Fresh-keeping method for bagged Huanghua pears

Abstract

The present invention relates to the technical field of agricultural product fresh keeping. The purpose of the present invention is to provide a fresh-keeping method for bagged Huanghua pears. According to the method, complete bagging states of the fruits are maintained during the fruit picking process and the fruit storage process; the fresh-keeping process comprises: bagging the Huanghua pear fruits, treating by 1-MCP, carrying out gradient cooling, carrying out cold preservation, carrying out gradient heating, and ex-warehousing. According to the fresh-keeping method for the Huanghua pear fruits, the complete bagging states during the fruit picking process and the fruit storage process are maintained, such that the squeezing damage and the collision damage during the processes of fruit picking, packing, carrying and storing can be prevented, the micro-ecological environment of the fruit before the fruit picking can be continued; the 1-MCP is adopted as the gas, and can enter the fruit from the carpopodium and the binding gap of the fruit bag opening so as to effectively maintain the fruit hardness and the fruit quality by inhibiting ethylene; with adopting the bagging and the high storage humidity, the transpiration water depletion during the fruit storage process is effectively controlled, such that the film packaging is not required; with the gradient cooling treatment before the cold preservation and the gradient heating treatment after the cold preservation, the low temperature damage is effectively prevented, and the quality of the Huanghua pear fruits is maintained.

Description

Technical field [0001] The invention relates to a method for refrigeration and preservation of Huanghuali fruit, belonging to the technical field of agricultural product preservation. Background technique [0002] Pear bagging cultivation technology is an effective measure to improve fruit quality. After the fruit is bagged, the fruit spots become significantly smaller and the color of the peel becomes lighter, improving the appearance of the fruit; significantly reducing pests and diseases, reducing the fruit rot rate, and also reducing sunburned fruit, bird damage, etc., increasing the fruit commercial rate; reducing smoke, pesticides, etc. Direct contamination of fruits; mechanical damage to bagged fruits is reduced. Therefore, it is widely used in practice. [0003] Huanghuali is usually harvested at high temperatures in summer and is difficult to preserve, store and transport. Therefore, post-harvest preservation of Huanghuali fruit has become an urgent problem to be ...

Problems solved by technology

[0003] Chrysanthemum pears are usually harvested when the temperature is high in summer, and it is not easy to store and transport them. Therefore, post-harvest freshness of huanghuali fruits has become an urgent problem to be solved in the circulation process.

Refrigeration is an effective way to preserve the freshness of huanghuali, but after a long period of refrigeration, the fruit is prone to dehydration, the color of the flesh becomes dark, the flavor becomes weak, and even rots
