Investigation on Nutritional Values of Three Different Ananas comosus (L.) Merr. Species Planted in Vietnam

Abstract

This study aimed to evaluate the nutritional values, phytochemicals, antioxidant activity, and anti-nutritional factors of three different pineapple cultivars (Cayenne, Queen, and MD2) cultivated in various provinces of Vietnam. The pineapple samples were collected from many farms ranging from the Central to the South of Vietnam. The analyses were performed as per standard test methods (the European standard and Association of Official Agricultural Chemists - AOAC methods). In general, there were no significant differences in energy-yielding nutrients (carbohydrates, fats, and protein). However, significant differences were observed in vitamin and mineral content. The MD2 cultivar had a high level of vitamin B5 and a low concentration of calcium, whereas both Cayenne and Queen were rich in vitamin C and chlorine. All three studied pineapple varieties exhibited moderate levels of phenolics and flavonoids, low concentrations of bromelain, and weak antioxidants. All three pineapple species studied contained low concentrations of oxalates and a void of tannins. These findings scientifically contribute valuable information to the food database system and can be considered in diet planning.
