Does canola oil go bad? (+3 Nutritional facts)

In this brief introduction, we will address the question, “Does canola oil go bad?” as well as other questions pertaining to the subject at hand like how to store canola oil and how long it can last.

How Long Does Canola Oil Last

Canola oil lasts from 6 months to a year when opened.

Once you open the bottle, oil gets exposed to fresh oxygen which speeds up the oxidation process, resulting in the oil going rancid. However, that process is relatively slow, especially if you remember to keep the bottle sealed. After opening the bottle, you should finish it up within about 6 to 12 months for the best quality.

Like all other oils (peanut oil, sesame oil, rapeseed oil) canola oil also comes with a best-by on the label, which is a rough estimate of how long the oil should retain freshness.

Of course, the way oil is stored affects how well it keeps its quality. If you store the canola oil properly, it should last longer than the best–by date without going rancid. It can easily go rancid before that date if kept in the open, exposed to sunlight. The better the storage, the longer it should last in good quality past the date on the label.

3 Nutritional facts about canola oil

Contains Vitamins 

Canola oil contains vitamin E and K in a reasonable quantity. Vitamin K plays an important role in bone formation and blood clotting. It reduces the chances of serious injuries and excessive bleeding.

On the other hand, Vitamin E is a potential antioxidant that protects the body cells from the damaged caused by free radicals. Free radicals are harmful substances released during metabolism and are neutralized by adequate vitamin and mineral consumption. 

Both Vitamin E and K are fat soluble vitamins that can be stored in the body. So, adequate consumption of canola oil helps build up reserves in the body. 

Contains Omega-3 and 6 fatty acids

Canola oil contains Omega 3 and Omega 6 fatty acids that help to lower LDL Cholesterol and increase the HDL cholesterol. LDL cholesterol is bad for your health: conversely, HDL or “good” cholesterol positively influences one’s health. 

Best cooking oil

Despite being infamous for its overconsumption, canola oil has only 7% saturated fat, which makes it an ideal choice for sauteing and baking. The flavor of canola oil is also mild and does not interfere with the taste of other ingredients.

 

Summary

When stored well, canola oil can last for 1 year or more. What’s much more likely to happen

is that the oil goes rancid. Rancidity is caused by prolonged exposure to air, light, moisture,

or by bacterial action. Generally, rancid oil isn’t unsafe to consume, but it has that specific

rancid smell and taste. So if you notice that your oil is rancid, you can continue using it or

discard it.
