Abstract

The invention discloses a storage and fresh-keeping comprehensive treatment method for Huangguan pears. The method comprises the following steps: picking, cleaning, soaking with fresh-keeping liquid, packaging and performing refrigeration, wherein the fresh-keeping liquid consists of 0.1 to 0.3 part of nisin, 10 to 20 parts of ethanol with the concentration of 70 percent, 1 to 2 parts of sorbitol, 0.2 to 0.5 part of croscarmellose sodium, 0.2 to 0.5 part of citric acid, 0.1 to 0.2 part of wheat germ powder, 30 to 60 parts of plant bactericide, 0.02 to 0.05 part of diethylaminoethyl hexanoate and 100 to 150 parts of water. According to the storage and fresh-keeping comprehensive treatment method for the Huangguan pears, provided by the invention, growth of bacteria can be inhibited remarkably, the rotting rate of the Huangguan pears is reduced and the postharvest life of the Huangguan pears is effectively prolonged; and the fresh-keeping liquid is prepared by taking pure natural traditional Chinese herbal medicine as bactericide, so a good bactericidal effect can be achieved, safety and no toxicity are realized, and potential safety hazard to human bodies is avoided.

Description

technical field [0001] The invention belongs to the technical field of post-harvest storage and processing of fruits, and in particular relates to a comprehensive treatment method for storage and preservation of Huangguan pears. Background technique [0002] Huangguan pear is a mid-maturing fine variety with the characteristics of early maturity, high quality, high resistance to black venereal disease, early fruit and early harvest, which is bred from Xuehua pear as the male parent and New Century pear as the female parent. It is one of the most recommended varieties for the adjustment of pear tree variety structure today, and is deeply loved by consumers. Due to the large output of Huangguan pears and the concentrated picking period, it is impossible to be digested and absorbed by the market in a short time after harvesting. A large number of Huangguan pears must be gradually sold after long-term storage. The Huangguan pear belongs to the respiratory climacteric fruit, and...
