Abstract : The effect of the osmotic dehydration in sucrose solution (44% w/w) for 80 minutes on the total carotenoids content of dried 'Tommy Atkins' mango was investigated. The osmotic process was carried out in an incubator at 34°C and agitation of 100 rpm. Drying tests were conducted in vertical tray dryer at two different temperatures (60 and 70°C) and air velocity of 3.0 m/s, until the sample final moisture reached 25% (wet basis). The osmotic dehydration could be considered to be an efficient method, as the pretreated dried samples had lower carotenoids losses, an important quality attribute of the mango.
