Sweetening agents of the formula: ##STR1## wherein R is an heterocyclic group which, in a preferred embodiment, is a 2-cyanopyrid-5-yl or 2-cyanopyrimidin-5-yl group, A is O, NH or NCN, NH being able to be satisfied in hydrochloride form, n is 1 or 2 and B is COOH or a sodium, potassium, ammonium, calcium or magnesium salt.

Pyridinyl compounds of N-carbamoyl-N-thiocarbamoyl- or N-amidino-glycine

Sweetening agents of the general formula: ##STR1## wherein R is a saturated or unsaturated, acyclic, cyclic or mixed hydrocarbon group having 5 to 13 carbon atoms, wherein R' is, in a preferred embodiment, a 4-cyanophenyl or 2-cyanopyrid-5-yl group, and wherein n is equal to 1 or 2.

Sweetening agents derived from N-hydrocarbon-substituted L-aspartic and

Substituted guanidines and ethanamidines are provided as high potency sweetening agents.

Sweetening agents
