Abstract

The invention discloses a grape preservative. The preservative is prepared from the following raw materials in parts by weight: 50-100 parts of fructose, 10-20 parts of sodium hydroxide, 5-15 parts ofstearic acid, 10-20 parts of calcium chloride, 5-15 parts of citric acid, 3-10 parts of vitamin C, 3-10 parts of sodium hexametaphosphate, 3-10 parts of beta-aminobutyric acid, 3-10 parts of tartaricacid and 500-1000 parts of water. The preservative prepared by using the raw materials of the invention does not change the taste of grapes after being used, and fresh-keeping time is long. The preservative has good inhibiting effect on pathogenic bacteria, reduces bad fruit rate and spike-stalk browning index during grape storage, and does not cause harm to human health even if part of the preservative is used by human body.

Description

technical field [0001] The invention relates to a grape antistaling agent and a preparation method thereof, belonging to the field of antistaling agent preparation. Background technique [0002] Grape is a very popular fruit, so it is widely planted. But after the grapes are ripe, they are not easy to preserve and are extremely perishable. For planting farmers, if they do not sell in time, it will cause greater economic losses. For this reason, people eat preservatives to keep fresh grapes. However, during the use of the existing antistaling agents, the taste of the grapes becomes worse after preservation, and the antistaling agents tend to remain on the surface of the grapes, which is harmful to human health. Contents of the invention [0003] The object of the present invention is to provide a grape preservative and a preparation method thereof. After the grape fresh-keeping agent keeps grapes fresh, it will not change the taste of the grapes, and will not endanger h...
