The Core Truth: All Soybean Oil Requires Processing
Whether organic or conventional, producing oil from soybeans requires a manufacturing process. The oil is naturally contained within the seeds, and to make it usable, it must be extracted and purified. The term "processed" is broad, and in the case of organic soybean oil, it is more accurate to distinguish between the methods used for extraction and refinement.
Mechanical Extraction: The Organic Standard
For organic certification, solvent extraction methods, which typically use chemicals like hexane, are prohibited. Instead, organic soybean oil relies on mechanical pressing, a method that uses high pressure to squeeze the oil from the soybeans. This can be done in two primary ways:
- Expeller-Pressed: The beans are heated and then put through a screw press that applies immense pressure. This generates friction and heat, which helps increase the oil yield.
- Cold-Pressed: A less common method for soybeans, cold pressing involves a screw press operating at lower temperatures (typically below 120°F). This preserves more of the oil's natural flavor and nutrients but results in a lower yield.
The Path to Refined Organic Soybean Oil
Even after mechanical pressing, the resulting "crude" oil contains impurities like phospholipids and free fatty acids. Most commercially available organic soybean oil is refined to remove these elements and create a more stable product with a higher smoke point. The refining process, which still must adhere to organic standards, can include several stages:
- Degumming: Water or a weak organic acid is mixed with the crude oil to remove gums and phospholipids.
- Neutralization (Optional for some processes): Impurities are removed using mild, food-grade solutions.
- Bleaching: Natural, activated clays are used to filter and remove remaining pigments, lightening the oil's color.
- Deodorization: The oil is heated under a vacuum with steam to remove volatile compounds that can affect taste and smell.
Understanding the "Minimally Processed" Label
Some organic brands market their products as "unrefined" or "minimally processed". This usually means the oil has only been filtered lightly to remove large particles and has not undergone the full refining process involving bleaching and deodorization. Unrefined organic oil will have a more pronounced flavor and a shorter shelf life compared to its refined counterpart.
Comparison of Soybean Oil Types
To illustrate the differences, consider this comparison table of organic and conventional soybean oil processing methods:
| Feature | Expeller-Pressed Organic Soybean Oil | Refined Organic Soybean Oil | Conventional Refined Soybean Oil |
|---|---|---|---|
| Extraction Method | Mechanical (Screw press) | Mechanical (Screw press) | Chemical (Hexane solvent) |
| Use of Solvents | No chemical solvents | No chemical solvents | Uses hexane solvent |
| Refining | Often unfiltered or lightly filtered (unrefined) | Degummed, bleached, and deodorized using organic-approved methods | Degummed, neutralized, bleached, and deodorized using conventional methods |
| Flavor Profile | Strong, distinct, beany flavor | Mild and neutral | Mild and neutral |
| Heat Stability | Lower smoke point, less suitable for high-heat cooking | Higher smoke point, suitable for high-heat cooking | High smoke point, ideal for frying |
Making an Informed Decision
When choosing an oil, it is important to understand that processing is not inherently bad. For organic soybean oil, the processing methods are restricted to ensure purity and avoid chemical contamination. The choice between a minimally processed, unrefined organic oil and a fully refined organic oil depends on your cooking needs and desired flavor profile.
For high-heat applications, a refined organic soybean oil is often the safer and more stable option. For dressings or low-heat sautéing, an unrefined version might be preferred for its robust flavor and higher nutrient content. Ultimately, the organic label ensures a cleaner, more sustainable production process from seed to bottle, regardless of the level of refining.

Conclusion
Yes, organic soybean oil is processed. The critical distinction lies in how it is processed. Instead of using chemical solvents like hexane, organic oil is extracted mechanically through pressing. While this is a form of processing, it adheres to strict organic standards that forbid the use of synthetic chemicals and GMOs. The level of refinement, from minimally processed to fully refined, dictates its flavor and cooking properties, but the organic certification guarantees a cleaner process from the start. Consumers can confidently choose organic soybean oil knowing the processing methods are carefully controlled and regulated.
