What it is

Kombu powder is a dried, powdered form of kombu, a type of edible kelp (seaweed). It is harvested from the sea and then dried and ground into a fine powder. This process concentrates its natural umami flavor and nutrients.

Why it's used

Kombu powder is used as a natural source of umami flavor and to add depth to savory dishes. It is often found in soups, broths, noodle dishes, and seasoning blends. Manufacturers use it to enhance the overall taste profile of food products.

Health notes

Kombu powder is generally recognized as safe (GRAS) by the FDA for use as a food ingredient. It is a source of iodine, and excessive intake of iodine can affect thyroid function. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated kombu and found no safety concerns at typical consumption levels. Evidence does not suggest adverse health effects from consuming kombu powder in amounts typically found in food.

Allergen info

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