for preparation, which is subject to tape casting process, and aims to provide the edible mixed film and method for preparation, which is made by edible plants and vegetable protein or / and starch and has various nutrition. According to weight percentage, the mixed film of the invention comprises 10-35 percent of edible plants, 80-50 percent of vegetable protein or / and vegetable starch, and 5-25 percent of auxiliary materials. The invention further provides a method for preparing mixed film using tape casting. Paper film of the invention is neither simple vegetable paper nor a simple protein film or a starch film, the nutrition is rich, and the invention integrates the advantages of physical and chemical properties of the vegetable paper and the protein film or the starch film. Further, the invention provides the method for preparation which is subject to the tape casting process and related technology, thereby overcoming the difficulties in the production process and technology. The mixed films are capable of being used as edible packaging of food, and also are capable of being used as food to eat directly.

Description

technical field [0001] The present invention relates to an edible packaging material, more specifically, relates to an edible mixed film made of edible plants and vegetable protein or / and vegetable starch and its production method mainly based on casting 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 su...
