How it works

Antimicrobial action:

Calcium propionate works by interfering with the ability of microorganisms to reproduce, preventing them from generating the energy they need to grow.

Does not require acidity:

Unlike some other preservatives, such as benzoates, propionates do not require an acidic environment to be effective.

Safety profile:

Calcium Propionate is a non-toxic, generally recognized as safe (GRAS) substance. It is rapidly absorbed and metabolized in the human body and does not accumulate. Although very safe, it may cause mild irritation in sensitive individuals with long-term or excessive exposure. It is considered environmentally safe and biodegradable.

Storage requirements:

Keep the product dry
Relative humidity <50%
Protect product against influences of weather and contamination

Transport & Packaging:

Calcium Propionate for industrial and food applications is supplied in moisture-proof packaging.
It can be packaged in various forms: 25kg bags, 500kg or 1000kg jumbo bags.
