AOAC SPIFAN Stakeholder Panel Meeting Book (March 12, 2020)

Accuracy – NIST SRM 1849a Data (mg/kg)

Conclusion: some elements slightly outside certified limits, including Na and Cu

Accuracy – Spiked Recoveries

(b) Cr, Mo, Se recoveries not determined on malt-based drinks

Conclusion: all recoveries within 90-110% except a low-level Cr. The recovery for Fe in the malt foods was ~80% with a typical powder reconstitution, which is why we employed a double-digestion of a direct weight of powder.
