The cold pressed sesame-oil process is able to preserve all the valuable vitamins and nutrients available in sesame seeds. Several studies have been carried out with a screw press under-20-MPa of pressure and its effects on oil extraction have been researched. The aim of this research was to investigate the effects of the various pressures (ranging from 20-60 MPa) and temperatures (ranging from 40-60oC) on sesame oil yield recovery by using this mechanical pressing process. The pressing time was set at 10 minutes for all experimental conditions. It was found that the highest value of oil yield recovery was at the 60 MPa and 40oC. When the multiple regression analysis was carried out, the results showed that the pressure, temperature and interaction between these two factors had significant effects on sesame oil recovery yield.
