Abstract:

To study the characteristic odor components of express packaging bags, the volatile odor components of express packaging bags were obtained using a liquid?liquid extraction method, and then they were separated and identified by gas chromatography?mass spectrometry. The results indicated that there were 30 types of identified compounds, in which alcohols exhibited the highest relative mass fractions. The relative mass fractions of 2?(octadecyloxy)?ethanol, tributyl acetylcitrate, 1?chloro?heptacosane, 2?hexadecanol, 2?bromo?octadecanal, and tert?hexadecanethiol were also higher than other compounds. These odor components may play an important role in the special odor compositions of express packaging bags.

Key words: express bag, volatile odor component, liquid?liquid extraction, gas chromatography?mass spectrometry
