Problems solved by technology

[0003] As plant products, the taste and texture of fruits and vegetables will obviously deteriorate after long-term storage. This is caused by dehydration on the one hand, and on the other hand, it is often difficult for plants to receive sufficient light to maintain photosynthesis during storage.
Because plants will continue to decompose their own starch and other sugars and other nutrients under the action of respiration, which will reduce the quality of vegetables and fruits during storage.
For the dehydration of plants, we can solve the problem by adjusting the ambient humidity of the vegetable and fruit storage room or refrigeration equipment, but it is difficult to solve the problem of plants lacking reasonable light for photosynthesis

Embodiment 1

[0019] The method for keeping vegetables and fruits fresh based on LED pulsed light in the present invention uses a spectrum controller to regulate the wavelength of the excitation light wave of the LED luminous body, and controls the flickering frequency of the LED luminous body; Light, blue light, violet light and far ultraviolet light flash 100 times in total, 0.02 seconds each time, and then pause for 2 seconds; the second stage emits red light and blue light at the same time, flashing 100 times in total, 0.01 seconds each time, and then pause for 1 second; The third stage emits red light, flashes 100 times, each time 0.03 seconds; the fourth stage emits blue light, flashes 50 times, each time 0.03 seconds; pause for 3 seconds after the end of the entire light cycle, and then repeat the cycle of S1, S2, S3, The luminescent step of S4; the luminescent step also includes the use of near ultraviolet light for half an hour every day. The wavelength of red light emitted by the ...

Abstract

The invention provides a vegetable-fruit preservation method based on LED pulsed light. The wave length of light waves motivated from an LED luminous body is adjusted and controlled through a spectrum controller, and the flickering frequency of the LED luminous body is controlled through the spectrum controller. The refreshing time of vegetables and fruits can be greatly prolonged through the setting of the spectrum and a reasonable irradiating period, and the vegetables and the fruits accordingly recover metabolism and keep low speed growing in the light-signal light environment; the vegetables and the fruits keep in the fresh state in the light-signal light environment, the fresh state of the harvested vegetables and the harvested fruits can be effectively prolonged accordingly, and the aims of keeping freshness and delaying taste reduction of the stored vegetables and the stored fruits are achieved.

Description

technical field [0001] The invention relates to a method for keeping fruits and vegetables fresh by using optical signals, in particular to a method for keeping fruits and vegetables fresh based on LED pulsed light. Background technique [0002] With the continuous improvement of people's material living standards, people have put forward higher requirements for the freshness of vegetables and fruits. As we all know, vegetables and fruits are rich in a variety of nutrients that are beneficial to human health. Generally, a large amount of chlorophyll is distributed on the surface of vegetables and fruits to facilitate photosynthesis. Even the fruits of plants may not necessarily appear as Green, but also contains a certain amount of chlorophyll, and also has a certain photosynthetic ability. [0003] As plant products, the taste and texture of fruits and vegetables will obviously deteriorate after long-term storage. On the one hand, this is caused by dehydration, and on the ...
