Description

Sodium Acid Pyrophosphate (SAPP) is a high-purity inorganic phosphate compound widely used as a leavening acid, buffering agent, and sequestrant. It provides controlled release of leavening gases in bakery products, enhances texture, and improves product stability. SAPP also finds use in food processing, metal treatment, water conditioning, and industrial applications requiring pH control and mineral sequestration.
