Xanthan Gum And Sodium Citrate

Xanthan gum is a polysaccharide, a type of carbohydrate, produced by the fermentation of sugar by the bacterium *Xanthomonas campestris*. Sodium citrate is the sodium salt of citric acid, a weak acid found naturally in citrus fruits. It is produced commercially by the neutralization of citric acid with a sodium base.

Xanthan gum is used as a thickener and stabilizer in foods like salad dressings, sauces, and baked goods, preventing ingredients from separating. Sodium citrate is used as a flavoring agent and to control acidity in products such as jams, jellies, and ice cream. It can also help prevent spoilage.

Xanthan gum is generally recognized as safe (GRAS) by the FDA. It is poorly digested and may have a mild laxative effect in very large amounts. Sodium citrate is also GRAS. It is used in small amounts as a food additive. JECFA and EFSA have evaluated both ingredients and established acceptable daily intakes.
