This work evaluated the effects of two drying temperatures (40 and 60 degreesC) on some physical and chemical properties of chestnuts, both dried and after their rehydration using steam at 100 degreesC. The morphological characteristics of fresh starch granules were characterized by a round or oval shape, with diameter length ranging from 3.0. to 15.0 mum. After drying and rehydration, the granules appeared more shapeless and the surfaces were quite rough. The changes also caused more of the open pore volume fraction in samples dried at 60 degreesC, than in those dried at 40 degreesC and, much more, than the fresh samples. Also, calorimetric behaviour, starch and simple sugar changes after chestnut drying and rehydration, were studied. (C) 2004 Elsevier Ltd. All rights reserved.
