What is Alpha-methyl-beta-hydroxypropyl Alpha-methyl-beta-mercaptopropyl Sulfide?
Alpha-methyl-beta-hydroxypropyl Alpha-methyl-beta-mercaptopropyl Sulfide is a synthetic flavoring compound identified by CAS number 54957-02-7. It belongs to the category of organosulfur compounds, which are characterized by the presence of sulfur atoms in their molecular structure. The presence of sulfur is chemically significant because sulfur-containing compounds are responsible for many characteristic savory, meaty, and umami flavor profiles found in foods. This additive is produced through chemical synthesis rather than extraction from natural sources.
Common Uses
This flavoring agent is primarily used in the food industry to enhance or create savory flavor profiles. Common applications include:
- Meat and poultry products
- Broth and stock-based foods
- Processed meat products
- Savory snack foods
- Soup and sauce formulations
- Ready-to-eat meal components
The compound functions by either providing direct flavor impact or by enhancing existing flavors, making it useful in applications where manufacturers seek to intensify savory or meaty taste characteristics with minimal additional ingredients.
Safety Assessment
According to FDA records, there have been zero reported adverse events associated with this additive and zero product recalls linked to its use. The absence of adverse event reports suggests no known safety incidents have been documented in the United States food supply.
However, it is important to note that this additive has not been granted GRAS (Generally Recognized as Safe) status by the FDA. GRAS status represents formal FDA acknowledgment that a substance is safe under its conditions of use, based on either a history of safe use or scientific evidence. The lack of GRAS status indicates that while the compound may be used in food, it has not undergone the formal FDA safety determination process.
The absence of GRAS status does not necessarily indicate a safety concern; rather, it reflects that either formal safety petitions have not been submitted to the FDA, or such petitions are still under review. Some flavor compounds operate under different regulatory frameworks, including provisions under 21 CFR 570.735(a) or through flavor industry self-regulation via the Flavor and Extract Manufacturers Association (FEMA).
Regulatory Status
In the United States, this compound appears to be in limited or specialized use within the food industry. Its regulatory status differs from broadly approved food additives, as it lacks explicit FDA GRAS determination. Manufacturers using this ingredient must ensure compliance with applicable FDA regulations for food additives and may need to maintain documentation of safe use practices.
Regulatory status may vary internationally. The European Food Safety Authority (EFSA) maintains separate approval lists for food flavorings. Interested parties should consult current EFSA or other regional regulatory body resources for approval status outside the United States.
Key Studies
Published scientific literature specifically examining the safety profile of this particular compound appears limited in the publicly available scientific database. The chemical similarity to other sulfur-containing flavor compounds used historically in food may provide some context, as the broader class of organosulfur flavorings has been studied. However, compound-specific toxicological data would be necessary to establish a comprehensive safety profile.
The combination of zero reported adverse events, zero recalls, and presence in the food supply suggests either safe historical use or limited exposure levels. Further safety evaluation or GRAS petition data would provide additional certainty regarding this additive's safety profile.
