1-methyl-3-(2-methylcyclopropane)-1-cyclopropene inclusion complex for keeping fruits, vegetables and flowers fresh and preparation method thereof

Abstract

The invention discloses a 1-methyl-3-(2-methylcyclopropane)-1-cyclopropene stable inclusion complex for keeping fruits, vegetables and flowers fresh, which is characterized in that: the inclusion complex is formed by reaction of 1-methyl-3-(2-methylcyclopropane)-1-cyclopropene and cyclodextrin. The inclusion complex is a solid fruit, vegetable and flower fresh-keeping agent material. The 1-methyl-3-(2-methylcyclopropane)-1-cyclopropene gas serving as an effective ingredient in the inclusion complex accounts for 0.001 to 4.5 weight percent of the fresh-keeping agent. The inclusion complex is mainly used for keeping the fruits, vegetables and flowers with climacteric after-ripening aging fresh, and particularly has predominant fresh-keeping effect on leaf vegetables and fruits. The inclusion complex has the advantages of high effective ingredient, difficult oxidation, convenience for use and low cost, and is easy for storage and transportation; and the preparation method is performed at normal pressure, has the advantages of simple process, safety, reliability, high product yield and low cost, and is easy for implementation.

Description

technical field [0001] The invention belongs to the technical field of preservation, and in particular relates to an inclusion compound of 1-methyl-3-(2-methylcyclopropane)-1-cyclopropene used as a preservative for fruits, vegetables and flowers and a preparation method thereof. technical background [0002] At present, the proportion of fruits and vegetables in fresh-keeping storage in my country is relatively small. Due to poor fresh-keeping treatment, the annual consumption rate of fruit products is 20% to 25%, the annual loss rate of vegetables is as high as 30%, and the annual loss of fruits and vegetables is hundreds of millions of tons. . At the same time, with the continuous improvement of the quality of life of the people, the people hope to eat fresh and delicious fruits and vegetables all year round, and decorate their living environment with flowers, the preservation technology of fruits, vegetables and flowers has emerged as the times require.
