Embodiment 1

[0023] The following components are proportioned by weight: 30 parts of cassava residue, 0.5 part of sodium chloride as filler, 1 part of plasticizer glycerin, and 0.1 part of edible pigment titanium dioxide.

[0024] The preparation method of the edible food packaging film includes the following steps:

[0025] (1) First weigh the cassava residue, filler and food coloring in parts by weight, dry the cassava residue, mix with the filler and food coloring, and pulverize to 100-200 mesh. The obtained mixture of cassava residue, filler and food coloring is used as the film forming base material;

[0026] (2) Add a plasticizer to the mixture of cassava residue, filler and food coloring obtained in step (1), and mix uniformly;

[0027] (3) Add 0.25mol / L NaOH solution to adjust the pH of the solution to 7.0-9.0, heat it in a water bath at 80℃ for 30min, cast the film on a transparent plastic sheet, and dry it at 40-60℃ for 3.5h. The edible food packaging film is obtained.

Embodiment 2

[0029] The following components are proportioned by weight: 90 parts of cassava residue, 5 parts of filler anhydrous sodium sulfate, 10 parts of plasticizer glycerol, and 2 parts of food coloring zinc oxide.

[0030] The preparation method of the edible food packaging film includes the following steps:

[0031] (1) First weigh the cassava residue, filler and food coloring in parts by weight, dry the cassava residue, mix it with the filler and food coloring, and pulverize to 100-200 mesh. The obtained mixture of cassava residue, filler and food coloring is used as the film forming base material;

[0032] (2) Add a plasticizer to the mixture of cassava residue, filler and food coloring obtained in step (1), and mix well;

[0033] (3) Add 0.25mol / L NaOH solution to adjust the pH of the solution to 7.0-9.0, heat it in a water bath at 80℃ for 30min, cast it on a transparent plastic sheet, and dry it at 40-60℃ for 3.5h. The edible food packaging film is obtained.

Embodiment 3

[0035] The following components are proportioned by weight: 50 parts of cassava residue, 3 parts of sodium chloride as filler, 6 parts of plasticizer glycerin, and 1 part of edible color lithopone.

[0036] The preparation method of the edible food packaging film includes the following steps:

[0037] (1) First weigh the cassava residue, filler and food coloring in parts by weight, dry the cassava residue, mix it with the filler and food coloring, and pulverize to 100-200 mesh. The obtained mixture of cassava residue, filler and food coloring is used as the film forming base material;

[0038] (2) Add a plasticizer to the mixture of cassava residue, filler and food coloring obtained in step (1), and mix well;

[0039] (3) Add 0.25mol / L NaOH solution to adjust the pH of the solution to 7.0-9.0, heat it in a water bath at 80℃ for 30min, cast it on a transparent plastic sheet, and dry it at 40-60℃ for 3.5h. The edible food packaging film is obtained.

Abstract

The invention discloses an edible food packing film. The edible food packing film is prepared from, by weight, 30 to 90 parts of cassava residue, 0.5 to 5 parts of a filling material, 1 to 10 parts of a plasticizer, and 0.1 to 2 parts of a food colouring. The formula of the edible food packing film is reasonable; strength is high; the edible food packing film is friendly to the environment, and is capable of reducing pressure on the environment; a preparation method is simple; raw materials are cheap; and the edible food packing film is convenient for large-scale popularization and application.

Description

Technical field [0001] The invention belongs to the technical field of chemical industry, and specifically is an edible food packaging film. Background technique [0002] The output of plastic film in my country accounts for about 20% of the total output of plastic products, and it is one of the types of plastic products with a rapid increase in output. As the demand for plastic films in my country's packaging, agriculture and other fields not only increases, it is expected that the demand for plastic films in my country will increase at a rate of over 9% each year, and its market prospects are very broad. [0003] Among plastic packaging materials, the market demand for film materials has increased the most, accounting for 46% of the total plastic packaging materials. Plastic packaging films mainly include: heat-shrink packaging film, winding packaging film, food aseptic packaging film, fruit and vegetable fresh-keeping film, liquid packaging film, etc. With the continuous impro...
