ABSTRACT:
A powder-form composition of 2-acetyl-1-pyrroline incorporated with a support of maltodextrin and/or cyclodextrin. The composition is prepared by hydrolyzing a 2-(1-alkoxyethenyl)-1-pyrroline with an acid to obtain a reaction medium, adding an equimolar amount of a base to the reaction medium to obtain a neutralized reaction medium containing 2-acetyl-1-pyrroline, combining maltodextrin and/or cyclodextrin with the neutralized reaction medium to obtain a support solution and freeze-drying the support solution to obtain the composition.
