Abstract
Volatile flavour molecules having a particular cyclic enolone structure are stabilised by complexation with alkaline earth metal ions. These complexes are stable until exposed to certain conditions of temperature and/or moisture.
Claims21
A stable flavour complex, comprising an alkaline earth metal ion and two cyclic molecules, wherein for each of said molecules the cyclic ring thereof comprises first and second functional groups, which functional groups are located at adjacent positions of the cyclic ring each of which functional groups provides a bond with said ion, said cyclic ring further comprises a double bond in a conjugated relationship with said second functional group, and one at least of said cyclic molecules being a flavour molecule, said flavour molecule being released upon exposure of said flavour complex to moisture and/or heat.
A method of stabilising volatile flavour compounds, wherein an alkaline earth metal ion and two volatile cyclic molecules, are reacted together in solution, at least one of said cyclic molecules being a flavour molecule, a stable flavour complex being extracted from the reaction mixture by means of a separation technique, said cyclic molecules comprising first and second functional groups, which functional groups are located at adjacent positions of the cyclic ring, and said ring of each cyclic molecule further comprising a double bond in a conjugated relationship with said second functional group and said flavour molecule being released upon exposure of said flavour complex to moisture and/or heat.
