Embodiment Construction

[0006] A technology for producing degradable edible films using pea starch,

[0007] 1. Component preparation: 80kg of pea starch, add 1000L of distilled water, 0.15L of glycerin and 2kg of sodium alginate under stirring, after homogenization, heat and stir in a water bath at 90°C until it is completely gelatinized to obtain a starch gelatinization solution.

[0008] 2. Degassing: degassing (0.5h-2h) under 0.1MPa vacuum, then let stand for 1h.

[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 a technology for producing a degradable and edible membrane by utilizing pea starch and belongs to the technical field of food processing. A main production process comprises the following steps: firstly, gelatinizing the pea starch; then, adding glycerol and sodium alginate, which can be used for increasing a membrane performance; after homogenizing and degassing, coating on a copper plate in a flowing manner; conveying the copper plate to pass through steam drying pipeline equipment by adopting a copper plate formed membrane conveyor belt; forming the membrane through cooling pipeline equipment with the relative humidity of about 50 percent; finally, winding the membrane through mechanical membrane winding equipment to prepare the degradable and edible membrane. The membrane material provided by the invention has good mechanical property, oil resisting property, moisture resisting property and oxygen resisting property. The degradable and edible membrane can be applied to various material packages of foods, health-care products, medicines, feed and the like.

Description

technical field [0001] The invention discloses a technology for producing a degradable edible film by utilizing pea starch, 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 materials integ...
