E401 Algin Sodium Alginate
What is Algin Sodium Alginate?
Algin Sodium Alginate, also called sodium alginate, is a natural polysaccharide extracted from brown algae. The aqueous solution of sodium alginate has a high viscosity and is used as a thickener, stabilizer, emulsifier, etc. in the food industry, pharmaceuticals and other industries.

Is Algin Sodium Alginate Safe?
In the U.S.
In the U.S., Algin sodium alginate is a non-toxic food and was included in the U.S. Pharmacopoeia as early as 1938.
Sodium alginate is generally recognized as safe (GRAS) as designated by the FDA.
It is a designation that a specific substance or ingredient is generally considered safe by experts, and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements. Sodium alginate is perfectly safe for using as food additives.
In the EU
Sodium alginate is a high-molecular-weight polymer naturally occurring in brown algae.
The additive is intended to be used as a technological additive (functional groups: thickeners and gelling agents).
The use of sodium alginate in animal nutrition is considered safe for the consumers and the environment.
From EFSA.
In China
In China, the quality standard of sodium alginate is GB1886.243-2016.
It was shown that the intake of high concentrations of sodium alginate for 23 consecutive days had no effects other than those usually associated with polysaccharide bulking agents;
in particular, sensitive indicators of enzymatic and other adverse toxicological effects remained unchanged.
