Abstract
The present invention provides a method for forming caramels having reduced low molecular weight species such as 4-MeI. The low-4-MeI caramels produced by this method have improved stability and taste relative to those known in the art. The invention also extends to the caramels produced by the disclosed methods and the use of such caramels in food and beverages.
Claims14
A method of forming a non-gelling low-4 methyl-imidazole (4-MeI) class IV caramel, comprising (i) providing a solution that comprises a carbohydrate and an acid;
- (ii) initiating a caramelization reaction in the solution;
- (iii) after initiation, adding a portion of ammonium and sulfite to the solution to form a reaction mixture;
- and (iv) continuing the caramelization reaction, thereby producing a non-gelling low-4-MeI class IV caramel, wherein the caramelization reaction in (ii) is initiated by heating the solution to a temperature of at least about 80° C., base is not added during the caramelization reaction and the pH of the reaction mixture is maintained between about 1.2 and about 3.0.
A method of forming a non-gelling low-4-MeI class IV caramel, comprising:
- (i) adding a carbohydrate and an acid to a reaction vessel to provide a first reaction mixture;
- (ii) closing the reaction vessel;
- (iii) adding a first portion of ammonium and sulfite to the first reaction mixture to provide a second reaction mixture;
- (iv) heating the second reaction mixture to a temperature of at least about 80°;
- (v) adding a second portion of ammonium and sulfite to the second reaction mixture to provide a third reaction mixture;
- and (vi) maintaining the temperature of step (iv) or heating the third reaction mixture to a suitable temperature, thereby providing a non-gelling low-4-MeI class IV caramel;
- wherein base is not added after the reaction vessel has been closed and the pH of the second and third reaction mixtures is maintained between about 1.2 and about 3.0.
