    Mineral oil migration from paper-based packaging into food, investigated by means of food simulants and model substances
    Mineral oil hydrocarbons (MOH) are known to be mixtures of non-identified substances, which can migrate from, inter alia, recycled food packaging into food products. Such substances may have carcinogenic potential, which leads to a need to avoid their migration into food. In this article, we investigate the possible use of food simulants and model substances to simplify migration approaches. Tenax and Sorb-Star were chosen as simulant media. To stage the action of known components as a replacement for the migration of MOH, 16 single substances, including n-alkanes and aromatic compounds, were used. Kinetic studies were carried out at a maximum of 60°C with contact times of up to 14 days in touching contact with a medium or in gas-phase transfer to it. The results demonstrated that migration was predominantly a function of temperature, time and contact type, but it was also dependant on the molecular weight and polarity of the substances. Due to their low polarity, alkanes showed higher migration to the lipophilic food simulants than did pure aromatics without alkylation. Additionally, alkylated aromatics represent mineral oil aromatic hydrocarbons (MOAH) more realistically. In contrast to Tenax in the gas-phase transition, Tenax in touching contact may lead to overestimated values at higher temperatures. Migration values for Sorb-Star are in similar regions for both contact types. However, the values of the touching contact experiments were slightly higher than those of the gas-phase transfer. The results for Sorb-Star and Tenax with transport solely over the gas phase are also in good agreement. Sorb-Star generally represents an optimal simulant for chunky foods, whereas Tenax seems a good simulant for food types with a high contact surface. Temperatures up to 40°C are appropriate for most types of migration experiments, whereas 60°C should only be used as an option for experiments with Sorb-Star.

    Migration and permeation of mineral oil components from paper-based food contact materials into foods - A critical comparison of analytical methods
    Mineral oil hydrocarbons (MOH) have been focused upon for their ability to migrate out of recycled, paper-based food contact materials. Their transfer into food products is controlled and predicted using various methods. This article provides insight into a variety of testing methods concerned with the migration and permeation of MOH. The influence of the experimental design and analytical approaches on the results is critically discussed. The research on and the potential of theoretical approaches by mathematical modelling are considered. Migration test conditions have not been regulated thus far. Those based on existing regulations dealing with polymers are generally inappropriate. In principle, there should be a focus on the application of food simulants and model substances. There is a wide range of barrier efficiency test methods for the adequate use of functional barrier materials. Permeation experiments, which result in physicochemical properties of the barrier, seem to be more suitable. Mathematical modeling has a high potential for simplifying the evaluation of the quantity of MOH in food.

    Das Bemühen der Lebensmittelwirtschaft und ihrer Zulieferbranchen geeignete Lebensmittelverpackungen einzusetzen, deren Beschaffenheit den potentiellen Übergang von Mineralölsubstanzen (MOSH und MOAH) oder Analogen auf die verpackten Lebensmittel nicht zulässt, war der Hintergrund für ein Projekt der Gemeinschaftsforschung auf der Plattform des Forschungskreises der Deutschen Ernährungsindustrie (FEI). Über 60 Verbände und Einzelunternehmen haben sich finanziell beteiligt und sich im Projektbegleitenden Ausschuss unter Federführung des BLL und des Bundesverbands der Deutschen Süßwarenindustrie (BDSI) engagiert. Die Projektnehmer und Forschungsstellen waren das Fraunhofer Institut für Verpackung und Verfahrenstechnik (IVV) Freising und das Institut für Systemverfahrenstechnik der TU München. Diese haben in drei Jahren intensiver Mess-, Modellierungs- und Zusammenarbeit das Projekt mit der gezielten Vorgabe eines praxisrelevanten Ergebnisses bewältigt. Projektziel waren die Entwicklung von Vorhersagemodellen zu bereits eingesetzten Lebensmittel-Verpackungslösungen und Hilfestellung zur Bewertung der Eignung bezüglich der MOSH/MOAH-relevanten Beiträge bzw. Beurteilung der Maßnahmen zur Minimierung oder Vermeidung der Produktbelastung durch neue Verpackungslösungen (wie Barriereschichten, Innenbeutel, Adsorberlösungen, Frischfaserverpackungen). Im Rahmen der Abschlusspräsentation zum Projekt am 31. Januar 2019 in Berlin konnte durch die Forschungsstellen das konkrete Ergebnis, eine Technische Leitlinie als neues Tool zur Vermeidung von Mineralöleinträgen an relevanten Stellen vorgestellt werden. Mithilfe dem in dieser Leitlinie verfolgten Konzept können Unternehmen in einer gestuften Vorgehensweise ohne Messungen auf dem mathematischen ""Modelling"" beruhende Annahmen zum MOH-Übergang berechnen und Freigabeentscheidungen treffen. Bei komplexeren Fragestellungen sind Migrationsmessungen erforderlich nach den im Projekt angewandten Methoden bei IVV. Die 52-seitige Leitlinie wurde vom BLL redaktionell bearbeitet und steht Interessierten kostenfrei als Druckfassung oder als Download-Version zur Verfügung.

    The aim of this research study is to evaluate the effectiveness of starch-coatings for preventing food contamination from paperboard packaging. Specifically, regarding the migration phenomena of n-alkanes and Mineral Oil Saturated Hydrocarbons (MOSH). Migration test series were performed under varying conditions (kinetics up to 5 days, at 40 and 60 °C) using spiked model substances (n-alkanes mixture: C10-C40) and Tenax® as food simulant. The results obtained for neat paperboard showed that at 40 °C, alkanes from C18 to C26 and at 60 °C from C18 to C28 can migrate almost for 5% of the original spiking. Migration testing of starch-coated paperboard was evaluated, considering the effect of different ingredients and discussed together with the information gained by micro-structural observations. Results for coated paperboards demonstrated significant barrier properties compared to neat materials at the tested conditions. Finally, migration test series with originally contaminated materials were carried out.
