COSTA, Tânia da Silveira Agostini et al. Carotenoids composition of canistel (Pouteria campechiana (Kunth) Baehni). Rev. Bras. Frutic. [online]. 2010, vol.32, n.3, pp.903-906. Epub Sep 03, 2010. ISSN 0100-2945. http://dx.doi.org/10.1590/S0100-29452010005000083.
Canistel (Pouteria campechiana) is a native fruit from Central America and Mexico. This fruit still not known in Brazil, presents an orange-yellow pulp rich in carotenoids, which has attracted interest as a potential source of vitamin A. The purpose of this study was to determine the carotenoids content and pro-vitamin A values in the pulp of canistel, as well as the percentage of moisture and lipids in the pulp and seeds. Carotenoids were separated by open column chromatography. The content of total carotenoids was 226 ± 4 μg/g. Violaxantin and neoxantin were the predominant carotenoids with 196 ± 5 μg/g followed by zeta-carotene, beta-carotene 5,6-epoxide, beta-carotene and phytofluene. The seeds presented higher levels of total lipids with 4.6 ± 0.2 %, while pulp had 0.61 ± 0.03 % of total lipid. These results indicate that this fruit presented very high levels of total carotenoids when compared to other fruits regularly consumed, and may be considered as a good source of pro-vitamin A (59 ± 6 RAE/100g). However, the main carotenoids found in Canistel have no pro-vitamin A activity.
