Abstract

The invention discloses a production technology capable of reducing the content of 4-methylimidazole in caramel color produced by an ammonia process. The production technology comprises the following steps of (1) acquiring concentrated starch sugar; (2) preparing a catalyst: enabling an ammonia compound to be prepared into an ammonia solution and enabling an ammonium compound to be prepared into an ammonium solution, wherein the catalyst at least comprises one kind of the ammonia solution and the ammonium solution; (3) performing a heating reaction: directly leading steam to a reaction kettle for heating, wherein the steam is in direct contact with the starch sugar for heating, when the starch sugar is raised and kept at 100-115 DEG C, continuously adding the catalyst prepared in the step (2) to the reaction kettle, continuously and directly leading the steam, keeping the temperature of 100-115 DEG C, when a color rate meets requirements, stopping the reaction, and enabling the heating reaction to be always performed at ordinary pressure; and (4) performing cooling and performing filtering so as to obtain the caramel color. According to the production technology disclosed by the invention, the problems that the content of the 4-methylimidazole in the caramel color produced by a conventional ammonia process is high is solved.

Description

technical field [0001] The invention relates to the technical field of caramel color production, in particular to a production process for reducing the content of 4-methylimidazole in ammonia-based caramel color. Background technique [0002] Caramel color has a wide tradition of use in our country, and it is the most used food coloring. According to the different production processes, it can be divided into four categories: ordinary method caramel color, caustic sulfite method caramel color, ammonia method caramel color and ammonium sulfite method caramel color. Ammonia caramel color is positively charged. It is the only positively charged caramel color among the four categories. It can be stably present in beer, soy sauce, and vinegar products, and it plays an extremely important role in the food field. [0003] The Maillard reaction mainly occurs in the production process of ammonia caramel color, that is, ammonia and (or) ammonium compound and carbonyl compound undergo ...
