摘要
速溶茶产品的稳定性问题影响市场销售,为了能大批量生产出高稳定性速溶普洱茶,本试验以云南普洱茶为材料,研究高稳定性速溶普洱茶粉加工工艺参数。在加工过程中,浸提2次,提取温度为70～75℃,添加茶叶量10%左右的β-CD环状糊精,茶水比1:20,并且陶瓷膜过滤时茶汤制冷温度30℃以下,陶瓷膜过滤后茶汤制冷温度17～18℃,静置充分,可生产出高稳定性速溶普洱茶。应用该工艺生产出的速溶普洱茶稳定好,适合作为罐装茶水的加工原料。
The stability of instant tea product affected the market sales,and the aim was to produce mass instant tea with high stability.Utilizing Yunnan Pu-erh tea as materials,the processing technology parameters of instant Pu-erh tea with high stability was studied.The instant Pu-erh tea with high stability was obtained by following processing technology parameters.The temperature was at 70-75℃,twice extract with 1：20 of the ratio of tea to water,adding β-CD cyclic dextrin about 10% of tea quantity.Tea liquor cooled to 30℃ before ceramic membrane filtering,and then cooled to 17-18℃ for standing sufficiently after ceramic membrane filtering.The Instant Pu-erh tea by this processing technology met the requirement of material for processing soft tea drink.
