Sugarcane Analysis Using Near Infrared Spectroscopy
ABSTRACT NEAR Infrared (NIR) reflectance (R) spectroscopy was used to determine the pol (dextro-rotary substances), fiber, sugar and moisture contents of shredded sugarcane samples. The analysis of the NIR data was based on the second derivative of the log (1/R) values. A set of four wavelengths was then selected and calibration correlations were determined for these wavelengths for each constituent. A standard analysis was also performed for comparison with the NIR results. There was no significant difference between the pol, fiber, sugar, and moisture values using the standard press method and the NIR method developed in this study (p>0.01). Correlations between the two methods were also determined and the values were 0.957, 0.834, 0.956, and 0.957 for pol, fiber, sugar, and moisture, respectively.
