β-胡萝卜素微胶囊化工艺参数的研究

Study on the microencapsulation technology of β-carotene

研究喷雾干燥微胶囊化工艺参数 ,结果表明 ,最佳工艺参数为 :乳化温度 70℃ ,均质压力 4 0Mpa ,喷雾干燥进风温度 195℃、出风温度 85± 5℃ ,进料固形浓度为 2 0 %。

The optimal microencapsulation technology was obtained:the pressure and temperature of emulsion homogenization were 40Mpa and 70℃ respectively for the spray drying, the inlet concentration of emulsion was 20% (W/V);XG concentration was 0.5% (W/V);inlet air temperature was 195℃,control outlet air temperature at (85±5℃).
