Sodium Aluminium Phosphate (SALP)

Sodium Aluminium Phosphate (SALP, FSANZ 541) is a heat-activated slow-acting leavening acid used as the acid component in double-acting baking powder systems, self-rising flour formulations, and dry baking mixes. With 96.6% assay purity, it delivers controlled, reliable CO₂ release during the baking phase not during mixing giving food manufacturers the predictable oven spring and consistent product volume that professional baked goods demand.

Unlike fast-acting leavening acids that exhaust most of their gas during mixing (leaving flat baked goods if the batter sits), SALP is temperature-dependent releasing approximately 75% of its CO₂ when the product enters the oven. This makes it the preferred choice for industrial baking lines, refrigerated and frozen bake-off products, shelf-stable dry mixes, and any application where batter or dough must hold before baking.

• Baking powder manufacture: Primary acid component in double-acting baking powder pairs with sodium bicarbonate and cornstarch for shelf-stable leavening systems
• Self-rising flour & dry mixes: Blended into flour premixes, pancake mixes, muffin mixes, and cake mixes SALP's low moisture reactivity prevents premature gas loss during storage
• Cakes, muffins & cupcakes: Delivers consistent oven spring and fine crumb structure critical for high-volume continuous baking lines where batter may sit in hoppers
• Refrigerated & frozen bake-off product: Ideal for par-baked and frozen doughs SALP remains inactive at refrigerator and freezer temperatures, activating only in the oven
• Biscuits, crackers & cookies: Controlled lift and spread compatible with high-sugar, high-fat formulations
• Processed cheese (emulsifying salt): The phosphate component functions as an emulsifying salt, chelating calcium from casein for smooth processed cheese texture
• Donuts & fried pastry: Consistent internal rise and open crumb during frying compatible with automated depositor systems
