**6.8 Differential scanning calorimetry**

In DSC testing is the thermal analysis technique in which the heat flow in or out of the sample for testing is determined as the function of temperature. Here the biopolymer sample was taken and exposed to a controlled temperature program. The glass transition temperature was determined. The heat flow range was 50–300°C. The DSC thermogram was recorded, interpreted, and reported [4, 62].
