What it is

Agar, also known as agar-agar, is a jelly-like substance derived from red algae. It is processed from the cell walls of certain seaweeds and then dried into strips, flakes, or powder. It is a vegetarian and vegan alternative to gelatin.

Why it's used

Agar is primarily used as a gelling agent, thickener, and stabilizer in food products. Its strong gelling properties make it useful in desserts like puddings, jellies, and custards, as well as in jams, sauces, and some dairy products. It can also be used in vegan cheese and meat alternatives.

Health notes

Agar is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of soluble fiber, which may contribute to digestive health. International bodies like JECFA have evaluated agar and established acceptable daily intake levels. It is not known to cause adverse health effects when consumed in typical amounts found in food.

Allergen info

Agar is not derived from any of the nine FDA major allergens. It does not contain gluten.
