Determination of total reducing sugars in potato samples using near-infrared spectroscopy Academic Article uri icon


  • Near-infrared (NIR) transmittance spectroscopy was used to predict the total reducing sugar content of sliced potato samples. Partial least squares statistical analysis tools were used in the development of the prediction models. The best results were obtained for samples of one potato type. This preliminary study showed that NIR spectroscopy is accurate enough to be used to determine total reducing sugars in potatoes but that separate prediction models will be needed for each potato type. The advantage of the NIR procedure is that it is a non-destructive and fast method for measuring the required compounds. The potential application of this method is the on-line measurement of total reducing sugars for correct product handling and processing.
