Gellan Gum
{GELUM-HA & GELUM-LA}
(INS 418; CAS No. 71010-52-1)

Gellan Gum is derived from bacteria viz. Sphingomonas elodea which grows on aquatic plants. Gellan Gum, GELUM, is a multi-functional gelling agent that can impart unique as well as appealing textures to food products & effective at very low percentage. It is of vegetable origin & an alternative to animal-based gelatin. It is Non-GMO, Vegan, gluten-free & allergen-free.

Two types of Gellan Gum GELUM-HA & GELUM-LA are available. GELUM-HA is High Acyl Gellan Gum forms soft, very elastic gels whereas; GELUM-LA is Low Acyl Gellan Gum forms firm, brittle gels. Due to this versatile property, products varying from firm, brittle gels (which easily crumble in mouth) to fluid, elastic gels. Apart from this, Gelan Gum is used as thickener, stabilizer & suspending agent. As it is very quick to set at ambient temperatures, it can allow release of flavor of food.

When is combined with foods rich in calcium, magnesium or potassium is forms gels. To aid setting calcium rich products like dairy products or calcium salts can be used.

Broadly, 4 types of gels can be made by a combination of GELUM-HA & GELUM-LA :

  1. Firm & brittle gels : These can be made by using low concentrations (0.1% & above) of GELUM-LA. These gels are crystal clear & have excellent visual appeal.
  2. Fluid gels : These low viscosity gels can be obtained by stirring solution of GELUM-LA while being cooled. Nevertheless, their astounding suspending effects allows suspending particles of colored spheres, herbs, gases etc.
  3. Elastic gels : Using GELUM-HA more flexible gels can be obtained such that they can be made into thin sheets which can be rolled or folded. 
  4. Gelled Spheres & strands : These can be obtained when pure GELUM solution is added dropwise into aqueous solution of calcium, magnesium, potassium ions etc.
Method of Use:

GELUM is stable to heat & a wide range of pH allowing it to be used in various types of food products. Detailed laboratory experiments should be done to optimize the requisite properties.

Uses
Functions of GELUM

The GELUM is a functional ingredient, exhibiting thickening, gelling, stabilizing, emulsifying, film forming, structuring, fat replacer potential etc. In bakery fillings GELUM provides texture to keep the fillings in place during baking, transportation and consumption.
