Decaffeination and tea is a subject that has long been misunderstood not only by consumers but also by industry professionals. I was taken by surprise when I recently read an excerpt from a newly released book, written by highly recognized tea industry professionals, that was clearly inaccurate when it came to the topic of decaffeination processing and tea.
I began questioning my own information on decaf processing and decided the best thing to do was to verify what I believed to be true. I decided to talk with the definitive authority on the subject, Joe Simrany, President of the Tea Association of the USA, Inc (TAUS).
I soon was relieved to learn that my critical information was indeed correct although some of the details need fixing. So here is what I learned. Unlike what I thought, decaffeination processing is not regulated by the FDA and adhering to industry standards is completely voluntary. The FDA does not have its own set of guidelines but relies on the expertise of the Tea Association Technical Committee (TATC) for the best practices. There is no sanction, legal or otherwise, for non-compliance. So what happens if a group is distributing decaffeinated tea that does not meet the standard? The first line of defense is the TAUS, who would attempt to correct the issue diplomatically. If that was unsuccessful the FDA would be notified and would follow up to see that the necessary changes to processing were made. So what do those guidelines consist of?
The Guidelines
Teas labeled Decaffeinated will contain no more than 0.4% caffeine on a dry weight basis.
Caffeine Free Tea is an inappropriate labeling term for any tea regardless of the degree of decaffeination processing.
There are currently only 2 methods approved for decaffeinating tea leaves, solvent extraction using ethyl acetate and carbon dioxide in the supe[1] [2] [3] 下一页 更多英语知识学习请访问:英语学习
