Accordingly, the type and composition of the buffer used in the microbial testing should be documented when HPP microbial inactivation data is analyzed. Samaranayake et al. (2013) measured pH in situ and reported the results for liquid and semiliquid foods under pressure up to 800 MPa. 60. The measurements showed an increase of acidity in all tested liquid food and water samples with increasing pressure. In general, food samples exhibit a buffering action under pressure resisting changes in pH.

The D-value can be obtained as the negative reciprocal slope of log(N/N0) vs. time t and is reciprocally related to k. 1 presents the examples of generated D- and z-values for the most significant pathogenic organisms of concerns and spoilage organisms. 768 450 Patterson et al. 768 350 Patterson et al. 768 275 Patterson et al. (1995) E. 303 400 T=50°C Gervilla et al. (1997a) E. 92 400 Patterson and Kilpatrick (1998) E. 303 450 T=25°C Gervilla et al. (1997a) E. 92 500 T=50°C Patterson and Kilpatrick (1998) S.

7 After the pioneering work of Bridgman (1931), the properties of water under pressure were well documented. Data are available from the International Association for the Properties of Water and Steam (IAPWS). A software implementation of IAPWS work can be obtained from the US National Institute of Standards and Technology (NIST). Most high moisture foods are assumed to have thermodynamic properties similar to those of water at the pressures and temperatures used in HPP. This assumption is less valid for lower moisture, high solids, and nonuniform systems.
