The composition of Blighia sapida fruits is reported to differ based on its origin, variety, and preservation technique. In this study, the effect of drying method on the composition as well as the antioxidant activity of oven-dried and sun-dried B. sapida aril flour and oil were examined using standard procedures. Sun-dried B. sapida aril flour had significantly higher protein and fat content compared to the oven-dried flour. In addition, sun-dried B. sapida aril flour contained a more diverse phytochemical profile compared to the oven-dried flour. However, oven-dried B. sapida aril oil (ODAO) showed a higher percentage of unsaturated fatty acids compared to oil from the sun-dried B. sapida flour (SDAO). On the other hand, SDAO showed significantly higher DPPH scavenging and nitric oxide inhibitory activities compared to ODAO. Based on these findings, sun-drying is recommended for both nutritional purposes and other health-promoting usage such as antioxidant, over oven-drying.
Résumé
La composition des fruits de Blighia sapida diffère selon leur origine, leur variété et leur technique de conservation. Dans cette étude, l’effet de la méthode de séchage sur la composition ainsi que l’activité antioxydante de la farine et de l’huile de B. sapida aril séchées au four et au soleil sont examinés selon des procédures standard. La farine de B. sapida aril séchée au soleil avait une teneur en protéines et en graisses nettement plus élevée que la farine séchée au four. Toutefois, la farine de B. sapida aril séchée au four présente un profil phytochimique plus diversifié que celle séchée au soleil. L’huile de B. sapida aril séchée au four (ODAO) présentait un pourcentage plus élevé d’acides gras insaturés que celle séchée au soleil (SDAO). En outre, l’ODAO a montré des activités de piégeage du DPPH et d’inhibition de l’oxyde nitrique significativement plus élevées que la SDAO. Sur la base de ces résultats, le séchage au soleil pourrait être plus adapté à des fins nutritionnelles, alors que pour d’autres usages favorables à la santé, tels que les antioxydants, le séchage au four semblerait plus approprié.
