Flaxseed oil is extracted from the seeds of flax plants. It's rich in omega-3 fatty acids and lignans, which have various health benefits. The process of extracting flaxseed oil involves pressing the seeds to separate the oil from the solid residue. The pressed oil can then be refined or unrefined depending on desired properties like taste and stability.

1. Mechanical pressing: This method uses mechanical force to squeeze the oil out of the seeds.
2. Solvent extraction: In this process, solvents (like hexane) are used to extract the oil before it's separated from the remaining solids.
3. Cold pressing: This preserves more nutrients than solvent-extraction methods but may result in slightly less oil yield compared to mechanical pressing.

After extraction, the resulting oil needs to undergo refining processes such as degumming, deodorization, bleaching, and filtration to improve its taste, appearance, and storage stability.
