“喝普洱茶致癌?”茶院士駁斥 |

“喝普洱茶致癌?”昨日,新浪微博認證用戶“人體工程學李建軍教授”在微博中提及,喝普洱茶最容易得癌症,茶裡有大量的致癌物“黃曲毒素”。
該言論引起不少愛喝普洱茶網友的關注。
昨日,被稱為茶院士的中國工程院院士、中國農業科學院茶葉研究所研究員陳宗懋力挺普洱茶,稱曾有多地對普洱茶測定過,只有極個別樣本發現過微量的黃曲黴毒素,其微量根本不構成致癌威脅。
普洱致癌說引發大討論
“喝普洱茶是得癌症最快的方法,因為放了太久,裡面有大量的黃曲毒素是致癌物。”“人體工程學李建軍教授”的這條微博激起千層浪,曾被世人稱讚的普洱茶,突然被冠上了“致癌”的稱號,引發了網友討論。
截至昨日19時30分,該微博已被轉發5962次,千餘名網友參與評論。很多人求證此說法的真假,個別網友很是擔憂,也有網友認為是無稽之談,要博主拿出證據再說話。更有普洱愛好者和茶商在評論中叫板李建軍。
新浪微博實名認證為“世界茶文化交流協會名譽會長”的“茶人王心”發評論稱,黃曲黴大量存在於空氣和食物,在堅果植物、大米等中易轉變為黃曲黴毒素。但全世界的實驗室中尚未發現茶中的黃曲黴能轉化成黃曲黴毒素。
營養師駁斥“普洱致癌說”
網絡搜索發現,“普洱茶致癌說”幾年前便有,昨日,記者試圖聯繫李建軍,截至昨日18時,李建軍未回應。
昨日,知名營養師顧中一在果殼網發文駁斥“喝普洱會最快致癌”。顧中一介紹,黃曲黴毒素主要是黃曲黴菌和寄生曲黴菌的代謝產物,被世界衛生組織(WHO)列為I類致癌物。由於普洱茶是後發酵,特別是濕倉儲存的過程中會出現黴變的可能,受到真菌毒素污染,這些毒素中就包括黃曲黴毒素。
“談到致癌物不談劑量,都是在耍流氓。”顧中一指出,根據美國的規定,除奶製品之外,所有食物中的黃曲黴總量不超過20ppb。儘管目前我國對茶葉中黃曲黴毒素B1的限量標準尚未制定,但普洱茶導致癌症的風險並不高,無需擔心。

“茶院士”陳宗懋
“普洱茶致癌不可能”
昨日,素有“茶院士”之稱的陳宗懋院士稱,過去很多地方對普洱茶中是否含有黃曲黴毒素做過測定,只在極個別的樣本中發現過,而且含量非常低。“有害的東西沒到量就不構成毒害,普洱茶致癌是絕對不可能的。”
陳宗懋院士解釋,普洱茶由生茶變成熟茶,要經過好幾年時間,在這個過程中,需要幾種菌群參與發酵,從而構成普洱茶的香味。這幾種參與發酵的菌群均是有益菌群,沒有黃曲黴菌。(來源:新京報) |

金花是什麼?
按照中國國家標準:金花是灰綠麯黴的金黃色孢子,金花越多品質越好。金花能分泌澱粉酶和氧化酶,可催化茶葉中的澱粉轉化為單糖,催化多酚類化合物氧化,使茶葉湯色變棕紅,消除粗青味。金花...冠突散囊菌,是益生菌,目前只有黑茶類的茯茶才會要求製作時刻意培養此菌種,要一定的茶梗與葉片黃金比例且鬆緊適度以營造空間利於滋生,這道工序又稱"發花",是屬於國家機密,優質茯茶金花普茂,日本人早已對此茶的"益生菌"視為珍寶且於十年前就引進供其國人飲用。
金花的作用:金花能產生一種酶 ....
