ABSTRACT:
Ammonia caramel color is formed in a fast cook method under elevated pressure and temperature by reacting ammonia catalyst with a carbohydrate syrup wherein the amount of water in the ammonia carbohydrate syrup mixture is controlled. The water content is maintained at preferably less than 40% of the mixture during a substantial portion of the caramelization reaction. Preferably the ammonia caramel is formed by reacting a carbohydrate syrup having a solids content of at least 75-80% with an anhydrous ammonia catalyst and reacting this at elevated temperature and super-atmospheric pressure over a period of 1-2 hours. Although the caramelization reaction generates water, the water content will not exceed 40%. This facilitates the rapid formation of caramel color without increasing the 4MeI or THI content, and without hazing of the caramel color. Further this produces a remarkably salt stable product.
