Problems solved by technology

These methods can keep fruits and vegetables fresh to a certain extent, but they all have certain defects, such as low-temperature preservation and modified atmosphere preservation methods require a large investment and are not easy to be popularized and applied; plastic films can restrain fruits and vegetables from dehydration, but they are easy to cause rot and peculiar smell; chemical preservation A large amount of organic fungicides and preservatives in the fresh-keeping method will remain on the skin of fruits and vegetables, which is poisonous to the human body

Description

technical field [0001] The invention relates to a fruit fresh-keeping agent, in particular to a grape fresh-keeping agent. Background technique [0002] Grape aliases: rose apple, grass dragon pearl, mountain gourd, plum peach, etc. It belongs to the fruit of grapes in the grape family. It is a deciduous vine and one of the oldest plants in the world. The berries are mostly spherical or elliptical, and the color varies with the variety. varies. Humans began to cultivate this kind of fruit tree a long time ago, and its output accounts for almost a quarter of the world's fruit. The nutritional value of grapes is very high, and grape juice is known as "vegetable milk" by scientists. The sugar content of grapes is 8% to 10%, mainly glucose. Among the more sugar contained in grapes, most of them are glucose that is easily absorbed by the human body, so grapes become an ideal fruit for those with weak digestion. [0003] The demand for fresh grapes in modern society is increas...
