The SMRI-NIRS technology: development, validation and benefit* [Full subscriber]

Abstract         The Sugar Milling Research Institute NPC (SMRI) has developed a simple to use near-infrared spectroscopy (NIRS) transmission-based analysis method as an alternative to conventional methods for analysis of sugarcane factory stream samples.  The technology provides rapid, simultaneous analysis of brix, pol, sucrose, glucose, fructose, conductivity ash, colour and pH for all streams and additionally, dry solids for final molasses and eliminates the need for sample clarification chemicals.  The analyte prediction equations were developed using conventional results of samples from 14 South African factories, analysed at SMRI using SANAS/ISO17025 accredited test methods, and NIRS scans of the same samples using…
