Embodiment Construction

[0036] 1. Peach control group treatment

[0037] Select 20 juicy peach fruits with correct fruit, consistent maturity, good development, medium size, no mechanical damage, and maturity of 7-8, and store them directly in a high-temperature environment (35±5°C) for one week, and observe their physiological indicators and fruit changes.

[0038] 2. Ultrasonic single treatment of peaches

[0039] Choose 20 juicy peach fruits with correct fruit, consistent maturity, good development, medium size, no mechanical damage, and maturity of 7-8. Using an ultrasonic cleaner with a set frequency of 25HZ, vibrate and wash the picked peaches in water at 40°C for 10 minutes, then take them out, drain, and after drying, put the fruits evenly in the carton (the bottom pad has a Foam pads to prevent mechanical damage to the fruit), placed in refrigerated storage at 3±1°C and 85-90% humidity for 1 week, and finally out of the warehouse, placed in a high-temperature environment for storage.

Abstract

Belonging to the technical field of fresh-keeping and storage of edible fruits and vegetables, the invention specifically relates to a biophysically combined fresh-keeping and storage method for honey peaches. The method includes: utilizing a physical method to conduct ultrasonic cleaning on 70-80% mature honey peaches picked from field fruit trees, performing ultraviolet-C irradiation treatment, then using a non-toxic and efficient biological agent Bacillus subtilis to carry out spraying, then putting an ethylene absorbent into a fresh-keeping bag, finally placing the honey peaches on a shelf for storage in a clean and drafty shade place, and conducting sterilization and disinfection on the environment before storage. Compared with traditional fresh-keeping methods and single treatment, the method is safe, effective, economical, practical, is simple to operate, and has low requirement on equipment, thus not only being suitable for large-scale factory honey peach fresh-keeping operation, but also being suitable for wide adoption by fruit farmer families with certain conditions.

Description

technical field [0001] The invention belongs to the technical field of preservation and storage of edible fruits, and in particular relates to a biophysical combination preservation and storage method of juicy peaches. Background technique [0002] Because peaches are rich in nutrition, they not only have nutritional value, but also have very good medicinal value. They are sweet, sweet, and juicy, so they are very popular among people, especially for the elderly and people with bad teeth. However, due to its own characteristics, peaches are susceptible to pests and various pathogens and rotting bacteria, and are not easy to store, thus affecting their commercial value. Effective fresh-keeping and storage are a worldwide problem. At present, under normal temperature and high temperature conditions, there is no good technology at home and abroad to effectively preserve the freshness of juicy peaches. [0003] After years of research, we have fully figured out the main reasons...
