About
Medium-roast Turkish oak supercritical CO₂ extract (Quercus cerris) reproduces the balanced toasted-oak, vanilla, smoky-sweet profile characteristic of barrel-aged wines and whiskies. This dark-amber, viscous oleoresin presents a harmonious phenolic aldehyde composition ideal for accelerated maturation applications.
Functional Properties
The balanced profile features 5-hydroxymethylfurfural (>4.00%) contributing caramelized sweetness, trans-coniferaldehyde (>4.00%) providing woody depth, sinapic aldehyde (>2.00%) adding complexity, syringaldehyde (>1.00%), and vanillin (>0.40%) for classic barrel notes. Total phenolic content exceeds 150 mg GAE/g with strong antioxidant capacity (DPPH IC₅₀: <80 ppm).
Quality
Supercritical extraction from Turkish oak heartwood following controlled medium-roast toasting. Aroma compounds verified by GC-MS/GC-FID, total phenolics by Folin-Ciocalteu.
Applications
- Spirits: Whisky barrel-maturation substitute, accelerated aroma development
- Wine: Oak-aging alternative, wine finishing applications
- Confectionery: Vanilla-oak flavor systems, premium chocolate notes
Typical dosage: 1–5 mg/L in finished spirit or wine, 1–10 mg/kg in confectionery. Pre-dissolve in ≥40% ethanol.
