The Winter Solidification Test

One of the most reliable characteristics of pure coconut oil is its reaction to temperature. Because natural coconut oil is rich in healthy saturated fats, it has a high freezing point (around 24°C or 76°F).

* The Pure Sign: During cooler months or when placed in the refrigerator, 100% pure coconut oil will solidify completely, turning into a stark white, butter-like consistency.
* The Adulteration Red Flag: If the oil remains a liquid in the fridge or only partially solidifies (creating a patchy, separated look), it has likely been cut with cheaper, low-grade liquid oils.
