Turkish Oak (Light Roast) Extract

Light-roast Turkish oak supercritical CO₂ extract (Quercus cerris) delivers authentic cooperage character for beverage applications requiring subtle wood-aged notes without barrel contact. This amber, mobile viscous extract presents a phenolic aldehyde profile led by vanillin and syringaldehyde characteristic of toasted oak.

Functional Properties

Key aroma compounds include trans-coniferaldehyde (1.78%), sinapic aldehyde (1.45%), syringaldehyde (0.76%), and vanillin (0.52%)—the same molecules developed during barrel toasting. Total phenolic content reaches 114.1 mg GAE/g with DPPH IC₅₀ of 64.7 ppm, indicating significant antioxidant capacity. The lipid fraction features linoleic acid (2.31%), palmitic acid (1.29%), and sterols (γ-sitosterol 7.13%) with triterpenes (friedelan-3-one 6.57%, lupeol 1.39%).

Quality

Supercritical extraction from Turkish oak heartwood following controlled light-roast toasting. Phenolic aldehyde profile verified by HPLC-DAD. Complies with food-grade specifications for heavy metals and microbial contamination.

Applications

• Spirits: Vodka finishing, gin/genever complement, craft spirits enhancement
• Wine: White wine maturation surrogate, barrel-alternative applications
• Beverages: Natural flavoring for soft drinks, functional beverages

Recommended dosage: 0.5–2 mg/L, pre-dissolved in ≥40% ethanol before blending.
