适用范围：This European Standard specifies a method for the determination of the mass fraction of d-biotin by highperformance liquid chromatography (HPLC). The method has been validated in an inter-laboratory test onfortified and non-fortifed samples such as cereal breakfast powder, infant milk powder, lyophilized green peaswith ham, lyophilized chicken soup and on nutritive orange juice, at levels from 16 pg/100 g to 200 pg/100 g.For further information on the validation data, see Annex B.NOTE 1 d-biocytin can also be estimated by this method. But none of the samples used for the validation stepcontained d-biocytin. Nonetheless the recovery rate is more than 90 % for d-biotin and d-biocytin, see [2] and [3].NOTE 2 The method underestimates the real biotin content when used for samples containing egg.
