Dr. Gene Bartholomew

This course discusses thermobacteriology as it is applied to food processing. With a focus on the methods of process evaluation, special attention will be given to fundamental concepts on which the development of the methods is based. The course indicates some of the many problems that still exist concerning further refinement in the art of thermal processing of foods.

Benefits and Learning Objectives

Upon completion of this course, we expect trainees to:

  • Appreciate the diversity of microorganisms encountered in foods
  • Grasp the importance of food spoilage and pathogenic microorganisms
  • Understand microbial growth and controlling factors
  • Be familiar with the logarithmic enumeration of microorganisms
  • Understand bacterial response to lethal temperatures
  • Be comfortable with terms used in thermalĀ bacteriology
  • Use models and temperature profiles of foods during heating to estimate detrimental effects on microorganisms
  • Know how to apply the model to different foods and how to locate resources available to practitioners
