奇亚（西班牙鼠尾草）产生丰富而粘稠的粘液，经过反复加热-冷却的纯化，最后用乙醇沉淀，得到奇亚胶，CG。在本工作中，以哈金斯为标准，用不同的方法测定了特性粘度。对不同方法进行了比较和评价，并给出了各自的相对误差百分比。通过特性粘度测定其分子量，其值为3846000g/mol。该多糖获得棒状构象，其“a”值（Mark-Houwink参数）为0.803。[j] .中国生物医学工程学报，2011(5):391 - 391。该大分子在成膜、凝胶、增稠剂和共乳化剂等工业领域具有广阔的应用前景。
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.
