FlavScents AInsights Entry for Citrus spp. Peels Extract (CAS: 94266-47-4)

1. Identity & Chemical Information

Citrus spp. peels extract, commonly referred to as citrus peel oil, is a natural complex material derived from the peels of various citrus fruits such as oranges, lemons, and grapefruits. It is not a single compound but a mixture of volatile compounds. The CAS number for this extract is 94266-47-4. It does not have a specific FEMA number due to its complex nature. Other identifiers include its use in IFRA standards and various food and fragrance regulations. The composition of citrus peel extracts can vary significantly depending on the citrus species, geographical origin, and extraction method used.

2. Sensory Profile

Citrus peel extracts are characterized by their fresh, zesty, and tangy aroma, often described as a bright and uplifting scent. The intensity of the odor can vary, but it is generally considered to be strong with high diffusion. The flavor profile is similarly fresh and tangy, contributing a lively citrus note to formulations. These extracts are typically used as impact notes in both flavors and fragrances, providing a sense of freshness and realism.

3. Natural Occurrence & Formation

Citrus peel extracts are naturally sourced from the peels of citrus fruits. The extraction process typically involves cold pressing or steam distillation, which preserves the volatile compounds responsible for the characteristic citrus aroma. These extracts are considered natural flavors and fragrances, aligning with consumer preferences for natural products. The formation of the extract involves the release of essential oils from the oil glands in the citrus peel.

4. Use in Flavors

Citrus peel extracts are widely used in flavor applications, particularly in beverages, confectionery, and baked goods. They serve as both primary flavor notes and modifiers, enhancing the overall flavor profile with their fresh and tangy characteristics. Typical use levels in finished products range from 10 to 100 ppm, depending on the desired intensity and product type. These extracts are generally stable under acidic conditions but may degrade under high heat or prolonged exposure to air.

5. Use in Fragrances

In the fragrance industry, citrus peel extracts are used across various fragrance families, including fresh, floral, and gourmand. They function as top notes, providing an initial burst of freshness and brightness. Typical concentration ranges in fragrance formulations are from 0.1% to 5%, depending on the desired impact. The volatility of these extracts makes them ideal for creating lively and invigorating scents.

6. Regulatory Status (Regional Overview)

In the United States, citrus peel extracts are generally recognized as safe (GRAS) for use in food and beverages. In the European Union, they are regulated under Regulation (EC) No 1334/2008 and have specific FL numbers. The United Kingdom follows similar regulations post-Brexit. In Asia, regulations vary, with Japan and China having specific guidelines for natural extracts. In Latin America, countries like Brazil and members of MERCOSUR have their own regulatory frameworks, often aligning with international standards.

7. Toxicology, Safety & Exposure Considerations

Citrus peel extracts are considered safe for oral exposure when used within recommended levels, with no specific ADI or MSDI established. Dermal exposure in fragrances is generally safe, though some individuals may experience irritation or sensitization, particularly with high concentrations. Inhalation exposure is typically low risk due to the volatility and rapid dispersion of the compounds. The risk profiles for food and fragrance applications are similar, with the primary concern being potential skin sensitization.

8. Practical Insights for Formulators

Citrus peel extracts are valued for their ability to impart a fresh and natural citrus note. They synergize well with other fruity and floral notes, enhancing the overall complexity of a formulation. Common pitfalls include overuse, which can lead to overpowering or harsh notes, and underuse, which may result in a lack of impact. Formulators should consider the variability in composition and adjust formulations accordingly.

9. Confidence & Data Quality Notes

The data on citrus peel extracts is well-established, with extensive documentation in both flavor and fragrance applications. Industry practices are well-documented, though some variability exists due to natural differences in raw materials. Regulatory ambiguities are minimal, with most regions providing clear guidelines for 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.
