突然发现，这个帖子变得这么浮躁？其实冷榨油不少见啊， 如花生油，也可以是冷榨啊 - 坡县的话，除了橄榄油显示高档次， 芥花油比较实际，如果不怕掉价，米糠油还是健康的

Cold pressed oil is oil produced through a combination of grinding and low heat. Many types of fruits, seeds, and vegetables can be used to make it, but not all cooking oils go through this process. The introduction of heat to the process of making most oils degrades their flavor, nutritional value, and color, and may expose them to toxins. Regulations governing the cold pressing process are made often vary by country, so shoppers can benefit from reading all product labels before buying them.

Many people believe that cold pressed oil has a superior flavor
For 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.
