What is 2-methyl-3-furyl 2-methyl-3-tetrahydrofuryl Disulfide?
2-methyl-3-furyl 2-methyl-3-tetrahydrofuryl Disulfide (CAS Number: 252736-40-6) is a synthetic organic compound belonging to the disulfide chemical family. It consists of two heterocyclic ring structures connected by a disulfide bond (S-S linkage). The compound is classified as a flavoring agent and is used in minute quantities in food formulations.
Due to its molecular structure, this additive belongs to a category of sulfur-containing flavor compounds that naturally occur in foods like roasted meats, cooked vegetables, and fermented products. Synthetic versions are manufactured to provide consistent flavor profiles in industrial food production.
Common Uses
This flavoring compound is primarily used in:
- Processed meat products and meat analogs
- Savory snack foods and seasonings
- Soup and broth bases
- Gravy and sauce formulations
- Ready-to-eat meal components
- Flavor blends and seasoning mixtures
As a flavoring agent, it is used at very low concentrations—typically measured in parts per million (ppm)—to add depth, savory character, and roasted notes to foods. Its disulfide structure contributes meaty and umami-like qualities that enhance perceived palatability.
Safety Assessment
The FDA does not list this compound as Generally Recognized as Safe (GRAS), which means it has not received formal GRAS affirmation through the standard notification process. However, this regulatory status does not indicate unsafe use; rather, it reflects the limited volume of use and available safety data.
Key safety observations include:
- No adverse events reported to the FDA
- No recalls associated with this additive
- No documented consumer complaints or safety incidents
- Typical use levels are extremely low (parts per million)
Due to the minimal quantities used in food applications, systemic exposure is expected to be very limited. Disulfide compounds are metabolized in the body through standard detoxification pathways. The chemical structure is relatively stable and does not exhibit properties associated with genotoxicity or bioaccumulation.
The European Food Safety Authority (EFSA) has not specifically assessed this compound, as it falls outside the scope of flavor compounds commonly used in European food markets.
Regulatory Status
In the United States, this additive may be used under FDA regulations governing flavoring substances when not specifically prohibited. It does not require premarket approval if used as intended for flavoring purposes at recognized safe levels.
The compound is not on the FDA's list of banned or restricted food additives. Its non-GRAS status means manufacturers using it may rely on historical use or proprietary safety assessments, though the FDA retains authority to challenge its safety if concerns emerge.
Globally, regulatory status varies by jurisdiction. Many countries do not maintain specific records for this specialized flavoring compound, and its use would be subject to local flavor and additive regulations.
Key Studies
Limited published scientific literature is available for this specific compound due to its narrow application and relatively recent synthetic development. Safety assessments have primarily been conducted by flavor manufacturers and suppliers using:
- Standard toxicology screening protocols
- Metabolism studies evaluating disulfide bond breakdown
- Acute and subchronic toxicity data
- Assessment against structurally similar approved flavor compounds
The absence of adverse event reports and zero recalls suggest that any safety issues have not manifested in real-world use. However, the limited published peer-reviewed research means this compound has not undergone the same level of public scientific scrutiny as more widely used additives.
Flavorings in general are used at very low levels and are considered among the safest food additives by regulatory agencies worldwide.
