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

enter image description here

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.

    not necessarily; it should be below 40F (fda.gov/consumers/consumer-updates/are-you-storing-food-safely)

  • In which case it looks like it’s too warm normally! Either way it’s the wrong temperature for this oil. Commented Nov 20, 2019 at 18:53
  • Temp and time required for olive oil to go solid varies from batch to batch. The stuff should liquefy again if you warm it gently. Commented Nov 20, 2019 at 23:13
  • @Max 40F or below

Had they been packaged in coconut oil it could look like that just by sitting in an air conditioned room as it solidifies at a steamy 70 degrees Fahrenheit.

    Have you ever seen tomatoes packed in coconut oil?
