Ultraviolet LED Technology for Food Applications from Farms to Kitchens

Alternative opportunities to current practices of food production and processing that are more sophisticated and diverse are being intensively investigated in the last decades, such as Ultraviolet light (UV) irradiation. Recently, Light Emitting Diodes (LEDs), semiconductor diodes capable of producing light through electroluminescence, started emerging as alternative to UV lamps. Visible (blue, green and white) and infrared LEDs became commonplace in many electronics, curing and lighting applications because of extremely high efficiency (up to 80%) and long lifetime around 100,000 hours. The germicidal UVC LEDs operate at wavelengths between 240 nm and 365 nm. The effects of UVC LEDs against bacteria, viruses and fungi already have been demonstrated and reported along with the first applications for disinfection of air, water and surface made for the point of use integration. UVC LEDs are the next wave in the LED revolution that can bring the numerous advantages of UVC disinfection. UVC LEDs based light fixtures will become the driving force behind wider adoption. Potentially UV LEDs can be used for the treatment of beverages, disinfection of food surfaces, packaging and other food contact and non-contact surfaces. . In addition, LEDs are rapidly becoming more efficient and cheaper, hence it is expected that LED technology will become more attractive to the food industry in the near future. This manuscript focuses on LEDs technology and LEDs unique properties and advantages; summarizes the developments and advancement in 4 areas of applications starting from produce production and horticulture, post-harvest and post processing storage, safety and point of use applications. Brings unique advantages of LEDs for foods from farm to kitchensExplores applications and advances in LEDs for horticulture, crops production, postharvest reservation and produce storageInvestigates UV LEDs in food safety INDICE: 1.
