Ascorbic acid, vitamin A, and mineral composition of banana (Musa sp.) and papaya (Carica papaya) cultivars grown in Hawaii

Abstract

Banana (Musa sp.) and papaya (Carica papaya) cultivars were harvested from different locations throughout Hawaii and analyzed for vitamin C (ascorbic acid), provitamin A (b-carotene, a-carotene, b-cryptoxanthin), and mineral composition. Dwarf Brazilian (‘‘apple’’) bananas had almost three times more vitamin C (12.7mg/100 g fresh weight) than Williams fruit (4.5mg/100 g). Also, Dwarf Brazilian bananas had 96.9 mgb-carotene and 104.9mg a-carotene/100 g, whereas Williams fruit averaged 55.7mg b-carotene and 84.0mg acarotene/100 g. Bananas contained higher concentrations of lutein than of the provitamin A pigments, aand b-carotene. Papaya vitamin C content was 51.2mg/100 g, with no differences among cultivars. Papaya provitamin A carotenoids averaged 232.3 mgb-carotene and 594.3mgb-cryptoxanthin/100 g, and vitamin A ranged from 18.7 to 74.0 mgRAE/100 g. Lycopene was not detected in the yellow-fleshed cultivars, Kapoho, Laie Gold, and Rainbow, but the red-fleshed Sunrise and SunUp fruit contained 1350–3674 mg lycopene/100 g. Dwarf Brazilian bananas had higher P, Ca, Mg, Mn, and Zn contents than Williams fruit. The average K content for Hawaii’s bananas was 330.6mg/100 g. Papayas (100 g) contained 9% of the dietary reference intake (DRI) for Cu, 6–8% of the DRI for Mg, but less than 3% of the DRI for other minerals. r 2006 Elsevier Inc. All rights reserved.
