4 November 2013 | By François Bourdichon, Corporate Food Safety, Microbiology and Hygiene Manager, Barry Callebaut

Taxonomy and classification of microorganisms are based on criteria that do not always, if ever, fit with the complexity of the microbial world. Commensal, starter, probiotic, pathogen?

Mathematics is everywhere. One might go into the field of biology to avoid numbers and equations, yet they are still there, helping food technologists to decipher the behaviour of micro-organisms in different food matrices and along the process chain. Since the negation of the spontaneous generation theory by Louis Pasteur…
