Cassia gum

Cassia gum is a galactomannan polysaccharide extracted from the endosperm of Senna obtusifolia (cassia) seeds. It is structurally related to locust bean gum (E410) and functions as a thickener and gelling agent in food products. Its primary food application is in canned pet food, where it is used to create firm gel matrices, but it is also permitted in certain human food applications in the EU.

JECFA's ADI is "not specified," evaluated in 2004. Cassia gum is a non-digestible fibre that passes through the gastrointestinal tract without significant absorption. It provides prebiotic benefits through fermentation in the colon. The leaves and unprocessed seeds of cassia plants contain anthraquinones with laxative activity, but food-grade cassia gum endosperm extract is free from these compounds at permitted use levels.

Cassia gum is approved in the EU with restricted use in certain human food categories and in pet food. Its use in human food is less widespread than locust bean gum or guar gum. For the general population there are no safety concerns with food-grade cassia gum. Its clean label as a natural gum exudate makes it appropriate for products positioning themselves on natural ingredients.
