SODIUM CARBOXYMETHYL STARCH (CMS or SCMS) is a starch ether derivative derived from starch. It is soluble in water at room temperature and forms a transparent to light milky and viscous solution. CMS is an important modified starch with unique properties due to the presence of negatively charged functional group (CH2COO-). The introduction of carboxymethyl groups interrupts the ordered structure of native starch and intervenes with the re-association of gelatinized starch. This modification yields[...]
