MOAH

Chemical Composition

Alkylated rings form the primary structure of these molecules and distinguish them from saturated varieties. Presence of moah in a plastic part often indicates the use of low grade process oils or contaminated regrind. The complexity of the mixture makes individual compound identification difficult.

Migration Risk

Transfer of these chemicals from the packaging into the food depends on the temperature and the nature of the contents. Because moah are lipophilic they move more readily into fatty foods like chocolate or butter. Barrier layers are often required in multilayer films to prevent this movement.

Analysis Requirement

Testing protocols involve liquid chromatography followed by gas chromatography to separate the aromatic fraction. Measuring moah levels is a critical step in the safety assessment of recycled plastics intended for food contact. Strict limits are being established to protect consumers from long term exposure.

Food safety labs use highly sensitive detectors to identify these compounds at the parts per billion level. This monitoring is a key part of the quality assurance process for any manufacturer using recycled polymer content.
