What Is Cassia gum?
Cassia gum is a galactomannan polysaccharide extracted from the endosperm of Senna obtusifolia seeds (cassia). It has a galactose-to-mannose ratio of approximately 1:5, giving it good cold-water gelation ability in combination with xanthan gum or carrageenan. Used as a thickener and gelling agent in processed meats, dairy products, and pet food. EFSA authorized cassia gum for food use in 2012, establishing an ADI of 30 mg/kg body weight after evaluating genotoxicity and reproductive toxicity studies. It is approved in the EU and several other jurisdictions.
? Did You Know?
Cassia gum occurs naturally in Cassia tora seeds and Cassia occidentalis seeds. Many people consume it daily without realizing it's also a listed food additive.
Cassia gum is derived from plant materials — its origin is more natural than its E-number might suggest.
Beyond food, Cassia gum is also used in cosmetics, household products. Its versatility makes it one of the most multi-purpose chemical compounds in everyday life.

Natural Occurrence
A galactomannan polysaccharide extracted from the endosperm of cassia seeds. The cassia plant is native to tropical regions of Asia and the Americas, and its seeds have been used in traditional Chinese medicine.
Manufacturing
Seeds of Cassia tora or Cassia occidentalis plants are dehulled to remove the outer coat. The endosperm is separated, ground, and extracted to produce cassia gum powder. The polysaccharide is then purified and standardized.
Applications Beyond Food
Used occasionally in cosmetic formulations as a thickener.
Primarily used in pet food industry
