Kinetics of inactivation ofBacillus subtilis spores by continuous or intermittent ohmic and conventional heating
5 Feb 1999
Abstract excerpt
Bacillus subtilis spores were suspended in 0.1% NaCl solution (ca. 10(7) CFU/mL) and treated by conventional or ohmic heating under identical temperature histories. Temperatures tested were in the range of 88 to 99 degrees C. Survival curves and calculated D values showed significantly higher lethality for spores by ohmic than conventional heating. The z or Ea values corresponding to the two heating methods,...
