Sym'Previus is a decision making tool based on predictive microbiology. These tools are available on-line by simply taking out a subscription to the operational cell.
The complementarity of these modules provides numerous simulation options:
 

1) Probabilistic module

Evaluates consumer exposure to microbial dangers during a product's shelf-life. This approach integrates the specific variables related to the product and its production site to provide a personalised result.  

Start module
Demo coming soon

2) HACCP assistance: Identification of microbiological dangers

Analyses the behaviour of 14 bacteria species simultaneously during a procedure. This model identifies the critical species that should be used to determine product shelf life.

 Coming soon

3) Growth interfaces

Simulates the influence of various factors (pH, aw, temperature) on bacterial growth of pathogens and spoilage species. This model produces growth isoprobability graph defining growth / no growth boundary.

Demo in french

4) Growth simulation

Simulates growth taking into account foodstuff, temperature, pH, aw and bacterial characteristics. These factors may be constant or variable over time (cold chain failure, acidification, etc.).

 Start module
Demo coming soon

5) Growth curve fitting

This module calculates typical characteristics for your foodstuff which are then used to simulate microbial growth under various conditions.

Demo in french

6) Thermal destruction simulation

Evaluates the effectiveness of a thermal profile for bacterial destruction for many bacterial species. This model calculates the rate of reduction at the end of a treatment and the probability of a bacteria to survive.

 Start module
Demo coming soon

7) Bacterial survival simulation

 Simulates the regression of a bacterial species when the foodstuff is no longer favourable to its growth (e.g.: Fermented products, salt cured...). The module estimates the time required to inhibit contaminating bacterial species.

 Coming soon

8) Database

 This database contains growth, survival and thermal destruction kinetics obtained in foodstuffs for main pathogens and spoilage microorganisms.
