FlavScents AInsights Entry: Lactuca Serriola Leaf Extract (CAS: 90046-10-9)

1. Identity & Chemical Information

Common Name(s): Lactuca serriola leaf extract, Prickly lettuce extract
CAS Number: 90046-10-9
FEMA Number: Not applicable
Other Identifiers: Not applicable
Material Type: Natural complex material derived from the leaves of Lactuca serriola, commonly known as prickly lettuce.
Source: The extract is obtained from the leaves of the Lactuca serriola plant, which is native to Europe and Asia but now found worldwide.
Key Constituents: The extract typically contains lactucin, lactucopicrin, and other sesquiterpene lactones, which contribute to its characteristic properties. Composition may vary based on origin, harvest, and processing methods.

2. Sensory Profile

Odor and Flavor Descriptors: The extract has a mild, slightly bitter taste with a green, leafy odor. It is often described as having a subtle, earthy aroma with hints of bitterness.
Taste and/or Odor Thresholds: Not clearly reported.
Typical Sensory Role: It is primarily used as a background realism note in flavor formulations, providing a natural, leafy character.

Citation hooks: FlavScents; peer-reviewed sensory literature

3. Natural Occurrence & Formation

Known Natural Sources: Lactuca serriola is the primary natural source, commonly found in temperate regions.
Formation Pathways: The extract is obtained through solvent extraction or steam distillation of the leaves, capturing the volatile and non-volatile components.
Relevance to “Natural Flavor” or “Natural Fragrance” Designation: As a plant-derived extract, it qualifies for natural flavor and fragrance designations under various regulatory frameworks.

7. Toxicology, Safety & Exposure Considerations

Oral Exposure: No specific ADI or MSDI established; generally considered safe at typical flavor use levels.
Dermal Exposure: Limited data on irritation or sensitization; generally regarded as safe in fragrance applications at typical use levels.
Inhalation Exposure: No specific occupational exposure limits; volatility is low, minimizing inhalation risk.
Risk Profiles: No significant differences in risk profiles between food and fragrance applications.

8. Practical Insights for Formulators

Value: Provides a natural, leafy character that enhances the authenticity of herbal and green profiles.
Typical Synergies: Pairs well with other herbal and green notes, such as mint and basil.
Common Formulation Pitfalls: Overuse can lead to excessive bitterness; balance with sweeter or more floral notes.
Frequent Over- or Under-Use: Often under-used due to its subtlety; careful balancing is required to achieve the desired effect.

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.
