Comparison of Uncertainty Between Traditional and Alternative Methods for Food Microbiological Analysis

摘要

The objectives highlighted in the present study were to determine the estimates of measurement uncertainty associated with microbiological analysis in food samples performing a gage repeatability and reproducibility study on three different microbiological methods of analysis for the detection and quantification of total coliforms; Plate count method, 3M Petrifilm~(TM) count plates method and the MBS method. For all three methods the contribution the total gage R and R is less than 10%, demonstratingthe ability to accurately evaluate the concentration of total coliforms in food samples. However, the repeatability and reproducibility follows the tendency; Plate count method<3M Petrifilm~(TM) count plates method
