DHA微胶囊配方乳粉的喷雾干燥工艺优化研究

Optimization of the spray drying method in the application of DHA in formula milk powder

  • 摘要: 采用单因素实验,研究了均质压力、进料流量、进风温度对二十二碳六烯酸(DHA)微胶囊配方乳粉品质的影响,并进一步对工艺参数进行响应面优化。结果表明:均质压力、进料流量、进风温度对DHA保留率均有极显著影响(p<0.01);响应面优化得到DHA微胶囊在配方乳粉中应用的最佳工艺条件为:均质压力36~37MPa、进料流量20.50mL/min、进风温度165℃,DHA保留率可达95.28%±0.54%。 

     

    Abstract: The effects of homogenization pressure, feed flow rate and inlet air temperature on the application of Docosahexaenoic Acid (DHA) in formula milk powder were studied by single factor experiment, then the process conditions of the application were optimized by response surface method (RSM) .The results showed that the effects of homogenization pressure, feed flow rate and inlet air temperature on the retention rate of DHA were significant (p<0.01) .By the RSM transactional analysis, the optimum process conditions were optimized as following:homogenization pressure 36 ~ 37MPa, feed flow rate 20.50mL/min, inlet air temperature 165℃, respectively.The retention rate of DHA was up to 95.28%±0.54% under the optimum condition.
