Embodiment 1

[0027] Embodiment 1 Configuration of film-forming material solution

[0028] Dissolve 4g soybean protein isolate in 100mL deionized water, stir and dissolve at 60°C for 15min, then raise the temperature to 85°C for modification for 30min, cool to room temperature for later use; dissolve 4g hyaluronic acid and 2g sodium carboxymethylcellulose in 100mL of deionized water was used to make a polymer solution for later use.

Embodiment 2

[0029] Configuration of embodiment 2 composite membrane

[0030] Mix the soybean protein isolate solution with the hyaluronic acid solution, then add the sodium carboxymethyl cellulose solution, and finally add the plasticizer glycerin with 10% of the total mass of the three film-forming materials, stir magnetically for 5 minutes to make the film-forming liquid mix evenly, and Add a small amount of absolute ethanol to defoam, drool on a glass plate to form a film, dry at 40°C for 24 hours, remove the film and place it in a 53% RH humidistat for more than 48 hours. See Table 1 for the changes in the ratio.

Abstract

The invention discloses a harmless and biodegradable soy protein isolate/hyaluronic acid/sodium carboxymethyl cellulose composite film and a preparation method thereof. The soy protein isolate/hyaluronic acid/sodium carboxymethyl cellulose composite film is prepared by a solution blending method, and soy protein isolate is dissolved and modified in water, mixed with a hyaluronic acid solution, and then added with carboxymethyl cellulose sodium and a plasticizer glycerin; and the mixture is stirred uniformly at room temperature to form the film by slobbering, and then the film is dried and balanced in a hygrostat. The composite film is closely arranged due to the hydrogen bonds and other forces between substrate molecules, and has good properties. The preparation method provided by the invention is simple, the cost is low, and the obtained soy protein isolate/hyaluronic acid/sodium carboxymethyl cellulose composite film has good mechanical properties and water resistance, and has better application prospects in packaging.

Description

technical field [0001] The invention belongs to the field of polymer packaging materials, and in particular relates to a soybean protein isolate / hyaluronic acid / sodium carboxymethyl cellulose composite film and a preparation method thereof. Background technique [0002] With the development of science and technology, the use of packaging materials in people's daily life is increasing. At present, the main materials used for packaging are non-degradable plastic materials based on petroleum such as polyethylene and polyvinyl chloride. At the same time as a lot of convenience, this kind of plastic packaging materials also brings negative impacts that cannot be ignored, such as the shortage of raw material petroleum, the potential harm of plastic monomers and additives to the human body, and white pollution caused by non-degradability. Therefore, the use of natural polymers to prepare green packaging materials has become one of the development trends in the packaging industry. ...
