The Inactivation kinetics of
alpha-glucosidase
, glucoamylase, alpha-amylase, and
acid carboxypeptidase
in fresh sake using a continuous flow system for high-pressure carbonation were investigated. In addition, the effects of ethanol and sugar concentrations on inactivation of the enzymes in high-pressure carbonated sake were investigated. Among the enzymes investigated,
alpha-glucosidase
was the most stable and alpha-amylase was the most labile on inactivation under carbonation. The decimal reduction times (D values) of
alpha-glucosidase
, glucoamylase, alpha-amylase (extrapolated from the Z value), and
acid carboxypeptidase
were 29, 6, 2, and 5 min respectively at 45 degrees C. These values are lower than those subjected to heat treatment. On the carbonation treatment as well as the heat treatment, ethanol accelerated the inactivation of all four enzymes, but glucose depressed the inactivation of these enzymes, except for
acid carboxypeptidase
. These results suggest that this continuous flow system enabled effective inactivation of enzymes in fresh sake.
