摘要: 探讨甘薯叶提取物的喷雾干燥制备工艺。在单因素试验基础上,通过L9(34)正交试验对喷雾干燥工艺进行优化,确定最佳的喷雾干燥条件为进风温度190℃、进料流量300mL/h、总固形物含量25%,其中进料流量对喷雾干燥效果的影响最大。在此条件下所得产品出粉率为53.78%、含水量5.29%、活性损失率11.13%。

Abstract: In order to explore spray drying conditions of sweet potato leave extract (SPLE), orthogonal tests were used to optimize the spray drying conditions of SPLE on the basis of single factor tests. The results indicated that the optimal spray drying conditions were inlet air temperature of 190 ℃, flux rate of 300 mL/h and total solid content of 25%. Under the optimal spray drying conditions, the yield of the product, water content and activity loss rate were 53.78%, 5.29% and 11.13%, respectively.
