Experimental Researches on Near-Infrared Reflectance Spectroscopy to Analysis of Protein Content in Wheat and Soybean

Near-Infrared Reflectance (NIR) spectroscopic analysis is a new technique. This paper describes the principles of NIR spectroscopy and the technique of NIR spectroscopic analysis, discusses some major variables affecting NIR spectroscopic analysis, and first applies the finite-difference trans form that simulates deri-vatives to measurement of protein content in wheat and soybean using the Infra Alyzer 450 with 19 fixed filters. The experime-ntal results are satisfactory.
