Abstract: The effect of blue light irradiation on quality of six common fruits and vegetables under 4℃ storage conditions were investigated, and non-blue light irradiation was treated as control. The results showed that with the blue light irradiation, the color and shape of fruits and vegetables was kept, the sensory scores of fruits and vegetables after storage for 7 days was improved, the formation of soluble solids during storage was delayed, the decreasing of vitamin C content of fruits and vegetables was delayed, and the growth of microorganisms on the surface of fruits and vegetables was inhibited. In summary, the blue light irradiation treatment could maintain the quality of fruits and vegetables, which is an effective method of preservation in refrigerator.
