What Is Sodium Aluminum Phosphate (SALP)?
A leavening acid used in baking powders, self-rising flour, and processed cheese. It reacts with baking soda to produce carbon dioxide gas, which makes baked goods rise. Also used as an emulsifying agent in processed cheese products.
Mechanism of Action
SALP releases aluminum ions during digestion. While aluminum is poorly absorbed from the GI tract (less than 1%), chronic aluminum exposure has been studied in relation to neurodegenerative diseases. EFSA set a tolerable weekly intake (TWI) for aluminum of 1 mg/kg body weight/week, and noted that dietary aluminum from food additives is a significant contributor to total exposure.
Why People Avoid Sodium Aluminum Phosphate (SALP)
Contains aluminum — concerns about neurotoxicity and links to Alzheimer's (debated)
EFSA found dietary aluminum from additives may exceed safe weekly intake
Aluminum accumulates in the body over time
Aluminum-free baking powder alternatives are widely available
Regulatory Status
🇺🇸 FDA
FDA-approved as GRAS (21 CFR 182.1781). No specific limit on aluminum content in food. FDA does not restrict total dietary aluminum from food additives.
🇪🇺 EFSA
EFSA set a TWI of 1 mg/kg body weight/week for aluminum in 2008. EFSA noted that dietary exposure to aluminum from food additives (including SALP, E541) likely exceeds the TWI in a significant proportion of the European population.
Regulatory Timeline
• 1960s — Widely adopted in commercial baking powders
2008EFSA establishes TWI for aluminum and flags food additive contribution
2011JECFA revises provisional TWI to 2 mg/kg body weight/week
