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

The invention belongs to the technical field of preservation and storage of edible fruits and vegetables, and in particular relates to a biophysical combination preservation and storage method of juicy peaches. The present invention uses physical methods to ultrasonically clean the 7-8 mature juicy peaches picked from field fruit trees, and after being irradiated with ultraviolet rays, sprays them with a non-toxic and efficient biological agent Bacillus subtilis, and then puts an ethylene absorbent in a fresh-keeping bag. Finally, the peaches are stored on a shelf in a clean and well-ventilated shade, and the environment is sterilized before storage. Compared with traditional fresh-keeping methods and single treatment, this method is safe, effective, economical, feasible, easy to operate, and does not require high equipment. It is not only suitable for large-scale factory fresh-keeping peach operations, but also suitable for fruit farmers with certain conditions. broadly used.

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...
