Evaluation of emerging technologies: Importance of correct analytical procedures

Development of new technologies often requires revisiting analytical method s used routinely for monitoring factory performance. For example, introduct ion of membrane filtration or chromatography in both the beet or cane sugar industries will affect the quality of processed juices and syrups, Convent ional analytical methods work well For comparison of the results for establ ished technologies. The methods specific to a certain component of a soluti on are less affected by technology change. However. the bulk methods, such as refractometry, polarimetry. spectroscopy, etc., reflect the cumulative c ontribution of various components. Therefore, for example, the same purity or color of a solution may result in different processing characteristics o f juice or syrup and different quality of the final product. Examples are d iscussed showing the differences in analysis of color, lime salts content, polarization, dextrans in case of introduction of membrane and chromatograp hic technologies.
