Definizione

Process of extraction virgin olive oil by applying mechanical pressure to olive paste at a temperature of less than 25°C (IOOC). 1

Nota

The cold pressing of oil seeds does not need any pre-conditioning of the input material, which is pressed directly at room temperature. The oil temperature is low , and the acid value is also relatively low. As to the cold pressing,the oil produced by this methods are of great high quality. During cold extraction, ripe fruit or seeds are ground to a paste which is fed into a grinder. As 10 to 15 % of oil will remain in the press cake after milling, this procedure is quite expensive. It is only used for extracting oil from seeds with a very high oil content, such as olives and sunflowers. Cold pressed oils have a distinct flavor and intense color, whereas refined oils are lighter and usually clearer. 2

Contesto

The change is necessary in order to make it possible to market oil as cold-pressed. 3
