Application
1. Baking & Leavening Systems
Primary application as a leavening acid in:
● Baked goods: cakes, muffins, pancakes, doughnuts, and quick breads
● Refrigerated doughs: biscuits, crescent rolls, and pizza crusts
● Baking powders: used in double-acting baking powder formulations
● Offers controlled gas release for optimal volume, texture, and crumb structure
2. Processed Meat & Poultry
Acts as a phosphate additive to:
● Improve water-holding capacity and yield
● Enhance texture and juiciness
● Prevent discoloration in products such as:
● Franks and sausages
● Ham and cured meats
● Ground meat patties
3. Potato Products
Used as a color retention agent in:
● French fries — prevents after-cooking darkening
● Dehydrated potatoes and mashed potato flakes
● Canned potatoes
● Functions by chelating iron ions that would otherwise cause discoloration
4. Seafood Processing
Applied in canned tuna, shrimp, and surimi to:
● Retain natural color
● Bind moisture
● Prevent struvite (magnesium ammonium phosphate) crystal formation
