In this work, a range of different starch-based biopolymer samples, in the shape of pellets and retail samples (cups and dishes) were studied. The optimized extraction process was performed on three different pellet shapes: pellets with no modification (spherical), pellets shattered under high pressure (lentils), and pellets cryogenically ground (powder). The analysis of unknown volatile and semi-volatile compounds was carried out by gas chromatography-mass spectrometry, using both electron ionization with a single quadrupole mass analyzer (GC-EI-MS), and atmospheric pressure gas chromatography with a quadrupole/time of flight mass analyzer (APGC-Q/ToF). The identification process was implemented using the latest advances in the understanding of APGC ionization pathways. Chemical migration was also assessed on prototype samples using the food simulants: ethanol 10% v/v, acetic acid 3% w/V, ethanol 95% v/v, isooctane, and vegetable oil. Each migration test was performed three consecutive times, as recommended for materials intended for repeated use. 000079059 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FSE/T10$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/AGL2015-67362-P$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/RYC-2012-11856 000079059 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000079059 590__ $$a4.049$$b2019 000079059 591__ $$aCHEMISTRY, ANALYTICAL$$b14 / 86 = 0.163$$c2019$$dQ1$$eT1 000079059 591__ $$aBIOCHEMICAL RESEARCH METHODS$$b13 / 77 = 0.169$$c2019$$dQ1$$eT1 000079059 592__ $$a1.129$$b2019 000079059 593__ $$aAnalytical Chemistry$$c2019$$dQ1 000079059 593__ $$aOrganic Chemistry$$c2019$$dQ1 000079059 593__ $$aMedicine (miscellaneous)$$c2019$$dQ1 000079059 593__ $$aBiochemistry$$c2019$$dQ2 000079059 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000079059 700__ $$aDreolin, N. 000079059 700__ $$0(orcid)0000-0002-0759-9170$$aAznar, M.$$uUniversidad de Zaragoza 000079059 700__ $$0(orcid)0000-0003-2685-5739$$aNerín, C.$$uUniversidad de Zaragoza 000079059 700__ $$aHancock, P. 000079059 7102_ $$12009$$2750$$aUniversidad de Zaragoza$$bDpto.
