evaluate the impact of unfreezable water on the staling of bread loaves, bread crust samples were analysed after 7 days of storage(Table 3). According to the obtained thermograms, a significant phase transition at 30.9 to 31.9 C was observed which can be attributed to the glass transition of the crust systems. Moreover,two endothermic peaks, first at 48.4e51.1 C and second at 154e 161 C were also detected and attributed to starch retrogradation and the formation lipideamylose complexes (Czuchajowska &Pomeranz, 1989).
