Can vegetable oil go in the fridge?

In this brief article, we are going to answer the question “Can vegetable oil go in the fridge?”

Can vegetable oil go in the fridge?

Yes, vegetable oil can go in the fridge. There is no issue keeping oil in the refrigerator, but if you do, ensure that the container has a tight seal to prevent the oil from absorbing unpleasant refrigerator aromas.

Cooking oils containing polyunsaturated fats (PUFAs) should be kept in the refrigerator. Oils high in PUFAs, such as nut, seed, and fish oils, are particularly prone to oxidation. 

While many cooking oils become hazy when kept at low temperatures, keeping them at room temperature for a while should help restore them to their original form. Alternatively, store oils in a jar that can be scooped out before refrigerating.

Oils will oxidize if improperly handled or kept. Rancidity occurs when oil combines with oxygen, and apart from imparting an unpleasant flavor to dishes, oxidized oil does pose a health risk if consumed.

The higher the degree of unsaturation (double bonds) in oil, the greater its propensity to oxidize. Fish oil, for example, has four or five double bonds, making it very sensitive to spoiling. That explains why discarded fish has a distinct odor in the garbage.

Which cooking oils should be refrigerated?

Extra virgin olive oil

Olive oil has a larger monounsaturated fatty acid (MUFA) concentration than polyunsaturated fats, but less than saturated fats.

There are a few critical aspects to consider while keeping olive oil. Time, heat, oxygen, and light are the four primary enemies of cooking oil. Oxygen may cause the oil’s quality to degrade over time, resulting in rancidity, thus it’s critical to constantly seal the lid firmly when not in use.

If you consume it rapidly or reside in a colder location, you should avoid refrigerating it. However, if you purchase it in bulk or live in a warmer region, store the majority of your olive oil in the refrigerator and a little supply in a cold cupboard in a glass container for quick access.

Fish oil

Fish oil is a rich source of heart-healthy omega-3 and omega-6 fatty acids in an optimal ratio. Therefore, whether you get it in liquid or tablet form, it is essential to keep this one refrigerated.

Coconut Oil

Coconut oil should be stored in an airtight container in the coldest kitchen cabinet away from direct sunlight; ensure that the lid securely shuts. Coconut oil has a high concentration of saturated fat, which makes it relatively stable in comparison to other oils, and resists oxidation effectively.

While you may refrigerate coconut oil to extend its shelf life, doing so will alter its texture. It will solidify the coconut oil, which is perfect for no-bake applications but makes it more difficult to handle. All oils break down quickly when exposed to air or light. Store coconut oil in a dark, cool cabinet away from the light. This way, I can keep it fresh for longer.

Ensure that any rancid or damaged coconut oil is discarded. When analyzing your coconut oil, watch for a yellowish hue, irregular texture, and a nasty or unpleasant aroma.

Sesame seed oil

Sesame oil, which is often used to accent Asian foods, has 40% MUFAs and 42% PUFAs. Refrigerate this oil if possible.

Peanut Oil

Peanut oil, one of the most durable cooking oils, may be stored for up to two years if well-sealed and kept away from heat and light. While refrigerating peanut oil may prolong its shelf life even further, keep in mind that it may harden and become cloudy. At room temperature, it will begin to soften and clarify after about 30 minutes.

Oils of Canola and Corn

These culinary workhorses keep quite well in a cold, dark cupboard, or you may refrigerate them if a bottle lasts more than a year. Corn oil (and the majority of other oils) will become hazy when refrigerated. This is harmless, and the cloudiness will dissipate when the oil reaches room temperature.

How long is vegetable oil good for?

Vegetable oils come in a variety of varieties, including soybean oil, sunflower oil, and peanut oil. 

Their shelf lives, on the other hand, are relatively comparable. In general, if you don’t open or store your vegetable oil in the wrong way, it should last at least two years. Once the bottle is opened, the oil should be good for at least a year.

If you store vegetable oil properly, you may keep it fresh for an extended amount of time, even much longer.

Another thing to keep in mind is that oil’s flavor varies with time, and you may not like the changes if you want to use the oil in a salad. It develops rancidity.
