The present invention relates to a novel sweetening agent and to its method of preparation. This novel sweetening agent is a 2-substituted acyl derivative of L-aspartic or L-glutamic acid and has the general formula ##STR1## R being an acyl group of the formula ##STR2## and R' being a group of the formula ##STR3## R.sub.1, R.sub.2, R.sub.3, X, Y and Z being variously defined. This novel sweetening agent is essentially characterized by a high sweetening potency and a high stability compatible with the conditions of industrial use, and is applied especially for sweetening soft drinks.
