| Abstract This study aimed to evaluate the behavior of the bioactive compounds and the antioxidant activity of raw mangaba fruit (Hancornia speciosa Gomes), in addition to the influence of preservation methods (freezing, lyophilization, and foam layer drying) on these biocompounds. Samples were evaluated for ascorbic acid, phenolic compound, and carotenoid content and total antioxidant activity by the DPPH, ABTS, and FRAP methods. The analyses were performed in triplicate for each sample and the results were expressed as the mean ± standard deviation. A significant correlation was observed between the content of total phenolic compounds and the total antioxidant activity, as determined by the FRAP method, which showed that the content of ascorbic acid... |

| Abstract: The objective of this work was to evaluate the physicochemical attributes and vitamin C contents of fruits of five Brazilian genotypes of feijoa (Acca sellowiana), at harvest and after cold storage. The Alcântara, Mattos, Helena, and Nonante cultivars, as well as accession 2316, were studied. The assessed attributes were: fresh mass loss, titratable acidity, soluble solids contents, soluble solids contents/titratable acidity ratio, pH, skin and flesh color, texture, and vitamin C contents (skin and flesh). After storage, there were reductions of 2.9% in soluble solids contents, of 32.2% in titratable acidity, and of approximately 85% in texture attributes, besides increases of 36.3% in the soluble solids contents/titratable acidity ratio and of... |
