For some oils, the process of extraction is fairly straightforward. Take Chia Seed Oil for example, a simple mechanical press is sufficient to extract the oil from the seed without any additional processing. This process is known as cold pressing.
However, most oils on the market are extracted using a combination of pressing, cooking, solvent extraction and centrifuge pressing.
At Erbology, we cold-press all of our oils and only our Organic Sea Buckthorn Berry Oil is centrifuged to preserve its nutritional properties.
