Does canola oil go bad?
Canola oil does go bad after a year or two when unopened. After opening, you can expect up to 6 months of shelf life. Most canola oil bottles also come with an expiry date. Refrigerating the oil won’t extend its life much but can prevent it from going rancid as quickly.
Opening canola oil and exposing it to oxygen shortens the shelf life of the oil, but even then it can last up to a year in the pantry. Keep in mind that after opening a bottle of canola oil, it can be stored as a consumable for up to a year if kept in the pantry. You can use vegetable oil up to one year after the date printed on the bottle if it has been properly stored.
If your vegetable oil is not opened and stored properly, it should be stored for at least two years, if not longer.

If the smell is slightly sweet (like sticky paste) or has a fermented smell, then the oil is most likely rancid.

Finally, any sign of oil contamination is a sign that it is no longer usable. The main problem is rancidity, which occurs when oil molecules are oxidized when exposed to heat, air, or light. Unfrozen oil becomes anaerobic and leads to the growth of botulism, which can lead to botulism, a potentially fatal form of food poisoning. Rancid cooking oil produces harmful free radicals that cause long-term cellular damage and can lead to chronic disease.
Freezing the oil will change the structure somewhat, causing the oil to go rancid much faster after thawing. Freezing will not extend the shelf life in the slightest, and temperature fluctuations between freezer and ambient temperatures will actually cause the oil to go rancid very quickly. The freezing point of rapeseed oil is -10 degrees Celsius, however, this method of storage is not recommended, because, firstly, freezing will not extend the shelf life of rapeseed oil, and secondly, on the contrary, it will contribute to its earlier rancidity. If it so happens that you cannot provide the necessary storage conditions for rapeseed oil, it can be safely stored in the refrigerator, however, keep in mind that rapeseed oil will become slightly cloudy under the influence of cold.
Also, when buying canola, look for brands that sell products in dark glass bottles, as they protect the oil better than clear glass containers. Ditching clear bottles in favor of darker jars and bottles will mean less light will hit your oil, extending its lifespan. Some manufacturers bottle their oils in clear bottles, leaving the contents incredibly exposed to light. While those glass olive oil containers commonly seen on restaurant tables may look better than the bottle or jar your oil is sold in, if they are made of clear glass, they will not help prolong the oil’s shelf life.
Oils become sticky when they age and deteriorate; you should avoid buying sticky bottles and bags. Vegetable oil has a shelf life of 12 to 18 months and will usually retain quality for at least a couple of months after the date of printing.
Keep in mind that the oil most likely sat on a store shelf for a while before making it to the kitchen. Here you have to consider that the jar or bottle of oil has been stored for some time before purchase. You can also reuse the oil by carefully straining it through a colander and storing it in an airtight bottle, but be sure to separate it from the unused oil. Make sure it is away from your oven and other heat sources as temperature changes will seriously affect the quality of the oil.
Stored at room temperature, chili oil can be stored for at least 6 months, but the taste and pungency will gradually fade with storage. Because canola oil uses an element called hexane in the process of extracting the oil, this solvent creates trans fats when in contact with heat, destroys omega-3s, spoils food uneatable, and reduces food quality. Canola oil is good for heart health because it contains less saturated fat than other vegetable oils. If used oil is not properly filtered and stored after cooling, bacteria can feed on food particles left in the oil.
