Descrição

The thermal inactivation characteristics of dehydrated a-amylase in solid state at various moisture contents was studied at temperatures between 135 and 150°C. The inactivation kinetics show a first order decay. The enzyme was found to be more thermostable than in aqueous solution. The z-value dependency with moisture content has shown some fluctuactions, having an absolut minimum of 19°C at 23.9% moisture.
