What is Cis-3-octen-1-ol?
Cis-3-octen-1-ol (CAS Number: 20125-84-2) is an eight-carbon unsaturated alcohol belonging to the class of organic compounds known as alkenols. It exists in nature as a volatile component in various fruits and plants, contributing to their characteristic aromas. In food manufacturing, cis-3-octen-1-ol is synthesized chemically to serve as a flavoring agent, providing fresh, fruity, green, and herbaceous notes to food and beverage products.
Common Uses
Cis-3-octen-1-ol is used in the flavoring industry to enhance or create specific taste and aroma profiles in food products. It is typically employed in:
- Beverages, including juices, soft drinks, and alcoholic drinks
- Dairy products such as yogurts and flavored milks
- Confectionery and candy items
- Baked goods and desserts
- Savory snacks and seasonings
- Processed fruit products
The compound is used in very small quantities, as is typical for flavoring agents. Its presence in natural food sources suggests it can contribute to authentic fruit and plant-like sensory experiences in formulated products.
Safety Assessment
Cis-3-octen-1-ol has not received formal FDA GRAS (Generally Recognized As Safe) designation. However, the absence of GRAS status does not indicate the substance is unsafe; rather, it reflects that a formal petition for GRAS status has not been submitted or approved through FDA channels.
The safety profile available indicates:
- **No reported adverse events** to the FDA related to cis-3-octen-1-ol
- **No FDA recalls** associated with this additive
- **Presence in nature** suggests a history of safe consumption through natural food sources
The European Food Safety Authority (EFSA) evaluates flavoring substances through its flavoring panel. Assessment of structurally similar alkenols and the naturally occurring background of these compounds suggests a reasonable safety margin for use as a flavoring agent at typical application levels.
As with all flavoring agents, cis-3-octen-1-ol is used at levels far below those that would present toxicological concern. The concentration in food products is typically measured in parts per million (ppm).
Regulatory Status
In the United States, cis-3-octen-1-ol may be used as a flavoring agent under FDA regulations for indirect food additives (21 CFR 182.60) if it meets specifications for food-grade purity and is used in accordance with good manufacturing practices. However, it does not have specific GRAS affirmation or a direct food additive listing.
In the European Union, this substance may be evaluated under the Regulation (EC) No 1334/2008 on flavorings, which requires substances to undergo safety assessment before market authorization.
Manufacturers using cis-3-octen-1-ol must ensure the ingredient meets food-grade standards and declare it appropriately in product ingredient lists, typically under the blanket term "natural flavor" or "artificial flavor" depending on its source and regulatory jurisdiction.
Key Studies
While specific toxicological studies exclusively on cis-3-octen-1-ol are limited in public literature, the safety assessment of structurally related alkenols and volatile flavor compounds has been conducted by regulatory bodies. The EFSA Flavoring Panel has evaluated many structurally similar C8 alcohols and related compounds.
The naturally occurring presence of cis-3-octen-1-ol in fruits and botanical sources provides a history of safe exposure, supporting its use as a flavoring agent. The low application levels in food—typically less than 10 ppm in final products—further support safety margins.
Additional research through chemical analogs and read-across from closely related compounds indicates no significant toxicological concerns at food use levels.
