Olive oil, due to its 11% polyunsaturated fatty acid content, exhibits greater oxidative degradation under heat compared to animal fats with <5% polyunsaturated fat content.
Olive oil from Al-Jouf stays fresher longer than olive oil from Pakistan when left out at room temperature, based on how quickly it breaks down.
Scientists can tell if olive oil is going bad by shining light on it and watching how the color changes — darker spots mean the good stuff is breaking down, and brighter spots mean bad stuff is forming.
The way olive oil is made and stored in different places might help it last longer, but we can't say for sure which part makes the difference.
