Ampelopsin D is a flavonoid glycoside, characterized by its multiple hydroxyl groups, which contribute to its solubility and potential antioxidant properties. The presence of these functional groups is significant for its interaction with other compounds, influencing its sensory attributes and stability in formulations.

2. Sensory Profile

Ampelopsin D is not primarily known for its distinct odor or flavor profile, as it is more commonly recognized for its bioactive properties. However, in formulations where it is used, it may contribute subtle sweet and astringent notes, typical of many flavonoid compounds. Its sensory role is often as a background modifier, enhancing the complexity of the flavor profile without being a dominant note.

3. Natural Occurrence & Formation

Ampelopsin D is naturally found in various plant species, particularly within the Vitaceae family. It is commonly extracted from the leaves and stems of Ampelopsis species. The compound is biosynthesized through the flavonoid pathway, involving the enzymatic conversion of phenylalanine to various flavonoid structures. Its presence in plants is often associated with defense mechanisms against pathogens and UV radiation.

4. Use in Flavors

Ampelopsin D is not widely used as a direct flavoring agent due to its limited sensory impact. However, it may be included in flavor systems for its potential health benefits and as a natural antioxidant. Typical use levels in food and beverages are not well-documented, but when used, it is generally at low concentrations, often below 10 ppm, to avoid any potential bitterness or astringency.

Stability considerations include its sensitivity to heat and pH, which can lead to degradation and loss of efficacy in flavor systems.

5. Use in Fragrances

Ampelopsin D is not a primary component in fragrance formulations. Its role, if used, would be as a trace component contributing to the overall complexity and stability of the fragrance. It does not have a significant impact on volatility or the top/middle/base note structure of fragrances.

6. Regulatory Status (Regional Overview)

United States: Not specifically listed under FEMA GRAS; usage would be subject to general safety evaluations.
European Union: Not explicitly listed under Regulation (EC) No 1334/2008; considered under general flavoring regulations.
United Kingdom: Follows EU regulations post-Brexit with no specific divergence noted.
Asia: Limited specific regulatory information; generally follows international safety assessments.
Latin America: Not specifically regulated; usage would be based on general safety and compliance with local regulations.

Citation hooks: FEMA; EFSA; national authority publications

7. Toxicology, Safety & Exposure Considerations

Ampelopsin D is generally considered safe at low exposure levels typical of its use in food and fragrance applications.

Oral Exposure: No specific ADI or MSDI established; considered safe based on traditional use and low concentrations.
Dermal Exposure: Limited data on irritation or sensitization; generally considered low risk due to its natural occurrence in plants.
Inhalation Exposure: Not typically a concern due to low volatility and usage levels.

Overall, the risk profile does not significantly differ between food and fragrance applications, assuming typical use levels.

8. Practical Insights for Formulators

Ampelopsin D is valued for its potential health benefits, particularly its antioxidant properties. It can synergize with other natural antioxidants to enhance product stability and shelf life. Formulators should be cautious of its potential to impart bitterness or astringency at higher concentrations. It is often under-utilized in formulations where its health benefits could be leveraged more effectively.

9. Confidence & Data Quality Notes

The data on ampelopsin D is well-established in terms of its chemical identity and natural occurrence. However, specific sensory and regulatory data are less documented, reflecting its secondary role in flavor and fragrance applications. Industry practices often rely on general safety assumptions due to the lack of specific regulatory guidance.

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.
