Flavor scalping, a food quality loss caused by packaging materials. The study investigated the volatile compoundsin food plastic packaging materials, green tea, and their interactions during storage. Staleness in green tea wascharacterized by increased alcohols, aldehydes, and ketones, with the severity varying based on the packagingmaterial. Polyethylene (PE), polyethylene terephthalate (PET), and aluminum-plastic composite (AP) packagingexhibited lower adsorption capacity for tea volatile compounds, contributing to the stability of these compoundsduring storage. Furthermore, nine off-odor volatile compounds were identified in seven types of packagingmaterials. Notably, migration of 2,4-di-tert-butylphenol, a compound with a leather-like odor found in higherconcentrations in polypropylene (PP) packaging, resulted in a decline in the sensory evaluation scores of thegreen tea infusion. Hence, the adsorption capacity and migration of odor compounds from packaging materialsare crucial factors for green tea flavor. These findings provide insights into flavor scalping in green tea.
