What are the methods of food permeations?
Answers
Highlights
•
The interactions between paper samples and volatile compounds were investigated using three experimental setups.
•
. Adsorption and permeation experiments with paper samples and permeation experiments with paper samples and MPPO were used.
•
The test setup was complex and many factors influenced the results.
•
Paper cannot entirely be considered as a permeable barrier.
Paper is used in many different applications, due to its numerous favourable characteristics.
An inherent property of paper is its porosity. One of the main effects of this porosity is that it allows the possibility of mass transport through it.
In this work, we describe a study that was carried out to simulate the transport of substances relevant for food contact applications through paper using adsorption/desorption experiments and permeation experiments in migration cells.
The results of the experiments are discussed, first in terms of the compounds that were transferred through the test paper samples and second in terms of the ability to use these methods to simulate transport processes.
There results of the individual experiments were combined and used to explain similarities and differences in the sample behaviour.
We show that the methods correlated well with one another and especially the polar compounds interacted strongly with the paper samples.
