Ergänzende Hinweise
DefinitionA sugar-based food colorant made from liquid corn syrup by heating in the presence of catalysts to approximately 250F (121C) for several hours, cooling to 200F (93C), and filtering. The brown color results from either Maillard reactions, true caramelization, or oxidative reactions. Caramels are colloidal in nature, the particles being held in solution by either positive or negative electric charges.
