Paperboard contains several volatile organic compounds arising from both the naturally sourced materials and subsequent processing. Some of these compounds impart an odour to products. The traditional approach to quantifying odour uses a sensory panel, which is expensive and can be subject to problems brought about by fatigue. Selected ion flow tube mass spectrometry (SIFT-MS), however, can selectively detect and quantify a wide range of odour compounds in real time, more cost-effectively. This preliminary evaluation demonstrates SIFT-MS’s potential to provide odour ratings of paperboard samples. Measurements were coupled with multivariate statistical analysis to reduce the multi-compound dataset to a single parameter, the odour rating. The combined instrumental and statistical approach facilitated enhanced quality control through fast, economical screening of the widest range of volatiles.
