The aim of the present study was to investigate the differences between affordably priced vegetable oils (soybean, corn, rice bran, grape seed, and sunflower oils) and relatively expensive vegetable oils (sesame, perilla and flaxseed oils), based on their major (e.g., fatty acids) and minor components (e.g., phytosterols, sesamin, and -tocopherol) analyzed by gas chromatography-flame ionization detector. The relatively expensive edible oils exhibited lower levels of palmitic acid. Flaxseed and perilla oils exhibited linolenic acid content of more than 50 % and they contained significantly higher -sitosterol content than that in other oils. The relative ratio of campesterol/ -sitosterol could be helpful for differentiating them from other vegetable oils. Sesame oil only contained a unique compound called sesamin. The relatively expensive oils possessed higher -tocopherol content, compared with other vegetable oils including ricebran, grapeseed, and sunflower oils. Therefore fatty acid, phytosterol, sesamin, and -tocopherol analyses could be used as important indicators for discriminating the relatively expensive edible oils from the other oils.

법과학 분야는 사회정의 구현에 있어 크나큰 가치가 있음에도 불구하고 우리나라에서는 이 분야에 대한 인식이 미흡하여 선진 외국에 비해 침체되어 있는 실정이다. 이에 우리나라에서도 법과학 분야와 관련 있는 학계, 연구기관, 수사기관 등 유관 단체들로 구성된 한국 법과학회를 창립하여 이 분야를 활성화 시켜 과학수사를 한층 더 발전시키기 위함을 목적으로 한다.
