Argan oil is typically processed through a method that involves extraction from the kernels of the argan tree fruit. While some traditional methods might involve boiling, which can degrade valuable nutrients, a preferred method focuses on preserving the oil's quality through careful steps.
According to the provided reference, unlike many traditional nut oils that are boiled (a process that can destroy valuable nutrients), cold pressing is a key method used, specifically mentioned in the context of "Silk Oil of Morocco". This approach emphasizes:
- Organic Growing: The argan fruit is sourced from organically grown trees.
- Hand Selection: The nuts or kernels are carefully selected by hand.
- Cold Pressing: This is the primary extraction method mentioned. Cold pressing involves mechanically pressing the argan kernels at low temperatures. This method helps preserve the oil's nutritional profile, including fatty acids, vitamins, and antioxidants, which might otherwise be lost through heat exposure like boiling.
This highlights that the processing of argan oil varies, with methods like boiling being less ideal for retaining nutrients compared to techniques like cold pressing, which is favored for producing high-quality oils that maintain their natural benefits.
Traditional vs. Modern Processing
| Method | Heat Involved? | Nutrient Retention | Common Use Case |
|---|---|---|---|
| Boiling | High | Lower | Traditional methods (less common for high-quality oil) |
| Cold Pressing | Low | Higher | Producing high-quality, nutrient-rich oil |
Cold pressing is widely regarded as the superior method for producing argan oil intended for cosmetic or culinary use where preserving its beneficial compounds is crucial.
