E322 - Soy lecithin

E322, also known as lecithin, is a food additive that is often extracted from soy lecithin.

  • Function: Lecithin (E322) acts primarily as an emulsifier in foods. As an emulsifier, it helps stabilize mixtures of ingredients that do not mix naturally, such as oil and water. This allows for a consistent texture in many food products.
  • Source: Although lecithin can be extracted from different sources, soy lecithin is one of the most common sources. Soy lecithin is extracted from soybean oil and is rich in phospholipids.
  • Applications: Soy lecithin is used in a variety of food products, including chocolates, margarines, baked goods, pastas, sauces, dairy products and confectionery products. It is also used in the food industry for its emulsifying and stabilizing properties.
  • Emulsifying Properties: As an emulsifier, soy lecithin helps form and stabilize emulsions, which is crucial in many food preparations where immiscible ingredients must be mixed evenly.
  • Nutritional Properties: Soy lecithin contains phospholipids, which are beneficial lipid compounds. Phospholipids are also an essential constituent of cell membranes.
  • Alternatives: Although soy lecithin is widely used, there are other sources of lecithin, including sunflower lecithin. This may be relevant for those who wish to avoid soy products for reasons of allergy or personal preference.
  • Safety: Lecithin (E322) is generally considered safe when used in accordance with good manufacturing practices. It is widely accepted worldwide as a safe food additive.
