What has happened to this oil? I recently purchased some sun-dried tomatoes in oil. However a few days in the fridge and they look like this despite being unopened.



I regularly buy these tomatoes and store them in the same way. Can anyone suggest what might have happened?
Oil solidifies at cold temperature.

In the case of olive oil, it does so at 37F.

It takes a few minutes to get back to liquid state, either by leaving it on the counter or putting the jar in warm water.
