FLAVOR INVESTIGATOR: HAZELNUT

Hazelnuts however, are quite prevalent in are across the world in Italy and Turkey. Hazelnuts are nut of the hazel which derive from the species of genus Corylus.

One of the major flavour compounds found in hazelnuts is filbertone. Filbertone is naturally occurring ketone found in hazelnut oil. It has a roasted, fatty, sweet and long-lasting character. What is unique about this compound is that it can be used to test for the authenticity of olive oil. In order to adulterate olive oil some individuals add small amounts of cheap hazelnut oil to the olive oil. Therefore, if a sample is counterfeit one can use gas chromatography coupled with mass spectroscopy to test if filbertone.
If the compound is present than
the oil has been compromised. Besides that, Öz Star Machinery company provides many
other machines such as coffee Roaster, fryer, coating pans.
