Carotenoid, flavonoid profiles and dietary fiber contents of fruits commonly consumed in Thailand

Abstract

Soluble and insoluble dietary fiber and flavonoid contents in 21 varieties of Thai fruits, as well as carotenoids in five varieties of ripe durians were determined. Fresh fruits were purchased from five local markets in Bangkok during July 2008-May 2009. Dietary fiber content ranged from 0.71 to 3.58 g/100 g edible portion, with all five varieties of durian, guava, ripe banana and papaya being good sources of dietary fiber. Durian (Chanee, Kradom, and Puang manee variety) having yellow to deep-yellow color pulp had the highest carotenoid content. Durian, pomelo, guava and ripe banana were good sources of flavonoids; especially pomelo (Thong dee and Tuptimsayam variety) showed the greatest total flavonoid content (13,994.21 and 15,094.99 μg/100 g edible portion). Data in this study demonstrated that Thai fruits are not only a good source of dietary fiber but also a good source of carotenoids and flavonoids. © 2010 Informa UK Ltd.
