%X Thermal drying could lead to the deterioration of substance which affect its nutraceutical and chemical properties. Hence, thermal stability of substance is necessary in course of its drying to acertain the degree of temperature it will be subjected to. In this research, sclerotium of <i>Pleurotus tuberregium </i>is subjected to&nbsp;thermogravimetric analysis,&nbsp;differential thermal analysis and differential scanning calorimetry. Both thermogravimetric analysis&nbsp;and&nbsp;differential thermal analysis were conducted from ambient temperature to 1000<span style=\"white-space:normal;\"><span style=\"font-family:;\" \"=\"\"><span style=\"white-space:nowrap;\">กใ</span>C </span></span><span style=\"white-space:normal;\"><span style=\"font-family:;\" \"=\"\">at a rate of 20</span></span><span style=\"white-space:normal;\"><span style=\"font-family:;\" \"=\"\"><span style=\"white-space:nowrap;\">กใ</span>C/min constant heating rate, while differential scanning calorimetry was conducted from ambient temperature to 400<span style=\"white-space:nowrap;\">กใ</span>C&nbsp;at a rate of 10<span style=\"white-space:nowrap;\">กใ</span>C/min constant heating rate. Besides, the oxides contents of sclerotium of <i>Pleurotus tuberregium</i> were determined using x-ray fluorescence analysis and the mircostruture was determined with scanning electron microscopy. It was discovered that complete dehydration of the sample ended at about 110.38<span style=\"white-space:nowrap;\">กใ</span>C&nbsp;and oxidation reaction occurred between 233.42<span style=\"white-space:nowrap;\">กใ</span>C&nbsp;to 373.82<span style=\"white-space:nowrap;\">กใ</span>C&nbsp;with release of heat by the sample. Sclerotium of <i>Pleurotus tuber-regium</i> is thermal stable up to 233.42<span style=\"white-space:nowrap;\">กใ</span>C&nbsp;with decompostion of steroid which is its second major component at about 400<span style=\"white-space:nowrap;\">กใ</span>C&nbsp;to 480<span style=\"white-space:nowrap;\">กใ</span>C. The x-ray fluorescence analysis of sclerotium of <i>Pleurotus tuber-regium</i> revealed that Na<sub>2</sub>O, MgO, SiO<sub>2</sub>, Al<sub>2</sub>O<sub>3</sub>, and Fe<sub>2</sub>O<sub>3</sub> are the major compound and SEM analysis showed that&nbsp;it&nbsp;is a solid with amorphous structure having some fibrous skeleton. This study revealed&nbsp;that&nbsp;sclerotium of <i>Pleurotus tuberregium</i></span></span><span style=\"white-space:normal;\"><i><span style=\"font-family:;\" \"=\"\"> </span></i></span><span style=\"white-space:normal;\"><span style=\"font-family:;\" \"=\"\">could be dried to
