Calcium propionate

What you need to know

Calcium propionate stops mould growing in bread and baked goods, keeping them safe and fresh for longer.

Propionates also occur naturally in some cheeses. A few small studies have explored a possible link with irritability or disturbed sleep in some sensitive children, but the evidence is limited and not settled.

Regulators consider it safe; it is one of the most common bread preservatives.
