目的优选速溶药茶颗粒提取液的最佳干燥方法及成型工艺,使其最大限度地保留茶香,口感最好;使该制备工艺科学、合理、可行。方法以药茶中最不稳定成分茶多酚的含量作为评价工艺的指标,采用福林酚法测定药茶中茶多酚的含量,采用正交设计实验法优选药茶喷雾干燥的最优工艺参数,再用完全随机t检验比较喷雾干燥法和冷冻干燥法药茶中茶多酚的损失量;以口感、外观等为评价指标,采用等级一致性检验法筛选速溶药茶颗粒最优成型工艺。结果药茶最佳喷雾干燥工艺参数为药液温度为50℃,进风温度为120℃,泵药速度为5 m L/min,通针次数为5次/min。喷雾干燥较冷冻干燥药茶中茶多酚损失少。制粒中不加任何辅料,仅...

Objective To optimize the desiccation method and forming process of the extracting solution of instant herb tea particle, the tea perfume was mostly maintained and the tasting was the best. To make the preparation technology is scientific, reasonable, and feasible. Method The most unstable component-tea polyphenol was as the evaluation index of the technology. The content of tea polyphenol in herb tea was determined by Folin-phenol reagent method. The technological parameter of spray drying of herb tea was optimized by orthogonal design, compar...
