Examining engineering, microbiology, and statistical challenges in the quest for aseptic processing of particulate foods.
The emerging technology of aseptic processing of particulate foods promises lower packaging costs and higher food quality and safety. The process, however, has yet to be regulated, and the majority of the innovative research performed in the past decade remains uncollected. Aseptic Processing of Foods Containing Solid Particulates fills this void, providing industry professionals and students with a reference on how the continuous sterilization of particulate foods may be accomplished.
Specific topics covered include:
- Flow and residence time distributions of solid-liquid mixtures
- Detailed and comprehensive coverage of the three key aspects of this technology: engineering, microbiology, and statistics
- Fluid-solid convective heat transfer
- Statistical design and analysis and microbiological validation
- Hazard analysis and critical control point evaluation of a multiphase food product aseptic system
- The filing process for FDA approval
- List of symbols included at the end of each chapter
