Briefly, 25 g of
carrots or jams were homogenized with distilledwater (1:4, w/v) in
a blender. The filtered solution was diluted and analyzed by ion
chromatography (Dionex model DX120; Dionex Corporation, Sunnyvale,
CA) with a conductivity detector, using an IonPac CG12A
pre-column and an IonPac CS12A separation column.
