Determination of Essential Mineral Concentrations in Some Turkish Teas and the Effect of Lemon Addition

다국어 초록 (Multilingual Abstract)

Essential elemental concentrations of Turkishblack, green, and earl grey tea infusions were determinedwith and without added lemon. Daily percentage elementalintake values from these 3 teas with and without lemonaddition were calculated based on Recommended DietaryAllowances (RDA). Calcium (Ca), cobalt (Co), copper(Cu), iron (Fe), potassium (K), magnesium (Mg), sodium(Na), selenium (Se), and zinc (Zn) concentrations wereincreased after lemon addition. The chromium (Cr)concentration was decreased in green and earl grey teasand increased in black tea after lemon addition. Themanganese (Mn) concentration was increased in green teaand decreased in black and earl grey teas after lemonaddition. The phosphorus (P) concentration was increasedin earl grey and green teas, and decreased in black tea afterlemon addition. The daily intake value of Mn was foundabove the RDA value.
