Abstract
Methods and apparatus for food product preservation by inactivation of microorganisms and/or enzymes by applying pulses of very intense, very short duration pulses of light in the visible and near visible frequencies to the surface of food products to be preserved. Also disclosed are packaging methods and apparatus utilizing such intense, short pulses of polychromatic, incoherent light.
Claims8
A method for aseptic packaging of medical devices comprising the steps of
- providing an aseptic packaging material having a sterilized medical device contacting surface intended to form at least part of the interior surface of a sealed medical device container,
- applying to the entire surface of a medical device at least one high intensity polychromatic, incoherent light pulse having a duration in the range of from about 0.001 to about 20 milliseconds, and an energy density at said medical device surface in the range of from about 0.01 to about 50 joules per square centimeter to sterilize the entire surface of the medical device,
- introducing the sterilized medical device into contact with said sterilized medical device contacting surface while excluding microorganisms from contact with said medical device and said sterilized medical device contacting surface,
- and sealing said sterilized medical device contacting surface of said packaging material to form at least part of the interior surface of a sealed medical device container enclosing said sterilized medical device to provide a sealed aseptically packaged medical device product.
