我看很多人都講的頭頭是道
說熟茶安全，不入倉茶也安全
卻完全提不出證據說他們到底哪裡安全

真是空嘴嚼舌

熟茶和不入倉茶真的安全？

好吧
也許熟茶和不入倉茶在剛出廠的時候真的安全
但是一段時間後
肯定也有生菌和黴菌
而且數量不一定比你們眼中視為骯髒的入倉茶少啦

請看這個表吧

人體在千萬年的演化中已經學會與黴菌共同相處
除了體質敏感者偶爾會過敏外
對黴菌基本上是免疫的

你這麼說～顯然又與你所引用之～”黃助教”（生來飲茶人．ｘｙｚ．義大利）

的說法不同囉～依你的說法”黴菌”對人體無關緊要～他卻說醫院可以驗菌～而且很便宜

若無關緊要～醫院又為何要驗明菌種呢？

菜鳥兄實在太菜，我都懶得回了

請問
如果你老婆懷孕，會不會去醫院驗性別（醫院應該有這項服務吧？）

你老婆都已經懷孕，是男是女已成定局，驗了又不能改變結果
醫院為何要提供這項服務？

有錢賺，醫院又有何不能提供的服務？

Abstract

In recent years the consumption of tea and herbal infusions has increased. These hot drinks are consumed as daily drinks as well as for medicinal purposes. All tea varieties (white, yellow, green, oolong, black and puerh) originate from the leaves of the tea plant, Camellia sinensis. All extracts made of plant or herbal materials which do not contain Camellia sinensis are referred as herbal infusions or tisanes. During processing and manufacturing fungal contamination of the plant materials is possible, enabling contamination of these products with mycotoxins. In this study a multimycotoxin UPLC−MS/MS method was developed and validated for the analysis of the raw tea and herbal infusion materials as well as for their drinkable products. The samples were analyzed by ultra-high-performance liquid chromatography−tandem mass spectrometry (UPLC−MS/MS), with a mobile phase consisting of variable mixtures of water and methanol with 0.3% formic acid. The limits of detection for the different mycotoxins varied between 2.1 μg/kg and 121 μg/kg for raw materials and between 0.4 μg/L and 46 μg/L for drinkable products. Afterward 91 different tea and herbal infusion samples were analyzed. Only in one sample, Ceylon melange, 76 μg/kg fumonisin B1 was detected. No mycotoxins were detected in the drinkable products.

Keywords (keywords): Multimycotoxin; UPLC−MS/MS; tea; herbal infusion; fumonisin B1

烏大,謝謝提供本文,除了錫蘭_茶??會染B1毒素,其他茶飲藥飲類並未發現感染任何黴菌毒素,研 ...

要看整份論文要錢的，好像是30美金，既然是學術論文，至少有研究方法和數據，總比我們這群人空口嚼舌好多了

再貼一個論文
這個論文是咱們嘉義大學發表的，主題是普洱茶的抗誘變和抗菌性



Abstract
The biological action of water extract of pu-erh tea (WEPT) was evaluated by Salmonella mutagenesis assay and bacteria test. Like
green tea, oolong tea and black tea, WEPT showed neither cytotoxicity and nor mutagenicity toward Salmonella typhimurium TA98 and
TA100 with or without S9 mix (an external metabolic activation system). WEPT at 0.5–5 mg/plate expressed a dose-dependent inhibitory
effect against both the mutagenicity of aflatoxin B1 (AFB1), an indirect mutagen which requires metabolic activation, and 4-
nitroquinoline-N-oxide (NQNO), a direct mutagen, in Salmonella typhimurium TA98 and TA100. In general, the antimutagenic activity
of WEPT against AFB1 and NQNO was weaker than other tea extract because of the least amount of total catechin in WEPT. For
antimicrobial action, WEPT, green tea, oolong tea and black tea at 2.0 mg/ml showed inhibitory effect on growth of Staphylococcus
aureus and Bacillus subtilis, but no effect on Escherchia coli. Obviously, WEPT has potential antimicrobial effect on gram-positive
Staphylcoccus aureus and B. subtilis than that of gram-negative E. coli. In addition, caffeine and epicatechin (EC), main polyphenolic
compounds in WEPT, showed both antimutagenic and antimicrobial effect against strains mentioned above, which may partially
account for the antimutagenic and antimicrobial action of pu-erh tea.
