peanut oil for deep frying

Peanut oil is a vegetable oil extracted from the seeds of the peanut plant (Arachis hypogaea), a legume native to South America. The oil is obtained through pressing or solvent extraction of shelled peanut kernels, yielding a pale yellow to golden liquid with a neutral to slightly nutty flavor depending on whether it is refined or unrefined. Refined peanut oil has a high smoke point (around 450°F/232°C), making it ideal for high-heat cooking applications, while unrefined "gourmet" peanut oil retains more peanut flavor but has a lower smoke point (around 350°F/176°C). The oil contains primarily oleic and linoleic fatty acids, contributing to its stability and extended shelf life compared to many other vegetable oils.

Peanut oil is widely employed in deep frying due to its high smoke point, neutral flavor, and ability to withstand repeated heating without degradation. It is particularly prevalent in Asian cuisines—especially Chinese, Thai, and Vietnamese cooking—where it serves as the primary medium for wok cooking, stir-frying, and deep-frying applications such as fried chicken, spring rolls, and tempura. Beyond frying, refined peanut oil is used in salad dressings, mayonnaise production, and general cooking. Unrefined peanut oil is preferred for finishing dishes, drizzling, and low-heat applications where peanut flavor enhancement is desired. Its clean taste profile makes it compatible with both savory and some sweet preparations.
