Cold-pressed oils have enjoyed great popularity for years among people who value health, nutrition, and a natural lifestyle. They owe their exceptional health-promoting properties to the low-temperature pressing process, which preserves a maximum of vitamins, fatty acids, and antioxidants.

But there is also a downside: Cold-pressed oils are extremely perishable. If stored improperly, they lose their properties, change their taste, and can be harmful to health. That's why it's so important to know the proper handling of these natural treasures.

cold-pressed oils require special care?

Refined oils are heat-resistant and can be stored in the kitchen cabinet for months. Cold-pressed oils, on the other hand, belong to a completely different category – they are neither refined nor artificially stabilized.

What destroys them?

• Sunlight – UV rays accelerate the oxidation process.
• Oxygen – Contact with air causes rancidity.
• Temperatures (above 20 °C) destroy sensitive fatty acids, especially omega-3.
• Moisture and impurities – can affect the taste and accelerate spoilage.

In short: Cold-pressed oils tolerate neither heat nor light and no long storage.

General rules for storing cold-pressed oils

1. Refrigeration is the best choice.
   Most cold-pressed oils are best stored at 4–10 °C.
2. Dark glass protects from light
   . The bottle should be made of dark glass. Plastic and clear glass are not good choices.
3. A tight seal is essential.
   Even a few hours of open oil accelerates its oxidation.
4. Buy small bottles.
   It's better to buy 250 ml and consume it within a month than a liter that spoils.
5. Always read the label.
   The manufacturer specifies optimal storage conditions and the time after opening.

The influence of storage on nutritional value

Improperly stored oil:

• loses vitamin E (a powerful antioxidant),
• reduces the content of omega-3 fatty acids,
• becomes a source of free radicals that harm health rather than promote it.

Therefore, the freshness of cold-pressed oil is not only a matter of taste but also of health.
