Interpretation of the migration of benzophenone type photoinitiators into different food simulants and foodstuffs in terms of the physicochemical properties of the migrants

Publication date: March 2020Source: Food Packaging and Shelf Life, Volume 23Author(s): M.P. Elizalde, J.L. Aparicio, M. RincónAbstractThe migration of three different photoinitiators, benzophenone (BP), 2-hydroxybenzophenone (2-HBP) and 4-hydroxybenzophenone (4-HBP), from spiked paperboard into the food simulant Tenax® as well as into Porapak® and Tylose®, are compared to their migration into infant milk and creamer powders as well as into lyophilized skimmed, semi-skimmed and whole fat milks. Porapak® shows similar migration behaviour to Tenax® whereas slightly lower migration into Tylose® is observed. In all simulants and foodstuffs the migration sequence is: 2-HBP > BP>4-HBP, with a markedly lower migration of 4-HBP into the simulants. In most cases, the migration into the simulants is significantly higher than that into the foodstuffs. The order of overestimation for the three food simulants is BP> 2-HBP> 4-HBP. An interpretation of the results in terms of the physicochemical properties of the migrants and the fat content of the foods is given. No advantages have been concluded by using Porapak® and Tylose® as alternative food simulants to Tenax® for high fat content foods.
