In this way, the aim of this study was to evaluate the acceptance of ‘Navelina’ [Citrus sinensis (L.) Osb.] navel oranges by consumers and the purchase intent, through sensory evaluation. To perform the harvest, the fruits were first analyzed in relation to the physical-chemical characteristics. Then, 131 untrained panelists representing the consumers were asked to evaluate samples of ‘Navelina’ through the acceptance test performed in individual booths with white light, according to the fruit attributes: appearance, firmness, aroma and taste.
