Abstract

With thousands of years of history, tea has become the most consumed flavored beverage all over the world. Tea is separated into three large groups -- green, black and oolong tea -- based on the fermentation of tea leaves and taste. Large number of studies have indicated that the well-known health benefits is contributed by the polyphenol compounds, a group of antioxidants, in tea. To enhance the taste of tea typically various additives can be incorporated. Historically, in western countries milk and sugar and in eastern countries spices such as cinnamon, clove and ginger were added to tea. Studies have shown that additives such as milk and sugar may reduce the total antioxidants capacity of tea. Spices, on the other hand, are famous for their antioxidative characteristic independent of tea. However, not many studies focus on the antioxidant properties of these spices similar to antioxidant studies of tea. The aim of this study is to qualitatively identify the polyphenols of interest in spiced black tea by using techniques such as high-performance liquid chromatography (HPLC) and liquid chromatography mass spectrometry (LC-MS).
