Abstract

Reference materials (RMs) were developed for contaminants such as histamine in canned tuna and benzoic acid in mango juice. The RMs were found homogeneous and stable for at least six (6) months. For the reference value assignment, a candidate higher order method like isotope dillution (ID) technique - Liquid Chromatography-Triple Quadrupole Mass Spectrometry (LCMSMS) was applied. These characterized matrix RMs relevant to food safety issues were also used in PT schemes organized locally to help in the dissemination of measurement traceability to international system (SI) of units.
