Five-grain powder two-way coating multi-proof biological preservative film and preparation method thereof

Abstract

The invention relates to a two-way coated multi-proof biological fresh-keeping film of whole grain powder and a preparation method thereof, the inner layer: 80-100 parts of microencapsulated plant essential oil insect-proof and mildew-proof agent, 5-10 parts of mold-proof film-forming agent, antioxidant 2-5 parts; dispersant 75-84 parts; middle support layer: 20-35 parts of low-density polyethylene resin, 70-100 parts of low-density linear polyethylene resin, 1-3 parts of fungicide; outer coating: garlic 10-15 parts of capsaicin and capsaicin microencapsulation agent, 5-8 parts of adhesive; the inner and outer layers are sprayed on the middle support layer respectively, and the two-way coating of multi-grain powder is multi-anti-biological preservative film. The fresh-keeping film utilizes the mechanism of biological prevention and control, uses biological fresh-keeping materials to carry out two-way coating of the anti-mildew functional film, and solves the problem of oxidation and slow release of the coating functional materials through microencapsulation treatment, long-term inhibition of fatty acid oxidase activity, and realizes Anti-insect, anti-mildew, anti-aging, anti-rat multi-phase regulation, delay the rancidity of whole grain powder.

Description

technical field [0001] The invention belongs to the field of packaging, and in particular relates to a two-way coated multi-anti-biological fresh-keeping film for whole grain powder and a preparation method thereof. Background technique [0002] The whole grain flour is obtained by grinding and then refined. The fat decomposition partially inhibited by the physical separation in the original grain composition is broken, the increase of free fatty acid accelerates the oxidation of fatty acid, and the automatic decomposition of peroxidized fatty acid further accelerates the deterioration of the product; And the interaction between peroxidized fatty acid and protein and other components makes the nutritional composition change. Black sesame, soybeans, black beans, walnuts and other nutritious mature powders are often added to the whole grain powder to achieve nutritional optimization. The fat content is higher than that of ordinary rice flour, which is more prone to oxidation a...

Problems solved by technology

[0003] Whole grain powder is convenient and practical, rich in nutrition, and the addition of functional ingredients makes it widely available in the market. However, it is difficult to ensure high-quality industrial sales due to easy mildew and oxidation during storage.

At present, sales methods such as fresh mills cannot solve the problem of long-term freshness preservation after people carry it around
