FlavScents AInsights Entry: Alpinia Officinarum Root Extract (CAS: 90320-42-6)
1. Identity & Chemical Information
Alpinia officinarum root extract, commonly known as galangal root extract, is derived from the rhizomes of the Alpinia officinarum plant. This extract is a natural complex material, not a single chemical compound, and is characterized by a mixture of various constituents. The CAS number for this extract is 90320-42-6. It does not have a specific FEMA number or IUPAC name due to its complex nature. Other identifiers such as FL number and CoE number are not clearly reported for this extract. The composition of the extract can vary significantly depending on the geographical origin, harvest time, and processing methods.

2. Sensory Profile
Alpinia officinarum root extract is known for its warm, spicy, and slightly sweet aroma, reminiscent of ginger and pepper. It is often described as having a pungent, earthy character with a hint of citrus. The intensity of the odor can vary, but it generally serves as an impact note in formulations. The taste is similarly spicy and warm, with a slight bitterness. Specific odor and taste thresholds are not well-documented, but the extract is typically used to impart a distinctive, exotic flavor and aroma to products.

3. Natural Occurrence & Formation
Alpinia officinarum is native to Southeast Asia, particularly China and Thailand, where it is cultivated for its aromatic rhizomes. The extract is obtained through processes such as steam distillation or solvent extraction. It is considered a natural flavor and fragrance material, aligning with "natural flavor" or "natural fragrance" designations due to its direct derivation from plant sources. The formation of its characteristic aroma compounds involves enzymatic processes within the plant tissues.

6. Regulatory Status (Regional Overview)
In the United States, alpinia officinarum root extract is generally recognized as safe (GRAS) for flavor use by FEMA. In the European Union, it is regulated under Regulation (EC) No 1334/2008, although specific FL number status is not clearly reported. The United Kingdom follows similar regulations post-Brexit. In Asia, including Japan and China, the extract is used in traditional medicine and culinary applications, but specific regulatory details may vary. In Latin America, such as Brazil, it is used in both food and fragrance applications, with regulations aligning with international standards.

7. Toxicology, Safety & Exposure Considerations
For oral exposure, alpinia officinarum root extract is considered safe at typical use levels in food, with no specific ADI or MSDI established. Dermal exposure in fragrance applications is generally safe, but formulators should be aware of potential sensitization in sensitive individuals. Inhalation exposure is not typically a concern at normal use levels, but occupational exposure should be managed to avoid irritation. The risk profiles for food and fragrance applications are similar, with no significant differences noted.

8. Practical Insights for Formulators
Alpinia officinarum root extract is valued for its ability to impart a warm, spicy character to both flavors and fragrances. It synergizes well with other spicy and citrus notes, enhancing complexity. Formulators should be cautious of overuse, which can lead to an overpowering effect. It is often underutilized in savory applications, where it can add depth and warmth.

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.
