Rich in unsaturated fats, particularly monounsaturated oleic acid and polyunsaturated linoleic acid; contains vitamin E (tocopherols) and phytosterols with potential cholesterol-lowering properties.
About
Peanut oil is a vegetable oil extracted from the seeds (legumes) of the peanut plant (Arachis hypogaea), native to South America but now cultivated extensively in Africa, Asia, and North America. The oil is extracted through mechanical pressing or solvent extraction of dried, roasted peanut kernels. It ranges in color from pale golden to deep amber, depending on processing methods; roasted peanut oil has a more pronounced nutty flavor and darker hue than refined versions. Peanut oil has a neutral to slightly nutty taste profile and a relatively high smoke point (around 450°F/232°C for refined varieties, 325°F/163°C for unrefined), making it suitable for various cooking methods.
Refined peanut oil has minimal peanut flavor, while cold-pressed or roasted variants retain more pronounced nutty characteristics. The oil's composition is primarily unsaturated fats, with oleic and linoleic acids as major components, along with minor amounts of saturated palmitic acid.
Culinary Uses
Peanut oil serves as a versatile cooking medium across Asian, African, and American cuisines. Its neutral flavor and high smoke point make it ideal for stir-frying, deep-frying, and high-heat sautéing in Chinese, Thai, and Vietnamese cooking. Roasted peanut oil is valued for finishing dishes and drizzling over soups, noodles, and salads to impart subtle nutty notes. It is also used in dressings, marinades, and mayonnaise. In West African cuisine, peanut oil is fundamental to groundnut stews and peanut-based sauces. The oil's mild character makes it suitable for baking and as a carrier oil for infused aromatics.
