Title: Some methods of quality systems for food laboratories and their current uses

Abstract

Embrapa Food Technology has been validating analytical and bioanalytical methods and using parameters from published international interlaboratory experiments and in-house validation tests to verify validation parameters. However behavior of some quality parameters for laboratories has shown inconsistencies. Therefore, exploratory plots, such as stem-and-leaf, have shown good results when searching for outliers more suitable than those commonly used statistical tests. Moreover, uncertainty over the working range of some methods indicated changes, which mainly depend on the method and matrix. The literature has been changed and updated, and some publications have recognized that much research has to be developed in many cases. However, further attention has to be paid to validation parameters, especially regarding data characteristics, statistical methods, and matrices.
