The study evaluated the bioactive constituents and physical properties of fourteen pomegranate genotypes grown in the subtropical region of Florida. Variations were found in aril color, total anthocyanin content, and total phenolic content among the different genotypes. Peel tissues had higher total phenolic compounds and reducing power activity compared to pomegranate juice, and reducing power activity was positively correlated with total anthocyanin content.
The global demand for pomegranate has led to increasing research and improvement of cultivars that produce higher antioxidant compounds. The current study was carried out to evaluate the bioactive constituents and physical properties of fourteen pomegranate genotypes grown in the subtropical region of Florida. There were differences in aril color among genotypes. The highest total anthocyanin content was found in 'Ariana', 'Molla Nepes', and 'Parfianka' genotypes. Furthermore, total anthocyanin content in peel ranged from 2.14 to 10.86 mg/100 g dry weight. Total phenolic content in the pomegranate fruit juice differed significantly among genotypes, varying from 365.71 to 1167.40 mg/L. Moreover, total phenolic content in the fruit peel ranged from 1313.08 to 1700.07 mg/L. Total phenolic compounds and reducing power activity in peel tissues were greater than in pomegranate juice. Reducing power activity and titratable acidity were positively and significantly correlated with total anthocyanin content.
