2. Sensory Profile

Hydroxy-alpha-sanshool is renowned for its distinctive tingling and numbing sensation, often compared to the effect of carbonated beverages but more intense. This sensation is primarily due to its interaction with trigeminal nerve endings. The compound has a mild, peppery aroma with a slight citrus undertone. The taste threshold is not clearly reported, but its impact is significant even at low concentrations, making it an effective impact note in formulations.

3. Natural Occurrence & Formation

Hydroxy-alpha-sanshool is naturally found in the pericarp of Sichuan pepper (Zanthoxylum species), a spice commonly used in Asian cuisine. It is formed through enzymatic processes within the plant. Its presence in Sichuan pepper contributes to the spice's characteristic numbing and tingling sensation, which is a hallmark of many traditional dishes. This compound is often used to achieve a "natural flavor" designation in products aiming to replicate the unique sensory experience of Sichuan pepper.

4. Use in Flavors

Hydroxy-alpha-sanshool is primarily used in savory flavor applications, particularly in Asian-inspired dishes and snacks. It serves as an impact note, providing a unique tingling sensation that enhances the overall sensory experience. Typical use levels in finished food products range from 0.5 to 5 ppm, with higher concentrations used in products where a pronounced tingling effect is desired. The compound is relatively stable under typical cooking conditions but may degrade under prolonged exposure to high heat or acidic environments.

5. Use in Fragrances

In fragrance applications, hydroxy-alpha-sanshool is used to impart a fresh, tingling sensation, adding a unique dimension to personal care products and perfumes. It is often used in trace amounts to enhance the realism of citrus and spicy notes. The compound contributes primarily to the top and middle notes due to its moderate volatility. Typical concentrations in fragrance formulations are qualitative, as its primary role is to modify the sensory experience rather than contribute a distinct aroma.

6. Regulatory Status (Regional Overview)

United States: Hydroxy-alpha-sanshool is not explicitly listed as GRAS by FEMA, but its use in food is generally accepted based on historical use and safety data.
European Union: Not specifically listed under Regulation (EC) No 1334/2008; however, its use in food is permitted under general flavoring guidelines.
United Kingdom: Follows EU regulations post-Brexit with no significant divergence reported.
Asia: Widely used in traditional cuisines; specific regulatory status varies by country.
Latin America: Limited specific data available; generally follows international guidelines.

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: Hydroxy-alpha-sanshool is considered safe for consumption at typical use levels in food. No specific ADI or MSDI has been established, but its historical use suggests a wide margin of safety.
Dermal Exposure: In fragrance applications, it is not known to cause irritation or sensitization at typical use levels. IFRA guidelines should be consulted for specific product types.
Inhalation Exposure: The compound's volatility is moderate, and it poses minimal risk in occupational settings when used in standard concentrations.

Overall, the risk profiles for food and fragrance applications are similar, with no significant safety concerns reported at typical use levels.

8. Practical Insights for Formulators

Hydroxy-alpha-sanshool is valued for its ability to create a unique sensory experience, making it a popular choice in both culinary and fragrance applications. It synergizes well with citrus and spicy notes, enhancing their impact. Formulators should be cautious of overuse, as excessive concentrations can overwhelm other sensory elements. It is often under-utilized in non-Asian cuisines, where its potential to add a novel sensory dimension is not fully explored.

9. Confidence & Data Quality Notes

The data on hydroxy-alpha-sanshool is well-established in terms of its sensory properties and natural occurrence. However, specific regulatory and toxicological data are less comprehensive, relying on historical use and general safety assessments. Industry practices are well-documented, but some undocumented practices may exist due to regional variations in use.

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.
