The new edition incorporates computational techniques using the personal
computer to solve processing problems encountered in the modern food
industry. New sections include non-linear curve fitting, energy
associated with food freezing accounting for non-frozen water below the
freezing point, flash evaporation and evaporated cooling, pumps and high
pressure systems applications, effective temperature measurement to
account for radiation, simultaneous conduction, convection and radiation
heat transfer freezing time predictions, reaction kinetics including
acquisition and analysis of reaction rate data and use in process
optimization. Recent advances in the food industry are reflected in new
sections on non-thermal methods for microbial inactivation,
sterilization of fluids containing particulates, non-CFC refrigerants
and their thermodynamic properties, vapor induced puffing for producing
crispy dried or baked food products, and application of supercritical
fluids and extrusion to generate unique food ingredients.
