Soybean lecithin to 2028: types, uses, sourcing and stability in food processing

Soy lecithin is one of the most common emulsifiers in food. Its grades, non-GM sourcing, allergen labelling and storage behaviour all affect how manufacturers use it.

Soybean lecithin is one of the most widely used food ingredients that consumers rarely think about. It helps chocolate flow, keeps margarine and spreads stable, improves dough handling, helps powders dissolve and acts as a release agent. The original report on this page covered the soybean lecithin industry by material type, product type and region with a forecast to 2028. This update explains what the material is, how it is made and used, and what manufacturers should know about sourcing and storage.

What lecithin is

Lecithin is a mixture of phospholipids, such as phosphatidylcholine, phosphatidylethanolamine and phosphatidylinositol, along with oil and other components. Phospholipids have one end that attracts water and one that attracts fat, so they work as emulsifiers, helping oil and water mix.

Soybean lecithin is produced during the refining of crude soybean oil. In the degumming step, water is added to the oil, the phospholipids hydrate and form gums, and these are separated and dried to make lecithin. Other sources include sunflower, rapeseed (canola) and egg yolk.

Main product types

  • Fluid lecithin, a viscous liquid containing phospholipids and oil. It is the most common and least processed form.
  • De-oiled lecithin, powder or granules with most of the oil removed. It is easier to handle and dose and is used in dry mixes and supplements.
  • Hydrolysed or enzyme-modified lecithin, which has better water dispersibility for specific emulsions.
  • Fractionated lecithin, enriched in specific phospholipids for specialised uses.

Where it is used

  • Chocolate and confectionery: reduces viscosity so less cocoa butter is needed, and improves moulding.
  • Bakery: improves dough handling, volume and crumb, and acts as a release agent.
  • Margarine and spreads: stabilises emulsions and reduces spattering in frying.
  • Instant powders: helps milk powders, cocoa drinks and protein powders wet and dissolve.
  • Dairy alternatives: helps stabilise plant-based drinks and creams.
  • Supplements and pharmaceuticals: used in capsules and as a nutrient source.
  • Animal feed and industrial uses.

Sourcing: GM and non-GM

A large share of the world's soybeans are genetically modified. Some markets, especially in Europe, have strong demand for non-GM ingredients, and labelling rules may require disclosure. Non-GM soybean lecithin needs an identity-preserved supply chain, keeping non-GM beans separate through farming, storage, crushing and refining. This adds cost and makes certain origins more important.

Sunflower lecithin has grown as an alternative because it is generally non-GM and avoids soy allergen labelling.

Allergen considerations

Soy is a major allergen in many jurisdictions. Highly refined soybean oil may be exempt from allergen labelling in some places, but lecithin may still contain residual proteins. Rules vary, so manufacturers must check local requirements and label correctly.

Storage and stability

Lecithin is not a chilled ingredient, but temperature and handling still matter:

  • Fluid lecithin becomes very thick at low temperatures and may need gentle warming before pumping. Overheating can darken it and damage quality.
  • Oxidation can occur over time, especially with exposure to air, light and heat, causing off-flavours.
  • Moisture can cause de-oiled powders to cake.
  • Storage temperature should be stable and moderate, typically in sealed containers away from light.

For tank storage in food plants, manufacturers often use heated lines or agitation to keep fluid lecithin usable, and monitor temperature carefully.

Lecithin in chilled and frozen foods

In ice cream, frozen desserts, chilled dairy and plant-based drinks, lecithin supports emulsion stability. It can help reduce fat separation in plant-based milks and improve texture in frozen products. Stability through chilling, freezing and storage is tested as part of product development.

Market factors to watch

  1. Soybean prices and crushing volumes, which affect lecithin supply.
  2. Non-GM demand and certification.
  3. Competition from sunflower and rapeseed lecithin.
  4. Clean-label trends, where lecithin is often seen as more acceptable than some synthetic emulsifiers.
  5. Growth in plant-based foods.

Soybean lecithin is a byproduct, but its value in food manufacturing is significant. Good sourcing and careful handling keep it working in products from chocolate to plant-based milk.
