Dry-heat inactivation of Bacillus subtilis spores by means of infra-red heating.

Abstract

An experumental equipment for dry-heat inactivation of bacterial spores in an open system using Infrared (IR) radiation for energy transfer was deveoped. The dry-heat-inactivation kinetics for Bacillus subtilis ATCC 6633 spores were studied in the temperature range of 120-180 C. The z value (z = 23C) was constant in the temperature range investigated. The advantages offered by using IR radiation in sterilization systems are pointed out.
