Actinic process for cold pasteurization of fresh foods and beverages
First Claim
1. A process for sanitizing food products, the process comprising:
- exposing a food product to infrared light in order to inactivate enzymes in the food product responsible for decomposition;
exposing the infrared exposed food product to ultraviolet light at germicidal wavelengths in order to inactivate undesirable microorganisms in the food product, whereby the exposing of the food product to the ultraviolet light causes a reduction in organoleptic qualities of edible portions of the food product; and
exposing the ultraviolet exposed food product to near infrared light in order to restore the organoleptic qualities of the ultraviolet exposed food product.

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.
