Problems solved by technology
However, when this method is used, the active ingredient of 1-methylcyclopropene is released rapidly and completely, which reduces the effective contact time between the preservative and the fruits and vegetables, which is unfavorable to the long-term preservation of fruits and vegetables.

The invention discloses a stable spray of a cyclopropene fruit-vegetable preservative, and a preparation method of the spray. The method comprises first fully mixing methyl cyclopropene with a cyclodextrin derivative solution, then adding a stabilizer and an antioxidant to the mixture, and conducting uniform stirring so as to obtain the relatively stable spray-type preservative. For use, the preservative can just be sprayed out according to a required application amount in an enclosed space, and the preservative is convenient to use. After spraying, the preservative slowly releases within 10 hours so as to realize fruit-vegetable fresh keeping. In addition, raw materials employed by the preservative are nontoxic, and harmless for human bodies and nature.
Description
technical field [0001] The invention belongs to the field of fresh-keeping of fruits and vegetables, and in particular relates to a stable spray of a cyclopropene-based fresh-keeping agent for fruits and vegetables and a preparation method thereof. Background technique [0002] my country is a big producer of fruits and vegetables. However, a large amount of fruits and vegetables are lost every year in my country because they are not effectively kept fresh after picking, which brings very large losses to the fields of fruit and vegetable planting and distribution. A large number of studies have shown that the postharvest aging and rot of most fruits and vegetables is mainly caused by the action of endogenous and exogenous ethylene. Methylcyclopropene preservatives for fruits and vegetables are currently the most effective preservatives that inhibit the action of ethylene. It can competitively inhibit the production of endogenous ethylene and the effect of exogenous ethylen...
