摘　　要：传统的高温喷雾干燥法生产微胶囊化类胡萝卜素干粉,虽然干燥速度快,时间短,产品具有良好的分散性和溶解性,生产过程简单和操作控制方便,适用于连续化工业生产,但也存在一定的局限性:产品颗粒细、堆积密度小、复水易抱团、温度高活性成份易发生异构及产品稳定性欠佳等问题突出。而冷凝喷雾干燥技术能成功解决类胡萝卜素产品的这些缺陷,为此研究了冷凝喷雾干燥工艺条件对番茄红素微胶囊化产品的影响,通过单因素分析和正交实验确定了类胡萝卜素冷凝喷雾干燥的最佳工艺条件:乳液黏度500～1000CP,乳液/淀粉流量比1/5,离心头转速900r/min,淀粉送风温度12.5℃,喷雾环孔径0.33mm,乳液温度45～55℃。In the traditional production,high-temperature spray drying was used in microencapsulated carotenoids powder.The drying speed is fast,the product has good dispensability and solubility.The production processing was simple and control was easy.It is good for continuous chemical production,but there are some limitations： the product particles and the packing density are too small;it is easy to aggregate;high temperature also trigger the isoformat of the product and product stability was poor.The freezing spray technology can successfully solved those defects.It was applied on the lycopene microencapsulated products,the impact of a single factor analysis and orthogonal experiment was used to optimize the condition.The results were： emulsion viscosity of 500~1000CP,latex / starch flow 1 / 5,the heart speed 900r/min,starch air inlet temperature 12.5 ℃,spray ring diameter 0.33mm,emulsion temperature 45 ~ 55 ℃.
