Fluoride Working Group Meeting Book (November 15, 2017)

AOAC INTERNATIONAL Stakeholder Panel on Infant Formula & Adult Nutritionals (SPIFAN) AOAC SPIFAN WORKING GROUP ON FLUORIDE

Working Group Chair: Eric Poitevin (Nestlé) • The analytical challenge

– To measure fluoride at very low levels specified in the SMPR requires specific/costly equipment and technique to attain the limit fixed at 5 µg/100g reconstituted product • One option – Considering the Codex limit ( around 65 µg/100 g in reconstituted IF ) and modify the SMPR with a higher LOQ that can be fixed at 20 µg/100g in the reconstituted product (i.e. 3 times over codex limit) – Such an LOQ could be achieved by classical techniques (ISE, IC, Colorimetry,..) used by numerous labs and hence a call for method could be more fruitful.

• Recommendation of SPIFAN? – SPIFAN agreed that the working group reopen to reconsider and modify the SMPR.
