Olive Oil Filter
Olive oil is often filtered during the last step in its production process. The goal is to remove suspended solids and humidity, which give the oil a cloudy appearance that is less appealing to consumers. Suspended solids derived from the olive fruit, such as sugars, proteins and phospholipids may encourage hydrolysis and rancidity in the oil at later stages of storage (see Trends in Food Science & Technology 21 (2021):201). Thus, their removal by filtration may be desirable since it is known that after twelve months of storage, filtered oil mainly because of a slower rate of hydrolysis on the other hand, filtration also affects the color, sensorial and chemical attributes of the oil: fruitiness, pungency and bitterness may decrease with filtration, while rancidity defects may be more pronounced. Filtration may also compromise other positive attributes of the oil by reducing the levels of chemical constituents, such as polyphenols. There are trade offs in filtering olive oil that affect not only the product’s visual appeal, but also the intensity of its sensory attributes and potentially its shelf life. The goal of filtering should be water removal when it is present in large droplets, to avoid oil breakdown in storage.
