Abstract This paper studied the influence of using pre-procession such as smooth, 1st derivative and baseline correction on the analyｓis of near-infrared spectrum. Comparing the analysis results by the pre-procession methods, and using PLS arithmetic, the best pre-procession was determined. In smooth pre-procession method, the best smooth points were proposed for regression using PLS. The analysis result is satisfactory.
