What Looks Interesting

The Handbook of Green Tea and Health Research is new to me, it looks like a decent read but have not had a chance to see a copy of it yet. There are a few articles from it listed below.

• Aroma Characteristics of Cocoa Tea (Camellia ptilophylla Chang), Wang Xiujuan; Wang Dongmei; Li Jiaxian; Ye Chuangxing; Kubota Kikue, Bioscience, biotechnology, and biochemistry (2010), 74(5), 946-53.

This article does some GC-MS work to find out what the volatile compounds (what you can smell) in Cocoa tea are, some of my favorite descriptions are sweet, cigarette-like and old paper like.

• Toxic and essential mineral elements content of black tea leaves and their tea infusions consumed in Iran, Salahinejad Maryam; Aflaki Fereydoon, Biological trace element research (2010), 134(1), 109-17

What’s so special about teas available in Iran? Well, apparently they have a tiny bit more copper and nickel. They also are not able to measure the low levels of toxic metals and conclude that tea is generally safe for consumption. It’s a good thing I waited for this paper to start drinking tea.
