Understanding oil based products - Cold Pressed vs Hot Pressed

Although from a glance oils might look similar, there are many layers behind an oil that gives it a characteristic. And even the most identical looking ones might have so many differences. There’s an oil for every purpose and a world of possibilities that could add make a difference on the oil. 

As oils can be separated by their source materials, they can also be differentiated by the method of extraction of the source material.  

In this article we are going to take a look at why we choose “cold pressed oil” in our production to make sure we provide best product options.

What is a cold pressed oil?  

The term “cold pressed” refers to how an oil is extracted from its source material. It’s usually done by a device that is called an “oil press”.  

With the cold pressed method, the source material that is going to be used for cold press can only be heated to a certain temperature. For it to be considered cold pressed, usually the extraction processes should be in the room temperatures. 

The reason behind using a lower temperature is to be able to preserve the natural compounds in the oil. By preventing a high acid value to occur, the need for further refinement is also eliminated. As a result, cold pressed oils can contain as much of their natural properties as possible.  

Cold pressing is also a traditional method to extract oil where by squeezing the seeds mechanically and without any additional heat being used. By not applying high temperatures, the natural character of oils can be preserved.  

Difference between hot pressed and cold pressed oil 

There are two ways of producing oil and although you may not be able to tell the difference by looking or tasting, finished products end up being completely different when they are cold pressed or hot pressed.  

Here are the differences between cold pressed and hot-pressed oils: 

- In cold pressing, the acid value is relatively low due to the low temperature applied and there is no need for any refinement. However hot pressing requires high temperatures which increases the acid value in the oil and this causes it to lose its natural quality.  

- By allowing the oil to retain its natural properties, cold pressed method keeps its original taste and purity. The high temperatures change the important substance of an oil such as vitamin e, sterols and carotenoids along with its taste. However, one positive side of hot-pressing method is that they provide a better smell for the oil. 

- Because hot pressed oils go through oxidization, it may cause complications and health problems due to the loss of healthy through hot pressing. Since cold pressed oils go through no refinement processes, they are a better choice in terms of health.  

In conclusion   

There are multiple reasons to choose cold pressed methods over hot pressed while creating natural oils and oil-based products. And for its clear benefits, at Greenliving Pharma, we always choose to produce our oil-based products using cold press methods
