摘要
以普洱茶和三七皂甙为主要原料,对普洱茶浸提液的澄清工艺进行研究,通过研究澄清剂的不同添加量、茶汤pH、茶汤温度、静置时间,测其透光率,选择出最适的澄清工艺条件;通过配方筛选选择出最佳配方;并对普洱茶三七口服液进行稳定性实验和对其质量指标进行研究。结果表明:每升普洱茶三七口服液中加入4 g三七皂甙、20 g普洱茶、9.45 mL/50 mL的蜂蜜、0.05%Vc,经115℃20 min灭菌处理,其感官品质最佳;普洱茶三七口服液在37~40℃,相对湿度为75%的条件下保存90 d,其感官指标、理化指标符合产品的质量标准,微生物指标符合产品的卫生标准,推测普洱茶三七口服液在常温下保质期达2年。该研究结果为普洱茶多元化开发提供了新途径。
Adopting food processing technology,Pu-erh tea Panax notoginseng oral liquid was successfully developed,using Pu-erh tea and arasaponin as the main raw materials,and its stability was researched to determine its shelf life.Clarification process of Pu-erh tea extract was researched,namely transmittance as index for investigation,the optimum clarification process parameters were determined,including concentration of clarifier,pH value and temperature of Pu-erh tea extract,standing time;and then the best formula,stability and quality indexes of Pu-erh tea P.notoginseng oral liquid were also researched.The result showed that 4 g of arasaponin,20 g of Pu-erh tea,9.45 mL/50 mL of honey and 0.05% of vitamin C were added to per liter of Pu-erh tea P.notoginseng oral liquid,which was sterilized at the condition of 115 ℃ 20 min,and its sensory quality was the best.Under the circumstances of 37~40℃ and relative humidity of 75%,Pu-erh tea P.notoginseng oral liquid was preserved for 90 days and its sense indexes,physical and chemical indexes and microbial indexes complied with product standard.Therefore,the shelf life of Pu-erh tea Panax Notoginseng oral liquid was 2 years.
