Microbial growth and survival: developments in predictive modelling.

Author(s) : ROBERTS T. A.


Evaluating the ever-changing ranges of products, processes and storage conditions available, through traditional methods is impossible, and the literature still lacks much information needed to design microbiologically safe and shelf-stable products. "Predictive microbiology" models growth, survival and death responses of key microbes with respect to the main controlling factors (pH, water, temperature, atmosphere, preservatives). Models for the common pathogenic bacteria from a programme funded by the United Kingdom government mimic the microbial responses in a wide range of foods and are available on personal computer software running under Windows. Errors of predictions of validated models are proving no greater than the errors of microbiological experiments. As those in the food industry and in food control gain confidence, modelling will play an important role in maintaining a safe and wholesome food supply.
