What it is
Kelp extract is a substance derived from various types of seaweed, particularly brown algae. It is typically produced by extracting soluble components from the kelp, often using water or alkaline solutions, and then concentrating the liquid.
Why it's used
Manufacturers use kelp extract primarily as a source of alginates, which act as thickening and gelling agents. It can also contribute a subtle umami flavor. You'll find it in foods like sushi, pickles, and savory snacks.
Health notes
Kelp extract is generally recognized as safe (GRAS) by the FDA for use in food. It is a natural source of iodine, which is essential for thyroid function. Excessive iodine intake can have negative health effects, but typical consumption from kelp extract in foods is unlikely to cause harm. JECFA has evaluated alginates derived from kelp and established specifications for their use.
Allergen info
Kelp extract is not derived from any of the 9 FDA major allergens. It does not contain gluten.
