everal alerts for food contamination caused by photo-

initiators, which are added to UVcurable inks to cure the ink

onto the substrate, occur in the past. In 2005, Italian authorities

withdrew thirty million liters of infant milk from the market due to

the presence of the photoinitiator 2-Isopropylthioxanthone. Since

then, other photo-initiators have also been found in foodstuffs.

Evaluation of the migration of photo-initiators in foodstuffs is

challenging due to the complexity of the matrix and the wide

variety of foodstuffs that need to be analysed. Therefore,

migration studies can be carried out using food simulants. The

official simulant for dry foodstuffs is poly(2,6-diphenylphenylene

oxide), also known under its commercial name Tenax®. In this

contribution, the performance of Tenax® as a simulant for dry

foodstuffs for the migration of photoinitiators from cardboard

packaging was evaluated. Therefore, the simulation according

to EU Regulation 10/2011 was compared to the real migration

conditions for dry foodstuffs. Important migration features such

as migration temperature, migration time, Tenax® pore size were

studied, supporting the suitability of Tenax® as a simulant for the

migration of photo-initiators towards cardboard from a consumer

safety point of view. Unfortunately, the use of the Tenax® powder

as a simulant is inconvenient since the powder has to be entirely

collected in a recipient prior to contaminant extraction. Therefore,

Tenax® films were synthesized that can be easily applied to the

cardboard surface. The performance of the films was compared

to the performance of the Tenax® powder for a selection of model

contaminants. It was concluded that the performance of Tenax®

as a simulant for the migration of photoinitiators from cardboard

towards dry foodstuffs was illustrated. However, the use of easy

applicable Tenax® films can open new perspectives in the domain

of testing food contact materials intended for contact with dry

foodstuffs for compliance.
