Headspace Volatile Profile of Fresh-Cut Broccoli Raab in PET Packaging as Affected by Microperforation.

ABSTRACT: This work investigated the effect of high CO₂/low O₂ conditions in polyethylene terephthalate (PET) packaging on the quality of fresh-cut broccoli raab, focusing on volatile organic compounds (VOCs). Fresh broccoli raab was stored for 16 days at 5 °C in microperforated (MP) and in non-microperforated (NMP) PET packaging. During storage, the NMP atmosphere reached approximately 17% CO₂ and 0% O₂, while MP packaging maintained approximately 2% CO₂ and 19% O₂. NMP samples became unacceptable by day 7 due to loss of firmness and tissue deterioration, while MP samples remained acceptable until day 10, after which yellowing and shrivelling occurred. By day 10, MP VOCs were characterised by ß-caryophyllene, Z-3-hexen-1-ol acetate,
