The use of SPME-GC/MS to determine the best packaging material for preventing light-induced off-flavors in milk

contributed by MilliporeSigma | 05/13/2020

Abstract

Light induced off-flavors (LIOFs) can be an issue when milk is packaged in high density polyethylene (HDPE) plastic jugs instead of glass bottles. In this study, we used solid-phase microextraction (SPME) followed by GC/MS to investigate the effectiveness of a range of plastic materials as barriers to the production of offflavors. Headspace SPME with a Carboxen^®/PDMS (CAR/PDMS) coated Nitinol fiber retains low molecular weight analytes which can be detected from samples at concentration levels of less than 1 ng/mL (ppb) allowing accurate analysis of these small flavoring analytes.
