Abstract

The international market for sesame lately begun considered by many countries including Indonesia. Export prospects depend on the quality sesame, this proved that the demands of importing countries should sesame oil yield of more than 30% and low levels of pesticide residues. Sesame seed oil recovery rate in Indonesia amounted to 20-25% .Though containing sesame oil. The process of extracting the oil is through mechanical extraction is pressed. How this is done to separate the oil from the high oil content material up to 30-70% by using a tool called compression machine. The method used was a completely randomized design with two factors, one factor which heating method (oven, steamed, and roasted) with a temperature of 85oC control and factor II was prolonged heating (5,10, 15 and 20 minutes) with three replicates. Sesame seeds are heated then extracted. Used pressure of 350 kN. These experiments provided information maximum yield, moisture content, color, pulp, mass balance and color. The results showed that the best research contained in the roasting for 20 minutes with the result 34.12% yield, water content 13.17%, water content after heating 6.97% and amounted to 56.96% pulp. As for the best color that was bright yellow in the roasted for 20 minutes.
