What does smoke point mean?

The definition of “smoke point” is the temperature at which the oil starts producing white visible smoke and stops shimmering. This is noticeable when cooking, as you can smell it and see smoke.

The situation indicates that the oil is breaking out, releasing toxic chemicals that may penetrate your food.

What happens when heat exceeds the smoke point?

You’ll know the oil has reached or exceeded the smoke point temperature when it starts to smoke intensely. This is normal if you’re cooking something in the wok, but that’s an exception.

When oil breaks down, it releases chemicals and free radicals that harm the human body. These chemicals are compounds known to cause cancer and other diseases.

Make sure to stay away from the smoke of overheated soybean oil and turn off the heat when the oil reaches the smoke point.

Besides making the food unhealthy, oil that’s broken down also gives out a burnt aroma and bitter flavor to food. If you let the oil smoke for a little longer, your food will quickly turn black and become ruined.

Also, if you cook with oil past its smoke point, any beneficial nutrients or phytochemicals are destroyed by the heat. So even a healthy refined oil becomes unhealthy and quite harmful to consume.

The bottom line is that the ideal condition for cooking with oil is when the oil hasn’t reached its smoke point yet.

A higher smoke point means we can use the oil for cooking in higher heat and for a longer duration.

So an oil with a high smoke point can be your best bet in the kitchen!

Why you need to consider the smoke point

Always consider the smoke point of an oil before you use it. The type of oil you should use depends on what type of food you’re making.

For example, you can’t use a low smoke point oil such as olive oil to fry french fries. The olive oil will burn and make the potato bitter and awful to eat.

On the other hand, if you’re making salad dressing, then soybean oil isn’t the best option. You should use this type of oil for baking, frying, and sauteeing.

Refined oils

Soybean is considered a refined oil. It’s usually refined for 3 applications and hydrogenated.

And did you know that refined oil has a higher smoke point? This is because during the refining process, free fatty acids and impurities are removed. The impurities cause the oil to smoke.

In addition, soybean oil is a low-allergen food, so it can be consumed by most people.

The smoke point of soybean oil

The smoke point of soybean oil is at 234-256°C, which is equal to about 453-493°F.

If you compare these numbers to other cooking oils, you might find them rather high. This makes it excellent for baking and deep-frying.

Even so, soybean oil isn’t the oil with the highest smoke point.

Here are the smoke points of other oils commonly used for cooking:

  • Butter: 150°C
  • Extra virgin olive oil:163-190°C
  • Virgin coconut oil: 190°C
  • Lard: 190°C
  • Canola oil: 204°C
  • Cottonseed oil: 216°C
  • Sunflower oil: 232°C
  • Soybean oil: 234°C
  • Rice bran oil: 254°C
  • Refined avocado oil: 270°C

You may have noticed on the list that solid fats tend to have lower smoke points than liquid oils.

That is because solid fats usually contain more free fatty acids (FFA), which are very easy to break down.

Soybean oil for cooking

You don’t necessarily have to use the oil with the highest smoke point to cook. What’s important is to know the temperature of a cooking method you’re about to do and make sure you choose the oil that can withstand the temperature. You can choose the oil that you prefer taste-wise.

For example, here are some of the cooking methods and the temperatures they may hit:

  • Confit: 93°C
  • Pan-fry: 120°C
  • Sauté: 120°C
  • Deep-fry: 120-180°C
  • Pan-sear: 204-232°C

Soybean oil’s smoke point is much higher than the regular cooking temperature. So you can use it for any cooking method without worrying that it might break down before your food is well done.

However, you might need to pay attention while cooking, especially if you let the stove stay on for a bit longer. The temperature may gradually rise and eventually, smoke will start to form.

To avoid this, you can lower the heat when you feel like your stove’s getting hotter.

Can you use soybean oil for deep-frying?

Many people love deep-fried foods and use a deep-frier to make delicious dishes such as french fries, potato wedges, or deep-fried chicken drumsticks. In this case, you’re probably wondering if you can use soybean oil to deep-fry food.

Soybean oil is cheap, especially when bought in bulk. So yes, you can use soybean oil to deep fry your favorite foods!
