What it is

Calcium alginate is a salt derived from alginic acid, which comes from brown seaweed. It is produced by reacting alginic acid with a calcium salt.

Why it's used

Manufacturers add calcium alginate to foods as a stabilizer and thickener. It helps improve texture and prevent ingredients from separating. You can find it in baked goods, frozen foods, and some dairy products.

Health notes

Calcium alginate is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA). It is a source of dietary fiber. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated calcium alginate and established an acceptable daily intake.

Allergen info

Calcium alginate is derived from seaweed and is not one of the nine major allergens. It does not contain gluten.
