    China gellan gum powder water-soluble gellan gum white powder

    Gellan gum is a water-soluble anionic polysaccharide produced by the bacterium Sphingomonas elodea (the current taxonomic
    classification.
    It was originally identified as "Pseudomonas elodea" based on the taxonomic classification at the time of
    discovery. the gellan-producing bacterium was discovered and isolated by the former Kelco Division of Merck & Company, Inc. in
    1978 from the lily plant tissue from a natural pond in Pennsylvania, USA. It was initially identified as
    a substitute gelling agent at significantly less use level to replace agar in solid culture media for
    the growth of various microorganisms its initial commercial product with the trademark as "GELRITE" gellan
    gum, was subsequently identified as a suitable agar substitute as gelling agent in various clinical bacteriological media.
    Application:
    (1) Typical foods prepared using gellan gum: Gelled desserts, jam, jelly, pudding, confectionery, sugarcoating
    of confectionery, frost of cake, filling of cake or bread, and other foods, cakes, and pet foods.
    (2) Other applications: Microbiological media, capsules, perfumes, etc.

    Gellan gum is a straight chain polymer that comprises repeating units of glucose, rhamnose and glucuronic acids.
    The native form (High Acyl form) has two acyl substituents, actetate and glycerate, that are located on the glucose residues.
    On average, there is one glycerate per repeat unit and one acetate every two repeat units when both are located on the same glucose residue.
    Deacylated gellan gum (Low Acyl form) is produced industrially from HA gellan gum using an alkaline treatment to remove the acyl groups.
    HA and LA gellan gums have very different textures that are virtually at opposite ends of the hydrocolloid texture spectrum:
    HA gellan gels are soft, elastic and non-brittle
    LA gellan gels are firm, non-elastic and brittle
    Blending of the two is a possibility to produce variable texture systems.
    In general, the properties of blends are controlled by ionic concentration:
    HA form behaviour predominates at low ionic concentrations;
    LA form behaviour predominates as ionic concentration increases.
    Gellan gum systems show excellent stability (heat, acid, base).
