Methodology guides our work
Baker’s yeast is considered a fresh, viable product with a definite shelf life.
Yeast quality and storability are determined therefore by clean handling and ruling out the presence of microbiological contaminants.
VH Berlin refers to standard identification and enumeration methods, to check contaminants, adhering to the “General characteristics of Baker’s yeast, fresh and dry, published by the COFALEC.
We employ classical, selective, plate techniques for counts and participate in lab test comparisons. Together with partner labs we can also isolate and identify contaminants .
We also supply pure culture fermentations and conduct hygiene tests.
