What Is Sunflower Lecithin and How Much Should I Use?

Quick answer (TL;DR): Sunflower lecithin is a non-GMO, allergen-friendly emulsifier extracted mechanically (no hexane) from sunflower seeds. Use 0.3–0.5 % of total recipe weight for chocolate, 0.2 % for baked goods, and 0.6 % for high-fat nut milks to keep oil and water phases perfectly blended.

Right: Conventional soy lecithin – may contain GMOs and allergens.

Why Choose Sunflower Over Soy Lecithin?

  • Allergen-friendly: No common soy proteins.
  • Non-GMO by default – most sunflower crops are non-GMO.
  • Cold-press extraction: avoids hexane solvents used in soy processing.
  • Mild flavour: neutral taste versus soy’s beany note.

Recommended Dosage by Application

Product Typical lecithin rate Notes
Dark / milk chocolate 0.3 – 0.5 % Add during final 10 min of conching; replace up to 10 % of added cocoa butter.
Cookies / cakes 0.2 % Blend with fat phase; improves crumb and extends shelf life.
Plant-based milk 0.6 % High-shear blend with warm water (≥ 50 °C) for full dispersion.
Vegan mayonnaise 0.4 % Whisk into oil before emulsifying with aquafaba or soy milk.


How to Disperse Sunflower Lecithin

  1. Powder form: whisk into warm fat phase (40 – 60 °C) until dissolved.
  2. Granules: grind or pre-soak in 3 × weight hot oil, then shear-blend.
  3. Avoid moisture first: lecithin hydrates and clumps if added directly to water before it’s in solution.

FAQs Within the FAQ

Can I replace soy lecithin 1:1 with sunflower?

Yes—sunflower lecithin matches HLB and phospholipid profile; use the same %.

Will lecithin make chocolate thicker?

In small amounts (≤ 0.5 %), lecithin reduces viscosity by lowering surface tension—allowing you to cut cocoa butter.
