Variable temperature Fourier transform infrared (FTIR) spectroscopy was used to study the transition between the micellar and the coagel phases, and between the cubic and the coagel phases, for the hexadecyltrimethylammonium sulfate (CTAS)/water system. The phase transition takes place at 15°C for t
## Abstract When purified potato starch granules are heated in the presence of limited amounts of water (less than 1.5 H~2~O: starch, w/w), two endothermic transitions are observed by differential scanning calorimetry. The lower temperature endotherm is always observed at a fixed temperature, 66°C;
