Embodiment Construction

[0006] A technology for producing degradable edible films using soybean protein,

[0007] 1. Component deployment: 90kg soybean protein, add 1000L distilled water, 0.20L glycerin, 1.2kg konjac gum and 2kg carboxymethyl cellulose sodium under stirring to adjust the acidity of the membrane solution, heat and stir in a water bath at 90°C until homogenized Complete reaction to obtain a membrane solution.

[0008] 2. Degassing: degassing under 0.1MPa vacuum (0.5h-2h).

[0009] 3. Casting: Set the width and height of the scraper according to the film thickness requirements, and cast on the copper plate conveyor belt that can control the film thickness.

[0010] 4. Drying: The copper plate film-forming conveyor belt first passes through the steam drying pipeline equipment, and then passes through the cooling pipeline equipment with a relative humidity of about 50% to form a film.

[0011] 5. Film removal: mechanical roll film, packaging and storage.

Abstract

The invention provides technology for producing a vegetable protein and konjac glucomannan composite degradable and edible film, belonging to the technical field of food processing. The technology comprises the following main production processes: mixing and stirring soy protein, glycerin, konjac glucomannan and sodium carboxymethylcellulose; heating the materials to react; then carrying out tape casting on the film solution on a copper plate through homogenization and degasification; adopting a copper plate film forming conveyer belt to firstly pass through steam drying pipeline equipment and then pass through cooling pipeline equipment with relative humidity being about 50% to form a film; and finally adopting mechanical film rolling equipment to roll the film, thus producing a degradable and edible film with high strength. The film material has good mechanical performance and oil, moisture and oxygen resistance. The film can be applied to packaging of various materials such as food, health products, drugs, feed and the like.

Description

technical field [0001] The invention discloses a production technology of plant protein konjac gum composite degradable edible film, which belongs to the technical field of food processing. Background technique [0002] Degradable edible film is a new type of packaging material that can be coated to keep fresh and can be processed into bags, boxes and other packaging forms to replace traditional synthetic packaging materials such as plastics. At the same time, it can also be a component of food and add to food. Color, fragrance and nutritional value. The degradable edible film has the advantages of no pollution and degradability, which is incomparable to plastic packaging. This is becoming more and more serious in the "white pollution". Today, most developed countries have banned or restricted the use of plastic packaging and advocated the use of "green packaging". Undoubtedly the best choice. Therefore, the preparation technology of degradable edible film packaging materi...
