Embodiment 1

[0037] a. Spray and clean the picked melons with clean water to remove the dust, soil and most of the microorganisms attached to the surface;

[0038] b. Evenly spray the prepared 0.01% chlorothalonil fungicide solution on the cleaned melon surface;

[0039] c. Put the melon through the conveyor belt and send it into the tunnel-type continuous microwave sterilizer. The microwave frequency is 2450MHZ and the power is 1kw. The treatment time is 600s. Harmful microorganisms attached to the skin of melon and latently infected in the field;

[0040] D, the moisture on the surface of the sterilized muskmelon is blown dry with a fan, and then the surface is waxed with edible liquid paraffin in a conventional method;

[0041] e. Put the processed melons into the inner packaging bag of the foam net cover, and then put them into the outer packaging carton, and then carry out pre-cooling and fresh-keeping storage and transportation.

Embodiment 2

[0043] a. Spray and clean the picked melons with clean water to remove dust, soil and most of the microorganisms;

[0044] b. Evenly infiltrate the surface of the cleaned melon with a concentration of 0.05% carbendazim fungicide solution;

[0045] c. Put the melon through the conveyor belt and send it into the tunnel-type continuous microwave sterilizer. The processing time in the microwave field with a microwave frequency of 2450MHZ and a power of 5kw is 300s, and the temperature of the skin layer of the melon is 30-35°C to kill the melon. Harmful microorganisms attached to the epidermis and latently infected in the field;

[0046] D, the moisture on the surface of the sterilized muskmelon is blown dry with a blower fan, then adopts a conventional method to carry out coating treatment on its surface with an aqueous solution of chitosan, and then blows it dry with a blower blower;

[0047] e. Put the processed melon into a paper packaging bag, put it into an outer packaging b...

Embodiment 3

[0049] a. Spray and clean the picked melons with clean water to remove dust, soil and most of the microorganisms.

[0050] B, evenly spraying the bactericide emulsion of 0.1% benlaite (also known as benomyl) on the cleaned melon surface;

[0051] c. Put the melon through the conveyor belt and send it to the intermittent microwave sterilizer. The processing time in the microwave field with a microwave frequency of 2450MHZ and a power of 10kw is 200s. The temperature of the melon epidermis is increased by 35-45°C to kill the melon epidermis Harmful microorganisms attached to and latently infected in the field;

[0052] d, the sterilized muskmelon is dried with a blower to dry the surface moisture, and then adopts a conventional method to wax its surface with edible liquid paraffin;

[0053] e. Pack the processed melons into the inner packing bag of the plastic bag, put the outer packing box into a plastic box, and carry out pre-cooling and fresh-keeping storage and transportati...

Abstract

The invention relates to a melon processing method after the harvesting. The method is characterized in that the picked fresh melon is sprayed and cleaned with water and then dipped in or sprayed with a disinfectant, and the surface of the melon is wet; the melon is processed in a microwave radiation field to effectively kill microorganisms which are disseminated in the field and carried on the melon skin, by means of the heat effect produced by the microwave, the galvanomagnetic effect and the combined action of disinfectant adhered on the melon surface; after disinfection, protection films are formed at the positions of the melon surface, which undergoes coating or waxing; and, in the combination with proper storage temperature, humidity control and other preserving measures, the deterioration of the melon resulted from the action of the microorganisms during the storage, transport and sale processes can be effectively reduced, the commodity ratio of the melon after storage and transport is increased, and the storage/transport period and the shelf period of the melon are prolonged. The method has the advantages of short operation time, high efficiency, energy conservation and easy large-scale production realization.

Description

technical field [0001] The invention relates to a storage and preservation method using fresh melons as raw materials. The melons are treated with microwave radiation sterilization to prolong the storage, transportation and shelf life of the melons. Background technique [0002] Melon (Cucumis melo L.), is a cultivated species in the genus Melon, an annual vine herb. The fruit is sweet and delicious, and it is a traditional summer fresh fruit that people in urban and rural areas of China generally like to eat. According to statistics, the cultivated area and output of melon in my country ranks first in the world, and ranks fifth in the world's top ten fruits after grapes, bananas, citrus, and apples. Northwest regions such as Xinjiang and Gansu are the main producing areas of melons. Because of its unique quality and flavor, melon is the best high-grade fruit after a meal. It is widely welcomed by consumers at home and abroad and is currently a best-selling fruit in the in...
