It starts with sugar. It tastes like sugar. But it's not sugar.
Splenda /ˈsplɛndə/ is the commercial name and registered trademark of a sucralose-based artificial sweetener owned by the American company Heartland Food Products Group and manufactured by the British company Tate & Lyle. It is available in both granular and dissolvable tablet forms. Sucralose was discovered by Tate & Lyle and researchers at Queen Elizabeth College, University of London, in 1976. Tate & Lyle subsequently developed sucralose-based Splenda products in partnership with Johnson & Johnson subsidiary McNeil Nutritionals, LLC. The Splenda brand was transferred to Heartland Food Products Group after their purchase of the line with investor Centerbridge Partners in 2015.
