Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of acacia gum (gum Arabic) as a technological additive for all animal species. The FEEDAP Panel concluded that acacia gum does not raise concerns for genotoxicity and is considered safe for all animal species, at levels ranging 278–4889 mg/kg complete feed. Regarding the user safety, the additive was considered a potential dermal and respiratory sensitiser, and any exposure by dermal or inhalation routes is considered a risk. The Panel concluded that the additive is efficacious as an emulsifier and in stabilising emulsions over time, which would support its efficacy as a stabiliser.
