Summary of the effect of heat treatment on PMI enzymatic activity

Treatment PMI activity units (µmol/min/ml) % Activity of control
Unheated control solution 219 NA
Test solution heated to 25 °C 220 101
Test solution heated to 50 °C 272 124
Test solution heated to 75 °C 0 0
Test solution heated to 95 °C 0 0

Prior to heat treatment, all treatments were solubilized to a target concentration of 1 mg PMI/ml and diluted. The unheated control solution was maintained chilled (on wet ice). Not applicable (NA).
