摘要
为确定日常冲泡平山雨花茶的最佳工艺条件,该试验以2018年生产的南京平山雨花茶作为原料、模拟日常饮茶的冲泡习惯,运用水提法,研究不同冲泡温度、冲泡时间、料液比、浸提次数对平山雨花茶茶多酚释放含量的影响;运用正交试验方法确定冲泡雨花茶的最适条件。研究结果表明使用自来水,在冲泡温度90℃、冲泡时间8 min、料液比1∶110(g/mL)条件下冲泡的茶汤茶多酚含量最高,提取率为17.91%。
In order to determine the daily brew hirayama made yuhua district tea the best process conditions,the experiment to 2018 years in the production of nanjing hirayama made yuhua district bubble tea as raw materials,simulation of the daily tea drinking habits,the use of water,different brewing temperature,brewing time,liquid ratio,extraction times of hirayama made yuhua district the effects of tea polyphenols release content;The optimal conditions of the tea were determined by orthogonal experiment,and the sensory evaluation was made on the tea soup with different conditions.The results of the study indicate that tap water was used in the brewing temperature of 90℃.The maximum amount of polyphenols in the tea soup with 8 minutes of infusion time and liquid material ratio of 1∶110(g/mL)was 17.91%.
