Origin

Cassia gum is a polysaccharide derived from the endosperm of the seeds of Cassia tora and Cassia obtusifolia plants, which belong to the legume family. These plants are native to India and other tropical regions of Asia. The gum is extracted from the seeds through a process involving milling, sieving, and purification. The resulting powder is then processed to achieve the desired properties for use as a food additive.

Usage

Cassia gum is primarily used as a thickener, emulsifier, and stabilizer in various food applications. It is often found in pet foods, where it provides texture and helps to bind ingredients. In human food, its applications are more limited due to regulatory restrictions. However, it can be used in certain processed foods, such as sauces, dressings, and bakery products, where it contributes to viscosity and stability. It is also used in air freshener gels. The European Food Safety Authority (EFSA) has evaluated cassia gum for use in food.

Side Effects

While cassia gum is generally considered safe for its approved uses, high levels of consumption may lead to gastrointestinal issues such as bloating, gas, and diarrhea. Some studies have raised concerns about potential liver toxicity at very high doses, but these findings are not conclusive at levels typically consumed in food. Regulatory bodies like EFSA have set specifications and usage limits to ensure consumer safety. It is important to note that the safety assessments are based on the intended uses and levels of cassia gum in food products.

Regulatory Status

Cassia gum is approved as a food additive in the European Union (E427) under specific conditions. The European Commission has established specifications for cassia gum, including limits on heavy metals and other contaminants. The use of cassia gum in food is subject to these regulations. The EFSA has conducted several evaluations of cassia gum and has established an Acceptable Daily Intake (ADI) of 'not specified', meaning that no adverse health effects are expected at the levels of intake necessary to achieve the desired technological effect. However, its use is restricted in certain food categories. In the United States, cassia gum is permitted for use in animal feed but has limited approval for use in human food. The FDA regulates its use to ensure safety and compliance with food additive regulations.
