What is Sodium 3-methoxy-4-hydroxycinnamate?
Sodium 3-methoxy-4-hydroxycinnamate (CAS Number: 24276-84-4) is the sodium salt of ferulic acid, a naturally occurring phenolic compound found in plant materials including grains, seeds, and coffee. This compound belongs to the class of organic acids and their derivatives commonly used in food flavoring applications. The chemical structure consists of a benzene ring with methoxy and hydroxy functional groups, attached to a propionic acid chain, which when converted to its sodium salt form, becomes soluble and suitable for food applications.
Common Uses
Sodium 3-methoxy-4-hydroxycinnamate is used as a flavoring agent and flavor adjuvant in the food industry. Its applications typically include:
- Enhancement of bitter or savory flavor notes in processed foods
- Adjustment of overall flavor profiles in beverages and beverages concentrates
- Use as a sensory compound in specialty food formulations
- Potential use in functional food products
The compound is valued for its ability to modify and enhance existing flavors rather than provide a distinct taste on its own. Because it is derived from natural sources, it appeals to manufacturers seeking ingredients with natural origins.
Safety Assessment
Sodium 3-methoxy-4-hydroxycinnamate has a limited history of use in food applications in most jurisdictions. As of current FDA records, there are zero reported adverse events linked to this additive and zero product recalls citing this ingredient as a concern. This absence of reported incidents suggests that when used in food products, it has not generated consumer health complaints or safety flags at the regulatory level.
The compound is structurally related to ferulic acid, which is recognized as a naturally occurring substance with a longer history of use in traditional foods and supplements. However, the specific sodium salt form (sodium ferulate) has a more limited safety database compared to some other food additives.
It is important to note that the lack of adverse event reports does not constitute a formal safety approval. Rather, it indicates an absence of documented harm in real-world food applications to date.
Regulatory Status
Sodium 3-methoxy-4-hydroxycinnamate is not on the FDA's Generally Recognized as Safe (GRAS) list. This means the compound has not undergone the formal GRAS notification process or received explicit FDA approval as a food additive in the United States.
In the European Union, ferulic acid and related compounds have varying regulatory statuses depending on specific product categories. Some forms may be permitted under EU food additive regulations, while others may require individual assessment.
Manufacturers seeking to use this ingredient in food products should verify current regulatory requirements in their target markets, as regulations differ significantly between countries. In the United States, food manufacturers must ensure compliance with FDA regulations before marketing products containing this ingredient.
Key Studies
Scientific literature on sodium 3-methoxy-4-hydroxycinnamate specifically is limited. Most research on related compounds focuses on ferulic acid itself, which has been studied for antioxidant and other biochemical properties in nutritional and pharmaceutical contexts.
Studies on ferulic acid and its derivatives have generally demonstrated low acute toxicity in animal models, though comprehensive safety data specific to the food additive application of the sodium salt form remains limited in published peer-reviewed literature.
Any organization considering the use of this ingredient should consult current scientific literature and regulatory guidance specific to their intended application and geographic market.
