摘要：

Pulsed light (PL) is a technique to decontaminate surfaces by killing microorganisms using pulses of an intense broad spectrum, rich in UV-C light. The present review is focused on the application of PL for food decontamination. It revises the mechanism of microbial inactivation (UV-C as the most important part of the spectrum, photothermal and photochemical mechanisms, inactivation curve, peak power dependence, and photoreactivation), the factors affecting its efficacy, the advantages and problems associated with PL treatment, and results obtained in vitro. Examples of applications to foods are given, including microbial inactivation, and effects on food matrices.
