Oil Seeds are crushed to extract oil naturally in small batches. The natural process retains all nutrients and flavor

Cold Pressed oil simply means, oil extracted naturally by just pressing and not applying any external heat to extract oil.
The temperature of the oil during extraction is less than 40 degree. This temperature is little over room temperature because of the friction during the grinding/pressing process.

Because the temperature does not exceed 40 degree, all the essential nutrients and flavour are retained. Thus Cold Pressed oil is considered to be healthy.
