A kind of fresh-keeping method of persimmon

Abstract

The invention discloses a crisp and fresh-keeping method for persimmons, which comprises the following steps: 1) establishing an airtight plastic greenhouse; 2) fumigation treatment: firstly put the picked persimmons into the plastic greenhouse, place them in conventional pallets, and then place them in the plastic greenhouse; Put 2,4-dichlorophenoxyacetic acid and 1-methylcyclopropene into the plastic greenhouse quickly, seal the plastic greenhouse immediately, and fumigate for 10-48h, the dosage of 2,4-dichlorophenoxyacetic acid is 10-20mg / kg , the concentration of 1-methylcyclopropene in plastic greenhouses is 0.5-5μL / L respectively; 3) Fresh-keeping packaging treatment: After the fumigated persimmon single fruit is covered with a foamed PE net cover, it is packed into a polyethylene fresh-keeping bag. 4) Pre-cooling: pre-cool the above-mentioned packing box for 12-24 hours at -1-0°C, and open the opening of the polyethylene fresh-keeping bag completely during the pre-cooling process; 5) Storage: Put the polyethylene fresh-keeping bag The pockets of the bags are tied tightly, and they are stacked and stored in a cold storage at a temperature of 4±0.5°C. The method for keeping the crispness and freshness of the persimmons of the invention can increase the storage period of the persimmons to 9-10 months, and has a good crispness and freshness preservation effect.

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.

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.
