Migration of Photoinitiators in Food Packaging: A Review

“…A difference in diffusion coefficient of six orders of magnitude can be concluded between the worst barrier to diffusion, LDPE, and the best one, PET. The poor barrier to benzophenone migration achieved by polyethylene has been experimentally concluded, for example, by Johns et al 18 and by Choi et al. 56 In this last case, not only for benzophenone but also for the migration into water of other polar surrogates studied by those authors.…”

“…However, the finding of benzophenone by Johns et al 19 in packaged frozen foods before microwave heating shows that migration can be not so minimal in some cases. This idea is confirmed by the same author 18 for benzophenone and other model ink components, which can migrate into foods stored at À20°C, even when the packaging is not in direct contact with the food or is polyethylene-coated. Additionally, the Food Standards Agency study on Benzophenone and other model migrants 64 demonstrated that migration of low molecular weight substances into chilled and frozen foods can be quite extensive.…”

“…Early in the 90's, Woods 16 already considered that benzophenone could permeate through printed paperboard. Johns et al confirmed it 17 and also found that benzophenone could migrate to the packaged food even from polyethylene coated board 18 because of the permeability of polyethylene to low molecular weight substances. Table 2.…”

Odorous compounds in paperboard as influenced by recycled material and storage

“…11 Benzophenone is used as a photo-initiator for UV-cured inks and was recently found to migrate to packaged food. 12 Benzothiazol may arise from anticorrosives in waste material. Diethylphthalate is a commonly used softening agent.…”
