The Experimental data of Differential Scanning Calorimetry (DSC) under non-isothermal conditions of Xanthan gum biopolymer at different heating rates (2 ≤ β ≤ 10) are reported and discussed. From the heating rate dependencies of the glass transition temperature (Tg),the activation energy for glass transition (Eg) is determined by utilizing well known methods, Piloyan and Coats & Redfern. The methods of Piloyan and Coats & Redfern utilizes only one DSC curve at an arbitrary heating rate and these are compared with the multiple heating rate methods like, Kissinger and Ozawa.
