Abstract
Durian (Durio zibethinus) cvs. Chanee and Monthong fruit were severed from the tree during 14day intervals, from 10weeks after anthesis until commercial maturity. We determined the pulp (i.e. aril; fruit flesh) carotenoid composition, together with pulp firmness, color and total soluble solids (TSS) and postharvest quality. In ripe cv. Chanee fruit the main carotenoids were β-carotene (about 80%), and α-carotene (20%), with minor levels of lutein and zeaxanthin. In ripe fruit total carotenoid concentration (expressed per gram FW) was about 9-fold higher in cv. Chanee than in cv. Monthong. Large differences between the cultivars were also found in β-carotene levels (about 11 times more in cv. Chanee), and even larger ones in those of α-carotene. Differences in lutein and zeaxanthin concentrations were small. Pulp color was deeper yellow in cv. Chanee than in cv. Monthong, which was correlated with α-carotene and β-carotene concentrations. Durian contains a high fat percentage, which is conducive to carotenoid uptake. It is concluded that it is advisable to consume cv. Chanee rather than cv. Monthong if intake of carotenoids is considered important.
