The flavor compounds in green teas blended with citrus peels (lemon, sudachi, and mandarin) were extracted by the simultaneous distillations and extraction method. The concentrated flavor extracts were analyzed and identified by gas chromatography-mass spectrometry. The sweet flavor tended to increase in the citrus peel blended tea, and the increase was larger in the blended green tea than in the blended black tea. Therefore, the sweet flavor was supplemented by adding citrus peels to green tea. Mint and flower aroma were increased as common aroma characteristics of the citrus fruit peel-green tea blending, and especially, the citrus flavor was greatly increased. Limonene, which has a citrus flavor, is citrus fruits main essential oil component. ¥ã-Terpinene is a substance produced by the isomerization of limonene, which gives off a unique fragrance of citrus fruits. Myrcene is a component of many citrus peels obtained by thermal decomposition of ¥â-pinene and exhibits sweet balsamic aroma properties. In addition, ¥á-pinene and ¥â-pinene are fragrance substances that give off the note of pine.
