Organic acid profiles in the juice of fig fruits

To elucidate the organic acid composition and content of fig (Ficus carica L.), a gas chromatography was performed for juices of 20 fig varieties. Acetic, butyric, oxalic, malonic, succinic, fumaric, malic and citric acids wee consistently detected throughout fruit growth. Citric acid was predominant, followed by malic acid. Propionic and lactic acids were not detected. Glyoxylic and tartaric acids were detected only in some varieties and in certain stages of fruit growth. Furthermore, a relationship between the titratable acidity and the organic acid composition was discussed
