Powder Cellulose

Powdered cellulose is a purified form of cellulose, a fiber that makes up the cell walls of plants. It is typically made from wood pulp or cotton linters. The cellulose is mechanically processed and purified to create a fine white powder.

Manufacturers add powdered cellulose as an anti-caking agent to prevent powders from clumping together, and as a source of dietary fiber. It is commonly found in shredded cheeses, powdered sugar, and baked goods.

In the US, powdered cellulose is generally recognized as safe (GRAS) by the FDA for use as an anti-caking agent and fiber source. It is indigestible and passes through the body, adding bulk to food. JECFA and EFSA have evaluated cellulose and its derivatives. Evidence does not suggest adverse health effects from consuming typical amounts.
