^aTissue–peel ratio value was calculated as follows; (dividing the content of each PMF in a specific tissue by its content in the orange peel) × 1000 × 100. The factor of 1000 was used because the concentration unit of the orange peel (ppm) is 1000 times higher than that of the tissue. The factor of 100 was used to obtain a percentage.
