Manufacturing method of caramel coloring with reduced content of 4-methylimidazole

摘要

The present invention relates to a method for manufacturing a caramel coloring comprising: a step for preparing a reactor accommodating one or more water soluble carbohydrate liquids selected among liquid saccharides, starch hydrolysate liquid, or molasses in a part of the interior space thereof; a step for supplying an ammonium compound into the reactor through the upper part of a reactor not accommodating the water soluble carbohydrate liquids; and a step for heat treating the water soluble carbohydrate liquids in the reactor under the presence of the ammonium compound. A caramel coloring with markedly reduced content of 4-methylimidazole is obtained when manufacturing the caramel coloring using the method according to the present invention. Also, the caramel coloring manufactured by the method according to the present invention maintains the optimum level of chromaticity, thereby being applicable to various foods including coke, fermented black bean paste products, a sauce for glazed pigs feet, and confections.
