Abstract : The aim of this work was to evaluate the quality and postharvest life 'Tommy Atkins' mango subjected to mechanical injury and storage under ambient conditions. Adopted the approach entirely at random in time subdivided parcels scheme, considering the mechanical injuries plots, subplots, and periods of storage (0, 3, 6, 7, 8 and 9 days), with four replicates and two fruits per experimental unit. The mechanical injuries (T) were induced in the laboratory considering the following criteria: T1, witness, fruit without injury; T2, fruits with impacts, two impacts per fruit; T3, fruit subject to cuts, two cuts for fruit; T4, fruits submitted to the abrasion, 10 cm2 area. The characteristics evaluated were: loss of fresh mass, soluble solids (SS), pH, titratable acidity (TA), SS/AT, colour of flesh and external appearance. The abrasion injuries caused greater loss of fresh mass at the end of the store. The fruits that have suffered cutting and abrasion, showed the lowest values of titratable acidity, and reduction of 0,60% to 0,30% citric acid of the beginning to the end of the store. As to the external appearance, the mangoes maintained satisfactory quality for marketing up to seven days of storage in ambient conditions, regardless of the occurrence of mechanical injuries.
