CAS: 977038-65-5 FLAVORING AGENT OR ADJUVANT

Clover tops, red, extract solid (Trifolium pratense L.) is a botanical-derived flavoring agent or adjuvant prepared from the aerial tops of the red clover plant, used for its characteristic botanical flavor in food products.

What It Is

CLOVER TOPS, RED, EXTRACT SOLID (Trifolium pratense L.) is a botanical-derived natural extract prepared from the tops of the red clover plant. It is a plant extract used as a flavoring agent or adjuvant in food, imparting characteristic botanical, mild and slightly herbaceous notes that can complement other flavors in a wide range of formulations. This ingredient is known under several other names, including Clover Top Extract, Solid Red Trifolium Pratense Extract, and Solid Red Clover Top Extract Solid, reflecting its form and source. The red clover plant (Trifolium pratense L.) is a perennial leguminous plant broadly distributed in temperate regions and historically cultivated for forage and botanical uses. Extracts from its aerial parts have been adopted in flavor and fragrance contexts due to their aromatic profile. In the context of food formulation, this extract is classified as a flavoring agent or adjuvant, meaning it contributes primarily to sensory properties rather than nutritional value. Regulatory listings such as CFR reference 182.20 align this type of substance with natural extractives that are generally recognized for flavor use under certain regulatory frameworks. The physical form of the extract is typically a dry powder or solid, making it suitable for incorporation into dry mixes or liquid products following appropriate solubilization. Other botanical extracts share this general classification, but the term "Clover Tops, Red, Extract Solid" specifically refers to the extract derived from the flowering tops and upper stems of Trifolium pratense L. The identity of the ingredient is based on its plant source and processing form, and it is used for flavor enhancement rather than as a primary food component.

How It Is Made

The production of CLOVER TOPS, RED, EXTRACT SOLID begins with the harvesting of Trifolium pratense L. aerial parts—typically the flowering tops and leaves. After harvest, plant material is dried under controlled conditions to reduce moisture and preserve aromatic compounds. The dried botanical is then subjected to extraction using food-grade solvents or solvent-free techniques to isolate the soluble flavor constituents. Solvent extraction may involve ethanol, water, or other permitted food-compatible solvents to draw out essential oils and aromatic compounds from the plant matrix. Following extraction, the solvent-rich extract is concentrated under reduced pressure to remove volatile solvents, yielding a concentrated botanical extract. The concentrated extract may be further processed to achieve a solid form, often by adsorbing the liquid extract onto carriers such as maltodextrin or similar agents followed by spray-drying or vacuum-drying. The result is a dry, free-flowing powder that retains the characteristic aromatic profile of the original plant material. This solid form enhances stability and ease of handling in manufacturing environments. Manufacturers typically adhere to good manufacturing practices (GMP) and food-grade specifications when producing botanical extracts for flavor use to ensure purity and safety. Quality control tests may include microbial limits, residual solvent analysis, and sensory evaluation to confirm that the extract meets intended technical function criteria. The resulting extract solid is then packaged under controlled conditions to maintain product integrity until use in food applications.

Why It Is Used In Food

Clover tops, red, extract solid is used in food primarily for its function as a flavoring agent or adjuvant. In food science, flavoring agents are incorporated to enhance, modify, or balance the sensory characteristics of a product. Natural botanical extracts like this one offer complex aromatic profiles that can provide subtle botanical notes, adding depth and nuance to the overall flavor formulation. Their use is driven by both sensory and marketing considerations, as clean-label and plant-derived ingredients continue to be of interest in contemporary product development. Flavoring agents such as this extract are not intended to deliver nutrition but rather to influence aroma and taste perception. They are commonly used in conjunction with other ingredients to create a desired flavor profile in products such as beverages, confections, sauces, and savory seasonings. In some cases, they can help mask off-notes from other components or enhance the perception of key flavor notes. Their role as adjuvants may also support flavor stability over shelf life. The botanical origin of red clover extract aligns with current trends in food formulation that favor natural, plant-based components. While the specific sensory contribution of the extract varies by concentration and matrix, its inclusion is typically driven by the need to achieve consistent flavor delivery and to meet consumer expectations for natural flavorings. Additionally, such extracts allow formulators to achieve nuanced flavor effects that might be challenging with synthetic substitutes alone.

Adi Example Calculation

To illustrate how an acceptable daily intake (ADI) could be used in exposure assessment for a hypothetical flavoring agent, consider the following example. Suppose an ADI for a flavoring substance was established at a value of 10 mg per kilogram of body weight per day by a regulatory expert committee. For a person weighing 70 kilograms, this theoretical ADI would correspond to a safety threshold of 700 mg per day. If that substance were used at typical flavoring levels in food products, cumulative daily intake would be compared against the 700 mg benchmark to evaluate whether it stays well below the ADI. It is important to emphasize that this example uses hypothetical numbers for illustrative purposes and does not reflect an official ADI for CLOVER TOPS, RED, EXTRACT SOLID. Actual use levels of botanical flavoring agents are generally much lower than illustrative ADI thresholds and are informed by sensory requirements rather than nutritional contribution. This example simply demonstrates the concept of ADI and its application to exposure assessment in a generalized context.

Safety And Health Research

Safety assessments for botanical extracts like CLOVER TOPS, RED, EXTRACT SOLID consider compositional characteristics, intended use levels, and toxicological data relevant to consumer exposure. Regulatory bodies such as FEMA and JECFA evaluate flavoring agents to determine whether there are safety concerns at expected intake levels based on typical use. The inclusion of the ingredient in inventories such as the FDA’s Substances Added to Food reflects review processes that consider expert evaluations of safety within the context of intended flavor use. Toxicological data for specific botanical extracts are often limited relative to extensively studied single-compound additives, and safety assessments emphasize good manufacturing practices and compositional characterization to mitigate potential impurities. For plant-derived extracts, factors such as residual solvents, contaminant levels, and consistent production methods are part of safety evaluations. While individual studies on the physiological effects of red clover plant constituents have been conducted in other research contexts, these are not directly applicable to the regulatory safety assessment for food flavoring use unless incorporated in an authoritative evaluation by bodies such as JECFA. Overall, the safety profile of such botanical flavoring agents is considered within the framework of their intended use levels in food, which are typically low. Where comprehensive data are unavailable, regulatory-style guidance focuses on ensuring that flavoring agents are used at levels that do not pose safety concerns based on available evidence and professional expert judgment.

Regulatory Status Worldwide

In the United States, CLOVER TOPS, RED, EXTRACT SOLID is listed in the FDA’s "Substances Added to Food" inventory, previously known as EAFUS, which catalogs substances reported for use as food ingredients including flavoring agents evaluated by the Flavor and Extract Manufacturers Association (FEMA) and other expert bodies. This listing reflects recognition of the ingredient’s use in food under generally recognized conditions for flavor, but does not on its own constitute a specific FDA additive regulation beyond its inclusion in the GRAS/inventory framework. The CFR reference 182.20 is a section of the "Substances Generally Recognized as Safe" listings for essential oils, oleoresins, and natural extractives that are regarded as safe for their intended use when used in accordance with good manufacturing practice; however, the specific ingredient may not be itemized in that table itself but is aligned with the general category. Internationally, regulatory recognition for botanical extracts used as flavoring agents varies by country and region. National food standards and food additive lists often include broad categories for natural flavoring extracts, and specific ingredient acceptance is informed by national regulatory evaluations and usage history. Bodies such as JECFA provide expert evaluation of flavoring substances and publish specifications and safety assessments for many flavoring agents, although detailed JECFA specification entries for this specific extract may not be readily available in public databases. Regulatory frameworks typically rely on established safety evaluation processes for flavoring agents and may require manufacturers to substantiate the purity and safety of specific extracts as part of product dossiers, especially for novel ingredients in certain markets. Continued compliance with local regulations and monitoring of updates to additive inventories is important for manufacturers using this extract in global food products.

Taste And Functional Properties

The sensory profile of CLOVER TOPS, RED, EXTRACT SOLID reflects the botanical character of red clover. Although specific sensory descriptors vary by extract batch and processing method, such botanical extracts generally offer mild, herbaceous, and slightly floral or green notes that can complement both sweet and savory applications. These flavor cues tend to be delicate rather than overpowering, and they are often used in low concentrations to avoid dominance over other flavor components. In functional terms, the extract’s solubility and stability are relevant factors for formulators. As a solid botanical extract, it can be incorporated into dry mixes or pre-dissolved into liquid bases with adequate mixing. Solubility may vary depending on the carrier used in the drying process, but typical usage involves dispersion in aqueous or emulsion systems. Stability under heat and pH will depend on formulation conditions; botanical extracts can be sensitive to prolonged high-temperature processing, and formulators often evaluate thermal tolerance during product development. The flavor impact of such extracts may also interact with other sensory dimensions, such as bitterness or astringency, which should be balanced in the overall product matrix. While the primary functional property is sensory, the extract does not contribute significant nutritional value. Instead, its role is to influence perception and enhance the complexity of flavor profiles in a controlled manner.

Acceptable Daily Intake Explained

An acceptable daily intake (ADI) is a risk assessment concept used by regulatory and scientific bodies to estimate the amount of a substance that can be consumed daily over a lifetime without appreciable health risk. It is usually expressed in milligrams of the substance per kilogram of body weight per day and is based on toxicological data including animal studies and human data when available. ADIs are established by expert committees such as JECFA following systematic review of available evidence. For many botanical flavoring agents like CLOVER TOPS, RED, EXTRACT SOLID, detailed ADI values may not be explicitly established in public regulatory documentation. In such cases, caution is exercised by food manufacturers and regulators who rely on established safety evaluations of similar flavoring ingredients and usage history. The concept of ADI helps contextualize risk by providing a benchmark for exposure in relation to body weight, but it is important to note that ADIs are not recommended intake levels or nutritional targets—they are safety guidance values. Because flavoring agents are used in relatively low concentrations to achieve sensory effects, actual dietary exposure is usually far below levels of toxicological concern. Nonetheless, the ADI framework remains foundational to safety assessment, and explicit ADI values are applied where available from authoritative evaluations.

Comparison With Similar Additives

Clover tops, red, extract solid shares its functional role with other botanical and plant-derived flavoring agents used in food formulation. For example, natural extracts like rosemary extract and citrus peel extract are used to contribute herbal or citrus notes to beverage and savory products. Like red clover extract, these botanical extracts provide complex sensory profiles that synthetic single-compound flavorings may not achieve on their own. Their use levels are guided by flavor impact and compatibility with other ingredients. Compared to standard spice-derived flavorings such as basil or thyme extract, which offer distinct aromatic signatures, clover tops extract delivers subtler herbaceous cues and may be chosen particularly where a gentle botanical nuance is desired. In contrast, strong spice extracts can dominate the flavor profile if used at similar levels. Additionally, some botanical extracts such as vanilla extract provide sweet aromatic notes, whereas clover tops extract contributes green or herbaceous character. In regulatory and safety contexts, all such botanical flavoring agents are evaluated within broader categories of natural extractives, with safety and usage considerations informed by their compositional complexity and intended sensory effect rather than by singular active compounds alone. This comparison highlights that while technical function may be similar, sensory characteristics and compatibility with different food matrices distinguish one botanical flavoring agent from another.
