Cold-Pressed vs. Hot-Pressed Black Seed Oil: What is the Difference?

When you buy black seed oil, you usually see it advertised as a cold-pressed oil. That is what you want, but we get a lot of questions about hot press and why we use cold press techniques to make our black seed oil. So, let us put the questions to rest and look at cold-pressed vs. hot-pressed black seed oil and why the difference matters:

What is Cold-Pressed vs. Hot-Pressed?

Cold press vs. hot press refers to the process in which the oil is extracted from the seeds. 

 

In a cold-press process, the seeds are not heated during the extraction. With a hot press process, the seeds are heated during extraction. In cold-pressed all the minerals and nutrients are preserved in full. 

 

Hot-press has several benefits over cold-press from a manufacturing standpoint: the seeds move through the machine faster, which means more oil is being extracted from the seed, and there is no pressure on the equipment. The quality of the black cumin oil is poorly because the main components and minerals are burned during hot-press production. 

Are All Black Seed Oils Cold-Pressed?

A lot of black seed oils identify as cold-pressed, but here is what is really happening. Cold-pressed techniques are not as “cold” as you might think. Black seed oil extraction requires the coming oil from the Nigella Sativa seeds to be below 114℉, or +45℃. This is considered cold-pressed, even though it is pretty hot to the touch.

If you go back to our previous blog post that looks at the pressing machines worldwide, you will recall that these machines are pressing huge quantities of seeds at a time. The machine itself raises the temperature during the extraction process – there is no way around it unless you try to defy the law of physical science.

It is the equivalent of rubbing your hands together fast on a cold day. It is cold outside, your hands are cold, but they get warmer as you rub them together. That is basically what is happening inside the machine. The faster the machine works, the more heat it produces.

What Makes BioNatal Unique?

 

BioNatal uses small commercial machines that squeeze the seeds slowly and can maintain the temperature we want. It is like being able to control how fast we rub our hands together on a cold day.

This allows us to produce authentic cold-pressed black seed oil. It is room temperature (77-98℉) instead of 114℉ or +45℃.

 

We also check the temperature of our oil differently. Rather than recording the temperature of the oil as it is expelled from the machine, we record temperatures of the oil inside of the machines the moment it is pressed. This eliminates any chance for the oil to have cooled once it exits the machine to get the most accurate reading.

 

We also work our machines for just three hours at a time to mitigate temperature increases. 

 

We also take care to reduce our benzo(a)pyrene levels as much as possible. The international allowable amount of benzo is 2.00, but ours is just 0.95 that you can see on the Certificates page. There are no regulations in the U.S. for benzo(a)pyrene levels unless it is water, but oils often enter the country with benzo(a)pyrene levels as high as 10.00 or more! Benzo(a)pyrene has been shown to produce a multitude of negative health effects, and the temperature of the oil during production has a lot to do with benzo(a)pyrene content.
