Samples of bread crust (2 h and 7 d after baking) and adjacent to crust bread crumb (2 h after baking) were pressed, weighed in a hermetically sealed aluminium pan and analysed using a Perkin-Elmer DSC. Calibration of the DSC was achieved using pure indium. Samples were rapidly cooled (10 C/min) from 25 to 80 C,held isothermally for 2 min and heated from 80 to 180 C at the rate of 5 C/min.
