| 摘 要： | 为了探明普洱老茶饮用的安全性,以贮藏多年的陈香普洱茶为原料,以未渥堆发酵的普洱茶为对照,采用国家标准测定方法对其主要的品质安全性指标进行评价和分析。结果表明,在本研究范围内未检测出致病菌如黄曲霉素、致泻大肠埃希氏菌、大肠杆菌和金黄色葡萄球菌,有1个样品检出沙门氏菌;样品农残检出值为0;重金属铅的含量在0.55 mg/kg～4.43 mg/kg范围内,除1个样品外,其余铅含量均符合茶叶卫生标准和食品中污染物限量要求;总灰分含量范围在6.176%～9.411%,水不溶性灰分含量范围在2.44%～5.217%,大部分样品的水溶性灰分占总灰分的50%以上,酸不溶性灰分含量较低,在0.161%～1.815%范围内,说明茶叶中沾染的泥沙较少,品质较好。
