above 500 °C. This can be attributed to endothermic dehydroxylation (or alternatively, dehydration) to produce disordered metakaolin (Al 2 Si 2 O 7 ). Dehydroxylation continued up to 900 °C [ 13 , 14 ]. This may be attributed to the gradual oxolation of

.54% (200–1000 °C). The TG curve of irinotecan/mSiO 2 had two mass losses: 14.57% (30–200 °C), 13.65% (200–1000 °C). It can be inferred that the mass losses at 30–200 °C was the vaporization and adsorbed water on the surface of the mSiO 2 and irinotecan

, the thermal stability of soy protein is low and it starts degrading above 170–180 °C [ 13 ]. Recently, structural transformations were induced in protein components under influence of gamma irradiation to increase the thermal stability [ 14
