Embodiment 1

[0011] A kind of blueberry fresh-keeping method utilizing ultraviolet radiation, comprises the steps:

[0012] (1) Spread the picked blueberries on the irradiation device, and turn on the ultraviolet disinfection lamp for irradiation under the condition of no one in the room. The radiation intensity of the ultraviolet disinfection lamp is 7 μw / cm 2 , the irradiation time of the ultraviolet disinfection lamp is 8 hours.

[0013] (2) After the ultraviolet disinfection lamp is irradiated, wrap the blueberries in plastic wrap for storage.

[0014] The method adopts ultraviolet disinfection lamps with low radiation intensity to irradiate blueberries for a long time, kills microorganisms attached to the surface of blueberries, slows down the rotting speed of blueberries, and realizes preservation of blueberries. The method requires low equipment, does not affect the taste of the fruit, has no residue, maintains the nutritional content of the fruit, and is simple to operate and easy...

Embodiment 2

[0016] A kind of blueberry fresh-keeping method utilizing ultraviolet radiation, comprises the steps:

[0017] (1) Spread the picked blueberries on the irradiation device, and turn on the ultraviolet disinfection lamp for irradiation under the condition of no one in the room. The radiation intensity of the ultraviolet disinfection lamp is 5 μw / cm 2 , the irradiation time of the ultraviolet disinfection lamp is 12 hours.

[0018] (2) After the ultraviolet disinfection lamp is irradiated, wrap the blueberries in plastic wrap for storage.

[0019] The principle and effect of this method are the same as in Embodiment 1.

Embodiment 3

[0021] A kind of blueberry fresh-keeping method utilizing ultraviolet radiation, comprises the steps:

[0022] (1) Spread the picked blueberries on the irradiation device, and turn on the ultraviolet disinfection lamp for irradiation under the condition of no one in the room. The radiation intensity of the ultraviolet disinfection lamp is 12 μw / cm 2 , the irradiation time of the ultraviolet disinfection lamp is 6 hours.

[0023] (2) After the ultraviolet disinfection lamp is irradiated, wrap the blueberries in plastic wrap for storage.

[0024] The principle and effect of this method are the same as in Embodiment 1.

Abstract

The invention discloses a blueberry fresh keeping method utilizing ultraviolet ray irradiation. According to the method, an ultraviolet ray sterilization lamp is used for irradiating picked blueberries, the radiation intensity of the ultraviolet ray sterilization lamp is 5 to 12 muw / cm<2>, and the irradiation time of the ultraviolet ray sterilization lamp is 6 to 12 hours. The blueberry fresh keeping method utilizing ultraviolet ray irradiation has the advantages that the requirement on equipment is low, the mouth feeling of fruit is not influenced, no residue is left, the nutrition ingredients of the fruit are maintained, in addition, the operation is simple, and the implementation is easy.

Description

technical field [0001] The invention relates to a fresh-keeping method for blueberries, in particular to a fresh-keeping method for blueberries utilizing ultraviolet radiation. Background technique [0002] The temperature of blueberries is very high during the ripening period. The respiration of blueberries after picking is strong, various physiological metabolisms are accelerated, and the fruits lose water quickly and are easy to rot. In the current technology, the low-temperature preservation method adopted has a short preservation time and affects the appearance and taste of the fruit; and the chemical preservation method adopted is easy to leave chemical substances, which affects the nutritional content of the fruit. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the purpose of the present invention is to provide a blueberry fresh-keeping method utilizing ultraviolet irradiation for long fresh-keeping time, good taste and no re...
