Estudo do valor nutricional e capacidade antioxidante dos frutos Mangaba (Hancornia Speciosa Gomes) e Noni (Morinda Citrifolia Linn) oriundos do Estado do Pará

Abstract

In the search for the identification of new natural sources with antioxidant capacity in the state of Pará, this work aimed to carry out the physicochemical characterization and evaluate the antioxidant activity and phenolic compounds in the pulp of noni and mangaba fruits. In the pulp of noni and mangaba, the proximate composition (moisture, ash, proteins, carbohydrates, lipids and fibers) was determined. Noni and mangaba pulps presented low calories 27.83 and 68 kcal/100g respectively. The antioxidant capacity was determined by the ABTS method. In the noni pulp, the antioxidant capacity was determined in the aqueous extract and in the MeOH extract (50%)/acetone (70%), the aqueous extract showing the highest antioxidant capacity (14.5 µM trolox/g), in the mangaba pulp the antioxidant capacity showed 8 µM of tro-lox/g). Noni and mangaba pulps showed high levels of vitamin C, 170.66 and 144 mg/100g, respectively. The phenolic compounds of noni and mangaba were 129.66 and 115 EAG mg/100g respectively. This research provided a better understanding of the chemical composition and functional properties of Noni and Mangaba fruit pulps produced in the state of Pará.
