2017/10/15 · A methodology was developed to measure volatile organic compounds (VOCs) in a non-destructive way inside modified atmosphere packaged (MAP) poultry (chicken fillets) samples stored at 4 °C. To achieve this, a solid-phase microextraction (SPME) fiber was inserted in the headspace of the package and was later desorbed within a heated injector coupled with a selected ion flow tube mass
