vegetable oil -
Vegetable oil is calorie-dense at approximately 120 calories per tablespoon and contains essential polyunsaturated and monounsaturated fatty acids. Most commercial varieties are cholesterol-free and may be fortified with vitamins A, D, or E depending on processing and regional regulations.
About
Vegetable oil is a lipid derived from plant sources, most commonly from seeds and beans including soybean, canola, sunflower, safflower, and cottonseed. These oils are extracted through mechanical pressing or chemical solvent extraction, then often refined through degumming, neutralization, bleaching, and deodorization to create a neutral-flavored, shelf-stable product.
Refined vegetable oils are typically light golden to clear in color, with a neutral taste profile and high smoke points ranging from 400–450°F (200–230°C), making them suitable for a wide variety of cooking applications. The fatty acid composition varies by source plant, but most commercial vegetable oils are predominantly composed of polyunsaturated and monounsaturated fats.
Culinary Uses
Vegetable oil serves as the foundation for countless cooking techniques including sautéing, frying, baking, and salad dressings. Its neutral flavor allows it to complement rather than dominate dishes, and its high smoke point makes it ideal for high-heat cooking methods such as stir-frying and deep-frying. Vegetable oil is also used in mayonnaise, vinaigrettes, and baked goods to provide moisture and tenderness. In professional and home kitchens worldwide, it remains the most economical and versatile cooking fat, with applications spanning from Asian wok cookery to European baking to American frying traditions.
