| titleOfInvention | Isolating caramel colouring compounds |
| abstract | Essential colouring compounds are isolated from caramelised syrups having a tinctorial power of 18 to 40 by mixing the syrup with an alcohol mixture comprising 3 to 5 parts by volume of a water miscible alcohol having 1 or 2 carbon atoms to one part by volume of a monohydric alcohol having 2 to 6 carbon atoms said mixture containing 5 to 32 per cent by volume of water, permitting the mix to separate into two layers and separating the solid material from the lower layer. The caramelized sugar solution, from which the colouring is to be precipitated, should be cooled to 80 DEG F. and preferably to less than 50 DEG F. and its pH should be between 2.5 and 3.5. Preferably the caramel solution is added to the alcohol solution. A number of examples is given. Specification 685,961 is referred to. |
