Description
Product Introduction
SAPP – Sodium Acid Pyrophosphate is a functional phosphate ingredient widely used in food and feed processing. Also known as sodium acid pyrophosphate, SAPP works as a leavening acid in combination with sodium bicarbonate, releasing carbon dioxide at a controlled rate to support consistent product rise, texture and crumb structure.
In food formulations, SAPP can also function as an acidity regulator, pH buffer, emulsifying aid and chelating agent. Its controlled reaction characteristics make it suitable for baking powder, self-rising flour, cakes, muffins, pancakes, waffles, biscuits and other chemical leavening systems.
SAPP is also available for feed applications, where it can be used as a preservative and acidity regulator according to the applicable formulation and regulatory requirements.
Wuhan Waking Lion Chemicals Co., Ltd. supplies SAPP in food grade and feed grade specifications, with different packaging options and technical documentation available for B2B customers.

Food Grade SAPP Applications
Baking Powder
SAPP is commonly combined with sodium bicarbonate in chemical leavening systems. The controlled release of carbon dioxide helps provide predictable expansion during baking.
Self-Rising Flour
SAPP can be incorporated into self-rising flour systems together with other leavening components to support convenient baking formulations.
Cakes & Muffins
The controlled reaction characteristics of SAPP can help provide consistent gas release and contribute to the desired volume and crumb structure of cakes and muffins.
Pancakes & Waffles
SAPP can be used in pancake and waffle mixes where controlled leavening is required to achieve consistent product expansion and texture.
Biscuits & Donuts
SAPP is also suitable for applicable biscuit and donut formulations that use chemical leavening systems.
Processed Foods
SAPP may function as an acidity regulator, pH buffer, emulsifying aid or chelating agent in selected processed food formulations.
Processed Seafood Applications
SAPP has chelating properties that can be used in certain processed seafood applications. By interacting with iron and other metal ions, it can help manage unwanted color development in products such as canned shrimp.
The appropriate dosage and processing conditions should be determined according to the specific food formulation, applicable regulations and technical requirements.
Feed Grade Applications
In feed processing, SAPP can be used as a preservative and acidity regulator in applicable feed formulations. Its functional properties can support formulations where control of acidity and preservation characteristics are required.
The appropriate grade, inclusion level and processing method should be determined according to the feed formulation and applicable local regulations.
