Abstract：Fresh fruits and vegetables contain a large amount of water and rich nutrients,which are prone to spoilage during transportation and storage,greatly affecting their commercial value.The traditional chemical preservation methods have significant effects,but there are certain safety hazards,and its operation is relatively complex,and thus can no longer meet the growing market demand.LED(light emitting diode)dimming technology,as a new type of green fruit and vege-table preservation and storage technology,has attracted widespread attention in the food industry.It can effectively main-tain the commercial appearance of fruits and vegetables,slow down the decline in post harvest quality,improve the nutri-tional value of fruits and vegetables to a certain extent,and achieve the goal of reducing storage losses and extending the shelf life of fruits and vegetables.This article reviews the impact of LED light modulation technology on the color,appearance,and nutritional quality of fruits and vegetables,as well as its effects on fruit and vegetable metabolism from monitoring the levels of antioxidant system,disease resistance,and enzyme activity.It also looks forward to the current application status and prospects of LED light modulation technology,in order to provide new ideas for innovation in fruit and vegetable preservation technology and industrial development.
