Inorganic anions in Spanish RCM were simultaneously analyzed (Cl-, 3 - 17 mg/kg sugar; HPO42-, 0 - 1 mg/kg sugar; SO42-, 0 - 5.6 mg/kg sugar). Recoveries (%) of the different anions in the studied media vary in the range 96.5 to 102.7. The content of anions in other products (commercial refined sugar and sulfited must) has also been evaluated. Refined sugar has a higher content of anions than RCM, especially oxalate (7.5 mg/kg sugar) and nitrate (4.5 mg/kg sugar). The studied anions occur in sulfited musts at very high concentrations. ER -
