FlavScents AInsights Entry for Quercitrin (CAS: 522-12-3)

1. Identity & Chemical Information

Quercitrin is a flavonoid glycoside commonly found in various plants. Its IUPAC name is 2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-3-[[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxy]-4H-chromen-4-one. The CAS number for quercitrin is 522-12-3. It does not have a FEMA number. Other identifiers include its molecular formula, C21H20O11, and a molecular weight of 448.38 g/mol. Quercitrin contains hydroxyl groups that contribute to its antioxidant properties, which are relevant to its odor and flavor characteristics.

2. Sensory Profile

Quercitrin is known for its mild, astringent taste and subtle odor profile. It is not typically used for its scent but can contribute to the overall flavor profile of a product by adding a slight bitterness and astringency. The taste threshold for quercitrin is not well-documented, but it is generally considered to have a low intensity. In flavor systems, it acts as a background modifier, enhancing the complexity of the flavor without being a dominant note.

3. Natural Occurrence & Formation

Quercitrin naturally occurs in various fruits, vegetables, and medicinal plants, including oak trees, buckwheat, and certain citrus fruits. It is formed through the glycosylation of quercetin, a process that occurs naturally in plants. Quercitrin's presence in natural sources makes it relevant for "natural flavor" designations, particularly in products emphasizing plant-based ingredients.

4. Use in Flavors

Quercitrin is used in flavor applications primarily for its ability to enhance the complexity of fruit and herbal flavors. It is commonly found in beverages, confectionery, and dietary supplements. Typical use levels in finished food products range from 10 to 100 ppm, depending on the desired intensity and the specific application. Quercitrin is relatively stable under normal processing conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

While quercitrin is not a primary fragrance material, it can be used in fragrance formulations to add a subtle, natural complexity. It is occasionally used in herbal and green fragrance families. Its role is typically as a trace modifier, contributing to the realism of the fragrance. Quercitrin is not volatile and does not contribute significantly to the top or middle notes of a fragrance.

6. Regulatory Status (Regional Overview)

In the United States, quercitrin is generally recognized as safe (GRAS) for use in food products. In the European Union, it is regulated under Regulation (EC) No 1334/2008 and is permitted for use in food flavorings. The United Kingdom follows similar regulations post-Brexit. In Asia, quercitrin is accepted in Japan and China for use in food products, though specific regulations may vary. In Latin America, countries like Brazil recognize quercitrin under MERCOSUR regulations.

7. Toxicology, Safety & Exposure Considerations

Quercitrin is considered safe for oral consumption at typical dietary levels, with no established acceptable daily intake (ADI) due to its low toxicity. Dermal exposure is generally safe, with no significant reports of irritation or sensitization, making it suitable for use in personal care products. Inhalation exposure is minimal due to its low volatility. Overall, quercitrin poses a low risk in both food and fragrance applications.

8. Practical Insights for Formulators

Quercitrin is valued for its ability to enhance the complexity and authenticity of fruit and herbal flavors. It synergizes well with other flavonoids and phenolic compounds. Formulators should be cautious of its potential to impart bitterness if used excessively. It is often underutilized in formulations where its subtle astringency could enhance the overall profile.

9. Confidence & Data Quality Notes

The data on quercitrin is well-established, with comprehensive studies supporting its safety and sensory characteristics. Industry practices are well-documented, though specific sensory thresholds are less frequently reported. Regulatory information is consistent across major regions, with no significant ambiguities.

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.
