7. Toxicology, Safety & Exposure Considerations

• Oral Exposure: Generally considered safe when consumed as part of food; no specific ADI established.
• Dermal Exposure: Low risk of irritation or sensitization; not typically used in high concentrations.
• Inhalation Exposure: Minimal risk due to low volatility; occupational exposure is not a significant concern.

Risk profiles are similar for both food and fragrance applications, with no significant safety concerns reported.

8. Practical Insights for Formulators

Luteum ovi extract is valued for its ability to enhance richness and depth in both flavors and fragrances. It synergizes well with other savory and umami notes. Formulators should be cautious of overuse, which can lead to an overpowering sulfurous note. It is often underutilized in sweet applications where it can add unexpected complexity.

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.
