title: [Content and bioavailability of carotenoids from peach palm fruit (Bactris gasipaes) as a source of vitamin A].
abstract: Four introductions of ripe peach palm fruit (Bactris gasipaes) were analyzed for ether extract, total carotenoids and their biological conversion into vitamin A. Also, edible portion in cooked fruit was estimated. Ether extract content in raw fruit ranged from 8.2 to 12.9% dry basis (DB), cooked between 5.7 to 12.4% DB and nutrient retention after cooking was 69 to 100%. Carotenoids content in raw and cooked pejibaye was similar, 4.8 to 29.6% DB and 4.8 to 29.9% DB, respectively, giving a nutrient retention after cooking greater than 85%. Average edible portion was 68 +/- 2%. The biological study showed significant differences (p < 0.05) of pejibaye carotenoids efficiency conversion in retinol, the values varied from 14 to 50%. Food efficiency results in the control and experimental diets were not statistically significant (p > 0.05). Carotenoids content was inversely related (r = -0.8, p < 0.02) with ether extract. Cooking had no significant effect in ether extract and carotenoids content, except in one introduction. Based in the results generated in the study and vitamin A Recommended Daily Allowances (RDA) it was estimated that one, in three introductions and seven in the remaining one satisfies an adult RDA's.
