E427: Cassia Gum
Main role: gelling and stabilization
Also listed as: cassia seed gum
What is E427 (Cassia Gum)?
Cassia gum is a galactomannan preparation obtained from specified cassia seed sources. It is commonly useful in combinations with other hydrocolloids rather than as a universal stand-alone gelling powder. Its defined food-grade purity is important.
What does it do in food?
Its main role is gelling and stabilization. Texture ingredients help a recipe control thickness, binding, or separation. Their behavior depends on temperature, acidity, concentration, and other ingredients; two thickeners with similar names may not perform identically.
Food and formulation examples
- Specified dessert gels
- Texture-control blends
- Selected processed-food formulations
These examples describe formulation roles, not a list of unrestricted legal uses. Availability and permitted applications differ by country and food category.
Label names and ingredient questions
Look for E427, E 427, or the ingredient name. Related names and label terms include cassia seed gum. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Cassia gum is not the same as cassia cinnamon or an herbal cassia preparation. The plant-related name refers to a specified seed gum with its own identity and use conditions.
Is E427 safe?
There is no meaningful personal risk estimate from an E number alone. Food-grade specifications, allowed uses, amount consumed, and individual circumstances all matter. The authorization record below gives the legal scope; it is not a claim that every possible use is appropriate.
A label identifies the ingredient but usually not its concentration. Calculating daily intake requires the amount in the food and the quantities eaten.
Authorization and conditions of use
The Great Britain food additive register lists E427 as Cassia gum. This is an entry subject to its stated conditions, not unrestricted permission for every food. The record links to the applicable authorization terms. For an EU product, use the European Commission food additive database to check the relevant food category and limits. Other countries may use different names or rules.
