A comparison between the proposed method and methods of other reports was made to evaluate the proposed method. Among the reports in which NIRS was used to determine AV of edible oil, Rao’s method was built for one type of oil (peanut oil) with a R2 of 0.9379 and a RMSE of 0.5771 for the prediction set ( Rao et al., 2009). Pereira’s method was built for four types of oils (corn, soya, canola and sunflower oil) with a R2 of 0.9400 for the calibration set ( Pereira et al., 2008), and El-Abassy’s method was for one type of oil (olive oil) with a R2 of 0.9631 for the calibration set ( El-Abassy et al., 2009). In contrast, our proposed method was used for six kinds of oils with better performances, based on the use of the UV–Vis spectrophotometer quite cheaper than NIR spectroscope. Therefore the practicability and advantages of this proposed method was conspicuous.
