2. Sensory Profile
The sensory profile of European hazelnut oil CO2 extract is characterized by its rich, nutty aroma with sweet, creamy undertones. It is often described as having a warm, roasted quality that is both intense and long-lasting. The extract serves as an impact note in formulations, providing a realistic nutty character that can enhance both flavor and fragrance compositions. Specific odor and taste thresholds are not well-documented, but its potent aroma suggests it is effective even at low concentrations.

3. Natural Occurrence & Formation
European hazelnut oil CO2 extract is obtained from the nuts of the Corylus avellana tree, commonly known as the European hazel. The extraction process typically involves supercritical CO2, which preserves the delicate aroma compounds. This extract is considered a natural flavor and fragrance material, aligning with consumer preferences for natural ingredients. The formation of its characteristic aroma is primarily due to the presence of volatile compounds developed during the nut's maturation and processing.

4. Use in Flavors
In flavor applications, European hazelnut oil CO2 extract is used to impart a rich, authentic nutty taste to a variety of products, including confectionery, baked goods, and dairy products. It functions as both an impact note and a background enhancer, providing depth and complexity. Typical use levels in finished food products range from 5 to 50 ppm, depending on the desired intensity and product type. The extract is generally stable under typical food processing conditions, though it may be sensitive to high heat and prolonged exposure to air.

6. Regulatory Status (Regional Overview)
In the United States, European hazelnut oil CO2 extract is generally recognized as safe (GRAS) for use in flavors. In the European Union, it is regulated under Regulation (EC) No 1334/2008, with specific FL number status not clearly reported. The United Kingdom follows similar regulations post-Brexit. In Asia, regulatory acceptance varies, with Japan and China having specific guidelines for natural extracts. In Latin America, countries like Brazil and those in MERCOSUR may have their own regulatory frameworks, often aligning with international standards.

7. Toxicology, Safety & Exposure Considerations
For oral exposure, European hazelnut oil CO2 extract is considered safe within typical use levels, with no specific ADI or MSDI established. Dermal exposure in fragrance applications is generally low risk, though sensitization potential should be evaluated, particularly for sensitive skin. Inhalation exposure is minimal due to its moderate volatility, but occupational safety measures should be in place during handling. Overall, the risk profiles for food and fragrance applications are similar, with no significant safety concerns reported.

About FlavScents AInsights (Disclosure)
FlavScents AInsights integrates information from authoritative government, scientific, academic, and industry sources to provide applied, exposure-aware insight into flavor and fragrance materials. Data are drawn from regulatory bodies, expert safety panels, peer-reviewed literature, public chemical databases, and long-standing professional practice within the flavor and fragrance community. Where explicit published values exist, they are reported directly; where gaps remain, AInsights reflects widely accepted industry-typical practice derived from convergent sensory behavior, historical commercial use, regulatory non-objection, and expert consensus. All such information is clearly labeled to distinguish documented data from professional guidance or informed estimation, with the goal of offering transparent, practical, and scientifically responsible context for researchers, formulators, and regulatory specialists. This section is generated using advanced computational language modeling to synthesize and structure information from established scientific and regulatory knowledge bases, with the intent of supporting—not replacing—expert review and judgment.
