Descripción
The acacia caven gum (ACG) is an exudate from Acacia caven tree, this gum is dissolved in water and purified by precipitation with ethanol. In this paper the intrinsic viscosity, [η], is calculated by dissimilar equations, as Huggins, Kramer, Arrhenius-Rother-Hoffmann, Staudinger & Heuer, Square (S), Square root (SR), S-SR average plot, average values of S-SR, and being Kraemer is taken as standard. The different methods are evaluated and compared. From [η] measurements are determined the molecular weight (MV) and hydrodynamic radius (RH), with values of 1060 Kg/mol and 24 nm, respectively. This polysaccharide acquires a random coil conformation with Mark-Houwink parameters of a=0.5507 and k=0.0225 cm3/g. This polysaccharide is applied as thickener, coemulsifier and gelling in different industry.
