## 5 Conclusions
Calculated migration into food considering different partition coefficients: (a) diffusion coefficient DP = 1 \(\times\) 10\({}^{-10}\) cm\({}^{2}\)/s, (b) DP = 1 \(\times\) 10\({}^{-11}\) cm\({}^{2}\)/s, (c) DP = 1 \(\times\) 10\({}^{-12}\) cm\({}^{2}\)/s, (d) DP = 1 \(\times\) 10\({}^{-13}\) cm\({}^{2}\)/s, (e) DP = 1 \(\times\) 10\({}^{-14}\) cm\({}^{2}\)/s and (f) DP = 1 \(\times\) 10\({}^{-15}\) cm\({}^{2}\)/s. Calculated for a layer thickness of d = 100 \(\mu\)m, cP0 = 100 mg/kg, V = 1000 mL, A = 600 cm\({}^{2}\). Note: (e) and (f) different scale on y-axis; Figure S2.

Calculated for a layer thickness of d = 200 \(\mu\)m, cP0 = 100 mg/kg, V = 1000 mL, A = 600 cm\({}^{2}\). Note: (e) and (f) different scale on y-axis; Figure S3.
