What is Beta-caryophyllene Alcohol?
Beta-caryophyllene alcohol (CAS Number: 472-97-9) is an organic compound classified as a sesquiterpene alcohol. It is structurally related to beta-caryophyllene, a naturally occurring volatile compound found in many plants including black pepper, cloves, hops, and cannabis. The alcohol form is used in food manufacturing as a flavoring agent and flavor adjuvant, contributing to the sensory profile of finished food products.
Common Uses
Beta-caryophyllene alcohol is utilized in the food industry primarily as a flavoring component in beverages, baked goods, confectionery, and savory products. Its spicy and woody flavor characteristics make it useful in formulations seeking to replicate pepper, clove, or herbal notes without using whole spices. The compound may also appear in seasonings, sauces, and processed foods where complex flavor development is desired. As with many synthetic flavoring agents, it is typically used in very small concentrations, measured in parts per million (ppm).
Safety Assessment
Beta-caryophyllene alcohol has not been formally evaluated and approved by the FDA as a Generally Recognized As Safe (GRAS) ingredient. However, the FDA database contains zero reported adverse events associated with this additive, and no product recalls have been attributed to it. The absence of negative regulatory actions and reported health incidents suggests a benign safety profile in current food applications, though limited public toxicological data is available.
Given its structural relationship to beta-caryophyllene—a compound with a long history of consumption in foods and studied for various biological properties—the alcohol derivative is unlikely to present significant safety concerns at typical food use levels. However, the lack of formal GRAS status means manufacturers using this ingredient should rely on existing food additive regulations or petition for formal FDA approval if required in specific applications.
Regulatory Status
Beta-caryophyllene alcohol is not listed as a GRAS substance by the FDA, meaning it does not have blanket approval for use in all food categories. Its regulatory pathway in the United States requires either compliance with food additive regulations (21 CFR Part 180) or demonstration of prior sanctioned use. Different jurisdictions may have varying approval statuses; the European Food Safety Authority (EFSA) maintains its own evaluation standards for flavoring agents.
Manufacturers wishing to use this ingredient must ensure compliance with local regulations in their target markets. Some jurisdictions may allow it under existing flavor regulations if it has been previously used in food, while others may require additional documentation or premarket approval.
Key Studies
Limited peer-reviewed research specifically addresses beta-caryophyllene alcohol as a food additive. Most scientific literature focuses on the parent compound, beta-caryophyllene, which has been studied for its flavor properties and potential biological activities. Studies on beta-caryophyllene indicate it is rapidly metabolized and does not bioaccumulate in tissues.
The structural similarity between beta-caryophyllene alcohol and its precursor suggests comparable metabolic pathways, though direct toxicological studies on the alcohol form are not widely published in open scientific literature. The absence of adverse event reports after years of potential use in food applications provides some reassurance regarding safety at intended levels of consumption.
