Nevertheless, it can be noticed that the mid point in the heat capacity jumps moves towards low temperatures as the moisture content increases, which is related to the well known plasticizing effect of water.
For tapioca starch films, Chang et al. (2000) found that the glass transition temperatures of cassava starch decreased from175 ◦C to 25◦C, as the moisture content increased from 6 to 26% (d.b.).
Perdomo et al. (2009) reported Tg values from 84 ◦C to 19◦C for amorphous CS with moisture contents of varying from 11 to 27% (d.b.), respectively.
