Regular commercial oils are made using heat and hexane (a powerful solvent) to extract the oil from seeds, plants, and sea life. The heat changes the nature of the oil molecule from a normal trans-fatty acid to an abnormal configuration. Molecules of hexane are left behind after the extraction process. In addition, there may be molecules of pesticides, herbicides, and fungicides from the growing process, if the plants were not organically grown!
The solution is to use cold-pressed oils, which are extracted using a high-pressure press (no heat and no hexane). When the plants are organically grown, there are also no chemicals, no pesticides and no genetic engineering. The pressing also occurs at much cooler temperatures.
At this point, the oils may be bottled or combined with other products to create margarine.
There’s no further processing, no additives, no preservatives, no caustic sodas, no bleaching, etc. Because of this, cold-pressed oils are very delicate and need to be handled with care to preserve their delicate flavors and high nutrition values. Always store cold-pressed oils in a cool dark place. Heat and sunlight will cause these oils to go rancid quickly. They will also transform the fats contained in the oil into trans-fatty acids.
Use cold-pressed oils in nearly all your recipes that call for oil. They are especially good on salads and other fresh food where the flavor and freshness of the oil is important. Most commercial oils come in a cold-pressed version. Do not use cold-pressed oils for high temperature frying or sautéing. These delicate oils do not work well at high temps.
Here’s a very basic salad recipe, with a simple vinaigrette. For a main dish, add 4 oz canned or grilled tuna or chicken, or 1/2 cup beans (such as cannellini beans or aduki beans).
