Institute of dairy science & probiotics

We perform various microbiological analysis of milk and milk products. We analyse the presence of pathogenic microorganisms, technologically important microorganisms (starter cultures, spoilage bacteria), inhibitory substances. We use both traditional methods and modern microbiological methods (PCR).

The laboratory of Institute of Dairy Science and Probiotics is accredited by Slovenian Accreditation with accreditation number LP-062 in the field of testing (SIST EN ISO/IEC 17025:2017).

Accredited methods are marked with *.
