Abstract

The invention relates to a method for producing an intelligent degradable edible film by using pea starch. The method comprises the following steps: S1, component blending, namely adding 100-120kg ofstarch into 1000L of purified water under stirring, carrying out dispersion and uniform mixing, then, carrying out further stirring for 10-15min, then, adding 40-60L of plasticizer, carrying out stirring for 10-15min, then, adding 12-18kg of fortifier, 1-1.5kg of anhydrous calcium chloride, 500-800g of plant extracts, 500-800g of natural colorant and 3-5kg of oxidized glutathione, and carrying outstirring for 30-40min; S2, homogeneous degasification; S3, tape casting; S4, drying; and S5, film uncovering, mechanical film winding, packaging and storage. The film material disclosed by the invention is capable of realizing identification of quality change of a food through color development and has good antibacterial properties, mechanical properties, oil resistance, humidity resistance and oxygen resistance. The method can be applied to packaging of various materials such as foods, health products, medicines and feeds.

Description

technical field [0001] The invention relates to a preparation method of a degradable edible film, in particular to a method for producing an intelligent degradable edible film by using pea starch. Background technique [0002] Degradable edible film is a new type of packaging material that can wrap food like paper 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 an integral part of food and serve as a Add color, flavor and nutritional value to food. The biodegradable edible film has the advantages of being safe, non-toxic, edible, non-polluting, and degradable, which is incomparable to plastic packaging. This is becoming more and more serious in the "white pollution", and most developed countries have banned or restricted the use of plastic packaging and advocated Choosing "green packaging" is undoubtedly the best choice today. Therefore, the biodegradable...
