Enhanced gelation properties of purified gellan gum.
Gellan gum is a hydrogel-forming polysaccharide when combined with monovalent or divalent cations such as sodium, magnesium, potassium or calcium. Commercially, gellan gums are sold with trace amounts of these cations, which have been proven to affect the gelation and mechanical properties of the resultant hydrogels. A new method based on impedance analysis for determining the gel transition te...
متن کاملGelation and gel properties of polysaccharides gellan gum and tamarind xyloglucan
Polysaccharide is used widely in food, cosmetic and pharmaceutical industries. The main use is to give appropriate texture to the products. Thus the polysaccharides used in such way are called texture modifier. Here two important texture modifiers, gellan and tamarind xyloglucan are introduced. The former one is a microbial polysaccharide with gelling ability. Gelling ability makes gellan valua...
متن کاملModified Gellan Gum hydrogels with tunable physical and mechanical properties.
Gellan Gum (GG) has been recently proposed for tissue engineering applications. GG hydrogels are produced by physical crosslinking methods induced by temperature variation or by the presence of divalent cations. However, physical crosslinking methods may yield hydrogels that become weaker in physiological conditions due to the exchange of divalent cations by monovalent ones. Hence, this work pr...
متن کاملElectrically conducting PEDOT:PSS - gellan gum hydrogels
Hydrogels consisting of the conducting polymer PEDOT:PSS and the biopolymer gellan gum (GG) were characterized using electrical, mechanical and rheological methods. Compression testing and rheological analysis showed that the gels weakened with increasing PEDOT:PSS content. In contrast, the increasing PEDOT:PSS content resulted in an increasing electrical conductivity. Disciplines Medicine and ...
متن کاملEffects of Potassium Gum Gels Chloride and SodiumChlorideon the Thermal Properties of Gellan
(DSC) for gellan gum gels without and with potassium chloride and sodium chloride were analyzed. The gelling and melting temperatures shifted to higher temperatures with increasing gellan and salt concentration in the concentration range of gellan from O.3 to 2.0% (wlw). The exothermic and endothermic enthalpy increased with increasing ge]lan and salt concentrations. Cooling DSC curves showed o...
