Expeller Pressed vs. Cold Pressed

All cold pressed oils are expeller pressed. But all expeller pressed oils are not necessarily cold pressed.

What is Expeller Pressing?
Expeller pressing is a chemical-free mechanical process that extracts oil from seeds and nuts. This method of oil extraction is an alternative to the hexane-extraction method used for many conventional oils and is usually used to achieve high production volumes and productivity. The temperature reached during pressing depends on the hardness of the nut or seed. The harder the nut or seed, the more pressure required to extract the oil, which in turn creates more friction and higher heat. There is no external heat applied during the expeller pressing

Cold Pressed?
Delicate oils, or those in which flavour or properties nuances are a key component, need to be treated with greater care in controlling processing factors.

Oils that are named cold pressed are in fact expeller pressed in a heat-controlled environment to keep temperatures below 120 degrees F. It’s important to note that, while Europe has rigorous standards in place for the terminology of cold pressing (fully unrefined oil extracted at temperatures below 122 degrees F), the phrase “cold pressed” has been used erroneously in the U.S. for a number of years, often employed as a marketing technique for oils which have been expeller pressed or even refined (which exposes the oil to temperatures of up to 470 degrees F).

Wira® Sacha Inchi Omega Oil is a “True Cold Pressed” oil  - First Cold Pressed Oil as some they call, manually and mechanically processed (no heat used at all) and filtered naturally without any chemical treatment or operation of refining. By following this process, we intend to preserve Sacha Inchi’s nutrients and benefits, as Mother Nature intended to.

Did you know that?

The pressing of nuts and seeds to extract their precious health sustaining oils, dates back thousands of years. The Egyptian civilization used oils for eating and cooking purposes and, of course, for body care, and so did the Roman, the Greek and the Incas.

Unrefined oils have always been the cornerstone of the old times peoples' diet. These oils were rich in nutrients and had particular individual taste, color, viscosity, and of course, unique aromas.

All of this was carefully sabotaged by the industrial oil refineries that reduced all oils to the bland, colorless and flat tasting clear oils that flood the marketplace: inferior oils that are detrimental to health.

However, in many places around the world, they have maintained traditional methods that produce high quality nutrient rich unrefined oils that have incredibly delicious flavour.

Since 1978, in France, it has been legislated that "virgin oils" must be obtained uniquely by mechanical means and filtered naturally without any chemical treatment or operation of refining. Good unrefined oils play a fundamental role in a balanced healthy diet.

Because there is no standard for "first cold pressed oils" in North America, it is easy for some manufacturers to literally "pull the wool over the consumer's eyes" by blending or cutting good quality oils with inferior ones and claiming that the oil is "cold pressed". As always: "beware".

General guidelines for buying good healthy oils:
  • 1. Always "first cold pressed" from a reliable producer, not a refinery.
  • 2. Certified Organic if possible.
  • 3. Always in dark ( green, brown or blue ) glass bottles. Never in clear glass bottles.
  • 4. Oils should taste delicious: fresh, clean, rich. Trust your taste.
