| Summary: | Abstract: The commercial classification of fruits organizes commercialization and promotes compliance. The aim was to propose classes for umbu fruits based on fresh mass. A total of 4,140 fruits from four harvests of the BRS-68 umbu cultivar (EPAMIG-C01) with average mass of 87.64 g ± 13.99 were used, individually weighed on analytical precision scale, and, the mean and standard deviation of 3,717 fruits within the mean confidence interval were considered for class stratification. Five size classes were determined, medium (= 50 and < 65 g), large (= 65 and < 75 g), giant (= 75 and < 100 g), extra (= 100 and < 110 g) and premium (= 110 g), however, three classes are recommended, large (= 50 and < 75 g), giant (= 75 and < 100 g) and premium (= 100 g), due to their easy adoption and use.
