Provitamin A carotenoid content of different cultivars of edible pandanus fruit

As part of an overall study to identify vitamin A-rich foods, a study was carried out in the Federated States of Micronesia (FSM) to provide information on production, acquisition, consumption and cultural acceptability of edible pandanus cultivars, Pandanus teetorius, and to identify their carotenoid content. Samples of five pandanus cultivars were collected and analyzed for alpha- and beta-carotene by HPLC. The results showed that the two cultivars with yellow fruit coloration contained low levels of carotenoids, while the orange fruits, which were also well liked as a food in the community, contained higher levels at maxima of 190 mug/100 g and 393 mug/100 g for alpha- and beta-carotene, respectively. Common patterns of intake when the fruit is available show that pandanus can provide a large proportion of estimated requirements of retinol equivalents. Local people were generally unaware that pandanus had health benefits, although the food was very popular. Nevertheless, key informants report that production had greatly decreased in recent years. To reverse this trend, those acceptable cultivars high in carotenoid content should be promoted both for their general enjoyment and their health benefits. (C) 2003 Elsevier Science Ltd.
