Embodiment Construction

[0008] specific implementation plan

[0009] The present invention uses a physical method to carry out comprehensive fresh-keeping treatment, and the whole process does not use pesticides, and only uses natural fresh-keeping agents. First of all, in order to meet the requirements of export quarantine on pesticide residues and no pests and diseases, orchards are designated according to the ecological environment quality standards of green food production areas, and the production management of orchards is implemented in accordance with the green food production operating procedures to ensure the production of high-quality fruits without pests and diseases and reduce fruit borers. efficiency, reduce pesticide residues, and lay a good foundation for lychee storage and preservation. Litchi for long-term storage and transportation should be picked at eighth maturity. At this time, the fruit is basically fully developed, reaching the edible stage and the color of the pericarp has ba...

Abstract

A method for storing and transporting lychees, comprising picking lychees with a maturity of 80% in the morning on a sunny day, transporting the fresh fruits at low temperature, sorting the fruits, putting them into an aqueous ozone solution with the effects of sterilizing and degrading pesticides, rinsing and sterilizing the fruits, and then After further manual sorting, it is sent to the ultrasonic cleaning tank and accompanied by high-temperature heat treatment for further cleaning, insecticide and sterilization, and then cold treatment is carried out before entering the isolation room for gas treatment. storage. The invention realizes semi-mechanized operation, ensures good fruit rate, and provides guarantee for prolonging the fresh-keeping period; multiple times and multi-mode cleaning thoroughly kills the dirt, germs and pests on the surface of the fruit, effectively prolonging the fresh-keeping period, The preservation period is more than 40-50 days, and the good fruit rate is more than 90%, which provides conditions for the large-scale export of domestic lychees.

Description

technical field [0001] The present invention relates to a fresh fruit storage, transportation and preservation method, in particular to a storage, transportation and preservation method for freshly picked lychees. Background technique [0002] Litchi is a subtropical fruit that is difficult to keep fresh, especially at room temperature. Generally, although it can be stored at room temperature for 1 to 3 days, its color will fade and its taste will not be good. At present, the methods of keeping litchi fresh mainly include the conventional domestic cold treatment method, that is, soaking and cleaning with a low-temperature liquid phase fungicide (ice water) after picking, adding a preservative, and then packaging and refrigerating. One day; Another method is to use heat treatment first, that is, use steam at about 100°C to kill insects and bacteria, and then perform cold treatment. Treat with a special sulfur fumigator, that is, use the SO produced by burning sulfur 2 The g...
