Description
Technical Field
The invention relates to a refrigerator, in particular to a refrigerator with a light fresh-keeping function.
Background
With the pace of life and the change of consumption habits, many consumers have gradually developed a consumption habit of buying a large amount of food at a supermarket at a time, and in order to prolong the storage time of the food, the food is usually stored in a refrigerator, wherein the storage of fresh fruits and vegetables is the most common.
The fresh fruits and vegetables are still fresh and alive life individuals for a long time after being picked, and when the fruits and vegetables are stored in the refrigerator, the low-temperature environment of the refrigerator can inhibit the respiration of the fruits and vegetables to a certain extent and slow down the metabolism, but the nutrients of the fruits and vegetables are continuously consumed and lost along with the prolonging of the storage time. Therefore, most refrigerator enterprises are dedicated to deep fresh-keeping research on fruits and vegetables to prolong the fresh-keeping period of such foods.
At present, the refrigerator industry converts the light preservation technology into refrigerator products, and the technology is to promote photosynthesis of fruits and vegetables by irradiating the fruits and vegetables with light with specific wavelength to convert absorbed light energy into chemical energy, so as to realize accumulation of photosynthetic substances. Researches show that illumination is a necessary condition for energy source and nutrition synthesis of plant photosynthesis, and illumination is favorable for maintaining fresh color of colored fruits and vegetables for a long time and keeping good quality and commodity of the colored fruits and vegetables.
The light wave bands adopted by the light fresh-keeping technology are three types of red, orange and blue, wherein the red light has the functions of reducing the generation amount of ethylene and inhibiting the decomposition of VC, is beneficial to the synthesis of carbohydrate and improves the stem knot development of plants; the blue light can inhibit the growth of plants and buds, so that the vegetables are stronger. Therefore, the light irradiation of different wavelength bands has different effects for different plants. For fruits and other foods, the red light irradiation is more suitable, so that the ripening acceleration and the decomposition of nutrient components are inhibited; for vegetables and other foods, blue light irradiation is emphasized, so that the vegetable nutrition regulator is beneficial to inhibiting plant metabolism, reducing nutrition loss and ensuring that cells are full.
