| 摘要： | 一种茶多酚的提取方法，包括以下步骤：(1)茶叶预处理；(2)破壁：将备用茶叶在粉碎机中粉碎制取茶粉，与柠檬酸水溶液按照1茶粉kg : 20～40L混合，先微波浸提，然后加入木质纤维水解酶超微粉酶解；接着加入果胶酶超微粉和木聚糖酶超微粉酶解，之后煮沸；(3)提取：在反应釜中将步骤(2)所得酶解液以压力0.5～0.8MPa，温度90～100℃下提取10～15min，然后在超声功率80～100W下提取5～8min，过滤去渣，接着过滤液进行离心，收集上清液，加入柠檬酸调节pH，乙酸乙酯萃取；(4)浓缩、干燥：将步骤(3)所得萃取液经脱溶、喷雾干燥，即得茶多酚产品。本发明的优点在于茶多酚提取率可达33.0～35.5％, 纯度为98.6～99.1％, 咖啡碱含量为0.0513～0.0664％。 |
