Difference between Cold Pressed Oil and Refined Oil

What is Cold Pressed Oil?

In cold pressing, oil is extracted at room temperature, or temperature less than 49°C (120°F), and the acid value is relatively low, so oil products are obtained after precipitation and filtration. This means that there is no need for any refinement.

Cold pressed oil retains most of its natural physiological and chemical properties and the nutritional value, aroma and flavour its original taste & Like a lot of important substances vitamin E, sterols, and carotenoids.


What is refined Oil?

On the other hand, refined oils are mass-processed using solvents and heat up to 250°C to extract more oil from the seeds. They contain trans fats but a reduced amount of nutrition. This is the term for the removal of most of the aromatics and undesirable constituents of oil distillates by liquid extraction. the oil from the initial process are bleached using bleaching clay, and deodorized, leaving the oil in its final state which is packaged and sold

Which is better for health?

From a health perspective, cold pressed oil is the clear winner. Refined oils undergo oxidisation, which can cause complications like cancer and inflammation. Moreover, a lot of healthy compounds are lost from the oils while refinement of oil, whereas in cold pressing, all beneficial compounds are retained. Another important factor that makes cold pressed oils a better choice is that it involves no refinement; unlike hot Refined oils which is refinement for improve the taste and acidic content.
