Determination of the Effect of Moisture on Gliadin Glass Transition Using Mechanical Spectrometry and Differential Scanning Calorimetry

Abstract

Abstract Gliadin showed a glass to rubber transition typical of an amorphous polymer. Mechanical spectrometry and differential scanning calorimetry were used to determine the glass transition temperature ( T g ) in the moisture range of 6.2–27.2% (wet basis, wb) and bone dry to 16.6% (wb), respectively. The T g obtained with both of these techniques could be superimposed. The T g could be successfully predicted using the Gordon‐Taylor equation.
