Mustard expeller oil is extracted from mustard seeds using a mechanical process known as expeller pressing. This method involves crushing the seeds with a screw press to extract the oil, without the use of heat or chemicals, preserving the natural flavor and nutritional qualities of the oil. The resulting oil is characterized by its golden yellow color and strong, pungent flavor, which adds a distinctive taste to culinary dishes. Mustard expeller oil is rich in monounsaturated and polyunsaturated fats, as well as omega-3 and omega-6 fatty acids, contributing to its nutritional value. It has a high smoke point, making it suitable for various cooking methods including frying, sautéing, and baking. Due to its robust flavor and beneficial fatty acid profile, mustard expeller oil is prized in both traditional and modern cuisines, particularly in regions where mustard seeds are cultivated.
