Changes in some free sugars and phenolic contents of pomegranate fruits (Punica granatum L.) in three development stages

Gozlekci S., Kafkas E., Ercisli S.

In this study, some free sugars and phenolic contents at three development stages (immature, unripe and full ripe) of pomegranate cv. Hicaznar fruits grown in Antalya, Turkey were determined. While total sugar contents showed a regular increment, total phenol content decreased from the immature fruit to full ripe fruit. The predominant sugars quantified were fructose and glucose, while sucrose was minor sugar in all development stages. Fructose contents in immature fruits to mature fruits varied from 3.53 to 5.78 g per 100g fresh weight basis, while glucose contents varied from 3.44 to 6.37 g per 100g fresh weight. On the other hand, sucrose contents varied from 0.21 to 0.41 g per 100g fresh weight. On the contrary to sugars, the lowest levels of total phenolics and flavanoids were determined in full ripe fruits. Results indicate that both free sugars and phenolic contents of pomegranate were strongly influenced by development stages.
