Abstract

The invention discloses a cold-resistant anti-corrosion preservation technology for cold-sensitive fruits and vegetables after being harvested, and particularly relates to a cold-resistant preservative for cold-sensitive fruits and vegetables after being harvested and a preservation method thereof. The preservative disclosed by the invention comprises methyl jasmonate (2.0-10.0mg / L) and a mixed solution, wherein the mixed solution is an ice water solution containing salicylic acid, ascorbic acid, CaCl2 and an active agent Tween 80. The preservation method comprises the steps of firstly, carrying out sealed fumigation on the cold-sensitive fruits and vegetables for 12 hours by jasmonic acid methyl ester at room temperature, soaking and carrying out cold shock on the fruits and vegetables for 1 hour in the ice water mixed solution, taking out the fruits and vegetables and airing the surface water. The cold-resistant preservative does not generate obvious symptoms of chilling injury after being placed for two weeks in an environment at 0-4 DEG C; corruption mildew and quality drop of the fruits and vegetables stored in the environment at room temperature and proper low temperature can be effectively restrained; and the refreshing time is obviously prolonged.

Description

technical field

[0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, and more specifically relates to a pollution-free, pollution-free, safe and reliable fresh-keeping agent and fresh-keeping technology for post-harvest cold-sensitive fruits and vegetables. Background technique

[0002] my country is a big producer of fruits and vegetables, and its output ranks first in the world. At present, the fruit and vegetable industry has become the pillar industry of my country's agricultural and rural economic development, but fruits and vegetables are perishable and deteriorated after harvest, and cannot be stored. Low-temperature storage and transportation is the most common means to delay post-harvest ripening of fruits and vegetables, inhibit the growth of pathogenic bacteria and maintain quality. However, one-third of the fruits and vegetables produced in my country are cold-sensitive, such as most fruits in the south and stone fruits,...
