绞股蓝荷叶复配茶包研发

以荷叶和绞股蓝为主要原料,对荷叶与绞股蓝复配比例、过筛目数、水的添加量和冲泡时间4个因素进行单因素试验,并根据单因素试验结果,设计L9(34)正交试验.结果表明,绞股蓝荷叶复配茶包最佳工艺配方为:荷叶添加量与绞股蓝添加量的比例为1:4、过筛目数为70μm、水添加量为150 mL、冲泡时间为7 min,此条件下的荷叶绞股蓝复配茶包感官评分最高,为95分.

Research and Development of Gynostemma Pentaphyllum Lotus Leaf Compound Tea Bag

Taking lotus leaf and Gynostemma pentaphyllum as the main raw materials,the four factors of lotus leaf and Gynostemmapentaphyllum compound ratio,sieving mesh number,water addition amount,and brewing time are used as single factor experiments.According to the single factor experiment results,design L₉(3⁴) orthogonal test.The results show that the best technological formula of Gynostemma pentaphyllum and lotus leaf compound tea bag is that the ratio of lotus leaf to Gynostemmapentaphyllum is 1:4,the sieving mesh number is 70 μm,the amount of water added is 150 mL,and the brewing time is 7 minutes.The sensory score of the Gynostemmapentaphyllum compound tea bag under this condition is the highest,which is 95 points.
