Research Abstract |
Microbicidal mechanism of carbon dioxide micro-and nano-bubbles at a lower pressure (MNB-CO_2) were investigated and Hiochi bacteria and enzymes in unpasteurized sake were inactivated by the MNB-CO_2. There were no phenomena that Sachharomyces cerevisiae cells were burst by the MNB-CO_2, although the leakage of intracellular matrix was observed. Hiochi bacteria in unpasteurized sake could not be detected and α-amylase, glucoamylase and acid carboxypeptidase be completely inactivated by the MNB-CO_2.
