喝普洱茶请小心了哦!台湾农委会茶业改场长廖庆梁说，中国云南出产的普洱茶近年席卷香港 、台湾，变成抢手的茶叶，但学者专家调查，普洱 茶因特殊制程、陈年储藏环境等因素，使 其总生菌数高的吓人，必须煮沸才得以完全消灭，一般人单用开水冲泡的饮茶方式，对人体可能有害。廖庆梁说，云南出产的普洱茶近年来被渲染成具有神奇保健疗效的 茶叶，对肠胃尤其有益等，使港台一带掀起一股普洱茶热，人手 一杯，且早、中、晚不停喝，部分人士更认为，喝得愈多，对身体愈佳，事实上大谬不然。 廖庆梁解释，普洱茶属于后发酵茶，是将茶菁经杀菁、揉捻、干燥等手续后，堆置在仓库中称为渥堆，使茶叶内部多酚类化合物氧化，其氧化可分自动氧化、酵素性氧化、曲菌氧化等三种不同方式。 廖庆梁说，普洱茶后发酵堆置仓库有干仓及湿仓二种，前种为自动氧化作用与酵素氧化作用二者混合并行，后者则加上曲菌氧化作三者混合进行，市面上出售的普洱茶，其 贮存年限有五年、十年、甚至四、五十年以上者，业者常标榜陈年普洱，愈陈愈香，更增医疗保健效果，并抬高售价。事实上，廖庆梁调查，普洱茶在产地云南西双版纳、孟腊等边疆地区，居住环境都离干净清洁有一大段距离，何况茶叶经长时间贮存，是否能维持好卫生安全质量？值得怀疑。 廖庆梁引用中兴大学食品科学系教授区少梅的研究报告指出，从普洱茶微生物的分析结果显示，其总生菌数与霉菌数高的惊人，如五年特选普洱茶，散茶总生菌数每公克有一点廿六乘以十的六次方菌落数，霉菌数则每公克有一百十五个菌落数。 廖庆梁说，早年普洱茶是运往中国西北地区作为蒸煮调制奶茶的原料，均经高温杀菌后再饮用，不会出问题，但现在人们均习惯用小壶冲泡方式来饮用，则大大不妥，不但无法增进健康，反对身体有害。 廖庆梁郑重警告，饮用普洱 茶，务必以高温充份煮沸为宜，例如以传统中药煎煮后饮用，亦可增加安全性，避免感染。 Drink Puer tea carefully, Oh !
