L-1-hydroxymethy) alkaneamide derivatives of-L- aspartic acid have been prepared and have been discovered to be non-nutritive sweeteners having favorable chemical and physiological properties for use in compositions ingested orally. The compounds have the general formula
wherein R1 =
R2 = H or CH3; R3 = H or CH3; and R' = CH3, C2H5, i - C3H7 or t-C4H9; except that where R4 is i-C3H or t-C4H9, R2 and R3 are H.
