Description
In this work, we use Differential scanning calorimetry (DSC) to detect the de-
naturation of pea protein isolate (PPI) with different relative humidity (20% RH
and 80 %RH) in different equilibrium time ( 4 months and 7 days ). Using this
approach, we obtained the temperatures of PPI denaturation and decomposition,
and also concluded that time has an important effect on the redistribution of water.
We also use DSC and Thermogravimetric analysis ( TGA ) to measure pea protein
samples treated by four ways ( heating, adding dithiothreitol(DTT) solution ). We
conclude that samples used four ways to treat are not stable and they will go back
to stable state. In addition, our samples are crystalline and amorphous except old
pea protein that is amorphous.
