My question is focalized on microbiological safety.
I would refer to a predictive scheme base, discriminating food for
composition (milk, egg et.). By monitoring parameters such as water
activity, pH, total viewble count etc.
We do for example brioches (pan of Spain) with or without additive and with
plastic packaging (without modified atmosphere).
