FOOD SAFETY MAGAZINE - FEV 2019 - Advances in UV-C Light Technology Improve Safety and Quality Attributes of Juices, Beverages, and Milk Products. Beverages | February/March 2019 By Tatiana Koutchma, Ph.D.
The growing consumption of premium categories of dairy, fruit, and vegetable beverages has been attributed to the perceived health benefits of the “all natural,” “made of organic ingredients,” reduced-calories, and reduced-sugar messages based on high levels of enzymes, nutrients, and bioactive constituents. To achieve these attributes, the products have to be minimally processed in terms of treatment temperature and exposure to oxygen. For instance, the growth of the cold-pressed juice industry from local into regional and national markets required higher stability, safety, and extension of product shelf life to at least a few weeks. Thermal pasteurization is an effective preservation technique but often negatively impacts both nutritional and quality parameters.
Ultraviolet-C (UV-C) light is another emerging nonthermal alternative that offers less expensive, energy-saving continuous treatment and packaging flexibility. Milk.

This research studied the kinetics of PL inactivation of microorganisms naturally occurring in some vegetables. Highlights ► Weibull model satisfactorily describes pulsed light inactivation survival curves. ► A single low-energy light pulse yields one log reduction in vegetables. ► Pulsed light efficacy is limited for high residual counts in vegetables.
