The different densities of water and oil made the latter occupy the upper part of the tank.\r\n\r\nHowever, this system became outdated due to:\r\n<ul>\r\n \t<li>Hygienic-sanitary reasons, since current food regulations advised against the use of this system for obvious reasons.<\/li>\r\n \t<li>Economic reasons, since the yield was lower and the costs associated with its extraction made it extremely expensive.<\/li>\r\n<\/ul>\r\nThis system had drawbacks that made the olive oil often present some organoleptic defects.\r\n<ul>\r\n \t<li>The esparto mats were requiring scrupulous cleaning after each use, since the organic remains that could accumulate in them were fermenting by bacterial action and transmitting smells and flavours to the new oil.<\/li>\r\n \t<li>Contact with the ambient oxygen and with the water obtained from the decantation was initiating the oxidation process much earlier which, again, reducing oil\u2019s properties.<\/li>\r\n \t<li>This process was usually repeated two or three times, in order to obtain the maximum yield. This was making both the olive paste and the water start the fermentation process between each pressing, which was increasing oil degradation in each cycle.<\/li>\r\n<\/ul>\r\n<figure id=\"attachment_5975\" aria-describedby=\"caption-attachment-5975\" style=\"width: 1920px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-full wp-image-5975\" src=\"https:\/\/treurer.com\/wp-content\/uploads\/PrensadoFrio-Esteras.jpg\" alt=\"esteras para prensado en frio de aceite\" width=\"1920\" height=\"1280\" title=\"\" srcset=\"https:\/\/treurer.com\/wp-content\/uploads\/PrensadoFrio-Esteras.jpg 1920w, https:\/\/treurer.com\/wp-content\/uploads\/PrensadoFrio-Esteras-768x512.jpg 768w, https:\/\/treurer.com\/wp-content\/uploads\/PrensadoFrio-Esteras-1536x1024.jpg 1536w, https:\/\/treurer.com\/wp-content\/uploads\/PrensadoFrio-Esteras-300x200.jpg 300w, https:\/\/treurer.com\/wp-content\/uploads\/PrensadoFrio-Esteras-600x400.jpg 600w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><figcaption id=\"caption-attachment-5975\" class=\"wp-caption-text\">Oil cold pressing mats<\/figcaption><\/figure>\r\n<h3><span class=\"ez-toc-section\" id=\"Cold_extraction_the_current_method\"><\/span>Cold extraction, the current method<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\nThe use of more modern, clean and profitable extraction means has displaced the traditional system, which will remain as the oil\u2019s history.\r\n\r\nNowadays, we us centrifuge machines, which ensure the compliance of health regulations and help to produce an oil of the highest quality, free of impurities and oxidation processes as it\u2019s not in contact with air.\r\n\r\nThese centrifugal machines, also called decanters, use the density of each element present in the paste (oil, water, bone and skin) to proceed to its separation in a clean way, preserving all the oil\u2019s properties.\r\n\r\nThis centrifugation process is carried out in order to eliminate as much bone and skin particles \u2013 that can sneak into the process\u2013 \u00a0as possible.
