In-Plant Validation Studies are usually considered as a “gold standard” for they provide real-life data of a process efficacy. Data generated from in-plant trials provide food processors with the highest level of scientific robustness, as the tests are performed directly on the process to validate, in its real industrial environment.
Since the use of a pathogenic microorganism in processing facilities is not advised, surrogate microorganisms are used as test organisms for in-plant validation studies. Surrogates are non-pathogenic microorganisms that mimic the resistance of foodborne pathogens under different kinds of stress (heat etc.). Due to their safety, surrogates are used directly at the plant (pilot or industrial), to test the efficacy of microbial kill steps. In order to streamline in-plant process validation studies, Novolyze has developed SurroNov®, the first range of dried, ready-to-use surrogate bacteria.
The compatibility of SurroNov® surrogates has been verified for a wide range of processing technologies, pathogens and food products including:
