Compound edible biofilm

Abstract

The invention discloses a compound edible biofilm which is characterized by comprising the following raw materials in parts by weight: 2-10 parts of starch, 25-40 parts of chitosan, 5-15 parts of soy prolamin, 1-5 parts of pullulan and 2-8 parts of a humectant. The compound edible biofilm is high in mechanical property, oxidation resistance and water and oil resistance performance.

Description

technical field [0001] The invention relates to an edible film, in particular to a composite edible biofilm. Background technique [0002] Most of the traditional food packaging materials use chemical products such as polypropylene and polyethylene. Although these materials are easy to process and low in price, they have the disadvantage of being non-biodegradable and can only be treated as domestic waste. The wide application of these materials has accelerated the white pollution problem. [0003] In view of the particularity of food packaging materials, the research and development of edible packaging materials came into being. Since the edible packaging material is non-toxic and edible, it will be automatically degraded even if it is discarded without eating, and will not cause environmental pollution. Contents of the invention [0004] The purpose of the present invention is to provide a composite edible biofilm, including the following raw materials in parts b...
