An integrated tertiary model called “GroPIN” was developed by SOPHY partner Agricultural University of Athens using Visual Basic for Applications. The application may serve as a user-friendly and highly transparent predictive modelling database for kinetic (growth or inactivation) and probabilistic models.

It also offers the flexibility of interactive options in selecting the graphical and numerical simulation of models. An unlimited number of mathematical models can be introduced into the database via equation editor, as compared with other applications, where only a limited number of equations is already embedded into the source code which is not updatable or expandable.

The current version of GroPIN has a total of 367 published models for the behaviour of 29 pathogens and 43 spoilage organisms, including spoilage and mycotoxigenic fungi, bacteria and yeasts in various foods of plant (e.g., fresh-cut salads, deli salads, berries, juices, etc.) or animal origin (meat and meat products, dairy products). The impact on microbial behaviour of a variety of critical and commonly encountered intrinsic (preservatives, organic acids in total or undissociate/dissociate form, salt, aw, nitrates, etc.) and extrinsic (temperature, CO2 pressure, anaerobic conditions) factors is accounted for by the models registered in GroPIN up to date. The microbial responses modelled (i.e., dependent variables) include the maximum specific growth rate, the death rate, the lag phase duration, maximum population density, time to X-log reduction/growth, D-values and the probability of growth.
