The present invention relates to a method for preparing sesame oil, and more specifically, to a method for preparing high-purity sesame oil wherein roasted sesame seeds are provided with steam and an oil is extracted therefrom, and the extracted oil is then filtered twice, and foreign residues are completely removed by means of a third filtration, thereby producing a high-purity sesame oil having a clean taste and a clear golden color. The method for preparing sesame oil comprises: a roasting step in which cleanly washed sesame seeds are dried, and roasted in a roaster for 7-10 minutes at a temperature of 150-170°C a steaming step in which the roasted sesame seeds are steamed in a steam tank for 4-6 minutes at a temperature of 70-90°C an oil-pressing step in which the roasted and steamed sesame seeds are pressed to produce a sesame oil a first filtration step in which the sesame oil is passed through a filter to remove particles equal to or greater than 0.5 &mu a second filtration step in which the filtered sesame oil from the first filtration step is passed through a filter to remove particles equal to or greater than 0.2 &mu a third filtration step in which the filtered sesame oil from the second filtration step is passed through a filter charged with diatomaceous earth to remove impurities through adhesion and a packaging step in which the filtered sesame oil from the third filtration step is injected in a container and packaged therein.COPYRIGHT KIPO 2016본 발명은 참기름의 제조방법에 관한 것으로서, 더욱 상세하게는 볶은 참깨에 증기(蒸氣)를 부여하고 착유(窄油)한 기름을 1,2차 여과한 후 규조토 광물 필터층을 거치는 3차 여과에 의하여 불순물이 완벽하게 제거되어 맛이 깨끗하면서도 맑은 황금빛을 띠는 고 순도의 참기름 제조방법에 관한 것이다.전술한 본 발명의 특징은, 깨끗하게 세척된 참깨를 건조하여 로스터(roster)에 넣고, 150∼170℃의 온도로 7∼10분간 볶아주는 로스팅(roasting)단계 볶아진 참깨를 스팀탱크에 투입하고 70∼90℃의 증기를 부여하여 4∼6분간 쪄내는 증자(蒸煮)단계 볶아지고 수분이 부여된 참깨를 압착하여 기름을 짜내는 착유(搾油)단계 짜낸 참기름을 여과기를 통과시켜 0.5μ이상의 입자를 걸러내는 1차 여과단계 1차 걸러진 참기름을 여과기를 통과시켜 0.2μ이상의 입자를 걸러내는 2차 여과단계 2차 걸러진 참기름을 규조토(硅藻土) 알갱이들이 충전된 여과기를 통과시켜 불순물을 흡착하여 제거하는 3차 여과단계 및
