Soy Lecithin

CAS 8002-43-5 · E322 · lecithin · soya lecithin

Soy-derived emulsifier and one of the most common food additives. EFSA found no safety concern at food-additive use levels; the main real-world caveat is that it is a soy allergen carrying trace phytoestrogenic isoflavones.

Researched July 7, 2026

Concerns

  • EFSA's 2017 re-evaluation and 2020 follow-up concluded lecithins (E 322) raise no safety concern at the maximum permitted food-additive use levels, and considered no numerical ADI necessary (EFSA 2020)
  • As a soy-derived ingredient it can be an allergen for soy-allergic individuals, and residual soy isoflavones give it a weak, largely theoretical phytoestrogenic profile [Inference]

Regulatory flags

  • IARC Class: NL
  • EDC Status: None established (weak phytoestrogen suspected)
  • Regulatory: US: GRAS; EU: permitted (E 322), no numerical ADI
  • Evidence Grade: A
