|Preservation of agricultural products and food commoditiesis a major concern now-a-days. In order to augment this issue, worldwide there are many novel technologies which are under intensive research. Light emitting diode (LED) is an emerging non-thermal technology which is at infant stage and has a great potential for food and agro industry. LED is a semiconductor which emits visible light when an electric current passes through it. A LED can emit light within a very narrow wavelength spectrum and can bring about antibacterial effect in microorganisms. There has been very less research work carried out to explore the potential of the technology in order to inactivate the microorganisms in foods. If proven to inactivate microorganism in food and agro industry, the technology can be successfully applied for increasing the shelf-life of food products and agricultural commodities. So, the authors conducted a research to investigate the inactivation of microbial inactivation by using LED lights in the range 400-480 nm wavelength which damages the DNA of the microbes and observed that 5-log reduction can be obtained. This is a novel technology that overcomes the limitations of other novel technologies and proves beneficial to the food and agro processing sector.|
