Carotenoid composition of two Brazilian genotypes of acerola (Malpighia punicifolia L.) from two harvests

Acerola fruit is native to Central America and adapted very well to Brazil, which in turn became the major worldwide acerola producer, consumer and exporter. Two acerola genotypes were harvested from a Brazilian plantation during the 2003 and 2004 summer harvests. Both genotypes presented beta-carotene (265.5-1669.4 mu g/100 g), lutein (37.6-100.7 mu g/100 g), beta-cryptoxanthin (16.3-56.5 mu g/100 g) and alpha-carotene (7.8-59.3 mu g/100 g) as the major carotenoids. In both harvests, the beta-carotene, beta-cryptoxanthin and alpha-carotene levels were higher in the Olivier genotype, whereas the lutein content was higher in the Waldy Cati 30 genotype. Due to higher sunlight exposure, the fruits harvested in 2004 showed higher total carotenoid contents than those from the 2003 harvest. Acerola, especially the Olivier genotype, with 148-283 RE/100 g, can be considered as a good source of provitamin A. (c) 2005 Elsevier Ltd. All rights reserved.
