What is Calcium Propionate CAS 4075-81-4?

Calcium Propionate, also called calcium propanoate or the calcium salt of propionic acid, is a white crystalline powder or granules with the formula C6H10CaO4, molecular weight 186.22 g/mol, and EC number 223-795-8. It is used mainly as a food preservative and feed additive.

How does Calcium Propionate prevent mold in bread and bakery products?

In a moist food system it releases propionic acid, which interferes with the energy metabolism of molds, rope-forming bacteria, and some other spoilage microorganisms. Because it does not inhibit yeast activity, it is especially suitable for yeast-leavened products such as bread, rolls, buns, and tortillas.

Why is Calcium Propionate often preferred over sodium propionate in bread?

Calcium Propionate is generally preferred in bread because sodium propionate can raise dough pH and slow yeast fermentation. Calcium Propionate can control mold while having less adverse effect on leavening, and it also contributes bioavailable calcium.

What are the main food and feed applications of Calcium Propionate?

In food it is used in bakery products, cheese, processed dairy, whey products, soy products, and other high-moisture formulations. In animal feed and grain storage it reduces mold growth, helps preserve nutrient quality, and supplies a source of calcium for livestock.

Product Description

Calcium Propionate CAS 4075-81-4 is the calcium salt of propionic acid with EC 223-795-8 and molecular formula C6H10CaO4.

Synonyms: Calcium propanoate; Propionic acid calcium salt.

CAS: 4075-81-4.

Molecular formula: C6H10CaO4.

It is supplied as a white crystalline powder or granules.

It has a molecular weight of about 186.22 g/mol.

It is positioned as a propionic acid salt used for preservation and mold control in moisture-sensitive systems.

It is used in food preservation, especially as a mold inhibitor in bakery and high-moisture products.

It is used as a feed additive to control mold growth, preserve nutrient quality, and supply calcium for livestock.

It is also used in certain industrial materials and grain storage where microbial stability is required.

In moist systems it releases propionic acid, which interferes with the energy metabolism of molds and spoilage organisms without inhibiting yeast activity.

Confirm the required food or feed grade, assay, appearance, and related specifications for the chosen grade.

Check compatibility with the target food, feed or formulation and confirm usage levels comply with local regulations.

Store in tightly sealed, moisture-resistant packaging in a cool, dry, well-ventilated area, away from direct sunlight and excessive humidity.

Keep containers closed to prevent moisture uptake and caking during handling and storage.

Confirm packaging suitable for the powder or granulated form and order quantity, and follow the current SDS.

Confirm grade, packaging, and specification as required.
