There are many different types of cooking oils in the market today, and it can be difficult to decide which one is the best for you. Two of the most popular oils are peanut oil and corn oil. Both have their own unique benefits and uses.
Both peanut and corn oils are extracted from the seed part only. Peanut oil has slightly more vitamin E than corn oil, but corn oil contains more magnesium, potassium, and zinc. Both oils are a good source of vitamin E, magnesium, and potassium, but corn oil is a better source of zinc.
In this article, we will discuss the benefits of both peanut oil and corn oil and how to use them. We will also help you decide which one is better for you!
Difference In Extraction Process Of Peanut And Corn Oil
Because peanut oil is processed differently, the final product varies depending on how it was made. Peanut oil can be either refined or unrefined.
Unrefined oils are extracted from peanuts by pressing them into cakes and crushing them to produce crude peanut oil. The production of refined edible oils takes one step further.
Once cold-pressed, the crude peanut oil is heated to very high temperatures (up to 450°F) and subjected to an additional filtering process that removes odor and color leaving behind a bland golden liquid.
The corn germ is obtained from the dried maize kernel through steam distillation or water extraction followed by partial separation of fatty acids via solvent extraction methods like hexane, chloroform, etc. Which also yield a higher corn oil from the germ.
The crude corn oil is then purified by degumming, neutralization, and bleaching processes to obtain refined corn oil.
- Degumming: The impurities are removed by treating it with phosphoric acid or citric acid followed by washing with water to remove the free fatty acids.
- Neutralization: After the refining process, free fatty acids are removed by adding caustic soda (sodium hydroxide). Fenugreek seeds can also be used in place of caustic soda but they give a bitter taste to the edible corn oil. Then further washed out with water for complete removal of soap formed from free fatty acids and alkali.
- Bleaching: After the neutralization process, a small quantity of bleaching earth is added to the oil and stirred well. This absorbs all color pigments and imparts a pale yellow appearance to the oil.
Both peanut oil and corn oil are extracted from plants, but they are processed differently. Peanut oil can be either refined or unrefined, while corn oil is always refined. The final product of each type of oil depends on how it was made.

Difference In Benefits Of Peanut And Corn Oil
Lower Cholesterol Levels
Peanut oil helps lower the levels of bad cholesterol in your blood. It does this by increasing the number of good cholesterol particles and decreasing the production of fatty acids.
This is also true for corn oil, which has been shown to reduce LDL (bad) cholesterol when used as a substitute for other oils that contain saturated or trans fat.
Good For Your Heart
Peanuts are rich in antioxidant compounds called polyphenols, especially resveratrol, which protect against free radicals and cardiovascular disease.
According to one study, eating two tablespoons per day of peanut oil for four weeks lowered the risk of heart disease in healthy women by up to 30 percent.
Both peanut and corn oils have anti-inflammatory effects, which is beneficial if you are struggling with conditions like arthritis or asthma. The omega-fatty acids found in these oils can help reduce inflammation throughout your body.
May Help Prevent Cancer
Some research has shown that the antioxidants present in peanut oil may help prevent some types of cancer, such as ovarian cancer.
These antioxidants work to neutralize free radicals, which can damage cells and lead to cancer development. Corn oil also contains antioxidants, so it likely has the same benefits.
Good For Your Skin
Peanut oil is often used in skincare products because it can help moisturize, soften and smooth your skin. This is due to its high vitamin E content, which acts as an antioxidant to protect your cells from free radical damage.
Corn oil has also been shown to improve symptoms of dry skin, including scaling and roughness.
May Help With Weight Loss
Peanut oil contains palmitic acid, a fatty acid that may promote weight loss by increasing fat burning in the body during exercise.
It’s important not to overdo this effect though; peanut oil is still very high in calories, so you still need to watch how much you use on a daily basis if you are trying to lose weight. Corn oil for weight loss is still controversial.

Use of Peanut Oil Vs Corn Oil
Both oils can be used in cooking, but peanut oil is better for high-heat cooking methods like frying because it has a higher smoke point. Corn oil is best used for lower-temperature methods, like baking or sautéing.
