New Rapid Method: Detection of Osmotolerant and/or Osmophilic Yeasts in Just Six Days
Starting September 15, 2025, the BAV Institute will offer a new accredited rapid method for the detection of osmotolerant and/or osmophilic yeasts. Qualitative results will be available in just six days, reducing the previous examination duration by four days.
Background
Osmotolerant and osmophilic yeasts can proliferate in sugary and low-water-content foods. For manufacturers of, for example, confectionery, fine bakery products, delicacies, and beverages, these microorganisms are a central topic of quality assurance. Accelerated detection helps companies identify risks early and quickly implement measures.
Advantages of the New Method
Results in six instead of ten days
Accredited, reliable test procedures
Identification of yeasts directly via MALDI-TOF
Germ count determinations remain unchanged at five days
Overview of Examination Methods
In addition to the new rapid method for yeasts, the BAV Institute uses a wide range of modern procedures to reliably address microbiological questions.
