Macadamia nuts are smooth and buttery to eat whole, so it’s no surprise that macadamia oil is popular for being a decadent cooking oil. What’s the best way to store this delicious oil to preserve its freshness?
The best way to store macadamia oil is in a cool, dark place away from direct sunlight and heat. Store macadamia oil in a tightly sealed opaque container to extend its shelf life.
You can refrigerate macadamia oil if you want to, but it has a longer shelf life than many nut oils so it’s not necessary.
Read on for more guidance on the best way to store macadamia oil!
What is macadamia oil?
Macadamia nuts are among the highest-fat nuts, so it’s no surprise that macadamia oil is often described as being “buttery”. This oil is ideal for roasting, baking, and deep-frying. Macadamia oil can also be used in salad dressing, as a butter substitute while baking, and as a skin moisturizer thanks to its high vitamin E content.
Macadamia oil is rich in monounsaturated fats, so it’s less likely to go rancid quickly compared to other oils that are high in polyunsaturated fats which are more prone to oxidation.
Another benefit of macadamia oil is its higher smoke point (around 410 degrees Fahrenheit), which is higher than olive oil. That means that macadamia oil is less likely to burn and create smoke when it’s heated at high temperatures.
What is the best way to store macadamia oil?
Macadamia oil should be stored similarly to other nut and seed oils – in a cool, dark place away from direct sunlight and heat sources. Specifically, here are some of the best ways to store macadamia oil:
- Store macadamia oil in a dark opaque bottle. This helps prevent light from damaging the fats, which can help prolong macadamia oil’s freshness.
- Make sure the bottle of macadamia nut oil is tightly sealed. This helps prevent oxygen from entering, which can cause the oil to go rancid more quickly.
- Make sure macadamia oil isn’t stored near any direct light sources (like next to a window) or heat sources, like the stovetop or oven.
- Store macadamia oil at a consistent temperature range, ideally within 40-85 degrees Fahrenheit.
- There’s no need to refrigerate macadamia oil, but it might not be a bad idea if you live in a particularly hot area. It can buy you a bit of time in terms of its shelf life, but always go by the use-by date for the most accurate guidance.
Factors that influence hazelnut oil storage
Temperature
Macadamia oil isn’t as “fragile” as some nut and seed oils, but keeping it away from extreme temperatures can help ensure it stays as fresh and high-quality as long as possible. Avoid storing macadamia oil in areas prone to extreme temperature fluctuations and consistently higher temperatures. A dark pantry or kitchen cupboard is the ideal storage location!
Method of extraction
Macadamia oil is typically cold-pressed or expeller-pressed. Cold-pressing yields the least amount of oil compared to other methods, but it’s considered ideal in terms of preserving the nutritional value. A downside of cold-pressing is that it can result in a shorter shelf life of the oils.
Expeller pressing exposes the macadamia nuts to a high amount of pressure, which creates heat as a byproduct. This heat can degrade the oil’s quality a bit and sometimes is coupled with the use of chemical solvents to further increase the yield amount of oil. This process usually increases the shelf life by making the fats more stable, though.
The best-by or use-by date on your macadamia oil might differ a bit depending on the method of extraction, so be sure to keep your eye on that date for the most accurate shelf life guidelines.
Signs that macadamia oil has spoiled
Be on the lookout for signs of spoiled macadamia oil such as:
- Having a foul odor: macadamia oil should have a pleasant scent, so if it’s anything but pleasant, it’s time to toss it!
- Macadamia oil has a subtle, nutty flavor. If it doesn’t taste pleasant (such as a chemical or bitter flavor), it might be past its prime, especially if coupled with a use-by date that’s in the past.
- Macadamia oil has a light golden/yellow color, so if it gets darker it can be a sign of the fats going rancid.
FAQs:
Macadamia oil has a long shelf life – up to one year at room temperature when opened and two years when sealed. Refrigerating the macadamia oil isn’t necessary because it has a high amount of antioxidants which help prevent spoilage, plus it’s primarily made of monounsaturated fats which are less prone to going bad.
Refrigerating the oil might extend its shelf life a bit, but it’s hard to say how much more time it would give you.
