Excellent near-infrared spectroscopy of edible oil quality and model sharing among different instruments can improve the utilization of the model and meet the development needs of the edible oil industry.Aiming at the problem of model transfer on the two indexes of edible oleic acid value and peroxide value,this paper mainly adopts the slop/intercept correction algorithm,combined with the partial least squares correction model on the main instrument,and studies the calibration transfer from the near-infrared spectroscopy model of edible oleic acid value and peroxide value.The results show that the slop/intercept correction algorithm has better linearity and effect between the VERTEX 70 and Antaris Ⅱ (fiber optic probe components)for the same optical fiber probe scanning.The root mean square error of prediction of the acid value and peroxide value decreased from 54.675 6 and 1 912.219 4,respectively,to 0.441 9 and 6.752.The slop/intercept algorithm has better effect on the same principle of instrumental oleic acid value and peroxide value,and the correction effect of edible oleic acid value is better than that of peroxide value correction effect.The results of this study are of great significance to the extensive application of the rapid analysis model of edible oil quality.
