The Skin Freckles is a papaya skin disorder that depreciates de fruit appearance and hampers its commercialization, although not lowering its nutritive value. Being the papaya a good source of ascorbic acid, beta-carotene and licopene this research aimed at determining L-ascorbic acid, P-carotene and licopene content in papaya fruits, from 'Formosa' and 'Solo' group varieties, with and without apparent physiological skin disease (skin freckles). Fruits were harvested in the Southeast Region of Brazil. L-ascorbic acid content was determined by titration technique. beta-carotene and licopene contents were determined by high performance liquid chromatography technique (HPLC). L-ascorbic acid content in papaya fruits ranged from (59.9 +/- 3.4) mg 100 g(-1) to (112.4 +/- 12.6) mg 100 g(-1) in fresh papaya Pulp. beta-carotene content ranged from (0.19 +/- 0.07) mg 100 g(-1) to (0.56 +/- 0.09) mg 100 g-1 and that of licopene ranged from (1.44 +/- 0.28) mg 100 g(-1) to (3.39 +/- 0.32) mg 100 g(-1) in fresh papaya pulp. L-ascorbic acid contents of papaya fruits with skin disease averaged 7.0 mg 100 g(-1) to 10.0 mg 100 g(-1) higher than those of papaya fruits without skin freckles (P < 0.05).
