Abstract : Five composite samples were analysed for each of 5 cultivars. Although slight qualitative variations were detected, the major difference between the cultivars was in the quantitative composition. ?-Carotene was consistently the principal carotenoid, accounting for 48-84% of the total, while the epoxycarotenoids violaxanthin, luteoxanthin and mutatoxanthin together made up 13-49%. Other carotenoids detected were ?-carotene, mutatochrome, ?-cryptoxanthin and auroxanthin. Cv. Extreme had the highest ?-carotene and total carotenoid contents (2545 and 3045 ?g/100 g, respectively) and Haden had the lowest contents (661 and 1387 ?g/100 g, respectively). The vitamin A values followed the ?-carotene trend, the mean ranging from 115.3 to 430.5 RE/100 g, with cv. Extreme presenting the highest and Haden the lowest values. The pH of the fruits ranged from 3.9 to 4.2 and °Brix from 14.5 to 24.5.
