焦糖色素的色率和红色素指数是衡量焦糖色素品质的2个重要指标，但这2个指标是相互制约的。本文以精炼糖糖蜜为原料，利用氨法制备焦糖色素。通过单因素实验研究，确定影响焦糖色素色率和红色素指数的主要因素为反应温度、反应时间和催化剂的量，然后以此设计正交实验，确定制备高色率焦糖色素的工艺为反应温度120～125℃，反应时间1.5 h，铵盐添加量为10%（以NH4+的质量与糖蜜干固物质量计算）；制备高红色素指数焦糖色素的工艺为反应温度110～115℃，反应时间0.5 h，铵盐添加量3%（以NH4+的质量与糖蜜干固物质量计算）。

Color rate and red index are the two important quality indicators of caramel pigment, but the two indicators are mutually restricted. This paper prepared caramel pigment by ammonia method using refined sugar molasses as raw materials. Main factors that affect the color ratio and red index of caramel pigment were determined as reaction temperature, reaction time and catalyst dosage, through the single factor experiments. The orthogonal experiment results show that the preparation conditions for caramel pigment with high color ratio are as follows:the reaction temperature of 120~125℃, reaction time 1.5 h, ammonium salt content 10%. Preparation conditions for high red index caramel pigment are:reaction temperature of 110~115℃, reaction time 0.5 h, ammonium addition 3%.
