Abstract

The invention discloses a fruit and vegetable fresh-keeping film coating agent, and belongs to the technical field of agricultural additives. The fruit and vegetable fresh-keeping film coating agent provided by the invention comprises the following components: 6-8 parts of a plant germ extract, 3-8 parts of an insect extracting solution, 3-5 parts of mixed sugar, 0.1-0.2 part of a complex enzyme,10-15 parts of a nano filler, 80-100 parts of an activated chitosan liquid and 4-8 parts of a film-forming agent, wherein the plant germ consists of wheat germ, soybean germ and apple germ. In the using process, plant cells can be effectively promoted for regeneration, and a protective film is jointly constructed on the surface of the original plant cells and the film-forming framework in the product. The fruit and vegetable fresh-keeping film coating agent prepared by the technical scheme of the invention has the characteristics of antibacterial property and corrosion resistance, has an excellent film forming property and has a wide prospect in the development of the fruit and vegetable fresh-keeping industry.

Description

technical field [0001] The invention discloses a fresh-keeping coating agent for fruits and vegetables, which belongs to the technical field of agricultural auxiliaries. Background technique [0002] Fruits and vegetables are an important part of food, and their rich vitamins, minerals and other nutrients are the main source of human nutrition and are the necessities of people's life. Due to the good biological activity of fruits and vegetables, they are easily affected by environmental factors and their own effects after picking, resulting in rot and deterioration. Generally speaking, the shelf life of fruits and vegetables is short, which not only causes a lot of waste, but also has certain food safety hazards. Therefore, on the premise of maintaining the life activities of fruits and vegetables, prolong their aging process, and ensure the freshness of fruits and vegetables , prolong its shelf life, and increase the value of fruits and vegetables, has become the research ...
