Alterações Nos Níveis De Antioxidantes Em Polpa De Manga

Abstract: De acordo com o padrão respiratório, a manga é uma fruta climatérica e, por isso, amadurece e se deteriora rapidamente mesmo em ambiente refrigerado. Este trabalho teve como objetivo avaliar o método mais eficaz de congelamento e armazenamento para polpa de manga ‘Palmer’. Os métodos de congelamentoe armazenamento testados foram: freezer a -20±2°C (F), congelamento em nitrogênio líquido e armazenamento em freezer -20±2°C (CNF), ultra freezer a -80±2°C (UF) e com congelamento em nitrogênio líquido e armazenamen… Show more

“…The ketone extract was filtered through filter paper (8 μm), and the volume was completed to 25 mL in a tube (Silva et al 2014). The absorbance was determined at 470, 646.8 and 663.2 nm, and carotenoid levels were determined according to the Lichtenthaler equations (1987).…”

“…These values were converted to color angle, λ° = tan −1 b/a, which indicates the hue angle of the sample (0° or 360° = red, 90° = yellow, 180° = green, and 270° = blue) (Silva et al 2014). To determine the coloring of the rind, two readings were taken on opposite sides of each fruit.…”
