Modeling and experimental validation of mass transfer from carbonated beverages in polyethylene terephthalate bottles

► CFD can be used to qualify self life for carbonated beverages in polyethylene terephthalate. ► The carbonation level depends non-linearly on storage temperature and initial carbonation. ► The thickness distribution of polyethylene terephthalate can affect overall shelf life. ► The model can be employed in inexpensive trials of new designs “best used by” date assessment.
