UV light is one of a number of emerging non-thermal food processing technologies that can be used in a broad range of applications producing food products with longer shelf-life, more safe, and with higher nutritional quality. The new edition of Ultraviolet Light in Food Technology: Principles and Applications will present recent understanding of the fundamentals of UV light along with new applied knowledge that has accumulated during the 7 years since the first edition published in 2009. The new edition of the book will have 11 chapters including 2 new chapters--on chemical destruction with UV light and food plant safety—along with 6 chapters greatly expanded and updated.

Ultraviolet LED Technology for Food Applications: From Farms to Kitchens examines the next wave in the LED revolution and its ability to bring numerous advantages of UVC disinfection. As UVC LED-based light fixtures will become the driving force behind wider adoption, with potential use in the treatment of beverages, disinfection of food surfaces, packaging and other food contact and non-contact surfaces, this book presents the latest information, including LEDs unique properties and advantages and the developments and advances made in four areas of application, including produce production and horticulture, post-harvest and post processing storage, safety and point-of-use applications. Alternative opportunities to current practices of food production and processing that are more sophisticated and diverse are being intensively investigated in recent decades, things like Ultraviolet light (UV) irradiation. The effects of UVC LEDs against bacteria, viruses and fungi already have been demonstrated and reported, along with the first applications for disinfection of air, water and surface made for the "point-of-use" integration. - Brings unique advantages of LEDs for foods from farm to kitchens - Explores applications and advances in LEDs for horticulture, crops production, postharvest reservation and produce storage - Investigates UV LEDs in food safety

The production of environmentally friendly, sustainable, chemical-free food continues to challenge the food industry, spurring on investigations into alternative food processing techniques that are more sophisticated and diverse than current practices. Exploring one of these emerging solutions, Ultraviolet Light in Food Technology: Principles and Applications incorporates the fundamentals of continuous and pulsed UV light generation and propagation; current food regulations; recommendations for optimal UV reactor design, selection, and validation; information on both commercially available and under-development UV sources; and the outlook for future food applications. After reviewing essential terms, definitions, and current applications, the book emphasizes the need to properly assess the physical and chemical properties in foods that influence the effectiveness of UV treatment and impact inactivation kinetics. It also addresses the effects of UV processing on food quality, before considering the engineering aspects of UV light treatment, such as transport phenomena, process calculations, and continuous-flow reactor geometries. The book then describes the principles of validating UV reactors as well as the principles and applications of UV pulsed light, including microbial inactivation in water, meat, fruits, vegetables, and packaging materials. For anyone working in food research, development, and operations, this resource provides broad, accessible information on the science and applications of UV light technology. It shows how UV light irradiation can be used as a physical preservation method in food processing.
