Food Grade Sodium Acid Pyrophosphate
white monoclinic crystal powder. Its relative density is 1.86. It is soluble in water, insoluble in alcohol. It hydrolyzes to orthophosphate when heated in acid medium. It is hygroscopic, forms hexahydrate in damp air, and decomposes to metaphosphate at above 220℃
In 25kg composite plastic woven/paper bag with PE liner.
Storage and transport:To be stored in a dry, ventilate and clean warehouse; Valid for two years.
In food industry, it is used as rapid ferment agent, quality improver and applied as acid component of bread and cake’s synthetic leavening agent. Mixed with other phosphates can be applied to water retention of meat product, such as canned meat, cooked ham, meat can and instant noodles.
Commonly, we add this product according to the proportion of 0.2-0.5%.
It can be adjustable according to the actual situation.
