Sucralose was discovered in 1976 by scientists from Tate & Lyle, working with researchers Leslie Hough and Shashikant Phadnis at Queen Elizabeth College (now part of King's College London). While researching ways to use sucrose and its synthetic derivatives for industrial use, Phadnis was told to "test" a chlorinated sugar compound. Phadnis thought Hough asked him to "taste" it, so he did. He found the compound to be exceptionally sweet.
