Aspartame-acesulfame salt

Aspartame-acesulfame salt is an artificial sweetener marketed under the name Twinsweet. It is produced by soaking a 2:1 mixture of aspartame and acesulfame potassium in an acidic solution and allowing it to crystallize; moisture and potassium are removed during this process. It is approximately 350 times as sweet as sucrose. It has been given the E number E962.

History
Aspartame-acesulfame salt was invented in 1995 by sweetener expert Dr John Fry while working for The Holland Sweetener Company (HSC), a subsidiary of DSM. HSC marketed it with the name Twinsweet. It was approved for use as an artificial sweetener in the European Parliament and Council Directive 94/35 EC as amended by Directive 2003/115/EC in 2003. In North America, it falls under the same regulations as aspartame and acesulfame-K. It is also approved for use in China, Russia, Hong Kong, Australia, and New Zealand.

In December 2006, HSC ceased all of its aspartame operations, citing a glut in the market driving prices below profitable values. The rights to aspartame-acesulfame are now owned by The NutraSweet Company Inc., who has continued to market the sweetener successfully in the United States and European Union.
