Method for keeping persimmon brittle and fresh

Abstract

The invention discloses a method for keeping persimmon brittle and fresh. The method comprises the following steps: 1) building a closed plastic greenhouse; 2) fumigating, namely, placing the selected persimmon into the plastic greenhouse, stacking and arranging in general way, quickly adding 10 to 20mg / kg of 2, 4-dichlorphenoxyacetic acid and 0.5 to 5 microliter per liter of 1-methylcyclopropene to the plastic greenhouse, immediately sealing the greenhouse, and fumigating for 10 to 48 hours; 3) performing fresh keeping packaging treatment, namely, wrapping single fumigated persimmon with a foamed PE mesh sleeve, and then transferring into a packaging box formed by a polyethylene storage bag; 4) precooling, namely, precooling the packaging box for 12 to 24 hours under the temperature of -1 to 0 DEG C, wherein an opening of the polyethylene storage bag is completely opened during precooling; and 5) storing, namely, binding the opening of the polyethylene storage bag, and stacking and storing in a frozen warehouse at the temperature of 4+ / -0.5 DEG C. With the adoption of the method, the storage life of the persimmon can be increased to 9 to 10 months, and the effect of keeping brittle and fresh is good.

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.
