At Otelia Foods, we take pride in creating top-quality walnut oil that stands out for its nutritional value and versatility in the kitchen. A common question we receive is how our walnut oil can have a smoke point of 220°C (428°F) when most sources suggest that walnut oils have a lower smoke point of around 160-170°C (320-338°F). In this article, we’ll explain why our oil is different and how our unique process makes it perfect for high-heat cooking.
What is a Smoke Point and Why Does It Matter?
Let’s start with the basics: the smoke point is the temperature at which an oil starts to smoke and break down. When this happens, the oil loses its flavour, nutritional benefits, and can even produce harmful compounds. Smoke points vary based on how the oil is made and what it contains. Oils with more impurities tend to have lower smoke points, while cleaner oils can handle higher temperatures.
Comparing Otelia Walnut Oil to Other Oils
It’s important to consider how Otelia Walnut Oil compares to other popular cooking oils. For instance, extra virgin olive oil, while celebrated for its flavour and health benefits, has a smoke point of around 160-190°C (320-374°F). This makes it less suitable for high-heat cooking methods like frying or stir-frying. Similarly, other unrefined oils, such as flaxseed oil and sesame oil, also have lower smoke points, limiting their versatility in the kitchen.
In contrast, Otelia Walnut Oil’s smoke point of 220°C (428°F) makes it ideal for a wider range of cooking applications, including those requiring higher temperatures. This higher smoke point allows you to enjoy the nutritional benefits of walnut oil without worrying about it breaking down during cooking.
The Drawbacks of Heavily Refined Oils
Many cooking oils achieve higher smoke points through extensive refining, which involves using heat, chemicals, and bleaching to remove impurities. While this process does increase the oil’s smoke point, it can also strip away valuable nutrients, antioxidants, and flavour compounds, resulting in a product that is less nutritious and less flavourful. Some refined oils also contain trace amounts of the chemicals used in the refining process, which may raise health concerns
“Refined vegetable oils are incredibly unstable and oxidize easily when they are exposed to heat, chemicals, or light. These factors can lead to the development of trans fats and lipid peroxides. Trans fats may increase the risk of cardiovascular disease and type 2 diabetes, and lipid peroxide may disrupt your DNA, membrane lipids, and proteins. Both can increase the risk of chronic disease and lead to early signs of aging” —Integrative Medicine of Canada
Our Secret: A Special 5-Stage Filtration Process
What makes Otelia Walnut Oil different? It’s not just that we cold-press our walnuts—it’s what happens next. Our proprietary 5-stage filtration process gently removes impurities without heat or chemicals, helping the oil stay clean, neutral in flavor, and rich in natural nutrients. The result? A high smoke point of 220–240°C (428–464°F) and a smooth finish that works beautifully in any dish.
Here’s how it works:
-
Stainless Steel Mesh Filtration
First, the oil passes through a stainless steel mesh to catch larger particles right after pressing. -
Precipitation Filtration
We let gravity naturally separate out heavier solids—an extra-gentle step that protects the oil’s integrity. -
Plate and Frame Filter Press
Then, we filter the oil through a plate and frame system to remove fine solids while maintaining flavor and nutrition. -
Microporous Microfiltration
This precision step filters out microscopic impurities to ensure clarity and stability during cooking. -
Fine Filtration
Finally, a last pass through fine filtration polishes the oil—leaving it clean, light, and ready for high-heat cooking or everyday use.
The Role of Walnut Variety in Achieving a Higher Smoke Point
In addition to our proprietary 5-stage filtration process, the variety of walnut we select plays a significant role in the quality and performance of Otelia Walnut Oil. We carefully choose a specific variety known for its optimal balance of healthy fats and lower moisture content. This selection is crucial because walnuts with a more stable fat composition and fewer natural impurities tend to produce oil that can withstand higher temperatures without breaking down.
Our chosen variety is particularly rich in polyunsaturated and monounsaturated fats, which, when properly filtered, result in an oil that remains stable even at high temperatures. This variety, combined with our meticulous filtration process, allows us to achieve a smoke point of 220°C (428°F), making Otelia Walnut Oil ideal for all your cooking needs.
Certified Organic: Guaranteed Purity
At Otelia, we take our commitment to quality a step further by ensuring that our walnut oil meets the stringent standards of USDA Organic certification. This certification guarantees that our oil is produced without the use of synthetic pesticides, herbicides, or chemicals at any stage of the process—from the growing of the walnuts to the final extraction of the oil. You can trust that Otelia Walnut Oil is as pure as it is effective, providing a healthier option for your cooking needs.
The Result: A Better Walnut Oil for Cooking
Thanks to our carefully selected walnut variety, 5-stage process, and organic certification, Otelia Walnut Oil is purer and more stable than other walnut oils. This is why it has a higher smoke point, making it perfect for high-heat cooking like frying, stir-frying, and baking.
