Xanthan Gum

Wide range of applications:

Bottled foods / bakery foods / dairy products

Xanthan Gum

Xanthan gum is a natural polysaccharide produced by the fermentation of Xanthomonas campestris. It is usually found in the form of a white or pale yellow powder and is widely used as a thickener, stabilizer, and emulsifier in the food, cosmetic, and industrial fields.

Introduction To The Powerful Application Of The Xanthan Gum

Xanthan gum is a commonly used thickener and emulsifier in food additives, used to improve the shape and sensory properties of food. It is widely used in bakery foods, dairy products, frozen foods, salad dressings, beverages, brewing, confectionery, and pastry flavorings.

The Difference Between Xanthan Gum, Sodium Alginate, and

Sodium Carboxymethyl Cellulose:

1. Different Applications

Xanthan Gum

High-salt/high-temperature systems: sauces, salad dressings, pickled foods, high-salt beverages.
Suspension stability: fruit juices and pulps, liquid fertilizers, pigment suspensions.
Dairy products: yogurt, ice cream (anti-ice crystal formation, shape retention).

Sodium Alginate

Heat-Irreversible Gels: Popping beads, biomimetic jellyfish/caviar, vegetarian capsules, edible films.
Special Textures: Low-sugar jellies, puddings, and gluten enhancers for pasta products.
Microcapsules/Encapsulation: Probiotics, flavorings, and sustained-release active ingredients.

Sodium Carboxymethyl Cellulose

Basic thickening: Inexpensive beverages, ice cream, bread, noodles (moisture retention and gluten enhancement).
Film forming/coating: Moisture-proofing for candied fruits, tablet coating, paper sizing.
Daily chemical/industrial: Detergent thickening, toothpaste, papermaking, textile sizing.

2. Basic Information Comparison: Xanthan Gum, Sodium Alginate, and Sodium Carboxymethyl Cellulose

Xanthan gum, sodium alginate, and sodium carboxymethyl cellulose (CMC) are all commonly used water-soluble thickeners/stabilizers, but they differ significantly in their source, molecular type, solubility, and typical pH stability. Refer to the table below compiled by Polifar for detailed information.

Properties	Xanthan Gum	Sodium Alginate	Sodium carboxymethyl cellulose (CMC)
Origin	Microbial fermentation (Xanthomonas aurantiacus)	Extracted from natural brown algae (kelp/giant kelp)	Chemically modified from natural cellulose (cotton/wood)
Molecular Type	Anionic heteropolysaccharide (branched)	Anionic linear polysaccharide (mannuronic acid + guluronic acid)	Anionic cellulose ether derivative
Solubility	Swells rapidly in cold water, prone to clumping, requires high-speed stirring	Soluble in cold water, dissolves slowly, easily dispersed	Soluble in cold water, easily dispersible, higher degree of substitution improves salt tolerance
Typical pH Stable	Stable over a very wide pH range of 2–12	Stable at pH 4–10, easily gels/precipitates under strong acid conditions	Stable at pH 4–11, highest viscosity at pH 7
