Sweet, and flavorful peanut oil is organic edible oil obtained from pressing peanut kernels.Today, peanuts are widely cultivated as important oil seeds and a prime commercial crop in China, India, African nations, and the United States of America.
- Cold pressed peanut oil – This form of peanut oil is more nutritious and it contains the fatty acids in their original form. The peanut oil is generally filtered ( refined ), but for internal consumption, one should prefer the unfiltered one, which is difficult to procure.
- Roasted peanut oil – This comes from roasted peanuts. It has slightly different nutrient composition that the cold pressed oil because heat changes the nature of chemical bonds in the nutrients. This one has got a richer and more smell in it, so it is preferred in massage sessions.
- Iodized peanut oil – This oil is supplemented with iodine and is used in places where iodized salt is still not available or not produced.
Physical characteristics of peanut oil
- Peanut oil is high in energy; 100 g oil provides 884 calories.
- It is one of the cooking oils with a high smoke point; 450 °F. The property can be employed in setting oil temperatures while deep-frying food items.
- Peanut oil has very good lipid profile. It has saturated, monounsaturated and polyunsaturated (SFA: MUFA: PUFA= 18: 49: 33) fats in healthy proportions.
- It is one of the stable cooking oils; having a long shelf life.
Health benefits of Peanut oil
- Wonderfully pleasant, sweet-flavored peanut oil is low in saturated fats, free from cholesterol, contains essential fatty acid ( linoleic acid (omega-6)) making it as one of the healthiest cooking oils.
- It is a good source of plant sterols, especially β-sitosterol. The FDA has approved that, “Foods containing at least 0.4 gram per serving of plant sterols, eaten twice a day with meals for a daily total intake of at least 0.8 gram, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease.” Phyto-sterols competitively inhibit cholesterol absorption in the gut and thereby can reduce cholesterol levels by 10% to 15%.
- Peanut oil is high in calories. Its high-calorie value is because of fatty acids. The oil is especially rich in mono-unsaturated fatty acids (MUFA) like oleic acid (18:1) that helps to lower LDL or “bad cholesterol” and increases HDL or “good cholesterol” in the blood. Research studies suggest that Mediterranean diet that is enriched with monounsaturated fatty acids help to prevent coronary artery disease and strokes by favoring healthy blood lipid profile.
- Peanut oil contains resveratrol, a polyphenol antioxidant, which has been found to have protective function against cancers, heart disease, degenerative nerve disease, Alzheimer’s disease, and viral/fungal infections.
- Studies suggests that resveratrol cut stroke risk by alteration of molecular mechanisms in blood vessels and by increasing production of the vasodilator hormone, nitric oxide.
- Peanut oil contains valuable amounts of anti-oxidant vitamin E. 100 g fresh oil has 15.69 mg of alpha-tocopherol and 15.91 mg of gamma-tocopherol. Vitamin E is a powerful lipid soluble antioxidant, required for maintaining the integrity of cell membrane of mucus membranes and skin by protecting it from harmful oxygen-free radicals.
- In addition to being a vegetable source, peanut oil is also an ideal choice for deep-frying because it can be heated to a higher temperature (smoke point -450 °F). This results in lower oil retention in the fried foods
