Many people believe that cold pressed oil has a superior flavorFor dressings and dishes in which the flavor of the oil will play an important role, it is generally superior to other cooking additives. When it is heated through cooking, consumers should be more concerned with the smoking point of the individual ingredient used, since some cold pressed oils can't handle high heat. These generally shouldn't be used in cooking anyway, since the delicate and complex flavor will disappear.
Possible Health Benefits
Cold pressed oil may be healthier than conventionally made oil because of the lack of heat and chemicals in the production process. In conventional extraction, raw materials are heated to very high temperatures, sometimes up to 450°F (around 230°C), which changes their chemical structure. They are also often made with chemicals like hexane, a solvent which can cause health problems
