S.M.H. Mortazavi, K. Arzani, M. Barzegar
Sugar and organic acid composition of date palm fruit (Phoenix dactylifera L.) cultivar ‘Barhee’ were measured using high performance liquid chromatography (HPLC) during fruit growth and development. According to the results, malic acid was detected as the main organic acid in the first growth stages while succinic acid and acetic acid were main acids detected in the Khalal and Tamar stages respectively. A reduction of total acid was observed until 100 days after full bloom (DAFB), and then dramatically increased during last growth stages (120, 140 and 160 DAFB). In these stages, acetic acid was the main acid increased and reached its maximum. As for the sugars, fructose and glucose were identified as the dominant sugars, and their levels varied remarkably during fruit development. The concentration of sugars was increased continually during fruit development reached its maximum level by 160 DAFB. Sucrose content was practically negligible.
