Olive oil can form crystals and begin to turn solid if left in a refrigerator (which may also impact flavor). Your best bet is storing it in a pantry, away from light and oven heat.
Thus, if olive oil were pure triolein, it would solidify in a properly set refrigerator. However, olive oil is a complex mixture with significant variability in its fatty acid structure, and can be anywhere from 55% to 83% oleic acid, [17] [18] with the remainder a mixture of polyunsaturated fat and saturated fat, as well as containing waxes ...
An everyday example of cloud point can be seen in olive oil stored in cold weather. Olive oil begins to solidify (via liquid-solid phase separation) at around 4 °C, whereas winter temperatures in temperate countries can often be colder than 0 °C. In these conditions, olive oil begins to develop white, waxy clumps/spheres of solidified oil ...
"Avoid oils with strong flavors (e.g., olive oil) or low smoke points, as they degrade more quickly," says Poyourow. When possible, maintain a frying temperature between 350 and 375 degrees ...
Iyer explains that olive oil should be tightly sealed each time it is used to prevent oxidation. Oxidation can affect the oil’s flavor and speed up its aging toward rancidity. “Use olive oil ...

Add enough olive oil to cover the herbs, then freeze overnight. The next day, pop the cubes out of the tray and into a zip-top bag, then freeze for up to 1 year.
The most unsaturated oils are also called drying oils because they solidify in air, such as linseed oil. In this case it is not hydrogen but oxygen causes the saturation, although other chemical reactions, probably chemical condensation also occur. So linseed oil is a very good example for you LouisBB 07:20, 20 May 2006
