This study was carried out to find optimum roasting condition of sesame seeds for making seed season and oil treated with different temperatures and time intervals. Sesame seeds with 17~18% of moisture content were treated under fixed and changed roasting temperature conditions. The fixed temperatures are ranged from 160 to 240℃ with 20℃ intervals. The changed temperatures were treated at low(160 and 180℃) and medium(200 and 220℃) for 10 minutes, and at high(220 and 240℃) for 3 minutes. Meanwhile, roasting times were 20-30 minutes longer under low temperature condition and 3-5 minutes shorter under high temperature condition. The optimum roasting temperature and time were determined as 220℃ and 3 minutes for producing seed season, and as 220℃ and 5 minutes for sesame oil, respectively, in roasting with small quantity of sesame seeds. On the other hand, in the large scale roasting condition, those showed 240℃ and 15 minutes in for producing seed season, and 280℃ and 10 minutes and 260℃ and 15 minute for producing seed season in white-colored sesame variety and black-colored sesame variety, respectively.
