Mango slices of Tommy Atkins, Haden and Keitt varieties were dehydrated at different levels of water loss, frozen at increasing freezing rates. They showed different behaviour. The Keitt variety showed greater sensibility to the pre-drying treatment and presented higher decrease on dripping loss. This effect, however, was sensible only when dehydration values were lower than 20% in weight loss. The reduction of the amount of ice formed during freezing process was quantified.
