In Australia, it is approved for use in the Australian market by the government.

Food and Agriculture Organization

Independent research done By FAO concluded that the cassia gum is stable agent of any chemical modifications for a minimum of 20 months. Any changes detected are within the limits of specification. The gum is hygroscopic until a moisture level of 8 – 12% is achieved. The cassia powder, when used at the recommended levels and it does not interact with the nutrients. There are also no degradation products from cassia gum in the foodstuffs.


The cassia gum powder is a natural polysaccharide that is a good thickener and stabilizer used in the food & pet food processing industry. It has been recognized as a safe product globally after intensive research, and has been classified as “Generally recognized as safe” in food when used according to the stipulated levels. The product has also been approved for use in most countries through official registration, such as in the European Union, USA, china, Japan and many more nations around the world.
