Near infrared (NIR) diffuse reflectance spectroscopy is used for the measurement of size of sugar granules. Commercially available sugar samples were procured from the market and were ground using a home grinder to yield samples with varying particle size. The lot was subjected to differential sieving to create a set of hundred and ten samples. The mean particle size values of all the samples were determined using laser particle size analyzer and were used as reference values for calibration. NIR spectra of all the samples were recorded in diffuse reflectance mode. Partial least squares (PLS) chemometric method was applied for calibration. A separate set of twelve samples was created in a similar manner for prediction. Mean particle size values of all the samples in prediction set was also determined using laser technique and their near Infrared spectra were recorded. The mean particle size values of these samples were predicted using the derived calibration curve and were compared with laser reference values. A good correlation was obtained between NIR predicted values and laser reference values. The present work demonstrates that the near infrared diffuse reflectance spectroscopic technique can be successfully applied for determination of particle size of sugar.
