Abstract: Effect of low-pressure carbonation (LPC) on heat inactivation of Saccharomyces cerevisiae was investigated. The cell suspension was carbonated at 1 MPa and 4 °C for 15 min and subsequently heated from 51 to 61 °C and 5 s to 5 min (heating with LPC). As a control experiment, cell suspension was heat-treated under atmospheric pressure without LPC (heating). The inactivation ratio of heating at 53 °C and 55 °C for 1 min with LPC was approximately 1 log order higher than heating alone. Extending heating time to 5 …
