Book excerpt: As a result of developments in biotechnology, bioengineering, and related sciences, processing of bio-materials and bioproducts has become an area of strategic importance. Written in a textbook style, this book attempts to bring together both the theory and practice of thermal processing of bio-materials. The authors describe the principal techniques such as freezing, chilling, membrane concentration, evaporation, drying, and sterilization and their own research experiences, including degradation of thermo and xerolabile bio- products.
