Abstract

Abstract

A solution Certified Reference Material (CRM) of patulin was developed and has been officially approved with the code of GBW(E)100674. This CRM was prepared by using the gravimetric-volumetric method with solid materials of the patulin purity CRM GBW(E)100673. According to the general and statistical principles for characterization of reference materials in JJF 1343-2012, homogeneity and stability tests were carried out with liquid chromatography. Uncertainty was evaluated in consideration of solid purity, solution preparation, homogeneity, short-term stability, and long-term stability. The certified value of the patulin solution is 100 µg/mL with an expanded uncertainty of 2% (k=2). The atulin solution CRM with a traceable and accurate value can support food safety tests in China.
