About
Turkish Oak (Medium Roast) Extract is a water-dispersible scCO₂ extract of Quercus cerris heartwood, taken from medium-toast cooperage staves. A dark amber oil-in-water emulsion with a toasted-oak, whisky-like, vanillic and smoky-sweet aroma.
Functional Properties
The extract reproduces the aroma chemistry a barrel builds over months of contact. Toast markers are specified individually: vanillin >0.04%, syringaldehyde >0.10%, trans-coniferaldehyde >0.40%, sinapic aldehyde >0.20% and 5-hydroxymethylfurfural >0.40%, totalling >1.2%. It also carries a measurable phenolic load: total phenolic content >15 mg GAE/g, DPPH IC₅₀ <800 ppm.
Quality
Aroma compounds and fatty acids by GC-MS / GC-FID; total major fatty acids >0.49%. Heavy metals and pathogens not detected. Raw material: total ash <4%, benzo(a)pyrene <10 ppb. Shelf life 12 months unopened at 2–8 °C.
Applications
- Spirits and wine: barrel-maturation surrogate; pre-dissolve in neutral spirit (≥40% ethanol) before blending
- Confectionery and bakery: oak-vanilla and smoky-sweet notes in fillings and doughs
- Sauces: barrel-aged character in barbecue sauces, glazes and marinades
