First BCR-intercomparison on the determination of folates in foodFunded under: FP2-BCR 4
The first BCR intercomparison on the determination of folate in food was designed to study the state of the art in folate analysis in a group of experienced vitamin laboratories in Europe. 15 participants from 8 countries took part using microbiological and HPLC procedures, enzyme protein-binding assays (EPBA) and commercial radioprotein-binding assay kits (RPBA). The participants were asked to quantify folate levels in a lyophilised Brussels sprout material, which had been prepared specifically as a candidate reference material for vitamin work, using their preferred method of analysis. Three types of deconjugation were also investigated: human plasma (HP), chicken pancreas (CP) and hog kidney (HK). Generally good agreement was obtained by participants using the microbiological procedures.
