참기름의 이종기름 함유 유무를 판단하기 위한 기초자료를 얻고자 국내산 참기름의 옥배유를 혼합한 시료와 중국산 참기름에 대하여 지방산, sesamolin 및 sesamin 함량, AOM에 의한 유도기간을 각각 조사했다. 국내산 참기름에 옥배유를 혼합할 경우, stearic acid는 옥배유를 20% 이상 혼입한 참기름에서 국내산 참기름과 뚜렷한 차이를 나타내었다. 그리고 Oleic acid와 linoleic acid에서는 10%의 혼합시에도 미약하나마 함량의 차이를 보였다. 참기름에 옥배유를 혼합하 fruddn stearic/linoleic 비율은 옥배유의 혼입된 함량과 비례하였다. 국내산 참기름에 이종기름으로 drhqodb를 30% 혼합시에는 sesamolin이 18.3%, sesamin이 21.0% 감소하였다. AOM에 의한 유도 기간은 중국산, 백배유 20% sesamolin과 sesamin의 함량 및 AOM에 의한 유도기간 측정 등이 적용하리라 생각된다.
Korean sesame oil mixed with corn oil and Chinese sesame oil were subjected to instrumental determination for fatty acid composition, sesaminol and sesamin contents, and induction period by AOM test to obtain basic data for ascertaining the truth of pure sesame oil, respectively. In sesame oil mixed with corn oil, stearic acid content of sesame oil containing above 20% corn oil was remarkably discriminated from that of pure sesame oil. Oleic and linoleic acid contents of sesame oil with 10% corn oil were significantly differnt from that of pure sesame oil. Stearic/linoleic acid ratio of sesame oil mixed with corn oil dcreased in proportion to corn oil content in sesame oil. Sesamolin and sesamin contents of sesame oil containing 30% corn oil were lower 18.3% and 21.0% than those of pure sesame oil, respectively. Induction periods of sesame oil by AOM were 8.14~9.24 hrs in Chinese sesame oil and sesame oils inculding 20% and 40% corn oils, but around 16hrs in Korean pure sesame oil. Based on the above results, it is considered that the comparisons of fatty acids, sesaminol and sesamin contents, and induction period by AOM test might be one of the potential criteria in discriminating between pure sesame oil and sesame oil mixed with corn oil.
