Cold-pressed oil is extracted from seeds, nuts, or fruits without using heat or chemicals. Instead, traditional wooden or modern mechanical presses apply slow pressure to release the oil.
Because no high heat is used, the oil retains its natural nutrients, aroma, flavor, and antioxidants, which are often lost in regular refined oils.

Pure mustard oil can be identified through its smell, taste, color, and texture. A genuine oil has a strong, pungent aroma and a slightly sharp, bitter taste, unlike adulterated versions that feel bland. Its natural color ranges from deep golden yellow to dark amber, and when kept in the refrigerator, pure mustard oil tends to thicken or solidify slightly due to natural fats. A simple palm rub test will also leave the distinct mustard smell lingering for a while, whereas impure oils lose aroma quickly. Even though home tests like the water float test can give an idea, the best way to ensure purity is to choose oil from a trusted source that offers cold-pressed, chemical-free, and lab-tested products.

Pure mustard oil, when unopened, can stay fresh for 9 to 12 months if stored in a cool, dark place away from heat and sunlight. Once the bottle is opened, it is best consumed within 6 months to enjoy its natural aroma, flavor, and nutritional value. For longer freshness, always store mustard oil in an airtight glass or steel container, keep it away from moisture, and use a clean, dry spoon while handling. If the oil develops a foul smell, cloudy texture, or bitter taste, it may have turned rancid and should not be consumed.
