Characterization of twenty pomegranate (Punica granatum L.) cultivars grown in Spain: Aptitudes for fresh consumption and processing

Spain is the main European pomegranate producer. Depending on the characteristics and composition, pomegranate fruits may be intended for fresh consumption, industrial processing or medicinal purposes. Therefore, is important to evaluate the variability of different pomegranate cultivars to gain more knowledge about the potential of these fruits. In terms of physicochemical and functional parameters in pomegranate arils, the highest values and concentration were: crude fiber, 2.85% (BA1); potassium,. 1.19 g 100 g(-1) dry weight (PTO5); total sugars, 15.9 and 15.5 g 100 mL(-1) (SM and VA1 respectively); total acids, 4.89 g 100 mL(-1) (SM); total polyphenol content, 1791 mg GAE 100 g(-1) dry weight (BBE1); ABTS, 4.24 mmol Trolox kg(-1) fresh weight (MEC); DPPH, 7.74 mmol Trolox kg(-1) fresh weight (MO6); seed hardness score, 7.0 (BA1 and BBE1), aril color, intensity 7.0 (WOND and SM) and sensorial score, 3.0 (ME12, MEM, MEC). Significant differences were found among pomegranate cultivars: soft seeds and high sweetness are optimal for fresh consumption; an intense red color and hard seed are optimal for juice processing; high total polyphenol content, antioxidant activity, crude fiber and minerals can be used as a functional food. Pomegranate cultivars can be considered as a source of fiber and natural antioxidants to develop functional foods. (C) 2017 Elsevier B.V. All rights reserved.
