Embodiment 1

[0042] Embodiment 1 The method of electronic beam irradiation in stages combined with decompression treatment of bananas

[0043] The fruit wholesale market buys green bananas without mechanical damage and without ethylene ripening. The fruit box is a corrugated box (length 50cm x width 35cm x height 20cm), and the inside of the box is padded with paper silk and other fillers to prevent mechanical damage. Packing, using electron energy of 10MeV linear electron accelerator treatment, double-sided irradiation, each surface irradiation adopts a single stage, that is, after one side of the fruit box (preferably the upper surface of the fruit box, the same below) is irradiated once, the fruit The box is turned over 180°, and the electron beam is irradiated once on the opposite surface of the single side (ie, the lower surface of the fruit box). The radiation effect box is stored in a decompression environment at room temperature (15-20°C), the absolute vacuum pressure is 20-30kPa, ...

Embodiment 2

[0047] Embodiment 2 The method of electron beam irradiation in stages combined with decompression treatment of strawberries

[0048] Harvest fresh strawberries from the greenhouse, remove rotten and other abnormal fruits, and pack them in corrugated cartons. The packaging specifications are 30cm long x 30cm wide x 25cm high, and they will be irradiated and kept fresh within 4 hours. Packing, the electron energy is 10MeV linear electron accelerator treatment, double-sided irradiation method, each surface irradiation adopts two stages, that is, after the fruit box is irradiated twice on one side, the fruit box is turned 180°, and the electron beam is irradiated on all sides. The single side facing each other is irradiated twice, the dose of single irradiation is 0.5kGy, the repeated scanning frequency of electron beam irradiation is 158pps, and the scanning width is 600mm. Put the radiation effect box into a decompression environment (temperature 10-12 ℃) for storage, the absolu...

Embodiment 3

[0052] Embodiment 3 The method of electronic beam irradiation in stages combined with decompression treatment carambola

[0053] Fresh and refrigerated Taiwan carambola are purchased in the fruit wholesale market and packed in corrugated cartons with specifications (length 52cm x width 40cm x height 20cm). The electron beam irradiation process is that the electron energy is 10MeV linear electron accelerator treatment, double-sided irradiation, each surface irradiation adopts a single stage, that is, after one side of the fruit box is irradiated once, the fruit box is turned 180°, and the electron beam The single side facing each other is irradiated once, the dose of single irradiation is 0.3kGy, the repetition scanning frequency of electron beam irradiation is 95pps, and the scanning width is 550mm. The after-irradiation box is placed in a decompression environment for storage at room temperature (15-25°C), the absolute vacuum pressure is 50-80kPa, and the relative humidity is...

Abstract

The invention discloses a method for fresh-keeping and quarantining fruits. The method comprises the following steps of (a) boxing the fruits; (b) irradiating a fruit box by utilizing an electronic beam: the total irradiation dosage of the electronic beam is 0.3 to 2.0kGy, the total irradiation times of the electronic beam is 1 to 4 times, and the single irradiation dosage of the electronic beam is 0.3 to 0.6kGy; (c) decompressing and storing: decompressing and storing the fruit box after being irradiated by the electronic beam. The low-dosage multistage irradiation of the electronic beam is combined with the decompression process, the microorganism, insect pests and enzyme activity of the fruits can be effectively inhibited or killed, so that the refreshing time and shelf life of the fruit can be effectively prolonged, and the quarantining pesticide purpose can be realized; meanwhile, the original package of the fruit does not need to be damaged in real production, so that convenience in operation is realized, and the processing capacity is strong.

Description

technical field [0001] The invention belongs to the technical field of sterilization and preservation of agricultural products, and in particular relates to a method for preservation and quarantine treatment of fruits. Background technique [0002] Plant quarantine is an extremely important factor affecting international trade in agricultural products. With the development of international trade and the improvement of trade liberalization, the impact of countries' implementation of plant and animal quarantine systems on trade has become greater and greater. Plant quarantine treatment is an important part of port inspection and quarantine. Its treatment method is not only related to the quality of goods, but also involves the lethality of harmful organisms, and also affects the cost of entry and the speed of customs clearance. The traditional quarantine treatment measures are mainly chemical fumigation, cold and heat treatment and destruction. Due to the hazards of fumigants...
