Sym’Previus is a decision support software tool for predicting bacterial growth, growth/no growth boundaries and thermal inactivation. It also contains microbiological data fitting tools. The software makes it possible to take into account variability inherent to food products, processes and micro-organisms, as indicated in EC Regulation 2073-2005.

Sym’Previus is available online in both a free and a Premium version. The free version allows the use of the fitting tools while the Premium version (130€/year HT) also allows the use of the simulation tools. Note that all your results and settings are saved in your private user account, which ensures data confidentiality.
