Chemical changes and antioxidant activity in pomegranate arils during fruit development.

摘要: Abstract The present research work describes the major chemical changes and antioxidant activity their significance during development of pomegranates. Pomegranate arils showed a significant (P ⩽ 0.05) increase in total soluble solids, sugar reducing contents up to 100 days fruit development, followed by steady-state rate accumulation. highest anthocyanin pigment content (138 mg/100 g) was observed day-old fruit. Significant decreases, 76.2% 71.1% concentration ascorbic acid phenolics, respectively, were recorded from 20 development. equilibrium these chemicals on 100th day marked attainment optimum maturity onset ripening pomegranate After an initial rapid decrease (by 66.9%) protein content, 58.7%) late-developmental stages (80–120 days). high (71.2%) decreased significantly 13%) 60 days, concomitant with phenolics 68.4% 63.9%, respectively. An 10.6% stage due build anthocyanins. trend accumulation depletion above mentioned different ripening. A (9.3%) onwards, as well acidity found be factor for increased incidence internal browning over-ripe fruits.
