Description of Listeria Behaviour Under Various Pressurization Strategies

摘要

The effect of high pressure on Listeria innocua was (partly) quantified and also mathematically described to estimate the contribution of dynamic and structural parameters. With increasing pressure times Listeria were increasingly inactivated following sigmoidal isobars. The lethal effect was referred to pressure build up rate and holding time only when a threshold pressure was surpassed. Selected experimental data were fitted to an adopted Gompertz equation forming a model sufficiently describing the inactivation of the Listeria.
