As long as the oil is stored in an airtight container to prevent the absorption of freezer odors, its quality, including its polyphenol content and antioxidant properties, remains largely intact. In high-quality extra virgin olive oil, the wax content is generally low, which is why it remains clear at lower temperatures compared to lower-grade oils.
Does Freezing Affect the Polyphenols and Antioxidants in Olive Oil
Freezing Point Range Common State at -18°C Primary Cause of Solidification -6°C to -16°C Solid/Waxy Wax and Saturated Fat Crystallization Practical Storage Recommendations. Unlike water, which freezes at a consistent 0°C, olive oil undergoes a more complex transformation.
The best method is to transfer the sealed container to the refrigerator and allow it to thaw slowly over several hours or overnight. As the temperature drops, the oil begins to cloud and eventually forms a gel-like substance.
Does Freezing Affect the Polyphenols and Antioxidants in Olive Oil
When the oil cools slowly, these wax crystals have time to grow larger, scattering light and making the oil appear opaque. However, regardless of the crystal size, the presence of these solidified components is the definitive sign that the oil has moved outside its ideal liquid state for storage and use.
