红茶咸香饼干加工工艺的研制

The development of processing technology for black tea-salty sweet-biscuits

研究红茶咸香饼干加工工艺。分别通过单因素实验确定了红茶的制备工艺和红茶的冲泡工艺,红茶制备采用鲜叶→萎凋(室温)→机械揉捻→轻发酵(35℃×3h,湿度90%)→烘干的制备工艺方案;红茶的冲泡采用洗茶→纯水仪过滤水冲泡(95℃×5min)→茶叶与茶汤分离→出茶的冲泡方案。利用正交实验确定了红茶咸香饼干的最佳配方为:低筋面粉180g、盐2g、泡打粉1.5g、黄油45g、红茶汤45g、全蛋液30g。

We researched the processing technology of black tea-salty sweet-biscuits.The preparation and brewing process of black tea were determined by single factor experiment and the preparation process program was that, fresh leaves→withering （room temperature）→→mechanical rolling→light fermentation （35℃ X 3h,humidity 90%）→drying.The brewing process was that washing tea→brewed by filtered water of pure water meter（95℃×5min）→separating the tea and tea soup.And then,the best formula of black tea-salty sweet-biscuits was confirmed by an orthogonal experiment, the best technical skill was that low-gluten flour 180g, salt 2g, baking powder 1.5g, butter 45g,black tea soup 45g, whole egg 30g.
