Calcium Propionate CAS:4075-81-4
Food additives Preservative Calcium Propionate Calcium propionate CAS:4075-81-4 is white crystalline granule or crystalline powder. Odorless or slightly propionic acid odor, hygroscopic, soluble in water, insoluble in alcohol. Specification: Calcium propionate Anhydrous pharma grade Calcium propionate Monohydrate Industrial grade Calcium propionate Monohydrate Food grade FCC Calcium Acetate Monohydrate Pharma E281 * Please refer to Certificate of Analysis for lot specific data. Application: 1) The bacteriostatic effect of calcium propionate liquid wet acid preservative is affected by PH of environment. The minimum inhibitory concentration was 0.01% at PH5.0 and 0.5% at PH6.5. In acidic medium, it has strong inhibition effect on all kinds of molds, aerobic bacillus or gram-negative bacillus. It has special effect on preventing the production of aflatoxin, but has almost no effect on yeast. In addition, it also acts as a preservative for food. 2) Used as food preservative and mildew prevention agent, it has extensive inhibitory effect on mold, yeast and bacteria 3) Used as an analytical reagent 4) Calcium propionate is also an acid food preservative whose bacteriostatic effect is affected by the Ph of the environment. The minimum inhibitory concentration was 0.01% at Ph 5.0 and 0.5% at Ph 6.5. In acidic medium, it has strong inhibition on all kinds of molds, Gram-negative bacillus or aerobic bacillus. It has special effect on preventing the production of aflatoxin, but has almost no effect on yeast. In the food industry, mainly used in vinegar, soy sauce, bread, pastries and soy products, the maximum use (propionic acid, the same below)2.5g/kg; The maximum usage in raw wet products is 0.25g/kg. Can also be used as feed mildew prevention agent. 5) Used as preservative for breads, pastries and cheeses, and as a mildew inhibitor for feed. As a food preservative, calcium propionate is mainly used in bread because sodium propionate raises the ph of bread and delays the fermentation of raw noodles. Sodium propionate is often used in pastries because the leavening of pastries is done with a synthetic leavening agent and there is no yeast development problem caused by pH rise. As a feed preservative, sodium propionate is better than calcium propionate. But calcium propionate is more stable than sodium propionate. Propionate in food in addition to bread, pastry, cheese, etc., can also be used in soy sauce to prevent mildew, inhibit re-fermentation. In medicine, propionate can be used as a powder, solution and ointment to treat diseases caused by parasitic molds of the skin. Ointment (liquid) contains 12.3% sodium propionate, powder 15% calcium propionate.
