Abstract:
Organic acids of orange peel and juice were quantitatively determined by gas-liquid chromatography (GLC) with and without purification by eluting through Dowex exchange resin columns (6.0 and 13.25 N formic acid) or by fractionation with petroleum ether, at pH 3.6 or 7.5. Satisfactory recovery and resolution, were usually obtained without purification. Under our conditions elution with 6.0 N; formic acid gave low yields. Succinic*, adipic*, malic, citric, malonic, and oxalic acids were detected both in juice and peel (flavedo). In addition, juice contained of α-ketoglutaric, aconitic, and isocitric acids, while flavedo contained lactic* and benzoic* acids. Acids marked by asterisks had not yet been reported in flavedo tissues; α-ketoglutaric acid had not yet reported in orange juice.
