Dihydrochalcones of the formula ##STR1## are disclosed wherein M.sup.+ is a cation, X is H or OH, and R is a lower alkyl. These materials are useful as sweeteners for edibles. They may be prepared by electrophilic addition of the 3-sulfo-5,6-dihydroxyhexyl group to the corresponding flavanones, using epoxysultone, and thereafter converting to the dihydrochalcone.
