Embodiment 1

[0012] Using LED light emitting devices, combined into a mixed light source, so that the wavelength of red light is 640nm, and the wavelength of green light is 420nm. After mixing according to the intensity ratio of red / green = 6:1, turn on the power and install it in refrigerators, fruit and vegetable storage rooms. In places where fruits and vegetables are stored, comparative testing of vitamins and chlorophyll can be carried out on fruits and vegetables, and the results can be obtained, and the freshness preservation ability has been significantly improved.

Embodiment 2

[0014] Common colored light sources are used to combine into a mixed light source, so that the wavelength of red light is 690nm, the wavelength of green light is 470nm, and the wavelength of blue light is 600nm. After mixing according to the intensity ratio of red / green / blue=10:1:1, then The power supply is installed in places where fruits and vegetables are stored, such as refrigerators and fruit and vegetable storage rooms, and the comparative detection of vitamins and chlorophyll on fruits and vegetables can yield results, and the freshness preservation ability has been significantly improved.

Abstract

A photosynthetic antistaling method for vegetables and fruit features that a light source composed of the LEDs with particular wavelengths for generating the mixture of red, green and blue lights is installed to the position where the vegetable and fruit are stored.

Description

technical field [0001] This patent relates to the technical field of fresh-keeping of fruits and vegetables, and more specifically relates to a method for using a specific light source to promote photosynthesis of fruits and vegetables for fresh-keeping. Background technique [0002] At present, people have been using various fresh-keeping technologies to maintain the freshness of fruits and vegetables, such as removing the ripening gas of fruits and vegetables by means of activated carbon, catalysts, etc., delaying the ripening time of fruits and vegetables to maintain their freshness. These utilization methods are utilization methods for the purpose of removing metabolites of fruits and vegetables. However, there are no reports on using specific light to promote vegetables and fruits to continue to maintain photosynthesis to produce vitamin chlorophyll to maintain freshness in commercial refrigerators or various places for storing fruits and vegetables.
