Abstract

The invention belongs to the technical field of agricultural food science, and particularly relates to prevention and treatment of cold damage in the postharvest storage process of pitaya. The preparation method specifically comprises the following steps: (1) selecting pitaya which is not damaged in appearance and does not turn red completely; (2) spraying a liquid medicine A 3-7 days before harvesting; (3) spraying a liquid medicine B after harvesting; (4) boxing; (5) storing at normal temperature for 6-8 hours; (6) spraying the liquid medicine B again; (7) disinfecting a refrigeration house;and (8) cooling in sequence. According to the method, peel yellowing and fruit rotting caused by cold damage and pathogenic bacteria in the low-temperature storage process of the pitaya can be obviously inhibited; the moisture loss of the pitaya is reduced, the hardness and the nutrient content of the pitaya are kept, the postharvest life and quality of the pitaya can be effectively prolonged, the original quality of the fresh pitaya preserved by the method of the invention at low temperature can still be kept on the 31st day, and the good fruit rate reaches 97% or above.

Description

technical field [0001] The invention belongs to the field of agricultural food science and technology, and in particular relates to the prevention and treatment of chilling injury in the postharvest storage process of pitaya. Background technique [0002] Dragon fruit (Hytocereus undatus Britt&Rose) is loved by consumers because of its delicious texture and rich nutritional value. Nowadays, the storage of dragon fruit is low-temperature storage, and dragon fruit is a cold-sensitive fruit, which is prone to chilling damage, manifested as skin depressions, fleshy rot, etc. At the same time, the invasion of pathogenic bacteria has further aggravated the chilling damage of pitaya, seriously affecting the quality of pitaya. quality. Therefore, how to reduce the occurrence of chilling injury in the pitaya low temperature storage process is to prolong the pitaya storage period and improve the quality of storage and transportation. [0003] Chinese patent CN201910158748.7 provides...
