Abstract

The invention discloses application of fibroin and a fruit and vegetable storage method. The fibroin is applied to the preparation of a fruit and vegetable anti-cold-injury agent. The fruit and vegetable storage method comprises the following step that the fruit and vegetable anti-cold-injury agent containing the fibroin is applied on the surfaces of fruits and vegetables. According to the scheme,the fruit and vegetable anti-cold-injury agent has a good application effect on the storage of bananas and other fruits and vegetables. According to the technical scheme, the utilized fibroin can form a layer of edible protein film on the surfaces of the fruits and vegetables, the stable structure and excellent mechanical barrier characteristics of the film can be kept due to the fact that the fibroin contains a large number of hydrogen bonds and disulfide bonds and has hydrophobic interaction force, and the fibroin can significantly inhibit the decrease of cell membrane lipids in fruit peeltissue, thereby reducing the symptoms of cold injuries. The fibroin is natural, nontoxic and harmless, is easily soluble in water, and does not need to be treated with other chemical additives, therefore, after the fruit and vegetable anti-cold-injury agent is adopted, no harmful chemical substances can remain on the surfaces of the fruits and vegetables, so that the fruits and vegetables are safer and healthier, and the edible film formed by the fibroin is completely soluble in the water and does not pollute the water after use.

Description

technical field [0001] The invention relates to the technical field of fruit storage, in particular to the application of silk protein and a method for storing fruits and vegetables. Background technique [0002] Fruits and vegetables (abbreviated as fruits and vegetables) are natural nutritious foods that contain essential nutrients such as vitamins, minerals, carbohydrates, crude fiber, protein and fat. Fruits and vegetables not only taste good, but also can promote health, and then achieve the effect of preventing and curing diseases and beautifying the skin. They are the most popular natural healthy food for modern people. After the fruits and vegetables are harvested, although they leave the mother body, they are still alive. Therefore, physiological, physical and chemical changes will continue to occur after harvesting. Therefore, how to store fruits and vegetables so that the shelf life of fruits and vegetables is longer has always been a major problem in the agricul...
