Zusammenfassung:This study aimed to determine the effect of different storage temperatures on fruit quality of ambarella. The ambarella fruits were obtained from the Company CEAGESP-General Warehouses of Sao Paulo and transported in cool boxes to the laboratory, where they were selected for their appearance, maturity and lack of physical damage, then sanitized in 50 ppm chlorine-free solution and packaged in polystyrene trays wrapped with film of polyvinyl chloride (PVC). The experiment was a completely randomized design with three treatments (4, 8 and 25°C) and 5 times interval (0, 3, 6, 9 and 12 days after the experiment installation). In each survey, firmness, titratable acidity, soluble solids, ascorbic acid content and the skin color were evaluated, as well as the release of C[O.sub.2] by the fruit over time. It was observed that low temperatures prolong the shelf life of fruits and the storage temperature influences the characteristics, and the temperature of 8°C was the most suitable for the storage of ambarella fruits. Index terms: postharvest, tropical fruits, Spondias dulcis, Anacardiaceae. O presente trabalho teve como objetivo determinar o efeito de diferentes temperaturas de armazenamento na qualidade de frutos de caja-manga. Os frutos de caja-manga foram obtidos junto ao CEAGESP--Companhia de Entrepostos e Armazens Gerais de Sao Paulo, e transportados em caixas isotermicas para o Laboratorio onde foram selecionados quanto a aparencia, estadio de maturacao, ausencia de danos fisicos, depois sanitizados em solucao de 50 ppm de cloro livre e acondicionados em bandejas de poliestireno expandido, envolto por filme de policloreto de vinila (PVC). O delineamento experimental utilizado foi o inteiramente casualizado, com tres tratamentos (4°C, 8°C e 25°C) e 5 epocas de avaliacao (0; 3; 6; 9 e 12 dias apos a instalacao do experimento). Em cada coleta, foram avaliadas a firmeza, a acidez titulavel, os solidos soluveis, o teor de acido ascorbico, a cor da casca e, tambem, a liberacao de C[O.sub.2] pelos frutos ao longo do tempo. Foi observado que baixas temperaturas prolongam a vida util dos frutos e que a temperatura de armazenamento influencia nas caracteristicas avaliadas, sendo a temperatura de 8°C a mais adequada para o armazenamento dos frutos de caja-manga. Termos para indexacao: pos-colheita, frutos tropicais, Spondias dulcis, Anacardiaceae.
