This study aimed to establish the binomials temperature vs. time, which can cause chilling injury in mangoes 'Palmer'. Semi-ripe fruits were harvested and carefully transported to the laboratory where they were selected, standardized according to the color, size and absence of injuries and treated with fungicide before being stored at 2 ºC, 5 ºC and 12 ºC up to 28 days. The fruits were evaluated weekly for the occurrence of decay, chilling injury, respiratory activity, peel and pulp color, fresh weight mass, firmness, soluble solids (SS) and titratable acidity (TA) and ratio. The results showed that the symptoms of chilling injuries were exteriorized after 7 days of refrigerated storage at 2 ºC or 5 ºC, and the fruits did not differ in the severity of the damage. The presence of damage did not prevent the development of the characteristic pulp color, although it has led to the darkening of the skin and has affected the normal ripening of fruits. Fruit stored at 12 ºC showed no signs of cold damage, and no impairment to their normal metabolic processes.
