Area of Science:

  • Food Science
  • Microbiology

Background:

  • Hurdle technology, a combination of preservation methods, has been empirically used for food preservation.
  • Intelligent application of hurdle technology has increased due to better understanding of preservative factors (e.g., temperature, pH, water activity, redox potential, competitive flora) and their interactions.
  • Recent focus includes microbial physiology and behavior (homeostasis, metabolic exhaustion, stress reactions) during food preservation.

Purpose of the Study:

  • To introduce hurdle technology, its principles, and its application in food preservation.
  • To emphasize the role of microbial homeostasis, metabolic exhaustion, and stress reactions in hurdle technology.
  • To discuss the future prospects of multitarget food preservation.

Main Methods:

  • Review of existing literature on hurdle technology and microbial responses.
