摘要
研究了均质条件、固形物含量和进风温度对粉末植脂奶油产品性质的影响,并进一步利用正交试验对工艺条件进行了优化。结果表明,制备粉末植脂奶油的最佳工艺条件为:50 MPa均质2次,固形物含量50%,进风温度180℃。在最佳工艺条件下,粉末植脂奶油的包埋率达到89.49%,产品为乳白色,颗粒细小均匀,溶解性好。与传统植脂奶油相比,该粉末植脂奶油复溶乳状液平均粒径增大,打发倍数略低于传统植脂奶油的,但二者的质构特性无显著差异。
The influences of homogenization condition, solid content and inlet air temperature on proper- ties of powder non - dairy whipped cream were investigated. The optimal process conditions for preparing the powder non - dairy whipped cream were determined by orthogonal experiment as follows： 50 MPa homogenization for twice, solid content 50%, inlet air temperature 180 ℃. Under the optimal conditions, the embedding rate was 89.49%, and the product was milky white with fine uniformity and good solubili- Compared with the traditional non - dairy whipped cream, the powder non - dairy whipped cream wa- ter emulsion had larger mean particle size, and lower whipping times, but their texture characteristics had no significant difference.
