4 important questions on Selection of Polysaccharides

Which polysaccharides are vulnerable to different shear rates and which are not?

Vulnerable --> CMC, HEC (hydroxypropylethyl cellulose) --> decrease the viscosity when shear rates are applied

Not vulnerable --> gum arabic --> keeps stable viscosity at different shear rates
