Sesame oil is a popular ingredient in many cuisines around the world, known for its distinctive nutty flavor and aroma. But like any other cooking oil, sesame oil can go bad over time, especially if it is not stored properly.
How long does sesame oil last once opened?
If kept in a cool, dry place, I know I can get two – three months out of it — if it lasts that long. If you keep it on the counter exposed to normal kitchen heat and sunlight, it will go rancid quicker. I always smell my oils before use, it’s the best way I have found to detect is they’ve gone bad. The same with anything fatty kept in the cupboard like nuts.
The shelf life of sesame oil depends on several factors, including the quality of the oil, how it is stored, and whether it has been opened or not. Generally, unopened sesame oil can last for up to two years, while opened sesame oil should be used within six months to a year.
One of the main factors that can cause sesame oil to go bad is exposure to air and light. Oxygen and UV rays can cause the oil to oxidize, leading to a rancid taste and unpleasant odor. To extend the shelf life of sesame oil, it is important to store it in a cool, dark place, away from direct sunlight.
Another factor that can affect the longevity of sesame oil is moisture. Water can promote the growth of bacteria and mold, which can spoil the oil. It is essential to keep the container tightly sealed and avoid introducing any moisture into the oil.
In conclusion, while sesame oil does have a relatively long shelf life, it is important to store it properly to ensure its quality and flavor. By keeping it in a cool, dark place and tightly sealed, you can enjoy the nutty goodness of sesame oil for a longer period of time.
Does Sesame Oil Go Bad? Does It Keep?
Sesame oil is a flavorful and versatile oil that is commonly used in cooking and for its health benefits. However, like any other oil, sesame oil can go bad over time. It is important to store and handle sesame oil properly to ensure its freshness and prevent it from spoiling.
The shelf life of sesame oil can vary depending on various factors such as the quality of the oil, the storage conditions, and the presence of any additives.

In conclusion, sesame oil can go bad over time, especially when not stored properly. To ensure its freshness and prevent spoilage, store sesame oil in a cool, dark, and dry place, away from direct sunlight, heat, and moisture. Pay attention to its smell, color, and taste to determine if it has gone rancid. By following these guidelines, you can enjoy the full flavor and benefits of sesame oil in your cooking for an extended period.

This is because extra virgin sesame oil contains more natural impurities and antioxidants that can promote oxidation and spoilage.
3. Age of the oil: Sesame oil does not improve with age; in fact, it deteriorates over time. The fresher the oil, the longer its shelf life. It is advisable to check the production or expiration date on the bottle to determine the age of the oil. Using older sesame oil may result in a degraded flavor and aroma.
4. Contamination: Contaminants, such as water or food particles, can introduce bacteria or mold into the sesame oil, causing it to spoil more quickly. It is essential to ensure that the bottle and any utensils used with the oil are clean and dry to avoid contamination.
5. Usage and handling: How the sesame oil is used and handled can impact its shelf life.

However, like any other oil, sesame oil can go bad if not stored properly or used within a certain period of time. Here are some signs to look out for to determine if your sesame oil has spoiled:
1. Off smell: One of the first signs that sesame oil has gone bad is a rancid or unpleasant smell. Fresh sesame oil has a rich, nutty aroma, but if it smells sour, musty, or stale, it is likely spoiled and should not be used.
2. Change in color: Sesame oil should have a clear, golden color. If you notice any discoloration, such as a darkening or cloudiness, it could be a sign that the oil has gone bad. Discolored sesame oil should be discarded as it may indicate the presence of mold or bacteria.
3. Strange taste: Another indication of spoiled sesame oil is a bitter or sour taste. Fresh sesame oil has a smooth, mild flavor, so any unpleasant or off-putting taste is a clear sign that the oil is no longer good to use.
4. Sediment or particles: If you see any sediment or particles floating in the sesame oil, it is a sign of spoilage. Fresh sesame oil should be clear and free from any impurities. Sediment or particles could indicate the presence of contaminants or the breakdown of the oil.
5. Expiration date: It is important to check the expiration date on the sesame oil bottle. Like any food product, sesame oil has a shelf life, and using it beyond the expiration date can increase the risk of spoilage. If the oil is past its expiration date, it is best to discard it.
To prevent sesame oil from spoiling, it is crucial to store it properly. Keep it in a cool, dark place away from direct sunlight and heat sources.

Changes in Color and Texture
One of the key signs that sesame oil has gone bad is a change in its color and texture. Fresh sesame oil typically has a golden or amber color, with a smooth and clear texture. However, as it starts to deteriorate, the color may darken, becoming more brown or even black. This change in color can indicate the presence of impurities or oxidation, which can affect the quality and taste of the oil.
In addition to a change in color, the texture of sesame oil may also become thicker or more viscous over time. This can make it difficult to pour or use in cooking. If the oil has become thick and sticky, it is likely no longer suitable for consumption. It is important to note that these changes in color and texture can occur gradually over time, so it is always a good idea to check the appearance of the oil before using it.
To ensure that your sesame oil remains fresh for longer, it is recommended to store it in a cool, dark place away from direct sunlight and heat sources.

Rancid Smell
Sesame oil, like any other oil, can go bad over time. One of the signs that sesame oil has gone bad is a rancid smell. When sesame oil becomes rancid, it develops an unpleasant odor that is easily distinguishable. This odor is often described as a strong, sour, or off-putting smell.
The rancid smell in sesame oil is a result of oxidation, which occurs when the oil comes into contact with air. Over time, exposure to air, light, and heat can cause the oil to break down and become rancid. It is important to store sesame oil properly in a cool, dark place to prevent oxidation and extend its shelf life.
When using sesame oil, it is crucial to check for any signs of rancidity before using it in your recipes. If you notice a strong, unpleasant smell, it is best to discard the oil and get a fresh bottle. Using rancid sesame oil can greatly affect the taste and aroma of your dishes, and it may even lead to digestive issues.
To prevent sesame oil from going rancid quickly, it is recommended to use it within its recommended shelf life, which is usually printed on the bottle. Additionally, you can store the oil in the refrigerator to slow down the oxidation process and prolong its freshness. However, keep in mind that refrigerated sesame oil may solidify, but it will return to its liquid state once it reaches room temperature.
In conclusion, the rancid smell in sesame oil is a clear indication that it has gone bad. It is important to store sesame oil properly and use it within its recommended shelf life to avoid any unpleasant odors and maintain its quality. By being aware of the signs of rancidity and taking proper storage precautions, you can enjoy the full flavor and benefits of sesame oil in your cooking.
How to Store Sesame Oil
Sesame oil is a popular ingredient used in many cuisines around the world, known for its distinct nutty flavor and aroma. Whether you use it for cooking or as a finishing oil, proper storage is essential to maintain its freshness and flavor. Here are some tips on how to store sesame oil:
1. Keep it in a cool, dark place: Sesame oil is sensitive to heat and light, so it is best to store it in a cool, dark place, away from direct sunlight. Heat and light can cause the oil to oxidize and turn rancid more quickly.

FAQ
Does sesame oil go bad?
Phenols and other antioxidants naturally found in sesame oil slow this breakdown, and good storage can slow it even more, but the decay itself is inevitable. Eventually, the oil will become rancid: it will turn darker in color, develop a harsh aroma like paint thinner or nail polish remover, and start to taste unpleasant.
How do you keep sesame oil from rotting?
Heat and light are just as bad for your oil as air, so keep your sesame oil in a cool, dark place, like a closed cabinet away from the stove or refrigerator. And never refill a bottle that contains old oil with new sesame oil; even trace amounts of older oil will rapidly break down the fresh stuff.
Should you refrigerate sesame oil?
The short answer: It’s complicated. Must you refrigerate sesame oil? Absolutely not. It’s shelf-stable—for a time, at least—and it’s been a part of the human diet far longer than refrigeration has been around. (Sesame has been cultivated since the Bronze Age.)
How long does toasted sesame oil last?
Toasted sesame oil has a somewhat shorter shelf life, but you can easily extend it by storing the oil in the fridge. It’s important to note that the quality of toasted sesame oil matters more than plain sesame oil because it’s typically used as a finishing oil. If it tastes bad, it can ruin the entire dish.
