普洱茶三七口服液的研制*

 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

The Development of Pu-erh Tea Panax notoginseng Oral Liquid

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.
