FlavScents AInsights Entry: Hedychium flavescens Root Extract (CAS: 94334-08-4)
1. Identity & Chemical Information
Hedychium flavescens root extract is a natural complex material derived from the roots of the Hedychium flavescens plant, commonly known as yellow ginger lily. This extract is not a single chemical compound but a mixture of various constituents. The CAS number for this extract is 94334-08-4. It does not have a specific FEMA number or other identifiers like FL or CoE numbers due to its complex nature. As a natural extract, its composition can vary significantly depending on the geographical origin, harvest time, and processing methods used.

2. Sensory Profile
The sensory profile of Hedychium flavescens root extract is characterized by a warm, spicy, and slightly woody aroma with floral undertones. It is often described as having a moderate intensity and a lingering diffusion. This extract is typically used as a background realism note in both flavor and fragrance formulations, providing a subtle complexity that enhances the overall sensory experience. Specific odor and taste thresholds are not well-documented, but it is generally used in low concentrations to avoid overpowering other components.

3. Natural Occurrence & Formation
Hedychium flavescens is native to the Himalayan region and is widely cultivated in tropical and subtropical areas. The root extract is obtained through steam distillation or solvent extraction of the plant's rhizomes. This extract is considered a natural flavor and fragrance material, aligning with consumer preferences for natural products. The formation of its characteristic aroma is primarily due to the presence of various terpenes and sesquiterpenes, which are naturally occurring in the plant.

4. Use in Flavors
In flavor applications, Hedychium flavescens root extract is used in a variety of categories, including spice blends, savory sauces, and exotic fruit flavors. It serves as a functional background note that enhances the complexity and depth of flavor systems. Typical use levels in finished food products range from 0.1 to 5 ppm, depending on the desired intensity and the specific application. The extract is relatively stable under heat and acidic conditions but may oxidize over time, affecting its sensory properties.

5. Use in Fragrances
Hedychium flavescens root extract is utilized in fragrance formulations across several families, including oriental, woody, and floral compositions. It acts as a modifier and impact note, contributing to the fragrance's overall warmth and depth. Typical concentration ranges in perfumes and personal care products are between 0.05% and 0.5%. The extract is considered a middle to base note due to its moderate volatility and lasting presence.

6. Regulatory Status (Regional Overview)
In the United States, Hedychium flavescens root extract is generally recognized as safe (GRAS) for use in flavors by FEMA. In the European Union, it is subject to the regulations outlined in Reg. (EC) No 1334/2008, although specific FL number status is not assigned. The United Kingdom follows similar regulations post-Brexit. In Asia, particularly in Japan and China, the extract is used in traditional medicine and flavor applications, but specific regulatory details may vary. In Latin America, countries like Brazil and members of MERCOSUR have their own guidelines, often harmonized with international standards.

7. Toxicology, Safety & Exposure Considerations
The safety profile of Hedychium flavescens root extract is generally favorable, with no significant toxicological concerns reported at typical use levels. For oral exposure in flavor applications, the extract is considered safe within the established ppm ranges. Dermal exposure in fragrance use is also deemed safe, with no reports of irritation or sensitization at typical concentrations. Inhalation exposure is minimal due to its moderate volatility, but occupational safety measures should be observed during handling and processing.

8. Practical Insights for Formulators
Hedychium flavescens root extract is valued for its ability to add warmth and complexity to both flavors and fragrances. It synergizes well with other spicy and woody notes, enhancing the overall sensory profile. Formulators should be cautious of its potential to overpower delicate compositions if used excessively. It is often under-utilized in formulations seeking a natural and exotic character.

9. Confidence & Data Quality Notes
The data on Hedychium flavescens root extract is well-established in terms of its sensory profile and typical applications. However, there are gaps in specific regulatory approvals and toxicological data, particularly in non-Western markets. Industry practices often rely on traditional knowledge and empirical use rather than documented studies.

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.
