High‐Efficient Preparation of Carboxymethyl Starch via Ball Milling With Limited Solvent Content

Abstract: Carboxymethyl starch (CMS) is successfully prepared via ball milling in the presence of limited amounts of solvent, monochloro acetate, or dichloroacetic acid. In the process, several factors affecting carboxymethylation reaction such as solvent, NaOH/ClCH2COONa ratio, ClCH2COONa/anhydroglucose unit (AGU) ratio, reaction time, and amount of dichloroacetic acid are investigated in terms of the degree of substitution (DS) for the CMS and the optimum conditions are established. Under this condition, the substitut… Show more

“…[ 14 ] Up to now, the modification methods of starch include physical modification, chemical modification, and biological modification. [ 15 ] Chemical modification as the most common method also includes esterification, [ 15,16 ] etherification, [ 17,18 ] oxidation, and grafting. [ 19 ] Sodium carboxymethyl starch (CMS), as one of the etherified starch, is most commonly used in drilling muds.…”

“…The composition and structure of the genetic improvement have resulted in improved physicochemical properties and functional properties of the starch, and the new starch without subsequent chemical treatment has great potential for application. [5,6] In recent years, many novel potato starches with improved starch properties have been obtained by inhibiting the expression of some key genes involved in starch biosynthesis or the expression of foreign genes in plants. Overexpression of PDXII gene under the control of a constitutive promoter enhanced the accumulation of the vitamin B6 which also augmented the tolerance under various abiotic stresses in potato.…”
