Food categories according to Commission Regulation EC No. 1565/2000 (EC, 2000) in FGE.06 (EFFA, 2002a). According to the Industry the "normal" use is defined as the average of reported usages and "maximum use" is defined as the 95th percentile of reported usages (EFFA, 2002i).
Note : mg/kg = 0.001/1000 = 0.000001 = 1/1000000 = ppm.
