White crystalline solid or powder.
Calcium propionate is used in bakery products as a mold inhibitor.
Propionates prevent microbes from producing the energy they need,
unlike benzoates, propionates do not require an acidic environment.
often used as an anti-fungal agent. Calcium is often preferable
to sodium, both to reduce sodium levels in the diet, but also because
calcium ions are necessary for the enzyme α-amylase
to act on the starches in bread, making them available for the
yeast, and improving the texture of the bread. Stale bread is
caused by the starch amylose
The enzyme α-amylase
converts some of this starch
to sugars, preventing the recrystallization.
