要約(英語): We have been investigating the sterilization of liquid food by high electric field pulse. The sample was Escherichia coli (JM103) in aqueous solution of L-Serine, L-Alanine, L-Histidine, L-Glutamic acid, D-Glutamic acid, L-Aspartic acid, K2HPO4, or KH2PO4. High voltage pulse (-4.40 kV) was applied to the each sample at room temperature. As results, the survival rates of L-Glutamic acid, D-Glutamic acid, L-Aspartic acid, K2HPO4, or KH2PO4 samples greatly decrease with the number of applied pulses. On the other hand, the survival rates of L-Serine, L-Alanine, or L-Histidine samples slightly decrease. The experimental results suggest that the survival rate of E. coli by high electric field pulse sterilization is governed the anions or negative charges in aqueous solution.
