Migration of mineral oil aromatic hydrocarbons (MOAH) from cardboard containers to dry food and prediction tool

Kinetics of Organic Volatile Desorption from Cellulose-Based Materials

“…Although diffusion models served well for particular application cases, ,− these models fail in many instances that involve fibrous cellulosic materials . The migration process in fiber-based substances differs from that in, e.g., plastics .…”

“…A careful choice of the model compounds is called for, since the desorption of VOCs from paper depends on the complex interplay of diffusion, sorption exchange between pores and fibers, and, possibly, chemical reactions. The significance of each of the mechanisms playing its role during the transport is anticipated to heavily rely on the polarity, boiling point, and chemical structure of the volatile substance. ,, Table gives an overview of all 10 model compounds and their relevant physical properties such as boiling temperature, dipole moment μ, and molar mass.…”

“…It was concluded that the partition coefficients depend not only on the boiling point of the compound but also on its chemical structure, polarity, and the chemical interaction with the given pulp. Jaen et al 8 used established testing methodologies to explore the viability of dry food simulants and to perform a partial least-squares regression model to predict the worst-case migration values. This study used 16 different aromatic hydrocarbons as representative substances for mineral oil hydrocarbons (MOAH), encompassing a broad spectrum of molecular weights and chemical configurations.…”

“…The significance of each of the mechanisms playing its role during the transport is anticipated to heavily rely on the polarity, boiling point, and chemical structure of the volatile substance. 8,11,23 Table 1 gives an overview of all 10 model compounds and their relevant physical properties such as boiling temperature, dipole moment μ, and molar mass.…”

“…A number of studies have addressed the transport of various substances through and from paper materials into a contact medium. ,− The combined findings of these studies suggest diverse scenarios and demonstrate the complex nature of VOC release from paper. Not only the properties of the volatiles to be released but also the type of interface through which the release occurs has a critical influence.…”
