| 摘 要： | 针对杜仲雄花茶在加工过程中易变色的问题,通过利用盐离子、柠檬酸、抗坏血酸和杀青等处理抑制杜仲雄花的褐变以实现护绿的效果.在单因素试验基础上,利用SAS数据统计软件对影响杜仲雄花茶汤色的因素进行了评价,筛选出具有显著护绿效应的3个因素,即Zn~(2+)、柠檬酸和蒸汽法杀青.利用Design-Expert数据分析软件中响应面分析法的中心组合设计建立了杜仲雄花茶加工过程中护绿工艺的数学模型,并确定了杜仲雄花茶加工过程中适宜的护绿工艺为:先用料液比为10g/mL、质量分数0.04%的Zn~(2+)水溶液和0.4%的柠檬酸水溶液喷洒杜仲雄花蕾,然后在蒸汽中蒸40s,经过处理后的材料制成杜仲雄花茶,可避免加工过程中变色和品质变差. |

| Abstract: | Aimed at the discoloration problems in processing of eucommia male flower tea,color protection treatments such as salt ions,citric acid,ascorbic acid,and deactivation of enzymes were used to inhibit the browning.The influencing factors on the liquor color of the male flower tea were evaluated based on the single factor experiment by using SAS software.The concentrations of Zn~(2+) and citric acid for flower preparation and the duration for flower steaming were selected as the main effect factors.The mathema... |
