Abstract
This invention relates to methods of increasing the viscosity of a dispersion containing an alginate by subjecting the dispersion to high shear, such as the shear in a laboratory valve homogeniser. The viscosity of the dispersion increases within the range of two fold to five hundred fold. The method of increasing viscosity is useful in tobacco reconstitution or tobacco substitut processes, especially where either low levels of binder are required or improved taste characteristics over cellulosic binders, for example, are important.
