      abstract     = {Recent European guidelines support the use of recycled and
                      biodegradable packaging for food applications. The approval
                      of such packaging must not alter food’s taste or be
                      harmful to health. In this work, PLA pellets were subjected
                      to a post-consumer contamination procedure, washing process,
                      and mechanical recycling, under common conditions of the
                      recycling industry. HS-SPME-GC-MS and HS-SPME-GC-O-MS
                      methods were used to detect volatile compounds and off-odor
                      profiles. 33 different volatile compounds were identified in
                      all samples. Intentionally added and non-intentionally added
                      substances (IAS and NIAS) were identified, including
                      benzaldehyde, benzyl alcohol, and
                      dimethyl-1,4-dioxane-2,5-dione. The relationship between the
                      formation of different NIAS and the PLA recycling process
                      steps was determined.14 different odor compounds such as
                      benzyl alcohol, benzaldehyde, nonanal, decanal, dodecanal,
                      2,3-dimethylnaphthaleneand 2,4-di-tert-butylphenol were
                      detected and classified into 4 aroma groups (Toasted,
                      Flower, Green and Chemical). The results obtained are
                      essential for the food safety of recycled plastic material
                      for food contact.},
