Methods and apparatuses are described for food product preservation by deactivation of microorganisms and enzymes by applying high-intensity, short-duration pulses of polychromatic light in a broad spectrum to packaging material surfaces. A photodiode is employed for detecting the intensity of the light, and a control circuit is used to adjust power delivered to a flashlamp if the intensity of the light needs adjustment. An outer safety glass is employed to protect the flashlamps. The outer safety glass may include coating materials at ends thereof. In addition, several variations of lamp assembly geometries accommodate small diameter packaging material tubes by using an fill pipe having offset first and second portions with a transitional region thereinbetween, or be eliminating the water jackets and using an outer safety glass to contain water as it is passed over flashlamps. A lamp holding device includes a holding cylinder with a first flange, which, together with a compression cylinder, compresses the first O-ring into the flashlamp. A lamp holding device is positioned in a receptacle into which an electrode of a U-lamp is inserted. The lamp holding device allows a proximal portion to move relative to a distal portion thereof. A light guide is positioned to receive light emitted from a linear flashlamp and to transmit such light into a packaging material cup.

Deactivation of microorganisms

Methods and apparatuses are described for food product preservation by deactivation of microorganisms and enzymes by applying high-intensity, short-duration pulses of polychromatic light in a broad spectrum to packaging material surfaces. In some embodiments, a photodiode is employed for detecting the intensity of the light, and a control circuit is used to adjust power delivered to a flashlamp if the intensity of the light needs adjustment. In some embodiments, an outer safety glass is employed to protect the flashlamps. The outer safety glass may include coating materials at ends thereof. In addition, several variations of lamp assembly geometries accommodate small diameter packaging material tubes by, for example, using an fill pipe having offset first and second portions with a transitional region thereinbetween, or be eliminating the water jackets and using an outer safety glass to contain water as it is passed over flashlamps. In another additional embodiment, a lamp holding device includes a holding cylinder with a first flange, which, together with a compression cylinder, compresses the first O-ring into the flashlamp. In yet another embodiment, a lamp holding device is positioned in a receptacle into which an electrode of a U-lamp is inserted. The lamp holding device allows a proximal portion to move relative to a distal portion thereof. In yet a further embodiment, a light guide is positioned to receive light emitted from a linear flashlamp and to transmit such light into a packaging material cup.

The present invention is directed to methods and apparatus for preserving fluid foodstuffs, and more particularly, is directed to such methods and apparatus for extending the shelf life of perishable fluid foodstuffs such as dairy products, fruit juices and liquid egg products, which are growth media for microorganisms. The present invention is also directed to preserved liquid foodstuffs which have extended shelf life.

Methods 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.
