Notes:
Heat, high hydrostatic pressure (HHP) and high pulsed electric field (PEF) inactivations of Zygosaccharomyces bailii ascospores and vegetative cells suspended in apple, orange, pineapple, cranberry and grape juices were investigated. The ascospores exhibited a heat resistance that was more than 5–8 times greater than the vegetative cells. After 5 min of pressurization at 300 MPa, the population of vegetative cells decreased almost 5 log cycles, while the population of ascospores decreased between 0.5-1 log cycles. In each fruit juice studied, two pulses of 32–36.5 kV/cm decreased the population of vegetative cells or ascospores 3.5 to 5 log cycles.
