Calcium Propionate

CAS No.: 4075-81-4
Appearance: White crystalline powder or free-flowing granules, faint characteristic odour
pH: 7.0 - 9.0 in 10% aqueous solution
Calcium content: 18% min

Calcium Propionate, CAS 4075-81-4, is a white crystalline powder or free-flowing granule, highly soluble in water and weakly alkaline at pH 7.0-9.0 in 10% solution. It works by penetrating microbial cell walls to inhibit mould and yeast, and it is approved by FAO/WHO and FCC. Two things separate it from sodium propionate: it supplies at least 18% calcium instead of sodium, and it is heat resistant to 150 deg C, so it survives baking and automated dosing without breaking down.

Why buyers specify this grade

Dual-action preservation against both mould and yeast, extending food and feed shelf life by 30% to 100%
Supplies calcium at 18% min, replacing sodium propionate to reduce sodium intake
Heat-resistant to 150 deg C and low-dust granules compatible with automated production
Powder at 80-200 mesh and granules at 14-60 mesh for liquid or dry blending systems
Certified for ISO 22000 for food, FAMI-QS for feed, Halal and Kosher

Where it is used

Powder in bakery, dairy and sauces for instant dissolution and even protection
Granules in flour, premixes and dehydrated foods for low dust and auto-dosing
Ultrafine powder in aquatic feed and premixes for high bioavailability
Low-dust granules in poultry and livestock feed for slow release that protects nutrients

Who buys it

Industrial bakeries and flour mills
Dairy and sauce manufacturers
Aquafeed and premix producers
Poultry and livestock feed mills

Problems it solves

Sodium load in a product where the nutritional label is under pressure
Dust in automated dosing systems, addressed by the low-dust granule
Preservative breaking down during baking, avoided by heat resistance to 150 deg C
Uneven protection in a liquid system, addressed by the instant-dissolving 80-200 mesh powder

Packing and options

Powder 80-200 mesh for liquid or instant-dissolution systems
Granules 14-60 mesh for dry blending and automated dosing
Ultrafine powder for aquatic feed and premixes
Low-dust granules for poultry and livestock feed

How it compares

Against sodium propionate, calcium propionate adds calcium rather than sodium, tolerates 150 deg C and comes in a low-dust granule for automated lines. Sodium propionate dissolves faster in cold systems. Within this product, the mesh choice is the real decision: powder for instant even protection, granules for dust-free auto-dosing and slower release.

Handling and storage

Choose 80-200 mesh powder for bakery, dairy and sauces where instant dissolution is needed
Choose 14-60 mesh granules for flour, premixes and dehydrated foods on automated dosing
In aquatic feed use the ultrafine powder for bioavailability; in poultry and livestock feed use the low-dust granule
Store dry and sealed, keeping granules free flowing

FAQ

Calcium Propionate questions buyers ask

How much does it extend shelf life

It inhibits both mould and yeast, extending the shelf life of food and feed by 30% to 100%.

Which mesh sizes are available

Powder at 80-200 mesh and granules at 14-60 mesh, plus an ultrafine powder for aquatic feed and low-dust granules for poultry and livestock feed.

What certifications does it carry

Certified for ISO 22000 for food and FAMI-QS for feed, plus Halal and Kosher, and it is approved by FAO/WHO and FCC.

Is it heat stable for baking

Yes, it is heat-resistant to 150 deg C and the low-dust granules are compatible with automated production.

How much calcium does it supply

18% min calcium, which lets it replace sodium propionate where sodium intake needs to be reduced.

What is the pH in solution

7.0 to 9.0 in a 10% aqueous solution, weakly alkaline.

How does it inhibit spoilage

It penetrates microbial cell walls to inhibit mould and yeast growth.
