Food safety is an important concern in today's world. Providing a rapid, low-cost
system for meat quality assessment and monitoring would not only be a huge benefit
for public health and safety, but also for the environment by reducing wastage.
We developed an "electronic nose" composed of multiple metal-oxide semiconductor (MOS) gas
sensors to predict if the meat in excellent, good, acceptable or spoiled condition.
The meat standard from the Agricultural and Resource Management Council of Australia
and New Zealand was used in this experiment.
The beef was placed into a transparent acrylic casing with minimum airflow, similar
to what you will find in any fridge. The sensor array was placed on top of the
We can see that we have an excellent accuracy, predicting in each case the quality of
the meat, and using almost no RAM.
It shows this solution could be deployed cheaply in any appliance for a safer home or
