Chemical properties
White or cream to light brownish yellow powder. It can be dispersed in hot or cold water with a pH of 4.0~7.0 and forms a high viscosity solution. Heating and mechanical agitation increase solubility. If a moderate amount of alkali is added to the solution, a heat stable gel which does not melt even when heated is formed.
Light yellow to brown powder. Basically odorless and tasteless. The aqueous solution has a strong tailing (drawing) phenomenon and a high consistency. It has a certain ability to decompose fibrous materials. Soluble in water, insoluble in ethanol and oil. The main component is polysaccharides.
Use
Gelling agent; thickener; emulsifier; stabilizer; film former.
