Sake pasteurization using a novel continuous flow pulsed electric reactor with cooling system

A pulsed electric field (PEF) reactor that has two flow paths separated by a membrane was constructed for sake pasteurization. The treatment and cooling solutions were supplied to the in contact with ground electrode high-voltage electrode, respectively. characteristics of microbial inactivation continuous operation novel PEF investigated using NaCl solution containing Escherichia coli as model solution. effects rate on efficiency temperature investigated. In at different rates, lower could achieve effective inactivation, temperatures after almost same. Increasing preventing increase during treatment, but remained around 28 °C when increased. electrical conductivity also It demonstrated increasing increased not only determining appropriate is essential Finally, pasteurization obtained demonstrated. yeast Lactobacillus homohiochii fully inactivated maintained below 40 °C.
