It has become the hotspot in the area of postharvest vegetables preservation. It could mainly be divid- ed into three categories: LED preservation, UV preservation and radiation preserva- tion. This paper systematically reviewed the mechanisms of different preservation technology of light control, summarized the research progress of light-controlled tech- nology in the physiological characteristics regulation, maintenance of nutritional quali- ty and microbial control of postharvest vegetables at home and aborad, and prospected the further studies on preservation technology for postharvest vegetables.展开更多
