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.

An intuitively organized and incisive exploration of UV radiation and its modern applications In Photochemical Reactors: Theory, Methods, and Applications of Ultraviolet Radiation, distinguished civil engineer and researcher Dr. Ernest R. Blatchley III delivers a comprehensive exploration of the theory, methods, and contemporary and emerging applications of ultraviolet (UV) radiation. The author describes the fundamentals of the history of photochemistry and photochemical reactions before moving on to consider the dynamic behavior of UV-based reactor systems and the physical concepts that govern natural and man-made sources of UV radiation. The book also covers the numerical and empirical methods used to evaluate photochemical kinetics, photobiological kinetics, and the dynamics of UV photoreactors. Common and emerging applications of UV radiation—like the disinfection of water, wastewater, air, and surfaces—are discussed, and UV-induced transformation processes are also explored. Readers will also find: Thorough introductions to methods and principles that are universal to UV processes, as well as comparisons between those processes Critical explorations of the physics of natural and artificial sources of ultraviolet radiation Practical discussions of modern applications of UV radiation, including the disinfection of water, air, wastewater, and surfaces, as well as the use of UV photoreactors to promote photolysis and photo-initiated, radical-mediated reactions Perfect for UV professionals, academics, and scientists, Photochemical Reactors: Theory, Methods, and Applications of Ultraviolet Radiation will also earn a place in the libraries of professionals working in companies that manufacture UV reactors, as well as engineering consultants with a professional interest in ultraviolet radiation.

This book is about the roles and importance of Ultraviolet (UV) light from sun and from man-made UV lamps in our daily life, on health and diseases, also its application in sterilization and treatment. The key words are: reactive oxygen species, DNA damage, UV mutagenicity, skin cancers, polymorphous light eruption, Xeroderma pigmentosum, vitiligo, psoriasis, rheumatoid arthritis, diabetes mellitus, metabolic syndromes, cardiovascular diseases, dermatology, photobiology, photodermatosis, vitamin D synthesis, vitamin D efficiency, water sterilization, blood sterilization, phototherapies, skin tanning and UV dosimeter. The book starts with introduction to UV light and the history of development of UV lamps and its applications. It then moves to describing the interaction of this light with biological components and the production of reactive oxygen species, their roles in cell signaling, cellular defense from foreign invaders, in mutagenesis leading to skin diseases including vitiligo, polymorphous light eruption and various forms of skin cancer. Then it presents the synthesis and importance of UV light and diseases, induced due to the deficiency of vitamin D. Roles of UV light in sterilization, disinfection, phototherapies are depicted in the next part and finally use and abuse of UV light in tanning salon and the availability and importance of use of UV dosimeter are highlighted. The three main focuses of this book are: - Damage to biological systems by UV light leading to certain skin diseases; most importantly skin cancers. - Importance of UV light in the in vivo synthesis of vitamin D when human bodies are exposed to it. - Diseases caused due to the deficiency of vitamin D and the use of UV lamps in phototherapy and sterilization processes. The editor has considerable experience in publishing medical books and has used it critically selecting the matters which will attract the readers from many areas of medical and non-medical fields. It is hoped that the materials presented in this book will give great benefit and will stimulate both novice and expert researchers in the field. The book gives excellent overviews of the current status of research and pointers to the future research achievements. Clinicians, medical general practitioners, technicians and staff working in UV related industries and especially those working in tanning salon should benefit from the information presented in safe handling of this light.
