Freeze-dried mixed cultures as reference samples in quantitative and qualitative microbiological examinations of food.

Abstract

Two simulated food samples in the form of mixtures of bacteria, freeze-dried in small glass vials, were tested for their suitability as reference materials in food microbiology. Stability and homogeneity of the samples were assessed during a 1 year period when stored at 2-6 degrees C. Samples were examined for aerobic plate counts, coliform counts… (More)
