We have recently developed an FT-Raman spectroscopic method for measuring the amount of chemical modification of starch samples from a diverse range of botanical sources and amylose contents. In this paper, we present results and FT-Raman spectroscopic calibration curves that can be used to measure the degree of chemical modification for starches that have been acetylated, succinylated, cationic modified, and maleic acid modified. The FT-Raman methodology we have developed is much faster than currently used wet chemistry techniques, is nondestructive of the sample, needs almost no sample preparation, does not require use of hazardous chemicals, and can be further developed for use as a quality control method for process control in manufacturing.
