FlavScents AInsights Entry: Meyer Lemon Oil Cold Pressed (CAS: 1370641-98-7)

1. Identity & Chemical Information

• Common Name(s): Meyer Lemon Oil Cold Pressed
• CAS Number: 1370641-98-7
• FEMA Number: Not available
• Other Identifiers: Not available
• Material Type: Natural complex material derived from the cold pressing of Meyer lemons.
• Source: Citrus × meyeri, a hybrid citrus fruit native to China.

Meyer lemon oil is a natural complex material, not a single chemical compound. It is obtained through the cold pressing of the peel of Meyer lemons, which are known for their sweeter and less acidic flavor compared to regular lemons. The oil is characterized by a complex mixture of volatile compounds, primarily terpenes, which contribute to its unique sensory profile.

2. Sensory Profile

Meyer lemon oil is renowned for its fresh, sweet, and citrusy aroma with floral undertones. The oil's sensory profile is dominated by a bright, zesty lemon character with a hint of sweetness, making it a popular choice for both flavor and fragrance applications. It is often described as having a moderate to high intensity with excellent diffusion properties.

The oil serves as an impact note in formulations, providing a vibrant and uplifting citrus aroma that can enhance the overall sensory experience. While specific taste and odor thresholds are not well-documented, its potent aroma suggests a low threshold for sensory detection.

3. Natural Occurrence & Formation

Meyer lemon oil is naturally sourced from the peel of the Meyer lemon, a citrus fruit that is a cross between a citron and a mandarin/pomelo hybrid. The oil is extracted through cold pressing, a mechanical process that preserves the delicate aromatic compounds.

The oil's composition and sensory characteristics qualify it for use in products labeled as "natural flavor" or "natural fragrance," aligning with consumer preferences for natural ingredients.

4. Use in Flavors

Meyer lemon oil is widely used in the flavor industry, particularly in applications requiring a natural citrus note. It is commonly found in beverages, confectionery, baked goods, and dairy products. The oil acts as a flavor enhancer, providing a fresh and authentic lemon taste.

Typical use levels in finished food products range from 5 to 50 ppm, depending on the desired intensity and the specific application. The oil is generally stable under acidic conditions but may degrade under high heat or prolonged exposure to light and oxygen.

5. Use in Fragrances

In the fragrance industry, Meyer lemon oil is valued for its bright and uplifting citrus aroma. It is used across various fragrance families, including citrus, floral, and gourmand. The oil serves as a top note, providing an initial burst of freshness and enhancing the overall fragrance profile.

Typical concentration ranges in fragrance formulations vary, but it is often used at levels of 0.1% to 1% in the final product. Its volatility makes it an excellent choice for top note applications, contributing to the fragrance's initial impact.

5a. Key Constituents (Typical)

• Limonene: 60-70%
• Gamma-terpinene: 10-15%
• Beta-pinene: 5-10%
• Citral: 2-5%

The composition of Meyer lemon oil can vary based on factors such as geographic origin, harvest time, and processing methods. These constituents are primarily responsible for the oil's characteristic aroma and flavor.

7. Toxicology, Safety & Exposure Considerations

Meyer lemon oil is considered safe for use in both food and fragrance applications when used within recommended levels.

• Oral Exposure: No specific ADI or MSDI established, but generally recognized as safe at typical use levels.
• Dermal Exposure: Non-irritating and non-sensitizing at typical fragrance concentrations. IFRA standards should be consulted for specific product types.
• Inhalation Exposure: Low risk due to volatility and typical use concentrations. Occupational exposure should be managed with standard ventilation practices.

8. Practical Insights for Formulators

Meyer lemon oil is prized for its ability to impart a natural and authentic citrus note. It synergizes well with other citrus and floral ingredients, enhancing the overall complexity of the formulation. Formulators should be mindful of its volatility and potential for oxidation, which can be mitigated by using antioxidants and proper storage conditions.

Common pitfalls include overuse, which can lead to an overpowering aroma, and underuse, which may result in a lack of desired impact. Balancing its intensity with other ingredients is key to achieving the desired sensory profile.

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.
