Abstract

The invention discloses a fresh-keeping agent for melons and a fresh-keeping method thereof. The fresh-keeping agent for melons includes a soaking protectant A and a fresh-keeping film-forming agent B; the soaking protector A includes: grape seed oil, Tween80, aloe extract, and vitamin B2; Sodium chloride and distilled water; fresh-keeping film-forming agent B includes chitosan, scutellaria baicalensis extract, loofah extract and distilled water. The fresh-keeping method comprises: soaking the melon with the soaking protective agent A of the melon fresh-keeping agent, drying the melon, spraying the diluted fresh-keeping film-forming agent B on the surface of the melon, and then standing still. The special preservative for melons of the present invention and its fresh-keeping method are very effective for maintaining the fruity fragrance and taste of melons, and meanwhile the special preservatives for melons of the present invention have a certain repairing and protective effect on the damage produced on the surface of melons during mechanical treatment, And it can form a water-retaining layer and an antibacterial film on the surface of the melon, reduce the loss of water during the fresh-keeping process, play a role in sterilization and antibacterial, and at the same time maintain a good luster on the surface of the skin.

Description

technical field [0001] The invention relates to a fruit and vegetable fresh-keeping agent and a fresh-keeping method thereof, in particular to a melon fresh-keeping agent and a fresh-keeping method thereof. Background technique [0002] Melon, which belongs to Cucurbitaceae Cucurbitaceae Cucumis, is an annual herbaceous plant. Melon is a kind of economic crop with rapid development and good benefits recently, and it is one of the top ten fruits in the world, and the cultivated area of ​​melon in my country is the first in the world. However, due to the relatively concentrated production period of thick-skinned muskmelon, which coincides with the high temperature season, coupled with its intolerance to storage and transportation and its characteristics of being extremely perishable, it will bring economic losses to producers and operators. [0003] In order to solve the problem of fruit and vegetable storage and preservation and prolong the supply period of fruits on the mar...
