LECITHIN PRODUCTION

The starting products for the extraction of lecithin are mainly soya beans, rapeseeds and sunflower seeds. They are cleaned, dried and extracted. This produces a raw plant oil with a lecithin content of up to 2.5%. The raw oil is heated to a good 90°C with the addition of a small amount of water. Special separators then separate the lecithin from the raw oil. The wet lecithin broth is then dried and cooled to below 50°C in order to prevent it from darkening. The end result is liquid, native lecithin.

If powder or granulate are needed, the liquid lecithin's oil content is removed. This concentration process increases the functional proportion of lecithin, the acetone-insoluble proportion as it is known.
