CAS: 8007-75-8 FLAVORING AGENT OR ADJUVANT

Bergamot oil is a citrus-derived essential oil used as a flavoring agent in foods and beverages. It is included in the FDA inventory of substances added to food and has a FEMA GRAS reference, with regulatory context in 21 CFR 182.20. Bergamot oil’s sensory profile is citrusy and aromatic.

What It Is

Bergamot oil, formally known as BERGAMOT, OIL (CITRUS AURANTIUM L. SUBSP. BERGAMIA WRIGHT ET ARN.), is an essential oil extracted from the rind of the bergamot orange fruit. Its primary identification comes from the botanical source Citrus aurantium subspecies bergamia, and it is characterized by the CAS number 8007-75-8. Bergamot oil functions in food systems as a flavoring agent or adjuvant, meaning it is used to impart or modify flavor in foods, beverages, and flavor preparations. It is recognized for its citrus-like aroma and taste, often described as a blend of sweet orange with a light floral note. This ingredient is classified under flavoring agents due to its sensory impact, contributing aromatic and taste properties rather than nutritional value. Bergamot oil is complex in composition, composed of a mixture of volatile organic compounds including monoterpenes and esters that contribute to its unique flavor characteristics. In food contexts, it is used at low levels to enhance aroma and flavor profiles rather than as a primary ingredient. The ingredient appears in regulatory inventories such as the FDA Substances Added to Food inventory, indicating that it has been reviewed for use in food applications. Within classifications of flavoring substances, bergamot oil’s inclusion reflects its historical and ongoing use as a flavor ingredient, particularly in products where citrus flavor profiles are desired.

How It Is Made

The production of bergamot oil begins with the harvest of ripe bergamot oranges, typically grown in Mediterranean climates. The essential oil is derived from the peel of the fruit, where volatile aromatic compounds are most concentrated. Traditional extraction methods involve cold-pressing the citrus peel to release the oil, a process that has historical roots in artisanal citrus oil production. More modern industrial methods may use mechanical peelers and centrifugation to separate oil from water and plant solids efficiently. Once extracted, the crude oil may undergo clarification or rectification processes to remove unwanted fractions or reduce levels of specific components, such as furocoumarins, which are known to impart phototoxic properties in non-food uses. These refining steps are designed to produce a product that meets applicable food-grade quality standards and sensory specifications. The resulting bergamot oil is a complex mixture of natural compounds. Because it is a botanical extract rather than a pure chemical substance, its composition can vary based on factors such as plant variety, growing conditions, and extraction method. Quality control in production focuses on achieving a consistent flavor and aromatic profile suitable for flavor formulation. Specifications for food-grade bergamot oil typically address sensory characteristics, purity, and absence of contaminants that could impact safety or quality.

Why It Is Used In Food

Bergamot oil is used in food primarily for its distinctive citrus flavor and aroma, which can enhance the sensory appeal of a variety of products. Flavoring agents like bergamot oil are added to foods and beverages to provide characteristic sensory experiences that would be difficult to achieve with base ingredients alone. In the case of bergamot oil, its citrusy and slightly floral notes make it a desirable addition for flavor profiles that aim to evoke fresh citrus characteristics. Food technologists incorporate bergamot oil into flavor formulations because it can complement and round out the taste of citrus-based products, beverages, confections, and baked goods. Its use allows manufacturers to create nuanced flavors that resonate with consumer expectations for citrus tastes without relying solely on sugar or artificial flavor profiles. Beyond sensory function, bergamot oil can contribute to the overall flavor complexity of a product. In beverage applications such as teas and soft drinks, its aromatic profile can provide depth and freshness, appealing to consumers who seek flavorful and natural tasting products. Since bergamot oil is a concentrated flavoring agent, only small amounts are needed to achieve the desired effect, which makes it efficient in formulation.

Adi Example Calculation

When a formal ADI is not explicitly established, illustrating exposure scenarios can help contextualize safety. For example, if a flavoring ingredient like bergamot oil were used at a level of 1 milligram per kilogram of food, a person consuming 1 kilogram of flavored food in a day would be exposed to approximately 1 milligram of the ingredient. Compared to typical flavor usage levels, which are often far lower, this scenario would represent a conservative exposure estimate for illustrative purposes. Such calculations do not reflect specific regulatory numeric ADIs but demonstrate how exposure estimates relate to typical use levels. Consider a hypothetical adult weighing 70 kilograms consuming flavored foods containing 1 milligram per kilogram of bergamot oil: the exposure per kilogram body weight would be 1/70 milligram per kilogram of body weight per day. This illustrative calculation helps contextualize how low usage levels in foods translate to consumer exposure. These examples underscore that the safety evaluation for ingredients like bergamot oil is grounded in typical use levels and expert review of chemical composition rather than a formal numeric ADI. Consumers encounter flavors at levels that are orders of magnitude lower than exposures that would raise safety concerns, according to regulatory assessments.

Safety And Health Research

Food-grade bergamot oil has been the subject of safety evaluations focused primarily on its use as a flavoring ingredient at low levels typical of food products. Scientific evaluations consider the toxicological profile of the essential oil compounds and their constituents. As a naturally derived complex mixture, bergamot oil includes volatile components that have been studied for sensory and safety characteristics in foods. Regulatory assessments underlying FEMA GRAS determinations for citrus-derived flavoring substances consider the chemical composition and exposure levels associated with intended use. These evaluations review available toxicological data on constituent groups and apply conservative safety thresholds to ensure that use as a flavoring agent does not pose safety concerns under normal conditions of use. The FEMA Expert Panel’s GRAS assessment reflects a comprehensive review of the scientific literature and chemical characterization relevant to bergamot oil’s safety as a flavoring ingredient, supporting its use at levels consistent with good manufacturing practices. (FEMA)(FEMA) Scientific research outside regulatory assessment contexts has explored components of bergamot oil for various biological activities, often at levels much higher than those encountered in food flavoring applications. However, such research does not directly translate to food safety considerations because the exposure levels and contexts differ greatly. Regulatory safety assessments focus on the risk associated with typical dietary exposure and integrate available toxicological data to determine whether risks are plausible at those exposure levels. Overall, current regulatory evaluations support the safety of bergamot oil when used as intended in food flavoring applications. Continued research into essential oil constituents contributes to broader understanding, but regulatory status is grounded in evidence of safe use at typical food-relevant levels.

Regulatory Status Worldwide

In the United States, bergamot oil is listed in the FDA’s Substances Added to Food inventory with reference to 21 CFR 182.20, which covers essential oils, oleoresins, and natural extractives used as flavoring substances. This indicates that bergamot oil has been reviewed within the context of the FDA’s flavoring regulations and is recognized as a flavoring ingredient under those provisions. The inclusion in this regulatory inventory supports its use in food systems when used in accordance with good manufacturing practices and appropriate use levels. Evidence of this regulatory status is indicated by the FDA inventory listing and the associated Code of Federal Regulations reference. (FEMA)(FEMA) Additionally, the Flavor and Extract Manufacturers Association (FEMA) has assigned a FEMA GRAS (Generally Recognized as Safe) reference number to bergamot oil (FEMA 2153), indicating that an expert panel has assessed it for safety under its intended conditions of use as a flavor ingredient. While FEMA GRAS status involves independent scientific evaluation, its presence in the FDA inventory indicates regulatory recognition in the U.S. for flavor use. (FEMA)(FEMA) Regulatory frameworks outside the U.S. may not assign specific E-numbers to bergamot oil, and its use will depend on local food additive regulations. In some jurisdictions, essential oils like bergamot oil are treated as natural flavorings subject to general flavoring provisions rather than enumerated additive lists. Because regulatory approaches vary globally, formulators must consult local food additive regulations to confirm allowable use conditions.

Taste And Functional Properties

Bergamot oil is noted for its unique citrus flavor profile, which combines bright, fresh citrus notes with subtle floral and fruity undertones. This flavor is derived from its chemical composition, which includes a range of natural volatile compounds. In sensory terms, bergamot oil’s aroma and taste are often associated with well-known citrus flavors, making it valuable in products where a refreshing, citrus-forward experience is desired. Functionally, bergamot oil is a volatile oil that disperses easily in food formulations when combined with suitable carriers or emulsifiers. Its solubility characteristics mean it integrates well with lipid-based carriers and alcohol solutions commonly used in flavor technology. Because it is potent, it is used in very small quantities to achieve the desired sensory impact. The stability of bergamot oil’s flavor and aromatic properties depends on formulation and processing conditions. Heat and prolonged exposure to air can alter its sensory attributes, so formulators must consider processing parameters to retain its sensory integrity. In applications such as beverages or confections, where processing temperatures are controlled, bergamot oil can contribute consistent flavor notes without overpowering other components.

Acceptable Daily Intake Explained

Acceptable Daily Intake (ADI) is a concept used in food safety to describe the amount of a substance that can be consumed daily over a lifetime without appreciable health risk. For flavoring agents like bergamot oil, ADI values are not always formally established as numeric limits because regulatory frameworks such as FEMA GRAS evaluate safety based on conditions of intended use rather than setting a specific numeric ADI. In regulatory evaluations, safety is assessed by expert panels that consider chemical composition, typical use levels, and toxicological data for components. When a substance is determined to be generally recognized as safe under its intended conditions of use, it implies that experts have concluded that exposure through consumption of flavored foods at typical use levels does not present safety concerns. As such, numeric ADI values may not be applicable or explicitly defined for all flavoring agents. For consumers and formulators, understanding that a substance’s regulatory approval reflects an evaluation of safety at normal use levels is key. ADI concepts help regulators frame safety assessments, but for complex natural flavorings such as bergamot oil, decisions are often based on comprehensive reviews of chemical profiles and exposure estimates rather than a single numeric intake value. This approach ensures that safety assessments are tailored to how the ingredient is actually used in food products.

Comparison With Similar Additives

Bergamot oil can be compared with other citrus-derived flavoring agents, such as orange oil and lemon oil, which are also essential oils used to impart citrus character in foods. Like bergamot oil, these oils provide volatile citrus notes that enhance flavor profiles. Orange oil typically has a sweeter, more familiar orange peel profile, while lemon oil imparts sharper, bright citrus notes. Bergamot oil’s profile is distinctive for its blend of citrus brightness and subtle floral undertones, making it suitable for products where a more nuanced citrus complexity is desired. Compared to isolated flavor compounds such as limonene, which is a single chemical compound contributing citrus aroma, whole essential oils like bergamot oil deliver a broader range of sensory cues due to their mixture of constituents. This complexity allows flavorists to design richer, layered flavor profiles that may be difficult to achieve with single compounds alone. Lemon oil and orange oil are similarly complex mixtures, but each has its own characteristic balance of terpenes and esters that distinguish it from bergamot oil. In formulation practice, these citrus-derived oils are selected based on the desired sensory outcome. Bergamot oil’s role is often complementary to other citrus flavorings, providing depth and balance. Flavor formulations may combine multiple citrus oils to achieve a targeted sensory profile, taking advantage of each oil’s unique functional properties.

Common Food Applications Narrative

In a range of consumer products, bergamot oil is used as a flavoring ingredient to enhance citrus profiles and provide aromatic depth. In beverages such as carbonated soft drinks, flavored sparkling waters, and ready-to-drink teas, bergamot oil contributes refreshing and recognizable citrus notes that align with consumer expectations for light, fruit-forward flavors. This aligns with its traditional use in certain tea blends where citrus flavor is a key sensory component. In confectionery and baked goods, bergamot oil can be used to add nuanced citrus characteristics that complement sweetness. In candies, gummies, and frostings, small amounts of bergamot oil can elevate the overall taste experience by introducing bright top notes that balance richer base flavors. Similarly, in ice creams and sorbets with citrus themes, bergamot oil’s aromatic qualities enhance the fruit-like sensory appeal. Flavor houses often incorporate bergamot oil into multi-component flavor systems designed for use in complex products such as flavored dairy desserts and low-alcohol beverages. In these contexts, bergamot oil is paired with other citrus-derived flavorings to create layered sensory profiles. Across these applications, the use of bergamot oil reflects its role as a concentrated flavoring agent that enhances product appeal by delivering distinctive sensory characteristics.
