*PDI, probable daily intake; TDI, total daily intake; *PDI = C × Cd/b.w., where: C is the concentration of OTA or OTA + 2′R-OTA in coffee/cocoa; Cd is the average daily consumption of coffee/cocoa in the given country, and b.w. is the mean body weight (70 kg). If the measurement for any analyte was below the LOQ, the value LOQ/2 was taken in calculations.
