TL;DR: In this paper, the gum polysaccharide of Acacia senegal, the main source of gum arabic, has been re-examined by means of two series of sequential Smith degradations, one starting with the whole polysacchide, the other with a product from which all acid-labile side-chains had been removed by prior partial hydrolysis.

TL;DR: In this article, the effects of adding GA (0.1-1.0%) on solubility, pasting, and rheological properties of 5% native tapioca starch (TS) were analyzed.
Abstract: Gum arabic (GA) is a fairly inexpensive gum and is well known for its stabilizing, emulsifying, and thickening properties. The effects of adding GA (0.1–1.0%) on solubility, pasting, and rheological properties of 5% native tapioca starch (TS) were analyzed. Dynamic viscoelasticity measurements showed that the elastic modulus (G′) and the viscous modulus (G″) increased in the presence of GA, suggesting a strong interaction between GA-TS in the composite system. All concentrations of GA resulted in higher elasticity (G′ > G″). Pasting properties revealed that the peak viscosity and setback of the TS-GA dispersion decreased with increasing concentration of GA, suggesting the importance of GA in controlling overall viscosity. The flow behavior index (n) decreased from 0.99 to 0.23 as the concentration of GA in the dispersion increased, indicating pseudoplastic behavior (n

TL;DR: In this paper, the interfacial rheology of polysaccharide adsorption layers of corn fiber gum (CFG), octenyl succinate anhydride-modified starch (OSA-s), gum arabic (GA) and soybean solvers (SSPS) at the oil/water interface and their emulsifying properties in oil-in-water (O/W) emulsions were compared.
