FISIOLOGIA, QUALIDADE E POTENCIAL DE FRUTOS DE DIFERENTES ACESSOS DE MANGABEIRA (Hancornia speciosa)

Abstract

The mangabeira is a native fruit tree found on the coast of the Northeast of Brazil, in areas of coastal trays. These trees show white flowers, reddish - yellow fruit with fleshy orange pulp and of unique flavor, being widely appreciated and consumed in the producing regions, presenting. potential for fresh consumption and for agro-industry, in the form of several products. However, for the mangaba to have greater visibility in the markets, more studies of the physiology, quality and functional potential to ensure its insertion in the market are necessary. Thus, the objective of this work is to evaluate the physiology, quality, bioactive compounds and antioxidant activity of mangrove fruits from the germplasm bank at the EMEPA - João Pessoa / PB station. Mangabas were harvested at the mature green stage and transported to the Laboratory of Biology and Postharvest Technology (CCA / UFPB). The evaluations were: fresh mass, pulp yield, length, diameter, firmness, skin color (L, a *, b *), CO2 production, soluble solids, titratable acidity, SS / AT ratio and pH. The levels of bioactive compounds (ascorbic acid, yellow flavonoids, anthocyanins, total extracts polyphenols (PET), antioxidant activity and peroxidase) and peroxidase activity (POD) were also measured. The fruits of the accessions did not differ in the pH, titratable acidity, total extractable polyphenols for skin and pulp, the yellow flavonoid content in the pulp, as well as the antioxidant activity in the skin and enzymatic activity in the pulp and skin. Fruits of PG 3 access were characterized by the higher fresh mass, yield, length, SS, totsl anthocyanins content, yellow flavonoids (skin), PET (skin and pulp), antioxidant activity (skin and pulp) and lower POD activity for fresh consumption or for industry.
