Oil Filtration: Yes or No?

"Unfiltered oil is tastier"

This belief arises from the incorrect association of the concept of quality with processing techniques, considering the passage of oil from the filter as a denaturation phase of the product. In reality, the pasty and dense sensation you get when tasting an unfiltered extra virgin olive oil is not an intrinsic characteristic of the oil, however the result of the processing just performed. In fact, turbidity derives from the interaction between oil, water and olive paste. In fact, during extraction in the decanter, not all of the pasta and not all of the water are eliminated, but some of these remain in emulsion with the oil. Over time, due to the different density compared to olive oil, these compounds will tend to settle on the bottom. These are clearly not harmful substances for health, but their presence can cause any problems related to the conservation of extra virgin olive oil and its organoleptic characteristics. In fact, the taste of the vegetation waters or the rancid flavor of pomace is easily recognizable. Furthermore, due to the lack of oxygen, the substances deposited on the bottom will begin to ferment and produce compounds that will denature the oil. Filtration with special cartridges or with filtering sheets of different grades, allows to eliminate these suspended substances without altering the taste, aroma and organoleptic characteristics of the extra virgin olive oil.
