POCATELLO, Idaho (AP) -- An Idaho State University chemistry professor and some of his students collected samples of extra virgin olive oil on a trip to Greece and now are working on a simple method to detect counterfeit oil.

John Kalivas tells the Idaho State Journal that extra virgin olive oil can be diluted with cheaper seed oils such as sunflower oil or corn oil, or mixed with cheaper olive oil.

So he's using information from test samples from extra virgin olive oil obtained in Greece to develop a mathematical model that can be used to determine purity.

Kalivas says the model will be adaptable for different instruments to make for quick and reliable testing.
