Cold-Pressed Flaxseed Oil: Alpha-Linolenic Acid (ALA) & Cold Preservation

The Golden Polyunsaturated Champion of the Fertile Crescent

True cold-pressed flaxseed oil is an astonishing biological substance: it contains the highest concentration of plant omega-3 fatty acids (Alpha-Linolenic Acid / ALA, 18:3n-3) found in any common terrestrial seed—routinely exceeding $55 - 60\%$ of total fatty acid content!

1. Alpha-Linolenic Acid Integration: Dietary ALA incorporates into endothelial and platelet cellular membrane phospholipids, competitively displacing arachidonic acid and shifting the eicosanoid balance toward anti-inflammatory Series-3 prostaglandins ($PGE3$) and Series-5 leukotrienes ($LTB5$).
2. The Fragility of Conjugated Double Bonds: Because ALA possesses three methylene-interrupted double bonds, it is extraordinarily sensitive to light, oxygen, and heat. Heating flaxseed oil above $45^\circ\text{C}$ causes rapid free radical chain peroxidations, generating noxious lipid peroxides.

The Master Cold-Storage & Culinary Protocol

• Storage Rules: Cold-pressed flaxseed oil must always be purchased in dark violet or amber glass, stored continuously in the refrigerator ($4^\circ\text{C}$), and consumed within 6 weeks of opening.
• Administration: Drizzle 1 to 2 teaspoons over cool salads, sheep's yogurt, or oatmeal. Never use flaxseed oil for frying, sautéing, or hot cooking.
