quick answer: what is the shelf life of cooking oil?
The shelf life of cooking oil depends on various factors, including the type of oil, storage conditions, and exposure to light and heat. Generally, unopened bottles of refined vegetable oils, such as canola, sunflower, or soybean oil, can last for about 12 to 24 months when stored in a cool, dark pantry. Once opened, these oils should be used within 6 to 9 months to maintain their freshness and quality. Unrefined or extra virgin oils, such as olive oil, have a shorter shelf life due to their higher content of antioxidants and polyphenols. Unopened bottles of extra virgin olive oil can last for about 18 to 24 months, while opened bottles should be consumed within 6 to 12 months. Specialty oils, such as walnut oil or flaxseed oil, have a shorter shelf life due to their higher content of unsaturated fats. They should be refrigerated and used within a few months after opening. Regardless of the type of oil, it’s important to store it in a cool, dark place, away from direct sunlight and heat sources, to preserve its quality and prevent rancidity.
how can you tell if cooking oil is bad?
Off-putting odor: Take a whiff of the oil. If it smells sour, rancid, or otherwise unpleasant, it’s time to toss it.
Change in color: Fresh oil should be clear or have a light golden color. If it has turned dark brown or black, it’s a sign that it’s gone bad.
Smoke point: Heat a small amount of oil in a pan over medium heat. If it starts to smoke before it reaches the desired cooking temperature, it’s a sign that it’s degraded and should be discarded.
Texture: Good oil should be smooth and pourable. If it has become thick, cloudy, or grainy, it’s a sign that it’s no longer fit for use.
Taste: If you’re unsure about the quality of your oil, take a small taste. If it tastes bitter, acrid, or otherwise off, it’s time to get rid of it.
Rancidity: Rancidity is a common sign of spoiled oil. It occurs when the fats in the oil break down and release free fatty acids. This can cause the oil to smell and taste bad.
how long can cooking oil be stored for?
Cooking oils can be stored for various lengths of time, depending on the type of oil, how it is stored, and whether it has been opened.

Olive oil can be stored for up to two years unopened, and for six months after opening. Unopened nut oils, such as walnut, almond, and hazelnut oil, can be stored for up to six months, and for three months after opening. Refrigeration can extend the shelf life of oils by a few months.
