摘要
以新鲜山药为主要原料,探究不同助干剂的添加量对喷雾干燥山药粉集粉率和水分含量的影响。采用单因素试验分别考察麦芽糊精、β-环糊精和阿拉伯胶的添加量对山药喷雾干燥效果的影响。在此基础上,利用正交试验确定最佳的工艺条件。结果显示,麦芽糊精、β-环糊精和阿拉伯胶添加量分别为50%、10%和1.0%时对山药的喷雾干燥效果最好,山药粉集粉率高达36.25%,水分含量为5.49%。
With fresh Chinese yam as the main raw material,the effects of the amount of drying aids added on the yield and moisture content of spray-dried Chinese yam powder were investigated. Single-factor experiment was employed to explore the effects of maltodextrin,β-cyclodextrin,and gum arabic on the spray drying of Chinese yam,respectively. On this basis,orthogonal test was used to determine the optimal technological conditions.The results showed that the best drying effect was achieved when maltodextrin,β-cyclodextrin,and gum arabic were added at 50%,10%,and 1.0%,respectively. Under this condition,the yield of powder was up to 36.25%and the moisture content in the powder was 5.49%.
