Physicochemical Characterization of Seed Gum from Cassia Fistula

Cassia fistula gum was purified and modified by isopropanol precipitation and carboxymethylation process respectively. The physicochemical property of both purified and modified gums were evaluated and compared to their crude gum. The mannose to galactose (M/G) ratio of purified gum was altered by purification process. While, the carboxymethyl groups were formed via carboxymethylation for modified gum, indicated by IR spectra. As expected, the physicochemical properties of both purified and modified gums were better than crude gum.
