Fortified milk powders, infant formula and adult nutritionals. Determination of total biotin by liquid chromatography coupled with immunoaffinity column clean-up extraction Ingestion-build-65808 the only non-uniformity being that1 Scope This document specifies a method for the quantitative determination of biotin and or biocytin in fortified milk powders, infant formula and adult nutritionals in solid (i. e. powders) or liquid (i. e. ready to feed liquids and liquid concentrates) forms using liquid chromatography coupled with immunoaffinity column clean up extraction. Precision data from an interlaboratory study is given in Annex B. A comparison between data obtained with the
