Synthesis and characterization of sodium carboxymethylcellulose from cavendish banana pseudo stem (Musa cavendishii LAMBERT)

Alkalization using 15% NaOH and etherification using 1.2 g (w/w) NaMCA gave CMC the highest degree of substitution (DS), viscosity, purity and crystallinity, i.e. 0.75; 4033 cps; 98.23 and 38.33% respectively.
