When it comes to proper storage, you should therefore pay particular attention to three factors: the temperature, the light and the influence of oxygen. Otherwise the oils will spoil.

Store oil: at the right temperature

In order to keep vegetable oils fresh for a long time, you should do so if possible cool to store. Good for those who have a wine cellar at their disposal.

Sunflower oil is also suitable for storage outside the refrigerator.

Storing oil in the dark is the key

In addition to the temperature, the effect of sunlight on the cooking oil is also decisive for its shelf life. Because meets UV light on the oil, this accelerates its aging. In addition, sunlight can have a negative effect on the contained ingredients such as vitamins and destroy them.
