The possibility of rapid quantitative analysis of AV(Acid Value), Ⅳ(Iodine Value) and fatty acids in vegetable oils with NIRS(Near-infrared spectroscopy) was evaluated. A calibration equation calculated by MPLS regression technique was developed and correlation coefficient of determination for AV, Ⅳ, C16:0, C16:0, C16:1, C16:2, C16:6, and C20:0 content were 0.9727, 0.997, 0.9805, 0.942, 0.9987, 0.9994, 0.9966, and 0.975 respectively. According to the data obtained from validation study, R² of contents of perilla, corn, soybean, rapaseed oils were 0.897, 0.993, 0.935, 0.707, 0.994, 0.996, 0.984, 0.798, SEP of contents of 0.185, 1.367, 0.899, 0.640, 1.498, 1.360, 0.476, 0.076 by MPLS. The results indicate that the NIRS procedure can potentially be used as a non-destructive analysis method for the rapid and simple measurement of AV, Ⅳ and fatty acids in vegetable oils.
