Cassia gum is manufactured from the endosperm of Senna obtusifolia or Cassia obtusifolia or Cassia Tora or Cassia Occidentalis). It is mainly used as a thickener and gelling agent in foods and pet foods and grows mainly in subtropical regions and is grows mostly wild and occasionally cultivated.
Cassia Gum is comprised of at least 75% polysaccharide consisting primarily of a linear backbone chain of mannose with side galactose units The ratio of Mannose : Galactose is about 5: 1.
Cassia gum, like LBG can form gels with other colloids like Carrageenan and Xanthan and is therefore used in the manufacture of gels in the food and pet food applications in combination of other colloids.

Splitting the Cassia Tora Seeds
The seed consists of an outer husk, an endosperm (cassia tora split) and the ovary or germ. Only the endosperm or split, which contains mainly polysaccharides, is used for the production of the cassia gum.
Both husk and germ are removed in the de-husking and splitting process. The impact of the splitting procedure is that both husk and germ are loosened from the endosperm and made brittle by heating and can be removed in the subsequent purification procedure after pulverization. The split (endosperm), however, remains intact at these temperatures. Due to its much greater particle size, the split can be separated from husk and germ particles through a couple of physical cleaning steps.
The splitting procedure starts with roasting of the seeds. All seeds are heated for several minutes. During the roasting process the endosperm (split) remains intact and flexible, while husk and germ, which are more sensitive to heat, become brittle. Mechanical stress pulverizes husk and germ and the powder is separated from the intact split by sieving. Remaining traces of husk and germ on the split particles are finally removed through a series of physical cleaning steps.
Method of Manufacturing cassia gum powder
The seeds are dehusked and de-germed by milling and screening of the endosperm.
It is high molecular weight (approximately 200,000 – 300,000) polysaccharides composed of galactomannans; the mannose:galactose ratio is about 5:1. Semi-refined Cassia gum normally containing detectable amounts of anthraquinones.
The raw material seed is subject to different mechanical cleaning steps in order to remove other impurities, such as, farm waste, undeveloped seeds and stones.
After cleaning raw material is subject to a de-husking and splitting process.
Thermal and mechanical treatment removing husk and germ from the seeds resulting in splits. Finally the splits are ground to a uniform small particle size powder.
Method of Manufacturing cassia gum powder
- It is hot water soluble and requires heating to fully solubilise and reach full viscosity in aqueous solutions.
- It is comprised of at least 75 % polysaccharide consisting primarily of a linear chain of 1,4-β-D-mannopyranose units with 1,6 linked α-D-alactopyranose units.
- The ratio of mannose to galactose is about 5:1.
- It forms firm thermoplastic gels with carrageenan.
- Cassia gum and xanthan gum, on their own, do not have the ability to form gels. But cassia gum combined with xanthan gum, aqueous dispersions of cassia gum form cohesive, elastic gels.
- It is known as one of the best gelling agent, thickening additives, emulsifying additives and stabilizing additives.

Gelling properties of refined cassia gum powder
Refined Cassia gum is a high number of galactose side chains prohibit the synergistic gelling effect with anionic polymers. As a result, a smaller amount of hydrocolloid blend containing cassia gum is needed in a food product to achieve the same effect as with carrageenan alone or blends of carrageenan with other related galactomannans.
Cassia Gum is mainly used as a
- Gelling Agent
- Bonding agent
