Crisp-keeping and freshness-keeping method for persimmons

Abstract

The invention discloses a crisp-keeping and freshness-keeping method for persimmons. The crisp-keeping and freshness-keeping method includes following steps: 1) building a closed plastic large tent; 2) fumigating: placing the sorted persimmons into the plastic large tent, stacking the persimmons generally, successively rapidly placing 1- methylcyclopropene, secondary butyl amine and tecto into the plastic large tent, immediately sealing the plastic large tent, and fumigating for 10-48 hours; 3) keeping freshness and packaging: sleeving foaming PE (polyethylene) net sleeves on single fumigated persimmons one by one, and filling the persimmons into a packaging box lined with a polyethylene freshness-keeping bag with the thickness ranging from 0.02mm to 0.04mm; 4) pre-cooling: pre-cooling the packaging box for 20-36 hours in an environment with the temperature ranging from minus 1 DEG C to 0 DEG C, and leading an opening of the polyethylene freshness-keeping bag to be opened completely in a pre-cooling process; 5) storing; and 6) delivering from a warehouse and removing puckery. By the aid of the crisp-keeping and freshness-keeping method, the storage period of the persimmons is prolonged to 4 months to 8 months, a crisp-keeping and freshness-keeping effect is good, and the method can meet the requirement that the persimmons produced at a production season can be sold and supplied all the year round.

Description

technical field [0001] The invention relates to the technical field of agricultural product storage, in particular to a crisp and fresh-keeping method for persimmons. Background technique [0002] At present, traditional storage methods are still used for persimmons in my country, such as indoor storage, open-air storage, and natural freezing. Due to the late commercial cultivation of sweet persimmons in our country, the total planting amount is not large, and there are no sweet persimmon products that have undergone serial storage and fresh-keeping technology for sale in the market. The traditional simple storage technology is easy to operate and requires little investment. It is deeply loved by fruit farmers and plays an important role in satisfying the domestic fresh fruit market and sweet persimmon processing. However, the traditional simple storage method has the problems of short storage period and severe soft rot, which cannot meet the needs of seasonal production, a...

Problems solved by technology

However, the traditional simple storage method has the problems of short storage period and serious soft rot, which cannot meet the needs of seasonal production, annual sales and annual supply. Therefore, it is urgent to develop a persimmon preservation technology with a long storage period and good crispness and freshness.
