Nutritional Integrity and Flavor Profile Because expeller pressing avoids harsh chemicals, the resulting oil often retains a more robust, authentic taste compared to its refined counterparts. However, even with this temperature increase, the process remains fundamentally mechanical.
How Expeller Pressed Oil Connects to Source Materials and Extraction Methods
For example, expeller pressed high-oleic sunflower oil has a high smoke point suitable for sautéing, while expeller pressed extra virgin olive oil is ideal for low-and-slow cooking. Some producers address this by cooling the raw materials before pressing or by incorporating a separate cooling stage post-extraction to preserve delicate flavors and nutrients.
The smoke point is determined by the specific type of fatty acids present in the oil itself, not the extraction method. This inherent heat can cause the temperature inside the press to rise, sometimes reaching levels that exceed the threshold typically defined as "cold" (under 120°F or 49°C).
How Expeller Pressed Oil Source Impacts Nutrition and Flavor
Temperature Considerations While the term "cold pressed" is often associated with expeller pressing, it is important to note that friction generates heat. As raw material, such as sunflower seeds or olives, is fed into the press, the screw forces it forward.
