Thickener: Carboxymethylcellulose

Carboxymethylcellulose (CMC) is a common food additive used as a thickener and stabilizer. It is derived from cellulose, a natural polymer found in plant cell walls, and is chemically modified to make it soluble in water. This process results in a white, odorless powder that dissolves easily in liquids.

Manufacturers add CMC to foods to improve texture and prevent ingredients from separating. It helps thicken sauces, dressings, and baked goods, and can also be found in ice cream and beverages. In baked goods like breads and buns, it helps retain moisture and improve softness.

Carboxymethylcellulose is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food. It is not absorbed by the body and passes through the digestive system unchanged, meaning it typically does not contribute calories. International bodies like JECFA (Joint FAO/WHO Expert Committee on Food Additives) have evaluated CMC and found it safe for consumption.
