Ammonia caramel coloring is formed continuously by pumping a heated stream of corn syrup through a reaction zone under pressure. 4MeI content and THI content are maintained at a low level by preheating the ammonia catalyst prior to injection into the reaction zone. Preferably ammonia catalyst is added to the reaction zone at a plurality of injection ports. This permits rapid formation of ammonia caramel coloring without increasing the 4MeI of THI content, and without hazing of the caramel color. |
