Description
Refined cold-pressed oil from the seeds of Linum usitatissimum (flax), distinguished by exceptionally high alpha-linolenic acid (omega-3) content of 50 to 60 percent, the highest among commercially significant edible oils.
Pale yellow to amber clear liquid with a characteristic nutty aroma. Refined food-grade material is distinct from industrial linseed oil used in paints and varnishes.
We supply food-grade Linseed Oil from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include food-grade cold-pressed virgin (for nutritional use), refined food-grade (for stability), industrial grade (for paint and varnish), and organic-certified material.
Bulk and reduced-MOQ shipments. Batch-level COA covering fatty-acid composition, acid value, peroxide value, heavy metals, and microbiology.
Introduction
Flax is one of the oldest cultivated crops, with both fiber (linen) and seed (linseed) traditions extending back over 5,000 years. The seed produces an oil with the highest alpha-linolenic acid content of any commercial oil at 50 to 60 percent.
The high polyunsaturated content drives both the nutritional value as a plant-based omega-3 source and the oxidation challenges that require cold storage and light protection. Food-grade linseed oil must be distinguished carefully from industrial grade, which often contains lead or other drier compounds incompatible with food use.
Canada is the largest producer of food-grade flax, followed by China and Russia. Heilongjiang and Inner Mongolia are the main Chinese growing regions.
The oil is heat-unstable and should not be cooked. Conversion of plant alpha-linolenic acid to long-chain EPA and DHA in the human body is limited (typically 5 to 10 percent), which is the principal nutritional limitation versus fish-derived omega-3 sources.
Where it is used
- Nutritional supplements for omega-3 fortification
- Vegan and plant-based omega-3 alternatives to fish oil
- Salad dressings and finishing oils (not suitable for cooking)
- Functional bars, shakes, and bowls in health-food channels
- Pet nutrition for omega-3 fortification, particularly canine
- Cosmetic carrier oil in skincare for dry-skin support
- Soap and bar manufacturing in artisanal segments
- Co-formulation in cardiovascular and brain-support supplements
