FlavScents AInsights Entry: Ferric Ammonium Citrate Green Salt (CAS: 1185-57-5)

1. Identity & Chemical Information

Common Name(s): Ferric Ammonium Citrate Green Salt
IUPAC Name: Ammonium iron(III) citrate
CAS Number: 1185-57-5
FEMA Number: Not applicable
Other Identifiers: Not applicable
Molecular Formula: C6H8FeNO7
Molecular Weight: 244.97 g/mol

Ferric ammonium citrate is a coordination complex of iron(III) with ammonium and citrate ions. The green salt variant is characterized by its specific iron content and the presence of citrate, which influences its solubility and reactivity. The functional groups include carboxylate and ammonium ions, which contribute to its stability and interaction with other compounds. Its structure is relevant to its use in various applications, including its role as a source of iron in dietary supplements and its potential use in flavor and fragrance formulations.

2. Sensory Profile

Ferric ammonium citrate green salt does not have a significant odor or flavor profile that is typically utilized in flavor or fragrance applications. Its primary sensory role is not as a direct contributor to taste or aroma but rather as a functional ingredient that may influence the overall sensory characteristics of a formulation through its chemical interactions.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Ferric ammonium citrate is not naturally occurring and is synthesized through the reaction of ferric hydroxide with citric acid and ammonium hydroxide. This synthetic pathway allows for the controlled production of the compound, ensuring consistency in its chemical properties. It is not typically associated with "natural flavor" or "natural fragrance" designations due to its synthetic origin.

4. Use in Flavors

Ferric ammonium citrate is primarily used as a source of iron in dietary supplements and fortified foods rather than as a direct flavoring agent. Its role in flavor systems is more functional, contributing to the nutritional profile rather than the sensory characteristics. Typical use levels in food products are determined by nutritional requirements rather than flavor impact, and specific ppm ranges are not typically documented for flavor purposes.

5. Use in Fragrances

In fragrance applications, ferric ammonium citrate is not commonly used as a primary ingredient due to its lack of a distinct aroma profile. However, it may be included in formulations where its chemical properties can influence the stability or interaction of other fragrance components. Its contribution is more likely to be as a modifier or stabilizer rather than a direct scent contributor.

6. Regulatory Status (Regional Overview)

United States: Ferric ammonium citrate is recognized as GRAS (Generally Recognized As Safe) for use as a nutrient supplement.
European Union: Approved for use as a food additive under specific conditions.
United Kingdom: Follows EU regulations post-Brexit with no significant divergence reported.
Asia: Approved in several countries, including Japan and China, primarily for nutritional purposes.
Latin America: Generally accepted in countries like Brazil, with specific regulations depending on the application.

The regulatory status primarily focuses on its use as a nutritional supplement rather than a flavor or fragrance ingredient.

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Ferric ammonium citrate is considered safe for oral consumption within established dietary limits. The Acceptable Daily Intake (ADI) is based on its role as an iron supplement.
Dermal Exposure: Not typically associated with dermal applications; limited data on irritation or sensitization.
Inhalation Exposure: Not relevant for typical use scenarios; low volatility minimizes inhalation risk.

The risk profile is primarily concerned with its nutritional use, with safety assessments focusing on iron content and bioavailability.

8. Practical Insights for Formulators

Ferric ammonium citrate is valued for its role as an iron source in nutritional products. Formulators should consider its solubility and stability in various matrices. It is often used in conjunction with other ingredients to enhance bioavailability and minimize potential interactions that could affect product quality. Common pitfalls include overuse leading to metallic off-flavors or interactions with other components that may affect stability.

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.
