A Weibullian model for microbial injury and mortality

MG Corradini, M Peleg - International journal of food microbiology, 2007 - Elsevier
A microbial survival curve is constructed by plotting the number of recoverable cells or their
logarithm vs. the exposure time to the hostile agent, be it high or low temperature, a …

Microbial survival curves—the reality of flat “shoulders” and absolute thermal death times

M Peleg - Food Research International, 2000 - Elsevier
Occasionally, experimental survival curves of micro-organisms exposed to a lethal agent
have a flat region and traditionally it has been interpreted as evidence of the existence of a …

Modeling microbial survival during exposure to a lethal agent with varying intensity

M Peleg, CM Penchina - Critical reviews in food science and …, 2000 - Taylor & Francis
Traditionally, the efficacy of preservation and disinfection processes has been assessed on
the basis of the assumption that microbial mortality follows a first-order kinetic. However, as …

On calculating sterility in thermal and non-thermal preservation methods

M Peleg - Food Research International, 1999 - Elsevier
There is growing evidence that the mortality of microbial cells, and the inactivation of
bacterial spores, exposed to a hostile environment need not follow a first order kinetics …

Reinterpretation of microbial survival curves

M Peleg, MB Cole - Critical Reviews in Food Science, 1998 - Taylor & Francis
The heat inactivation of microbial spores and the mortality of vegetative cells exposed to
heat or a hostile environment have been traditionally assumed to be governed by first-order …

On the use of the Weibull model to describe thermal inactivation of microbial vegetative cells

MAJS van Boekel - International journal of food microbiology, 2002 - Elsevier
This paper evaluates the applicability of the Weibull model to describe thermal inactivation
of microbial vegetative cells as an alternative for the classical Bigelow model of first-order …

Prediction of an organism's inactivation patterns from three single survival ratios determined at the end of three non-isothermal heat treatments

MG Corradini, MD Normand, M Peleg - International Journal of Food …, 2008 - Elsevier
Traditionally, an organism's heat resistance parameters have been determined from a set of
experimental isothermal survival data. Sometimes, however, even approximating an …

Fully probabilistic microbial inactivation models: The Markov chain reconstruction from experimental survival ratios

M Peleg - Food Engineering Reviews, 2023 - Springer
During microbial inactivation by a lethal agent (ignoring damage/injury, recovery from
damage/injury, etc.), an individual spore or cell can be either viable/alive and countable, or …
