Gellan gum is the extra-cellular polysaccharide produced by the Gram-negative bacteria-pseudomonas elodea that is separated from water lily, and is one of the microbia polysaccharides full of the development prospect in the recent years. Gellan gum is a high molecular weight polysaccharide (i.e., complex sugar) gum produced as a fermentation product by a pure culture of the microbe Sphingomonas elodea. The production organism is an aerobic, well characterized, non-pathogenic, gram-negative bacterium. The general chemical structure of gellan gum is presented. Its structure consists of four linked monosaccharides (i.e., simple sugars), including one molecule of rhamnose (a sugar found in various plants), one molecule of glucuronic acid (an oxidized glucose molecule), and two molecules of glucose (a component of sucrose, which is common sugar). The exact molecular formula of gellan gum may vary slightly (e.g., depending on the degree to which the glucuronic acid is neutralized with various salts.
CAS: 71010-52-1

Properties
Gellan gum is a water soluble, off-white powder. It has a molecular weight greater than 70,000 daltons with 95 percent above 500,000 daltons. It forms gels when positively charged ions (i.e., cations) are added. Thus, the thickness and texture of gellan gum in various products can be controlled by manipulating the addition of potassium, magnesium, calcium, and/or sodium salts. In the same way, its melting temperature can be modified to either be below or above 100° C.

Uses:
Gellan gum is a food additive that acts as a thickening or gelling agent, and can produce gel textures in food products ranging from hard and brittle to fluid. Types of products that typically contain gellan gum include: bakery fillings, confections, dairy products, dessert gels, frostings, icings and glazes, jams and jellies, low-fat spreads, microwavable foods, puddings, sauces, structured foods, and toppings.
Gellan gum also can be used in lotions and creams, make-up, face masks and packs, hair care products, toothpaste, and air freshener gels. Gellan gum also may be used in canned cat and dog food.
Packing: 25kg/drum or as your request.
Storage Situation: Stored in a cool and dry well-closed container. Keep away from moisture and strong light/heat.
Shelf Life: Two years when properly stored.
Delivery: Within two weeks after receiving your prepayment.
