This prevents the breakdown of dietary starches into glucose, allowing in the end that carb from starch to pass through the system unchanged. According to these studies the Chitosan viscosity is mainly dependent on average molecular weight of Chitosan itself. Chromatography together with technique of light scattering detection is the best possible way of determining this molecular weight.
