초록
영지, 참깨, 칡과 같은 특용작물의 수입산 또는 국내산인지의 여부를 확인하기 위하여 전자코를 사용하였다. 특용작물이 배출하는 가스성분을 아무런 전처리 과정 없이 12개의 conducting polymer sensor로 감지하고 여기서 얻어진 자료를 판별분석을 통하여 특용작물의 원산지가 수입산 또는 국내산인지를 판별할 수 있었다. 원산지를 모르는 시료(영지, 참깨)를 분석한 결과 이들 농산물이 수입산인지 국내산인지를 뚜렷하게 구별할 수 있었다.
The discrimination of the agricultural origin, especially locally produced or imported from the products such as Ganoderma lucidum, sesame and arrowroot were investigated by using the electronic nose. Volatile components from these products were discriminated by twelve of conducting polymer sensors without any pretreatment. Pattern recognition was carried out. Multiple discriminant analysis showed the difference between imported agricultural product and locally produced ones such as Ganoderma lucidum, sesame and arrowroot. Unknown habitat of sesame and arrowroot could be identified by multiple discriminant analysis whether the imported or the locally produced one.
