Abstract

Pineapple industry is one of the important agricultural sectors in Malaysia with 76 cultivars planted throughout the country. This study aims to generate useful nutritional information as well as evaluating antioxidant properties of different pineapple commercial cultivars in Malaysia. The bioactive compound content and antioxidant capacity of 'Josapine', 'Morris' and 'Sarawak' pineapple (Ananas comosus) were studied. The pineapple varieties were collected at commercial maturity stage (20-40% yellowish of fruit peel) and the edible portion of the fruit was used as sample for evaluation. The bioactive compound of the fruit extracts were evaluated by total phenolic and tannin content assay while the antioxidant capacity was determined by ferric reducing antioxidant power (FRAP). From the results obtained, total phenolic and tannin content was highest for 'Josapine' followed by 'Morris' and 'Sarawak'. With respect to FRAP, 'Josapine' showed highest reducing capacity, followed by 'Morris' and then 'Sarawak' having the least value. The bioactive compounds content are positively correlated with the antioxidant capacities of the pineapple extracts. This result indicates that the total phenolics and tannin content present in the pineapples may contribute to the antioxidant capacity of the pineapples.
