摘要
以信阳毛尖为材料,通过单因素及正交试验,进行从信阳毛尖中提取咖啡因的工艺优化研究。结果表明:最佳的提取工艺为乙醇浓度为80%,提取时间为3 h,沉淀剂为氧化钙,咖啡因提取得率为0.594%。
In this experiment, using Xinyang Maojian tea as material, singl~： factors and the orthogonal design experiment were designed to study the optimum technology of extraction caffeine.The result showed that the best technology of extraction of caffeine from Xinyang Maojian tea was 3 hours, 80% ethanol and CaO （precipitating agent ） .Through the best technology of extraction, the crude caffeine yields was 0.594%.
