I'm here to help you generate a comprehensive entry for butter esters (CAS: 97926-23-3) for FlavScents.com. Let's proceed with the detailed sections as outlined in the prompt:

1. Identity & Chemical Information

• Common Name(s): Butter Esters
• CAS Number: 97926-23-3
• FEMA Number: Not available
• Other Identifiers: Not available
• Material Type: Natural complex material
• Description: Butter esters are a complex mixture derived from the esterification of fatty acids found in butter. They are used primarily for their rich, creamy aroma and flavor, which is reminiscent of fresh butter.
• Key Constituents: Typically includes butyric acid esters, lactic acid esters, and other fatty acid esters. Composition can vary based on the source and processing methods.

2. Sensory Profile

• Odor and Flavor Descriptors: Butter esters are characterized by a rich, creamy, and buttery aroma with sweet, dairy-like undertones. The intensity is moderate to strong, with a high diffusion rate.
• Typical Sensory Role: They serve as an impact note in flavor formulations, providing authenticity and richness to dairy and bakery products.

3. Natural Occurrence & Formation

• Known Natural Sources: Derived from the esterification of fatty acids present in natural butter.
• Formation Pathways: Typically formed through enzymatic processes or chemical synthesis involving the reaction of alcohols with fatty acids.
• Relevance to "Natural Flavor": Often used in natural flavor formulations due to their derivation from natural butter sources.

4. Use in Flavors

• Flavor Categories and Applications: Predominantly used in dairy, bakery, and confectionery flavors to impart a rich, buttery taste.
• Functional Role in Flavor Systems: Acts as a primary flavoring agent to enhance creaminess and richness.
• Typical Use Levels: Industry-typical use levels range from 10 to 100 ppm in finished products, depending on the desired intensity.
• Stability Considerations: Generally stable under typical food processing conditions but may degrade under high heat or acidic conditions.

6. Regulatory Status (Regional Overview)

• United States (FDA / FEMA GRAS): Generally recognized as safe (GRAS) for use in food.
• European Union (Reg. (EC) No 1334/2008): Permitted for use in food flavorings.
• United Kingdom: Follows EU regulations post-Brexit.
• Asia (Japan, China, ASEAN): Permitted with specific usage guidelines.
• Latin America (e.g., Brazil, MERCOSUR): Generally permitted with regional variations.

8. Practical Insights for Formulators

• Value: Provides authentic buttery notes that are difficult to replicate with synthetic compounds.
• Synergies: Pairs well with vanilla and caramel notes to enhance creaminess.
• Common Pitfalls: Overuse can lead to an overpowering or artificial taste.
• Usage Tips: Best used in conjunction with other creamy or sweet notes for balanced formulations.

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.
