Abstract
The present invention relates to a process for producing a formulation for aromatizing a product, in particular a food product, a semi-luxury food product, cosmetic or pharmaceutical product, and dietary supplement, which preferably comprises at least one (alkyl) pyrazine according to formula (Ia), and/or at least one (alkyl) pyrazine according to formula (Ib) wherein R1, R2, and R3 represent the groups defined in the claims.
Claims22
1-26. (canceled)
A process for producing a formulation which comprises at least one (alkyl) pyrazine, comprising the steps of:
- (a) providing at least one compound according to formula (II) or (III) or (IIIa)
- wherein
- R2 and R3 are identical or different and independently of one another represent hydrogen or C1-4 alkyl;
- or
- R2 and R3 are bonded to one another and together form a group of the formula
- wherein
- A, B, C, and D independently of one another represent hydrogen or C1-4 alkyl,
- (b) providing an alpha-amino acid,
- (c) bringing into contact the at least one compound according to formula (II) or formula (III) or formula (IIIa) and the alpha-amino acid;
- wherein at least one solvent suitable for the production of food products and having a boiling point of at least 140° C. is used;
- and wherein the solvent is added prior to step (c) and/or in step (c), wherein the compound according to formula (II) or (III) or (IIIa) is selected from the group consisting of:
35-38. (canceled)
A process for producing a formulation which comprises at least one (alkyl) pyrazine, comprising the steps of:
- (a) providing at least one compound according to formula (II) or (III) or (IIIa)
- wherein
- R2 and R3 are identical or different and independently of one another represent hydrogen or C1-4 alkyl;
- or
- R2 and R3 are bonded to one another and together form a group of the formula
- wherein
- A, B, C, and D independently of one another represent hydrogen or C1-4 alkyl,
- (b) providing an alpha-amino acid,
- (c) bringing into contact the at least one compound according to formula (II) or formula (III) or formula (IIIa) and the alpha-amino acid;
- wherein at least one solvent comprising at least one hydroxy group is added prior to step (c) and/or in step (c), wherein the compound according to formula (II) or (III) or (IIIa) is selected from the group consisting of:
A method of increasing yield in a process for producing an (alkyl) pyrazine comprising the step of carrying out a reaction for producing the (alkyl) pyrazine in a solvent comprising at least one hydroxy group,
- wherein the solvent comprising at least one hydroxy group is part of a solvent mixture comprising triacetin.
A method for regulating molar ratios of (alkyl) pyrazines in a process for producing (alkyl) pyrazines, comprising carrying out said process in a solvent comprising at least one hydroxy group,
- wherein the (alkyl) pyrazines have the structures of formula (Ia) and formula (Ib),
- wherein
- R1 represents hydrogen or methyl,
- R2 and R3 are identical or different and independently of one another represent hydrogen or C1-4 alkyl;
- or
- R2 and R3 are bonded to one another and together form a group of the formula
- wherein A, B, C, and D independently of one another represent hydrogen or C1-4 alkyl, and
- wherein the solvent comprising at least one hydroxy group is part of a solvent mixture comprising triacetin.
