Carboxymethyl derivatives of kappa-carrageenan (KC) with varying degrees of substitution
were obtained by multi-step carboxymethylation process. The structural and chemical …

Chemical modification of polysaccharides is an important route to enhance, develop or
change polysaccharide properties. In this study, carboxymethylation of kappa-carrageenan …

In order to develop a wound healing material possessing anticoagulant activity,
antimicrobial activity and moisture absorbability and moisture-retention capacity …

Commercial kappa-and iota carrageenans were cationized with 3-chloro-2-
hydroxypropyltrimethylammonium chloride in aqueous sodium hydroxide solution. For …

In order to study the relationship between chemical structure and properties of modified
carrageenans versus antioxidant activity in vitro, κ-carrageenan oligosaccharides were …

New amphiphilic derivatives of kappa-carrageenan (KC) were synthesized by hydrophobic
modification with octyl chloride. Two different methods based on microwave and …

In this work, the physicochemical properties of maleic anhydride (MAH)-modified κ-
carrageenan (κCar)(MC) were characterized and compared with those of native κ …

Degradation of polysaccharides to afford low-molecular-weight oligosaccharides have been
shown to produce new bioactivities that are not present in the starting material. The …

κ-Carrageenan is a linear, sulphated polysaccharide that is widely used in the food industry
as a gelling agent due to its lack of toxicity and biocompatibility. In this study, the …

Kappa-carrageenan (KC) esterification reaction with octenyl succinic anhydride was
optimized using response surface methodology, leading to the production of a food-based …
