근적외선분광광도법을 이용한 참기름중 이종식용유지 정량법에 관한연구 = Quantitative Analysis of Contents of Vegetable Oils in Sesame Oils by NIRS

다국어 초록 (Multilingual Abstract)

- The possibility of rapid non-destructive qualitative and quantitative analysis of vegetable oils such asperilla, corn, soybean and rapaseed oils in sesame oils was evaluated. A calibration equation calculated byMPLS(Modified Partial Least Squares) regression technique was developed and coefficients of determination forperilla oil, corn oil, soybean oil and rapaseed oil contents were 0.9992, 0.9694, 0.9795 and 0.9790 respectively.According to the data obtained from validation study, R2 of contents of perilla, corn, soybean, rapaseed oils were0.997, 0.848, 0.957 and 0.968, and SEP of content of them 0.747, 5.069, 3.063 and 3.000 by MPLS respectively. Theresults indicate that the NIRS procedure can potentially be used as a non-destructive analysis method for the rapid andsimple measurement of sesame oil mixed with other vegetable oils. the NIRS for perilla oil,corn oil, soybean oil and rapaseed oil were presumed as 2%, 15~20%, 15~20% and 10%, respectively.
