The oil that has gone rancid can emit an unpleasant aroma and taste, as well as potentially make you sick if consumed directly.
Vegetable oil can become rancid over time, too, but there are steps you can take to keep it fresh.

How Can Proper Storage Lengthen Vegetable Oil’s Shelf Life?

Vegetable oil will remain fresher for longer when kept at cool temperatures, particularly if exposed to long-term heat exposure.
Oil should generally be kept in a dark, cool location away from oxygen and light sources to extend its shelf life. Most cooking oils should be stored below 60 degrees F while more delicate varieties like truffle and almond oils should be refrigerated.
Some oils contain naturally occurring antioxidants and/or are enhanced with synthetic antioxidants to extend their shelf life and keep some from going rancid, especially when packaged and stored at cooler temperatures. Antioxidants may keep these oils fresher for longer.
Your cooking oils should always be stored in a container with an airtight lid to prevent air from getting inside and causing rancidity. Plastic containers should be periodically checked as soon as their tiny holes start clogging, allowing air to get inside.
One effective strategy for extending the shelf lives of oils is placing them in a colder, darker room like your basement. Temperature should be low enough to prevent oxidation – the main cause of rancidity – from occurring and thus increasing shelf lives.
Studies comparing the taste of olive oil stored in a freezer to that left out in a cupboard revealed that oil from the freezer tasted much less fishy and more clean.
Maintaining the optimal storage conditions for oil can prevent oxidation and peroxide formation that lead to rancidity in most oils, but this might not suit everyone. Before making your decision to store it in the freezer, test its flavor first to see what works for you.
If your vegetable oil has an unpleasant sour scent and musty flavor, it has likely gone bad. Mold around the seal may also indicate spoilage. Therefore, it is vital that you check the expiration date on its packaging to know when it should be consumed safely.

How does sunlight speed up vegetable oil spoilage?

Vegetable oil is an ideal cooking oil with numerous nutritional advantages, including being packed full of polyunsaturated. However, it is susceptible to spoilage if improper storage practices are followed, potentially turning rancid over time.
Storage away from direct sunlight is an effective way to preserve its quality for longer. Light accelerates chemical reactions which cause oxidation and degradation of oil molecules, altering their flavor, aroma, and appearance – potentially altering their taste, aroma, and appearance as a result.
Oil degradation occurs mainly when exposed to oxygen; it may also happen with exposure to temperature variations and moisture. To keep vegetable oil at optimal quality for longer, store it in a dark and dry location at room temperature in an airtight glass jar that doesn’t allow air leakage.
One way to increase the shelf life of vegetable oil is by purchasing it in tinted bottles or canisters, which filter out some of the sun’s rays and help it retain freshness and flavor for longer. Furthermore, heat can hasten its degradation so be mindful when keeping cooking oil outside the refrigerator!
Store oil in an opaque cupboard that’s out of direct sunlight and away from heat sources such as an oven or stove, especially if it will need to be warmed prior to baking.
Vegetable oil spoils for various reasons, with direct sunlight being one of the primary culprits. Placing it on the countertop or windowsill will expose it to air, which oxidizes it quickly and causes it to taste rancid – so it is best to store it in an opaque bottle or canister to avoid this scenario.
Heat is another key factor that can rapidly turn oil rancid. If storing it in an ambient temperature area is impossible, you could try placing it in the fridge but just be mindful to not open and close its lid too often.
Checking the label and cap for signs of damage is also recommended. If the vegetable oil smells musty, has an unpleasant bitter or sharp taste or there’s mold accumulating near its seal, this likely indicates it has gone bad and should be thrown away immediately.

To avoid vegetable oil from going rancid, it’s essential that it’s stored in a cool environment such as your pantry or fridge. Remember to seal tightly and store away from sources of heat such as your stove or oven.
As part of an effective food safety routine, it is a good idea to check your vegetable oil regularly in order to prevent it from going rancid and giving off unpleasant aromas or flavors. If your oil goes rancid it could even become rancid and give off unpleasant odors or tastes!
Oxidation is one of the main culprits behind oil spoilage. This process destroys its vitamin content while creating potentially toxic by-products.
In order to prevent this from happening, always opt for fresh vegetable oil that hasn’t been exposed to direct sunlight or other light sources. Furthermore, purchasing oils with antioxidants such as Vitamin E may help slow the oxidation process down further and prolong their shelf life.
Some types of vegetable oil, like extra-virgin olive oil, avocado oil and ghee are better at not going rancid than others. Coconut oil also offers medium-chain triglycerides which have great oxidation resistance properties.
Ideal, only use as much vegetable oil as needed over the next several days or a week. Any extra should be placed in the fridge until its usage becomes necessary again.
If you plan to use more than this amount of products, it would be prudent to store them in a glass container to save money and protect the contents from light and other sources that might ruin them. This way, they won’t become compromised due to sunlight exposure.
Darla DeMorrow, certified professional organizer and owner of HeartWork Organizing (opens in new tab), suggests keeping spices organized in separate jars when storing them to make it easier to spot expired or damaged spices so you can discard them before they create any problems.
An effective pantry organization strategy involves placing any extra items you have on top shelves so they won’t get forgotten and you can access them easily when necessary. This way, they won’t become disorganized in storage!

How Can You Tell If Your Vegetable Oil Has Gone Bad?

If you have an old bottle of vegetable oil that’s been sitting around, don’t forget to smell it first before opening it in order to ensure that you aren’t unknowingly consuming rancid oil that has yet to oxidize. Smelling will indicate any rancidity present that could lead to dangerously toxic consumption.
Sniff your oil carefully for signs of rancidity, such as a musty or pungent aroma. Additionally, the taste may become sour or bitter and it may even contain mold near its seal or cap.
Consider that most oils will eventually go rancid over time regardless of how or what you store or use them for. To reduce rancidity rates, store vegetable oils in dark, dry places away from light and air; or purchase high-quality oils packaged in opaque containers which have been known to keep oil fresher longer than standard glass ones.
However, you should consume all your vegetable oil within several months after opening it to prevent it from spoiling and going to waste. Small quantities should be used so as not to waste this precious resource.
Expired vegetable oil can be hazardous to your health, particularly if it contains hydrogenated fats or trans fats. Oxidative rancidity that forms when oils are exposed to heat and light can create oxidative stress in your body and increase your risk for degenerative diseases such as Alzheimer’s, cancer and heart disease.
Before discarding expired oil, it’s a wise idea to conduct a sniff test to assess whether or not it has become rancid – an essential consideration for anyone living with Parkinson’s disease or another olfactory loss condition.
Rancidity does not compromise the health benefits of vegetable oils like olive oil due to antioxidants found within them that protect from oxidative rancidity.
