Volatile compounds from packaging materials can migrate into packaged oats, influencing both flavour and safety. In the testing of six different oat brands, headspace sorptive extraction and comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC–TOF-MS) reveal how various packaging types—cardboard, paperƒ, and plastic—can affect and alter the oats’ volatile profile, underscoring the potential impact of packaging on food quality.
