Preservation and Shelf Life Extension focuses on the basic principles of ultraviolet light technology as applied in low-UV transmittance treatments of food fluids and solid foods. It describes the features of UV light absorption in food fluids and available commercial systems, and provides case studies for UV treatment of fresh juices, dairy products, wines, and beer. The book also includes information on various continuous and pulsed UV sources and processing systems, as well as examples of specific treatments for fruits, vegetables, meat and poultry products.

Key Features

  • Addresses preservation and shelf-life extension of foods and food plant safety improvement
  • Explores non-thermal and non-chemical alternatives for preservation and shelf-life extension of fluid foods, drinks and beverages, and for solid foods
  • Written by an internationally recognized expert in ultraviolet light, high hydrostatic pressure processing, and microwave heating


Professionals in Food Engineering, Food Processing, Product Development, and Graduate students
