Development of pulsed UV light processes for surface fungal disinfection of fresh fruits.

Pulsed UV (PUV) power techniques were studied as a nonthermal, residue-free alternative to contact pesticides and to evaluate the surface disinfection of fresh fruits using this type of extremely rapid, high-peak power UV beams. Coherent 248-nm beams from excimer lasers were used to simulate a variety of pulsed light sources now commercially available. Surface disinfection on a series of fresh fruits (i.

Use of pulsed ultraviolet laser light for the cold pasteurization of bovine milk.

Because of concerns that some potentially dangerous microorganisms may survive conventional heat pasteurization of milk and because the heat needed to sterilize milk affects marketability, the ability to efficiently cold pasteurized milk may become more desirable. In this pilot study, we investigated the use of pulsed ultraviolet (PUV) laser light to nonthermally (cold) pasteurized bovine milk. Dairy bulk tank milk was treated with UV light (248 nm) emitted from a pulsed excimer laser.

Radiation Processing of Foods: An Overview of Scientific Principles and Current Status.

Despite its scientific and technical label of worldwide approval, acceptance and use of food irradiation in the U.S. has become stagnant and a political and psychological issue.
