  Addressing odour abatement and assessment knowledge gaps using PTR–ToFMS quantity

  Add to cart

This report builds on previous odour research funded by AgriFutures Australia to find ways to assess and measure poultry odour more objectively, conveniently and cost-effectively.

It describes the use of state-of-the-art, high-resolution mass spectrometry (PTR–ToFMS) to determine the chemical composition of odour emissions from meat chicken sheds, and evaluate odour abatement strategies in terms of reductions in the compounds that contribute to odour impacts. This research provides deeper insight into the key odorants that abatement methods should be targeting and demonstrates the use of high-resolution mass spectra data for predicting odour concentration.

PTR–ToFMS has proven useful for characterising, assessing and quantifying meat chicken odours. A suite of compounds, including many known odorants, were reliably detected and measured in realtime. The report is targeted at researchers, producers, consultants and regulators concerned with the assessment of meat chicken odour nuisance, and the evaluation of odour abatement techniques. It provides evidence-based recommendations that will potentially enable future research and odour assessment to be performed more objectively, based on a better understanding of the complex chemistry and key compounds associated with meat chicken odour impacts.
