Does avocado oil go rancid?

Avocado oil is fairly stable and doesn't easily go rancid. The reason why avocado oil has a stable shelf life is partly due to the low amount of poly-unsaturated fats. High amounts of poly-unsaturated fats form greater amounts of free radicals, which are associated with rancidity.

Does jojoba oil go rancid?

Plant oils readily oxidise or go rancid but jojoba is not oil. Its molecules have a structure that resists rancidity.

How do you keep canola oil from going rancid?

Canola oil should be stored in a cool, dark place in a tightly sealed container. It's important that the oil has minimal contact with light, heat or oxygen to slow the oxidation process, and so storing canola oil next to the stove is highly discouraged.
