Aseptic Processing of Foods

Aseptic food processing has become important as a safe and effective method for the preparing and packaging of a variety of foods. This recent book, prepared by a team of European specialists, provides a detailed guide and reference to aseptic food processing technology. All aspects are presented systematically: principles, practice, equipment, applications, packages and packaging, quality control, and safety. All applicable food and beverage categories are examined. More than 130 photographs, diagrams, and other schematics illustrate equipment and their function and a variety of procedures. Tables and graphs provide important quantitative data in convenient form.
