What is the shelf life of cooking oils?
In a supermarket shop, there are many different types of oils to choose from, and each one has an expiration date. The following are some common food oils and their typical shelf life:
Coconut oil: Because of its taste and strong antioxidant content, coconut oil has become highly popular in recent years. Most varieties of coconut oil have a shelf life of roughly two years.
Olive oil: One of the most popular oils in the United States, olive oil is used to cook with when consumers desire a heart-healthy alternative to vegetable oil. This oil has a shelf life of two to three years. However, extra virgin olive oil has a shelf life of only one year.
Peanut oil: Despite its name, peanut oil has a neutral flavor, so if you use it to cook, your meal will not taste like peanuts. As long as it is sealed and unopened, a bottle of peanut oil will last a year. Once opened, the shelf life is reduced to 6 months.
Sesame oil: Many people believe that sesame oil should only be used after meals have been cooked. However, this regulation only applies to black sesame oil. Because light-colored sesame oil has the greatest smoke point, it may be used for frying.
While sealed and unopened, a bottle of sesame oil will survive for 2 years in the pantry but 3-4 years in the refrigerator. Once opened, a bottle of sesame oil will last for 6 months. However, if you keep the oil in the fridge after opening it, it will last for 9 months.
Avocado oil: Everyone likes avocados, so it’s no wonder that avocado oil is selling like hotcakes. The temperature of the environment has an impact on the quality of avocado oil and how long it lasts. Avocado oil will stay 9-12 months in your pantry, but 12-18 months in the refrigerator. You have 6 months to finish it after it is unlocked.
Vegetable oil: Vegetable oil is a traditional, all-purpose oil that may be used to fry a variety of dishes. It’s also used to deep fry battered meals like chicken nuggets and french fries. It makes no difference whether you store vegetable oil in the fridge or the cupboard. Vegetable oil has a shelf life of one year, regardless of whether it is opened or not.
However, there are methods to destroy new oil and render it rancid, and one of them is through improper cooking.
Common Errors That Cause Oil to Degrade
- Burning oil is one technique to transform perfectly useable oil into a rotten and awful oil that damages your meals and kills your stomach. Many people who do not cook at home have a tendency to burn their oil.
- Burnt oil occurs when the stove’s flame is left on for an extended period of time. Although five minutes is not a long time, anything on top of the flame will soon heat up. As a result, even the greatest grade oil may be readily destroyed in 5 minutes.
- Never cook something on high heat unless the recipe clearly asks for it. Warming your pan and oil on medium to low heat is quite OK.
- However, this is not the only technique to burn oil. Even if it’s at an acceptable temperature, many people become sidetracked and leave their stove to do something else. It should only take about a minute for the pan and oil to heat up.
- The oil and the pan will begin to smoke after 5 minutes of heating up with no food on top to begin the cooking process. If you notice the oil smoking, turn it off and let it cool.
- Cooking with smoky or burned oil is unhealthy and will wreck your digestive system. It is preferable to move the scorched oil to another pot to allow it to cool. After it has cooled slightly, resume cooking in the same pan you were planning to use.
- Once the oil has been burned, it cannot be recovered. So just get rid of it.
The third approach to burn cooking oil is to cook using non-frying or cooking oil. When it comes to oil grades, some are for dressings and are only applied to food after it has finished cooking, while others are for cooking.

Dressing oils are mild in flavor and light in texture. However, frying olive oil is thick and heavy. So, if you want to cook with it, make sure you get cooking oil. Cooking olive oil can also be used as a dressing; however, it will be considerably thicker.
How to Store Different Types of Cooking Oils
The temperature inside a pantry or cabinet should not be warmer than room temperature for keeping oil. Also, even if the rest of the home is heated, the pantry should not become hot. Make sure that none of the oils are ever exposed to sunlight, as the sun’s rays will swiftly damage the oil. Some oils are packaged in dark bottles to shield them from light.
Some oils have a longer shelf life when stored in the refrigerator. Avocado oil, certain grades of olive oil, fish oil, and walnut oil are examples of these oils. If you want to increase the shelf life of sesame oil, you can refrigerate it.
When you put oil in the refrigerator, there isn’t much you need to do. Just put them at the rear so they aren’t continuously exposed to warm air everytime the refrigerator door is opened.
Just keep in mind that not all oils can be stored in the fridge, and others are affected by cold air. So, for each oil, search for the words refrigerate after opening on the side of the bottle.
