Properties: white powder; relative density 1.86; soluble in water, insoluble in ethanol; its aqueous solution hydrolyzes to phosphoric acid when heated with dilute inorganic acids; it is hygroscopic and forms six crystalline hydrates upon absorbing water; it decomposes to sodium metaphosphate when heated above 220°C. Use: Used as a leavening agent in baked goods to control the rate of fermentation ； Used in instant noodles to reduce the rehydration time of the finished product, preventing sticking and disintegration ； Used in biscuits and pastries to shorten fermentation time, reduce product damage, create uniform air pockets, and extend shelf life.
