FlavScents AInsights Entry for Betaine (CAS: 107-43-7)

1. Identity & Chemical Information

Common Name(s): Betaine
IUPAC Name: Trimethylglycine
CAS Number: 107-43-7
FEMA Number: Not applicable
Other Identifiers: FL Number: 09.011
Molecular Formula: C5H11NO2
Molecular Weight: 117.15 g/mol

Betaine is a zwitterionic compound characterized by a quaternary ammonium group and a carboxylate group. Its structure contributes to its hygroscopic nature and its role as an osmoprotectant. The presence of the trimethylammonium group is significant for its odor profile, although betaine itself is not typically noted for a strong odor.

2. Sensory Profile

Betaine is not primarily known for its sensory attributes in terms of odor or flavor. It is generally considered odorless and has a slightly sweet taste. Its sensory role is more functional, often used to enhance the sweetness or modify the mouthfeel of products rather than imparting a distinct flavor or aroma. The taste threshold for betaine is not well-documented, reflecting its secondary role in sensory applications.

3. Natural Occurrence & Formation

Betaine naturally occurs in a variety of plant and animal sources, including sugar beets, spinach, and seafood. It is formed through the oxidation of choline and plays a crucial role in the metabolism of homocysteine. Its presence in natural sources qualifies it for use in products labeled as containing "natural flavors."

4. Use in Flavors

Betaine is utilized in flavor systems primarily for its ability to enhance sweetness and improve mouthfeel. It is commonly used in beverages, confectionery, and dairy products. Typical use levels in finished products range from 50 to 500 ppm, depending on the desired effect and product type. Betaine is stable under a variety of conditions, including heat and pH variations, making it versatile in formulation.

5. Use in Fragrances

In fragrance applications, betaine is not typically used for its scent but rather for its functional properties, such as improving the solubility of other fragrance components or enhancing skin feel in personal care products. Its contribution to fragrance systems is more about formulation enhancement than direct olfactory impact.

6. Regulatory Status (Regional Overview)

United States: Betaine is generally recognized as safe (GRAS) for use in food products.
European Union: Approved under Regulation (EC) No 1334/2008 with FL number 09.011.
United Kingdom: Follows EU regulations post-Brexit.
Asia: Approved for use in Japan and China, with specific regulations varying by country.
Latin America: Generally accepted, but specific regulations should be consulted for each country.

7. Toxicology, Safety & Exposure Considerations

Betaine is considered safe for oral consumption with a high margin of safety. It is non-irritating and non-sensitizing for dermal exposure, making it suitable for use in personal care products. Inhalation exposure is not typically a concern due to its low volatility. Overall, betaine has a favorable safety profile across its applications.

8. Practical Insights for Formulators

Betaine is valued for its multifunctional role in formulations, enhancing sweetness and improving texture. It synergizes well with other sweeteners and can help mask off-flavors. Formulators should be aware of its hygroscopic nature, which may affect product stability in high-moisture environments. It is often underutilized in applications where its functional benefits could be maximized.

9. Confidence & Data Quality Notes

The data on betaine is well-established, particularly regarding its safety and functional roles. While sensory data is limited, its applications are well-documented in industry literature. Regulatory information is clear, though formulators should verify specific regional requirements.

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.
