What is Ethyl maltol?

Ethyl maltol (CAS 4940-11-8), also marketed as Veltol Plus and designated E637, is a synthetic flavour enhancer approximately four to six times more potent than maltol.

Where is Ethyl maltol used?

  • Food and beverage: amplifies and rounds out sweet, fruity, and caramellic notes
  • Confectionery, bakery, and soft drinks: boosts perceived sweetness and extends flavour longevity at use levels typically below 50 ppm
  • Tobacco: smooths harshness and adds a sweet, creamy character
  • Personal care and cosmetics: fragrance modifier enhancing vanilla, fruity, and gourmand scent profiles in perfumes and lotions
  • Lip products: improves the sensory experience
  • Fat-containing formulations: chelating behaviour supports oxidative stability and reduces rancidity
  • It allows manufacturers to reduce sugar or other flavouring inputs without sacrificing the overall taste profile.

Good to know: Food-grade material conforming to FCC and purity specifications is the standard commercial form for flavour and food applications; technical-grade material is available for non-food industrial use where high purity is not the primary requirement.
