Chemical structure of Aspartame-acesulfame salt, from PubChem compound 25130065
Structure from PubChem CID 25130065 (National Library of Medicine, public domain). A depiction of one compound: where a listing covers a family, or a substance has no single structure, this page shows none.

Aspartame-acesulfame salt is a single salt formed from aspartame and acesulfame rather than a physical blend of the two. The pairing is used because each sweetener masks the other's aftertaste, and the salt delivers a fixed ratio.

How much is permitted

A listing usually limits the quantity as well as the food. Only one of the forms that takes is a figure: quantum satis and good manufacturing practice permit the amount the technological effect requires and no more, which is a limit rather than the absence of one. Figures below are the range across every food category this page is listed in, and categories differ between regulators — see how much is permitted.

What a label must say

Words a food containing Aspartame-acesulfame salt is obliged to carry, quoted from the instrument that imposes them. A required statement is a fact about the regulation, not a finding about the substance — every rule below applies where the additive is authorised.

Every rule collected at what a label must say.

What it is made from

Crystallised from a solution of aspartame and acesulfame potassium, producing a compound of roughly two parts aspartame to one part acesulfame. It carries the same phenylalanine declaration as aspartame, because it releases it in digestion.

How the EU defines it

The legal specification an additive must meet to be sold as this E number in the EU — what it is, how it may be made, and the purity it must reach. From Commission Regulation (EU) No 231/2012.

E 962 Salt of aspartame-acesulfame

The salt is prepared by heating an approximately 2:1 ratio (w/w) of aspartame and acesulfame K in solution at acidic pH and allowing crystallisation to occur. The potassium and moisture are eliminated. The product is more stable than aspartame alone.

The salt is prepared by heating an approximately 2:1 ratio (w:w) of aspartame and acesulfame K in solution at acidic pH and allowing crystallization to occur. The potassium and moisture are eliminated. The product is more stable than aspartame alone.

Principle Aspartame-acesulfame salt is dissolved in methanol and potentiometrically titrated with tetrabutylammonium hydroxide. Apparatus Use a suitable autotitrator (e.g., Metrohm 670, or equivalent) equipped with a glass pH electrode and a silver-silver chloride double liquid junction reference electrode (e.g., Yokogawa pH electrode SM 21-AL4 or equivalent and reference electrode SR 20-AS52 or equivalent). Standard tetrabutylammonium hydroxide solution Prepare a 0.1 M solution in a 1:1 (v:v) mixture of 2-propanol:methanol. Weigh 24 and 98 mg benzoic acid with 0.01 mg accuracy and dissolve each into two 50-ml volumetric flasks and dilute to volume with 2-propanol. Titrate both solutions with the 0.1 M tetrabutylammonium hydroxide and record the volume required to reach the equivalence point with 0.001 ml accuracy. Perform a blank titration on 50 ml of 2-propanol. Determine the standard factor (F) for each titration. and average the two factors as follows: F = [(W S x 1000)/(122 x (V S -V O ))] Where: W S = weight of primary benzoic acid (g) V S = volume of equivalence point (ml) V o = volume of equivalence for the blank (ml) 122 = molecular weight of benzoic acid Procedure Weigh accurately 100 to 150 mg of sample and dissolve it in 50-ml methanol. Titrate with the standardized 0.1 M tetrabutylammonium hydroxide. Determine the volume (ml) of the standard solution needed to reach the first (V1) and second (V2) equivalency points. Perform a blank titration on the methanol. Calculate the acesulfame and aspartame content as follows: Acesulfame content (% m/m) = [(V 1 -V B ) x N x 163/(10 x W)] Aspartame content (% m/m) = [(V 2 -V 1 ) x N x 294/(10 x W)] Where: W = Weight of sample (g) V 1 = volume of first equivalence point (ml) V 2 = volume of second equivalence point (ml) V B = volume of equivalence point of blank (m)l N = normality of the standard 0.1 M tetrabutylammonium hydroxide 163 and 294 = formula weights of acesulfame and aspartame moieties, respectively 10 = conversion of g to % (m/m)

5-Benzyl-3,6-dioxo- 2- piperazine acetic acid
Principle 5-benzyl-3,6-dioxo- 2-piperazine acetic acid is determined in aspartame-acesulfame salt dissolved in methanol-water by comparison to an authentic standard after separation by HPLC. Apparatus Use a suitable high-pressure liquid chromatograph equipped with UV detector for measuring absorbance at 210 nm and a 250 x 4.6 mm column packed with octyldecyl silanized silica (10- μ m Partisil ODS-3 or equivalent) and operated under isocratic conditions at 40 ° . Mobile phase Dissolve 5.6 g of potassium phosphate monobasic into 820 ml of water in a 1-l flask and adjust the pH to 4.3 with phosphoric acid. Add 180 ml of methanol and mix. Filter through a 0.45 μ m filter and de-gas. Standard Accurately weigh approximately 25 mg of authentic 5-benzyl-3,6-dioxo-2-piperazine acetic acid into a 100-ml volumetric flask; add 10 ml of methanol to dissolve the material and dilute to volume with water and mix. Accurately transfer 15 ml of this solution to a 50-ml flask and dilute to volume with a 1:9 (v:v) mixture of methanol:water prepared on the day of use. Sample Accurately weigh approximately 50 mg of sample into a 10 ml volumetric flask and dilute to volume with a 1:9 (v:v) mixture of methanol:water prepared on the day of use. Procedure Separately inject 20 μ l portions of the standard and the sample into the chromatograph (The flow rate of the mobile phase is about 2 ml/min.) and record the peak areas in standard and sample chromatograms (under the conditions described, the retention time of 5-benzyl-3,6-dioxo-2-piperazine acetic acid and aspartame are approximately 4 and 11 min, respectively). Measure the peak area response of 5-benzyl-3,6-dioxo- 2-piperazine acetic acid in each chromatogram and calculate the percentage of 5-benzyl-3,6-dioxo-2-piperazine acetic acid as follows: % = 1000(A U C S )/(A S W u ) Where A U and A S are the peak areas of 5-benzyl-3,6-dioxo-2-piperazine acetic acid in the sample and standard, respectively, C S is the concentration of 5-benzyl-3,6-dioxo-2-piperazine acetic acid in the standard in mg/ml and W u is the weight, in mg, of aspartame-acesulfame salt taken in the sample preparation.

Evidence and how bodies read it

What assessing bodies concluded

Each conclusion is paraphrased in the body's own framing, from the published opinion linked beneath it. Where bodies differ, both stand; this site does not adjudicate between them or add a view of its own.

  1. EFSA 2026

    Assessing the salt of aspartame-acesulfame (E 962) through its components, the FAF Panel relied on the 2025 acesulfame K ADI of 15 mg/kg bw/day and, after updating its assessment of aspartame, confirmed the aspartame ADI of 40 mg/kg bw/day. Exposure did not exceed either ADI, and it concluded there is no safety concern at reported uses for E 950, E 951 and E 962.

Common questions

Assembled from what is above, in the words the questions are usually asked in. Each answer is the same statement the relevant section makes, with the same citations behind it.

What is E 962?
E 962 is Aspartame-acesulfame salt. Aspartame-acesulfame salt is a single salt formed from aspartame and acesulfame rather than a physical blend of the two. The pairing is used because each sweetener masks the other's aftertaste, and the salt delivers a fixed ratio.
What is Aspartame-acesulfame salt used for in food?
It is listed as a sweetener — the role Codex and the EU assign it. This page shows every function each regulator records, with the citation for each.
Where is Aspartame-acesulfame salt permitted?
Of the seven regulators this site reads, Australia and New Zealand, the EU, Great Britain and the Codex standard permit it. Each permission is for named foods at named levels, not a blanket one; the table on this page gives them with citations.
Is Aspartame-acesulfame salt vegan?
Yes. Aspartame-acesulfame salt is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
