Levels of ß-carotene, ascorbic acid, and total phenols in the pulp of five commercial varieties of mango (Mangifera indica L.)

John A. Manthey, Penelope Perkins-Veazie

Abstract


Five varieties of mangoes from four countries were evaluated with multiple harvests over a year to compare the ß-carotene, total phenol, and ascorbic acid levels of the fruit pulp. Only soft fruit (0.5 to 1 N compression) with a minimum of 10% soluble solids were used for these measurements to minimize ripeness variability. Ascorbic acid ranged from 11 to 134 mg·100 g–1 pulp puree, and ß-carotene varied from 5 to 30 mg·kg–1 among the five varieties. Total phenolic content ranged from 19.5 to 166.7 mg gallic acid equivalents (GAE)/100 g puree. The varieties ‘Tommy Atkins’, ‘Kent’, ‘Keitt’, and ‘Haden’ had similar total phenolic contents, averaging 31.2 ± 7.8 mg GAE per 100 g puree, whereas ‘Ataulfo’ contained substantially higher values. Country of origin and harvest dates had only minor influences on these parameters.
