Abstract

The invention relates to an edible packaging film. The prior potato starch edible packaging material is undesirable in comprehensive mechanical performance and has a moisture sensitivity problem in use. The formula of the invention uses potato starch as a base material and adopts auxiliary materials including carboxycellulose, animal gum and / or vegetable gelatin, glyceride, glycerin, vegetable oil and sucrose ester or lecithin. The manufacturing process of the packaging film comprises: weighing the base material, adding water into the base material and stirring the mixture till the base material dissolves, moisturizing the solution, adding the auxiliary materials into the solution, homogenizing the mixture, vacuum degassing the mixture, film making, continuous drying the mixture, stripping film, inspecting the film, and obtaining the finished product. The physical and mechanical performance of the edible packaging film reaches the requirements on food inner packaging materials, and the edible packaging film has high isolating and sealing performance such as oxygen resistance, damp resistance and oil resistance and dispersibility in boiling water.

Description

technical field [0001] The invention relates to the field of packaging materials, especially edible packaging films. Background technique [0002] Edible packaging film is a film with a porous network structure formed by the interaction of different molecules with natural edible substances (proteins, polysaccharides, cellulose and their derivatives) as raw materials. The performance of edible packaging film has advantages comparable to those of synthetic plastic packaging film (such as obvious barrier property, which can delay the migration and diffusion of water, oil and other ingredients in food; it has good mechanical properties, which can increase food In addition to surface impact strength), it also has the characteristics of degradable, edible, and non-polluting to food and the environment. Edible packaging films based on starch have the advantages of low cost and high transparency, and are increasingly favored by researchers. [0003] Using potato modified or unmodi...
