Product Reviews, Blog

YouTube video

A mildly flavored oil, peanut oils is excellent for frying…

…and is frequently used in Asian cuisines.

Most major grocery stores carry peanut oils in several varieties…

While the wok can be used for a variety of cooking methods..

…it is primarily used for stir-frying. You can’t stir fry properly…

…unless you crank up the heat. Cooking at high temperatures requires oil..

…with a high smoking point. In other words, you should always stir fry…

…in oil that has a high smoke point.

Let’s hear Amira’s story…

I’m trying to make Asian cuisine, a vegetable stir-fry…

But I don’t understand why the smoke gone wild…

The smoke shouldn’t be this much. Seems like I’m using the wrong oil...

Peanut oil is rich in vitamin E, an antioxidant that offers many protective benefits against chronic disease.

Let’s talk about the basic first…


Basic of Stir-frying Oils

Fried food is usually fried at 350 degrees Fahrenheit…

450F is the minimum temperature for stir frying. It can go higher..

…but that’s the minimum. If you stir fry with oil that has a smoking point…

…below 450F, not only will your food taste bad…

…but it will also be hazardous to your health.

Smoking oil already poses a health risk, isn’t it?

Actually, no. It allows the oil to heat up to the point where bluish smoke appears…

…which can be dangerous. The smoke can sting your eyes at that point…

…and the oil in the pan can catch fire. Stir-frying involves heating up…

…the oil until you see fine wisps of white smoke…

…hovering above the surface of the wok.

So, which cooking oils have a smoking point of 450F and higher?

Peanut oil (refined) – 450F

Safflower oil (refined) – 510F

Corn oil (refined) – 450F

Soybean oil (refined) – 450F

Ghee (clarified butter) – 450F

What’s up with the “refined” in parentheses?

Virginity can be compared to this. Unrefined oils are virgin oils…

In Chinese stir frying, peanut oil is the default cooking oil…

…but it is not just any peanut oil. It is refined peanut oil.

Peanut oil has a smoking point of 320F when unrefined…

In refinement, a variety of processes are used to filter out…

..compounds that burn quickly. With ghee, for instance…

…the butter is heated until the milk solids separate from the fat.

The browned milk solids sink to the bottom of the pan leaving…

…the fat free to be poured into a container.

Here we go…

…but excessive amounts can be harmful. Peanut oisl can be used in conjunction..

…with some omega-3-rich oils, like olive oil.

According to the Food & Drug Administration (FDA)..

…people with peanut allergies do not need to avoid peanut oil.

When peanuts are refined into oil, the proteins that cause…

…allergic reactions are removed. This is not the case for cold-pressed peanut oil…

…so people with peanut allergies should avoid this type of oil.

…sauces, and marinades.


Peanut Oil Blends

…to make them more affordable. It is usually blended with an oil…

…that has a similar high smoking point to preserve its excellent frying properties.

Let’s move one…


Allergies to Peanut Oil

Peanut oil that has not been refined or peanut oil that has been roasted..

…may cause an allergic reaction. “Refined” peanut oils, which include…

…the varieties most often used in food service operations…
