Foodstuffs - Simultaneous determination of nine sweeteners by high performance liquid chromatography and evaporative light scattering detection

Asnjë informacion i shtuar.

This European Standard specifies a method for the simultaneous determination of nine sweeteners in beverages and canned or bottled fruits by high performance liquid chromatography (HPLC) with evaporative light scattering detection (HPLC-ELSD). This method has been validated in an interlaboratory study via the analysis of spiked samples on the following matrices: - acesulfame-K (ACS-K) (from 38,3 mg/l to 383,5 mg/l) in beverages and (from 38,4 mg/kg to 391,3 mg/kg) in canned fruits; - alitame (ALI) (from 31,1 mg/l to 114,5 mg/l) in beverages and (from 36 mg/kg to 175,2 mg/kg) in canned fruits; - aspartame (ASP) (from 38,1 mg/l to 702 mg/l) in beverages and (from 37,2 mg/kg to 1 120,2 mg/kg) in canned fruits; - cyclamic acid (CYC) (from 28,3 mg/l to 307,2 mg/l) in beverages and (from 27,5 mg/kg to 1 100,6 mg/kg) in canned fruits; - dulcin (DUL) (from 55,0 mg/l to 115,1 mg/l) in beverages and (from 49,8 mg/kg to 172,6 mg/kg) in canned fruits; - neotame (NEO) (from 37,6 mg/l to 115,3 mg/l) in beverages and (from 37,3 mg/kg to 173,7 mg/kg) in canned fruits; - neohesperidine dihydrochalcone (NHDC) (from 31,4 mg/l to 59,3 mg/l) in beverages and (from 35,3 mg/kg to 59,3 mg/kg) in canned fruits; - saccharin (SAC) (from 36,2 mg/l to 87,6 mg/l) in beverages and (from 44,3 mg/kg to 235,3 mg/kg) in canned fruits; - sucralose (SCL) (from 36,8 mg/l to 346,8 mg/l) in beverages and (from 35,3 mg/kg to 462,4 mg/kg) in canned fruits. For further information on the validation results see Annex C. NOTE The method has been fully validated [1] through collaborative trial, according to the IUPAC Harmonised Protocol [2], on analyte-matrix combinations of all nine sweeteners in beverages and canned or bottled fruits.
