Meat and Livestock Australia (MLA) commissioned The Odour Unit Pty Limited (TOU) to undertake a study to assess the degree to which an equivalence relationship can be formulated between an Electronic Nose (E-Nose), manufactured by -E-Nose Pty Limited, and measurements of odour concentration by dynamic olfactometry. This project focused on preparing and analysing a large number of synthetic rendering mixture and actual samples from the meat industry using both the ENose and dynamic olfactometry testing.

TOU developed a methodology to test a range of odour concentrations from tens to thousands of odour units to give a presentation of odours that may be experienced indoors or under downwind ambient conditions.
