visuals scientific posters - 1

Objectives and Conclusions

The objective is to validate one rapid detection method of spoilage microorganisms, including molds, yeasts, lactic acid and acetic acid bacteria in low pH fruit juice ingredients.

The bioMérieux method D-COUNT® 50 based on Flow Cytometry technology, allowed a significant reduction of time to results from 6 days to 3 days providing valid and equivalent results to the reference cultural method (International Fruit and Vegetable Juice Association IFU 2 C).

The different factors evaluated in one real industrial laboratory (laboratory technician, enrichment incubation time, sample size and storage enrichment broth) did not impacted in the performance characteristics of the method.
