“…Previously, it was reported that preparing carboxymethyl cocoyam starch at 70 O C caused starch gelatinization [13]. Increase in the DS with temperature as observed here is consistent with the carboxymethylation of mungbean starch [7].…”

Starch isolated from an under-utilized legume plant (pigeon pea) was carboxymethylated.Influences of reaction parameters were investigated on the degree of substitution (DS) and the reaction efficiency (RE). Studies showed that optimal DS of 1.12 could be reached at reaction efficiency of 80.6 % in isopropanol-water reaction medium (40 o C, 3h). The scanning electron microscopy showed that after carboxymethylation, the granular appearance of the native starch was distorted. Wide-angle X-ray diffractometry revealed that crystallinity was reduced significantly after carboxymethylation. The infrared spectra revealed new bands in the carboxymethyl starch at ν =1600, 1426 and 1324 cm -1 and they were attributed to carbonyl functional groups vibration, -CH 2 scissoring and OH bending vibration respectively. Broad band 13 C NMR of carboxymethyl starch showed intense peak at δ = 180.3 ppm and it was assigned for carbonyl carbon on the carboxymethyl substituent on the AGU (Anhydroglucose Unit). DEPT (Distortionless Enhancement by Polarization Transfer) 135 NMR showed negative signals which correspond to methylene carbons on the AGU. The differential scanning calorimetry (DSC)suggests loss of crystallinity after carboxymethylation. Thermogravimetry (TG), Derivative Thermogravimetry (DTG) and Differential Thermal Analysis (DTA) show that thermal stability improved after carboxymethylation. The study provides information on the preparation and characterization of a biomaterial from a new source which could be used alone or in the preparation of other functional polymers for diverse polymer applications.2

“…Carboxymethyl starch is cold water soluble material giving viscous, colourless and transparent solutions. It could be applied in food, medicine, pharmacy 60, textile 61 and paper sizing, printing, electrodes, ceramics (http://www.modifiedstarchproducts.com/), drilling fluids 62, as corrosion inhibitors 63 or electrorheological fluids 55, 59. However, they mostly correspond to CMS of low DS (below 0.4), as mainly such products are commercially available.…”

Carboxymethyl starch (CMS) could find application in many areas of industry. A review of synthesis methods of medium and high substituted CMS was presented. The influence of synthesis parameters on degree of substitution (DS) as well as reaction efficiency was described. The methodology of CMS physicochemical properties determination as well as the relation between CMS chemical characteristics (e.g. DS, amylose/amylopectin ratio) and its physicochemical properties was presented. Moreover, reported CMS applications were submitted.

“…In addition to cellulose, polysaccharides such as starch (Kittipongpatana, Chaichanasak, et al, 2006), inulin (Verraest, Peters, Batelaan, & van Bekkum, 1995), and xylan (Petzold, Schwikal, & Heinze, 2006) have also been successfully carboxymethylated. However, the reaction conditions for the carboxymethylation process vary among different types of polysaccharides, and thus it was pertinent to optimize the carboxymethylation process specifically for carrageenan.…”
