Calcium propionate

Evaporation gives the salt sodium acetate, which contains Na+ and CH3COO ions. Many of the salts of carboxylic acids have important uses. Sodium and calcium propionate (Na+ or Ca2+ ions, CH3CH2COO ions) are added to bread, cake, and cheese to inhibit the growth of mold. 

Calcium propionate is used in bakery products as a mold inhibitor. Propionates prevent microbes from producing the energy they need, just as benzoates do. However, unlike benzoates, propionates do not require an acidic environment. 

Calcium propionate is often preferred as an antifungal agent, to reduce sodium levels in the diet, but also because calcium ions are necessary for the enzyme a-amylase to act on the starches in bread,... 

Fumaric acid is used to lower the pH (make something more acidic, which makes it taste more sour). This helps certain antimicrobial agents such as sodium benzoate and calcium propionate work more effectively. Fumaric acid also kills bacteria. 

A dough consists of 83-85% water on a flour basis, with 2% sugar, 1.5% salt, 5 8% yeast with 0.5-0.7% calcium propionate. The problem with this formulation is that it must be soft enough to flow into the cups but to prevent it sticking it must be handled cold around 20°C. 

The mould problem is tackled by using high levels of calcium propionate. This creates problems because it inhibits the yeast. A high level of yeast is used to try and counter this. An alternative way of inhibiting moulds is to spray the muffins with a potassium sorbate solution as they leave the oven. In this case the calcium sorbate is omitted from the dough and the level of yeast is reduced by 1 %.

Calcium Propionate occurs as white crystals or as a crystalline solid. The pH of a 1 10 aqueous solution is between 7.5 and 10.5. One gram dissolves in about 3 mL of water.
