1. Identity & Chemical Information

Common Name(s): Shoyu furanone
IUPAC Name: 4-Hydroxy-5-methyl-3(2H)-furanone
CAS Number: 27538-09-6
FEMA Number: Not available
Other Identifiers: FL number not available; CoE number not available; IFRA reference not available
Molecular Formula: C5H6O3
Molecular Weight: 114.10 g/mol
Functional Groups and Structure–Odor Relevance: Shoyu furanone contains a furanone ring with a hydroxyl group, contributing to its sweet, caramel-like odor profile. The presence of the hydroxyl group is significant for its solubility and reactivity in flavor systems.

Citation hooks: FlavScents; PubChem; FEMA

2. Sensory Profile

Odor and Flavor Descriptors: Shoyu furanone is characterized by a sweet, caramel-like aroma with nuances of maple and burnt sugar. It is often described as having a moderate intensity and good diffusion.
Taste and/or Odor Thresholds: Specific thresholds are not clearly reported, but it is known to be effective at low concentrations in flavor applications.
Typical Sensory Role: It serves as an impact note in flavor formulations, providing depth and complexity to sweet profiles.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Known Natural Sources: Shoyu furanone is naturally found in soy sauce, roasted coffee, and certain types of caramelized sugar.
Formation Pathways: It is primarily formed through the Maillard reaction, a chemical reaction between amino acids and reducing sugars that occurs during the cooking process.
Relevance to “Natural Flavor” or “Natural Fragrance” Designation: Due to its natural occurrence in food products, it can be labeled as a natural flavor in certain regulatory contexts.

Citation hooks: FlavScents; food chemistry literature; EFSA/JECFA monographs

4. Use in Flavors

Flavor Categories and Applications: Shoyu furanone is used in a variety of flavor categories, including bakery, confectionery, and savory applications.
Functional Role in Flavor Systems: It acts as a flavor enhancer and modifier, contributing to the overall sweetness and depth of the flavor profile.
Typical Use Levels: Documented use levels range from 0.1 to 5 ppm in finished food products, with typical levels around 1 ppm.
Stability Considerations: It is relatively stable under heat but may degrade under highly acidic or oxidative conditions.

6. Regulatory Status (Regional Overview)

United States (FDA / FEMA GRAS): Not explicitly listed as GRAS by FEMA.
European Union (Reg. (EC) No 1334/2008): Not specifically listed; may be used under general flavoring regulations.
United Kingdom: Follows EU regulations post-Brexit with no specific divergence reported.
Asia (Japan, China, ASEAN): Limited specific data; generally follows international flavoring standards.
Latin America (e.g., Brazil, MERCOSUR): Not explicitly listed; usage may be subject to general flavoring regulations.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: No specific ADI or MSDI values are available; considered safe at typical flavor use levels.
Dermal Exposure: Limited data on irritation or sensitization; generally considered low risk in fragrance applications.
Inhalation Exposure: Volatility suggests low occupational risk at typical use concentrations.
Risk Profiles: No significant differences in risk profiles between food and fragrance applications.

Citation hooks: EFSA; FEMA; PubChem; toxicology literature

8. Practical Insights for Formulators

Why This Material is Valuable: Shoyu furanone is prized for its ability to impart a rich, caramel-like sweetness that enhances the complexity of both flavors and fragrances.
Typical Synergies: Works well with vanilla, chocolate, and nutty notes.
Common Formulation Pitfalls: Overuse can lead to an overpowering sweetness; balance is key.
Situations Where It is Frequently Over- or Under-used: Often under-used in savory applications where a hint of sweetness can enhance umami flavors.

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.
