“…The intrinsic viscosity data can be compared in Table 1. In Figure 3 the application of Martin's method is observed, the calculation of the intrinsic viscosity accounts for an ER% of 1.55%, but R 2 =0.9326; in similar works such as Roven'kova et al [49,50] comparative and detailed studies were made of different graphical methods for the calculation of the intrinsic viscosity in which they conclude that the Martin and Budtov methods are suitable for synthetic polymers used. One of the problems that normally involves the Kraemer method is its slope and also its R 2 approximately equal to zero, which is why it is not taken as a reference to compare against other methods.…”

The chia (Salvia hispanica) generates an abundant and viscous mucilage, this is purified with periods of heating-cooling and finally precipitated with ethanol, obtaining chia gum, CG. In this work the intrinsic viscosity is determined by different methods being Huggins taken as standard. The different methods are compared and evaluated with their respective percentage relative errors. By means of intrinsic viscosity is determined the molecular weight with a value of 3846000g/mol. This polysaccharide acquires a rod-like conformation with an "a" value, Mark-Houwink parameter, of 0.803 according to Int. J. Biological Macromol. 81 (2015) 991-999. This macromolecule is very promising and has a potential in several industrial applications such as film forming, gel, thickener, and coemulsifier.
