Sesame oil is an edible vegetable oil derived from sesame seeds. The oil is one of the earliest-known crops-based oils. Historically, sesame was cultivated more than 5000 years ago as a drought-tolerant crop which was able to grow where other crops failed. Sesame seeds were one of the first crops processed for oil as well as one of the earliest condiments.
Sesame oil is one of the more stable natural oils but can still benefit from refrigeration and from limited exposure to light and high temperatures during extraction, processing, and storage; this minimizes nutrient loss through oxidation and rancidity. Storage in amber-colored or opaque bottles can help to minimize light exposure. Sesame oil made from seeds that have not been toasted is a pale-yellow liquid with a pleasant grain-like odor and somewhat nutty taste and is used as frying oil. Oil made from pressed and toasted sesame seeds is amber-colored and aromatic and is used as a flavoring agent in the final stages of cooking. Cold pressed sesame oil is unbleached, unrefined and cold-pressed which has a fresh aroma of sesame. For cooking and dietary purpose, cold-pressed sesame oil is one of the healthiest cooking oils with numerous health benefits.
