Near infrared (NIR) analysis has been finding widespread application in beet sugar manufacture, in sugarcane breeding programs, and in analysis of sugar products in Europe, the USA and Australia. Experience with the use of a scanning NIR spectrophotometer in a sugarcane factory laboratory is reported. Previous work has described use of filter instruments; these scanning instruments offers wavelength selectivity, wavelength combinations and accuracy far greater than those previously available. Juice samples (grower samples) were analyzed at different periods during the crop, and in different geographical locations. Results from this very rapid analysis compared favorably with the factory's pol, Brix and purity analysis. Analysis of bagasse for moisture and sugar is also reported. Applications to analysis of raw sugars for pol, sucrose, invert, ash, color, dextran and starch are also presented and discussed.
