FlavScents AInsights Entry: Citrus Medica Vulgaris Fruit Extract (CAS: 92346-90-2)
1. Identity & Chemical Information
Citrus medica vulgaris fruit extract, commonly known as citron extract, is a natural complex material derived from the fruit of the Citrus medica plant. This extract is not a single chemical compound but a mixture of various constituents. The CAS number for this extract is 92346-90-2. It does not have a specific FEMA number as it is a complex mixture rather than a single compound. Other identifiers such as FL number, CoE number, or IFRA reference are not typically assigned to complex natural materials like this extract. The composition of the extract can vary significantly depending on the origin, harvest time, and processing methods used.

3. Natural Occurrence & Formation
Citrus medica vulgaris, or citron, is a fruit-bearing tree native to Southeast Asia but now cultivated in various regions worldwide, including the Mediterranean and parts of the Americas. The fruit extract is obtained through cold pressing or steam distillation of the fruit peel. The extract is considered a natural flavor and fragrance material, aligning with consumer preferences for natural ingredients. The formation of its characteristic aroma compounds involves enzymatic processes within the fruit as it ripens.

6. Regulatory Status (Regional Overview)
In the United States, citrus medica vulgaris fruit extract is generally recognized as safe (GRAS) for use in food and beverages. In the European Union, it is regulated under Regulation (EC) No 1334/2008, and its use in flavors is permitted. The United Kingdom follows similar regulations post-Brexit. In Asia, including Japan and China, the extract is used in compliance with local food safety standards. In Latin America, countries like Brazil and members of MERCOSUR have their own regulations, which generally align with international standards. However, formulators should be aware of any specific restrictions or labeling requirements in each region.

7. Toxicology, Safety & Exposure Considerations
Citrus medica vulgaris fruit extract is considered safe for use in food and fragrance applications when used within recommended levels. Oral exposure through flavor use is generally low, with no specific ADI or MSDI established, but it is considered safe under GRAS conditions. Dermal exposure in fragrance applications is also considered safe, with no significant reports of irritation or sensitization. Inhalation exposure is minimal due to the low volatility of the extract's heavier components. Overall, the risk profiles for food and fragrance applications are similar, with no significant safety concerns reported.

8. Practical Insights for Formulators
Citrus medica vulgaris fruit extract is valued for its ability to impart a natural and authentic citrus note to both flavors and fragrances. It synergizes well with other citrus and floral ingredients, enhancing the overall complexity and appeal of formulations. Common pitfalls include overuse, which can lead to an overpowering or artificial perception, and underuse, which may result in a lack of impact. Formulators should carefully balance the extract with other components to achieve the desired sensory profile.

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.
