Hoy en d\u00eda el sistema de extracci\u00f3n de aceite de oliva m\u00e1s importante y eficiente es el de centrifugaci\u00f3n, combinado con el batido y una apropiada molienda. Hace unas d\u00e9cadas, el sistema tradicional eran las prensas o los molinos de empiedro. Pero si nos remontamos bastantes a\u00f1os m\u00e1s atr\u00e1s, encontramos una tremenda variedad de m\u00e9todos mucho menos eficientes que la actualidad. En este post os presentamos algunos de ellos.<\/p>\n

Pisado de aceitunas y torsi\u00f3n en saco.<\/strong><\/p>\n

Un m\u00e9todo usado hasta hace muy poco en la uva pero que tambi\u00e9n se usaba en la aceituna ya desde el antiguo Egipto. En un gran recipiente, pila o artesa o se colocaba un saco de gran tama\u00f1o de un material textil. Habitualmente lana de oveja o piel de cabra, donde se depositaban las aceitunas. \u00c9stas deb\u00edan estar muy maduras preferiblemente. Una vez hecho esto, se pisoteaba el saco, y luego se proced\u00eda a retorcerlo entre varias personas o usando barras de madera pas\u00e1ndolas por los extremos del saco para estrujar de una manera m\u00e1s potente. El aceite ca\u00eda por un agujero e iba a parar a una espuerta o recipiente colocado al efecto. Para optimizar el proceso y poder extraer m\u00e1s cantidad todo se regaba con agua caliente, se retorc\u00eda una y otra vez.\u00a0<\/p>\n

\"\"<\/p>\n

Aplastamiento mediante rodillo sobre una mesa de piedra. <\/strong><\/p>\n

Muy sencillo y usado en otros sectores. De hecho este procedimiento era muy similar al usado para los cereales. Lo ejecutaban las mujeres griegas que hac\u00edan rodar con un mecanismo de vaiv\u00e9n un rodillo de piedra sobre superficies tambi\u00e9n de piedra donde se depositaban las aceitunas. A la vez que se aplastaban, el zumo de la aceituna era recogido empapando masas de lana o tejidos. Estos textiles se estrujaban para extraer su contenido. Sol\u00eda hacerse con las manos y usando un recipiente. Para no desperdiciar nada lavaban los residuos en agua y recog\u00edan el aceite que quedaba en el l\u00edquido. .<\/p>\n

Trituraci\u00f3n manual con mortero.<\/strong><\/p>\n

Este sistema consist\u00eda en la trituraci\u00f3n del fruto en un mortero con un pil\u00f3n hasta obtener una pasta. Este pur\u00e9 se depositaba en una gran cuba o recipiente, generalmente de tierra cocida, sobre la que se vert\u00eda agua a alta temperatura. una vez hecho esto, se aplastaba repetidamente con las manos para liberar el aceite. Una vez que d\u00e1bamos tiempo, el aceite decantaba y quedaba en una capa que aparec\u00eda superficialmente y se recog\u00eda con las propias manos.\u00a0<\/p>\n
