Composição de carotenoides em canistel (Pouteria campechiana (Kunth) Baehni)

Abstract

RESUMO -O canistel (Pouteria campechiana) é uma fruta nativa da América Central e México, ainda pouco conhecida no Brasil. Apresenta uma polpa amarelo-alaranjada, rica em carotenoides, que tem despertado interesse como potencial de vitamina A. O objetivo deste trabalho foi determinar o teor de carotenoides e o valor provitamina A na polpa de canistel, assim como os teores de umidade e lipídeos na polpa e na semente. Os carotenoides foram separados por cromatografia em coluna aberta. O conteúdo de carotenoides totais foi de 226 ± 4 μg/g. Violaxantina e neoxantina foram os carotenoides predominantes, somando 196 ± 5 μg/g, seguidos por zetacaroteno, betacaroteno 5,6-epóxido, betacaroteno e fitoflueno. A semente foi a parte do fruto que apresentou maior teor de lipídeos totais, com 4,6 ± 0,2 %, e a polpa, 0,61 ± 0,03 %. Os resultados indicam que o canistel apresenta teores de carotenoides totais muito elevados e pode ser considerado uma boa fonte de provitamina A (59 ± 6 RAE/100g), se comparado com outras frutas normalmente consumidas. No entanto, os principais carotenoides encontrados em sua polpa são destituídos de atividade provitamina A. Termos para Indexação: canistel, Pouteria campechiana, carotenoides, teor de lipídeos. CAROTENOIDS COMPOSITION OF CANISTEL (Pouteria campechiana (Kunth) Baehni)ABSTRACT -Canistel (Pouteria campechiana) is a native fruit from Central America and Mexico. This fruit still not known in Brazil, it 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.

Relevant physicochemical properties and metabolites with functional properties of two commercial varieties of PeruvianPouteria lucuma

“…The stage of maturity at the time of harvest and storage conditions can affect the moisture content of the fruit (Alia‐Tejacal et al, 2007; Fuentealba et al, 2016). In general, the moisture content of lucuma is lower than that of other Sapotaceae such as mamey (75%) and sapodilla (82%) (Moo‐Huchin et al, 2014), although a moisture value of 49.5% in canistel has been reported (Costa, Wondracek, et al, 2010). The total dietary fiber content was similar for both varieties (24.2%) and higher than that reported in sapote (17.2%–21.5%) (Mahattanatawee et al, 2006; Moo‐Huchin et al, 2014).…”

“…One of the most studied species of this family is P. sapota (mamey) which has been shown to be a source of many bioactive compounds such as polyphenols, carotenoids, and tocopherols (Ma, Yang, Basile, & Kennelly, 2004; Yahia, Gutiérrez‐Orozco, & Arvizu‐de Leon, 2011). Other Pouteria species such as P. campechiana (canistel) (Costa, Wondracek, Lopes, Vieira, & Ferreira, 2010), P. viridis (Ma et al, 2004), and P. macrophylla (da Silva, Gordon, Jungfer, Marx, & Main, 2012) have also been reported as rich sources of bioactive compounds.…”

“…Tengah dan Hindia Barat yang termasuk kedalam tanaman sawo-sawoan, sehingga sering disebut sawo Belanda (Costa et al, 2010). Buah Campolay dilaporkan sebagai bahan pangan yang kaya karotenoid dan berperan sebagai antioksidan maupun hepatoprotektif (Kubola et al, 2010;Aseervatham et al, 2013).…”

Optimization on process of ripe canistel (Pouteria campechiana) fruit flour based on several quality characteristics

“…Canistel fruit has an interesting yellow color that comes from carotenoid components. According to Lanerolle et al (2008) and Costa et al (2010), canistel fruit is an essential source of carotenoids in which the fruit has a total carotenoid content of 1.9-23.5 mg/g dry weight. In addition, Kong et al (2013) reported that the canistel fruit extract using 70% ethanol is a source of phenolic and flavonoid compounds.…”
