Single-laboratory validation study of determination of patulin by GC-MS in juice

Abstract

We examined whether the analytical method of patulin（a mycotoxin found in fruit juice）developed in Nagano prefecture meets the criteria in the Codex Procedural Manual and Guidelines on Analytical Terminology. The trueness, repeatability, within-laboratory reproducibility and HorRat value were 98.8-103.4％, less than 6.4, 8.1 and 0.4％, respectively, for apple juice and pear juice．Thus, the trueness and precision met the required criteria．.
