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.
Claims19
A powder-form composition comprising 2-acetyl-1-pyrroline incorporated with a support selected from the group consisting of cyclodextrin and maltodextrin.
A product of a process for preparing a flavoring composition comprising:
- hydrolyzing a 2-(1-alkoxyethenyl)-1-pyrroline compound 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 cyclodextrin with the neutralized reaction medium so that a support solution containing up to 20% 2-acetyl-1-pyrroline by weight based on the weight of the cyclodextrin is obtained;
- and
- freeze-drying the support solution to obtain the product.
A product of a process for preparing a flavoring composition comprising:
- 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 with the neutralized reaction medium so that a support solution containing up to 10% 2-acetyl-1-pyrroline by weight based on the weight of the maltodextrin is obtained;
- and
- freeze-drying the support solution to obtain the product in powder-form.
A powder-form composition comprising synthetic 2-acetyl-1-pyrroline incorporated with a support selected from the group consisting of cyclodextrin and maltodextrin.
