Data are expressed in mg L−1 (of juice) are expressed as the means ± SD of three independent experiments. Different letters in each row indicate a difference at a significance level of p = 0.05.
LOD- limit of detection- the lowest concentration of the analyte that can be detected by applied method, calculated as 3 time signal to noise ratio.
