ABSTRACT:
A process is provided for sanitizing fresh foods and beverage products using multiple stages of exposure to different wavelengths of ultraviolet, near infrared and infrared light. A food or beverage product is exposed to ultraviolet light at germicidal wavelengths in order to inactivate undesirable microorganisms on the product. The exposure to ultraviolet light causes damage to the organoleptic qualities product which are subsequently restored by photoreactivation upon exposure of the product to a source of polychromatic near infrared light. In addition, prior to the inactivation of microorganisms, the food or beverage may be exposed to a source of infrared light in order to inactivate enzymes responsible for decomposition of the product. Apparatus suitable for practicing the process of the present invention is also provided, including specific platform arrangements for sanitizing solid, liquid and fluid food and beverage products.
