Dicalcium Diphosphate (E540): What It Is and Is It Safe?
Dicalcium diphosphate is a calcium salt of diphosphoric acid used as a buffer, emulsifier and raising-agent acid. Like other di- and polyphosphates it adds to total dietary phosphate intake, for which EFSA set a group acceptable daily intake of 40 mg phosphorus per kg body weight per day in 2019. EFSA linked high phosphate intake to effects on kidney function and estimated that intake may exceed the ADI in infants, toddlers and children, while epidemiological studies associate high phosphate-additive loads with cardiovascular risk.
