Dry Heat Inactivation of Bacillus subtilis var. niger Spores as a Function of Relative Humidity

AUTOR(ES)
RESUMO

Dry heat sterilization of Bacillus subtilis var. niger spores at 105 C is enhanced in the relative humidity range 0.03 to 0.2%. D-values of 115 and 125 C are predicted by a kinetic model with parameters set from 105 C data. These predictions are compared to observations.
