TL;DR: The objective was to demonstrate the potential of synchrotron X-ray analysis to detect morphological alterations that can occur in barrier packaging materials and structures, and no significant structural changes were observed in the EVOH structures after high-pressure processing treatment.

TL;DR: Mass transport of six food aroma components through three sealable polymer films suitable for direct food contact, ultra-low-density polyethylene (ULDPE), ionomer (ION), and modified polyester (mPET), was analyzed by permeation experiments and shows that ULDPE is more permeable to aromas that ION, which is more so than mPET.

TL;DR: The results showed that aroma scalping is highly dependent on the fatty food simulant utilized and PET was the packaging film which showed the lowest partition coefficient for non-polar components while ULDPE showed the highest partition for polar aromas.

TL;DR: Isostatic and quasi-isostatic permeation experiments were used to characterize the permeability of 1-hexanol through polypropylene films as discussed by the authors, and the quasi- isostatic method was considered as an isostastic experiment at the limit a of null purging stream flow rate.

TL;DR: The measurement of liquid/vapour equilibrium can be regarded as a powerful tool to compare the effectiveness of food simulants as substitutes of a particular food product and can be used as a guide for the selection of the appropriate simulant.
