In the ever-evolving landscape of materials science, the pursuit of sustainable and high-performance materials has led to a renewed interest in biopolymer composites. These materials, which blend the natural advantages of biopolymers with the enhanced properties of composite structures, present a promising frontier for innovation across various ...

Xanthan–galactomannan interactions as related to xanthan conformations
International Journal of Biological Macromolecules, 1998The influence of xanthan conformation on the physicochemical behaviour of their mixtures with galactomannan from Schizolobium parahybae mannose:galactose ratio (M/G=3), was studied by viscoelastic measurements, differential scanning calorimetry (DSC) and chiroptical (circular dichroism) methods. The results suggested a more effective interaction of the

Food Hydrocolloids, 2003
Abstract Xanthan solutions have gel-like properties, including the ability to hold particles in suspension, but the network structure breaks down readily, allowing the solutions to flow freely. These ‘weak gel’ properties are attributed to tenuous association of ordered chains, and are enhanced by cations, particularly Ca2+.

Multistranded Helix in Xanthan Polysaccharide
Science, 1977The extracellular polysaccharide xanthan is shown by electron microscopy to be an unbranched, probably double-stranded fiber 4 nanometers wide and 2 to 10 micrometers long when native. Denaturation yields a single strand only 2 nanometers wide and 0.3 to 1.8 micrometers long.

Role of conformation and acetylation of xanthan on xanthan-guar interaction
Carbohydrate Polymers, 1992Abstract The synergistic effect obtained by mixing xanthan and guar solutions were examined by low shear viscosity measurements in relation to the temperature. Native and deacetylated xanthan samples were used in mixtures in which the total polymer concentrations were 1 g/litre and 0·5 g/litre.

Xanthan Biopolymer Semipilot Fermentation
Society of Petroleum Engineers Journal, 1981Abstract Using standard microbiological techniques in a semipilot plant-scalable fermenter, xanthan-specific culture techniques developed by the U.S. Dept of Agriculture's Northern Regional Research Laboratory (NRRL) were used at Marathon Oil Co.'s Denver Research Center (DRC) to obtain improved and reproducible high conversions and ...

Abstract Gelatin (G) and xanthan gum (X) formed complexes either on bringing their blends to pH 2.3 or carrying out the electrode process in aqueous blends of X and G at pHs from 9 to 11. X carboxylic groups and G peptide moieties were involved in the interactions between the partners.
