In Calcium Alginate Casing

Calcium alginate is a salt derived from alginic acid, which is a natural substance found in brown seaweed. It is produced by reacting alginic acid with a calcium salt. This process creates a gel-like substance that can be formed into casings or other shapes.

Manufacturers use calcium alginate to create edible casings for processed meats like sausages and hot dogs. Its gel-forming properties allow it to hold its shape and provide a smooth texture. It is also used as a thickener and stabilizer in some food products.

Calcium alginate is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of dietary fiber and is not known to have adverse health effects at typical consumption levels. International bodies like JECFA and EFSA have evaluated alginates and found them to be safe.
