Abstract

Recently Light Emitting Diode (LED) technology has been emerging as an exclusively nonthermal and non-chemical treatment for surface disinfection and preservation of solid and liquid food materials, where the technology utilises the unique properties of light to interact with varieties of food. Consequently, light technology using LED of different wavelength offers long life expectancies, robustness, and compactness and can be able to solve the huddles regarding food safety during the production, postharvest, and storage when a food industry has concerned. The methods are seeming to be rapid, efficient and reliable alternatives to improve the quality of food and more effective to increase shelf life of food materials along with good preservation ability which is in contrast with traditional food preservation technologies, and moreover the light technology will affect the stability of inactive microorganisms, spoilage enzymes, nutritional and quality parameters of food. Besides majority of these techniques are to be more environment friendly rather than traditional technologies. This review article emphasise on the application and effectiveness of light technology using LED of different wavelength in food industries.
