What Is Aspartame-acesulfame salt?
The aspartame-acesulfame salt (E962) is a compound formed from aspartame and acesulfame potassium that dissociates in solution to release both sweeteners. It provides the synergistic sweetness of the aspartame-acesulfame combination in a single ingredient form. It inherits the properties of both components: the synergistic sweetness profile and the PKU labeling requirement from aspartame. JECFA established an ADI of 0–40 mg aspartame-acesulfame salt/kg body weight. Approved in EU and other jurisdictions for use in the same applications as its component sweeteners.
? Did You Know?
Aspartame-acesulfame salt isn't just a food additive — it's also used in medicine.
Aspartame-acesulfame salt is fully synthetic — it doesn't exist in nature and is manufactured entirely through chemical processes.
Regulatory Analysis
The aspartame-acesulfame salt (E962) is distinctive in that it is regulated as a separate food additive entity but assessed for safety by reference to its two component sweeteners, aspartame (E951) and acesulfame-K (E950), rather than as a novel compound. EFSA's 2016 re-evaluation confirmed that the ADIs for the individual components govern the safety assessment for E962, and no separate ADI for the combined salt was deemed necessary. This approach carries an important implication: the 2023 IARC/WHO reassessment classifying aspartame as 'possibly carcinogenic to humans' (Group 2B) and the subsequent scrutiny of aspartame's ADI directly affects E962 as well, since consumption of E962 must be counted against the aspartame ADI of 40 mg/kg body weight per day. Similarly, EFSA's 2025 reduction of the acesulfame-K ADI to 9 mg/kg applies to the acesulfame-K released from E962. The additive thus inherits all regulatory updates affecting either component.

Everyday Perspective
For a 60kg adult, this limit is roughly equivalent to consuming:
Natural Occurrence
This additive is not known to occur naturally in significant quantities.
Manufacturing
Formed by combining aspartame and acesulfame potassium in aqueous solution to create a stable molecular salt. The combination exhibits better stability than aspartame alone.
Applications Beyond Food
Sweetener in chewable tablets and syrups
