Problems solved by technology

However, Pearl Plum is a typical climacteric fruit, and its harvest period is in midsummer, which is not conducive to storage (it matures from the end of July to the middle and late August of each year), so its storage and preservation has always been a problem
If the storage temperature is high, the hardness of the fruit will decrease rapidly, and it will easily soften, even ...

Abstract

The invention provides a crispness-keeping and cold-damage-preventing fresh-keeping method for Longtan pearl plums, and belongs to the technical field of fruit fresh keeping. The method comprises thefollowing steps: (1) pre-picking treatment is conducted, specifically, a mixed liquid medicine consisting of zeatin, N alpha-lauroyl-L-arginine ethyl ester hydrochloride (LAE) and Ca(NO3)2 is sprayedonce every other week three weeks before picking; (2) post-picking treatment is conducted, specifically, gradient cooling precooling treatment is conducted, fumigation treatment is conducted on 1-methylcyclopropene and chlorine dioxide in sequence while precooling; after precooling is conducted, an ethylene absorbent is put, a fresh-keeping bag and a box cover are sealed, storage is conducted in acontrolled atmosphere box or a refrigeration house at -1.5-0 DEG C, and temperature changing treatment is conducted every 14 d; and (3) pre-warehouse-out treatment is conducted, specifically, different gradient temperatures are adopted for re-fermentation treatment. By adopting the method, the storage period of the Longtan pearl plums can reach three months, the storage resistance of pearl plum fruits can be remarkably maintained, the sensory quality and hardness of the fruits can be maintained, and the occurrence of cold damage to the fruits can be effectively reduced.
