basic reacting amino acids which compounds are surprisingly no longer bitter but have a pure sweet taste the use of these amino acids in particular arginine in preparations for oral administration is thus considerably simplified preparation of these saltlike compounds is simple for example one equivalent of l arginine 1 is reacted in water with one equivalent of acesulfame h 2 l arginine acting as base and acesulfame h as acid acesulfame h is the corresponding acid to the commercially available acesulfame k for example sunett u00ae nutrinova frankfurt a m germany which can be converted to acesulfame h by protonation by a strong acid for example sulfuric acid acesulfame h and acesulfame k can also be synthesized by methods known from the literature cf ep a 0 155 643 the resulting salt adduct 3 is in addition considerably more water soluble than the non protonated free l arginine 1 from the resultant reaction solution the reaction product is produced in a simple manner by removing the water for example by evaporation under reduced pressure the l arginine acesulfame salt 3 is according to 1 h nmr a 1 1 adduct if two equivalents of acesulfame h 2 are used as acid there results an also stoichiometric 1 2 adduct of an l arginine acesulfame salt 4 whose structure has been confirmed by.
