ADVANTAME

CAS: 714229-20-6 NON-NUTRITIVE SWEETENER

Advantame is a high intensity, non-nutritive sweetener used to provide sweet taste in foods and beverages without contributing calories and is regulated as a food additive in several jurisdictions.

What It Is

Advantame is a high-intensity, non-nutritive sweetener used in foods and beverages to provide potent sweetness without adding significant calories. Its CAS number is 714229-20-6, and it is defined chemically as N-[N-[3-(3-hydroxy-4-methoxyphenyl)propyl]-alpha-aspartyl]-L-phenylalanine 1-methyl ester, monohydrate as described in the United States Code of Federal Regulations for food additives §172.803. It belongs to the class of high intensity sweetening agents, which are structurally derived from amino acids and related compounds with functional groups that interact with sweet taste receptors. Advantame’s intense sweetness allows it to be used in very low concentrations compared to nutritive sugars, meaning only small amounts are needed to achieve desired sweetness in formulations. Advantame is part of a group of intensely sweet compounds developed to help food manufacturers reduce caloric content while maintaining palatability. It was designed to retain sweetness intensity orders of magnitude greater than sucrose, supporting its classification as a high-intensity sweetener. Regulatory frameworks in different regions recognize it as a sweetener and flavor enhancer in a range of food applications, subject to specifications and good manufacturing practices. This additive’s naming conventions include a set of systematic chemical descriptors reflecting its molecular structure. These other names represent synonyms used in technical and regulatory texts but generally refer to the same core compound that functions as a non-nutritive, high-intensity sweetener in food and beverage products.

How It Is Made

The production of advantame involves chemical synthesis processes developed to achieve high purity and specific structural characteristics that confer sweetening potency. In general, advantame is synthesized via selective chemical reactions that combine precursor molecules — including an aspartyl dipeptide derivative and a substituted benzaldehyde — under controlled laboratory conditions. Chemical steps may include catalytic hydrogenation and esterification to build the target compound, followed by purification processes such as crystallization and washing to remove unreacted precursors and byproducts. Analytical and quality control methods are applied to ensure the final product meets regulatory specifications, including assays for compound identity and purity. In the United States, the Food and Drug Administration (FDA) references methods described in the documentation incorporated in 21 CFR §172.803 to define acceptable specifications for advantame, which include limits on related substances and compositional criteria. These methods ensure that advantame used in food applications is consistent and meets safety criteria prior to use by food manufacturers. Manufacturers typically produce advantame in forms suitable for blending into dry or liquid food matrices, with processes designed to maintain stability and functional integrity during storage and distribution. Given its intense sweetness, production processes are optimized to deliver a highly concentrated and stable ingredient that can be used at low dosages in commercial products.

Why It Is Used In Food

Advantame serves as a high-intensity sweetener in food and beverage products, enabling manufacturers to formulate reduced-calorie, sugar-reduced, or sugar-free offerings without compromising sweetness. Its extremely high sweetness potency means that only minute quantities are needed to achieve desired levels of sweetness, which helps reduce the caloric contribution of sugars and other nutritive sweeteners in finished foods. Beyond calorie reduction, advantame allows product developers to tailor taste profiles, particularly in beverages, confectionery, desserts, and tabletop sweetening applications. It has functional utility in formulations where intense sweetness is desired without bulk, making it suitable for sugar-free beverages, powdered drink mixes, and other applications where sugar would ordinarily be used for sweetness but not for texture or bulk. Food manufacturers also incorporate advantame to respond to consumer interest in products that support calorie-conscious choices and flexibility in ingredient systems. While its use is governed by regulatory allowances and specifications, within those frameworks advantame provides an option for achieving sweetness with minimal addition levels and aligns with broader trends in food innovation for reduced caloric content.

Adi Example Calculation

To illustrate how an ADI might be applied in a theoretical context, one can consider a hypothetical adult body weight and the upper bound of an established acceptable daily intake. For example, using an ADI fixed by a regulatory body, if a hypothetical adult body weight is used as the basis, one could calculate the maximum daily intake by multiplying the ADI value by the body weight. This simple calculation helps illustrate the concept of an ADI as a lifetime safety benchmark rather than a target intake. It is important to recognize that actual intake from food products is dependent on both the amount of advantame present in each product and the frequency and quantity of consumption. Typical dietary patterns and use levels result in estimated exposures that are a small fraction of the ADI, reflecting conservative regulatory assessments that build safety margins into their determinations.

Safety And Health Research

Regulatory authorities and scientific bodies have reviewed toxicological and safety data on advantame as part of their evaluation before authorizing its use in food. These evaluations typically encompass studies on metabolism, toxicokinetics, genotoxicity, chronic and subchronic toxicity, reproductive and developmental toxicity, and human tolerability. For instance, the European Food Safety Authority’s scientific opinion concluded that available data did not raise concerns regarding genotoxicity or carcinogenicity and supported establishment of an ADI based on a no-observed-adverse-effect level from developmental toxicity studies. Safety assessments consider both animal and human data to characterize potential hazards and estimate relative exposure levels. Regulatory bodies such as JECFA and EFSA evaluate this evidence to inform acceptable use conditions and any restrictions. These reviews rely on established toxicological principles and standards of evidence to ensure that the additive’s inclusion in food aligns with consumer safety expectations. Because advantame is used in small amounts relative to nutritive sweeteners, exposure levels in most diet scenarios fall below thresholds considered protective when evaluated within regulatory risk assessment frameworks.

Regulatory Status Worldwide

Advantame is recognized under the United States food additive regulations at 21 CFR §172.803, which permits its safe use as a sweetening agent and flavor enhancer in foods generally, except in meat and poultry, under good manufacturing practices. This section of the Code of Federal Regulations provides the regulatory basis for its use in the United States and is consistent with the FDA’s amendment of the food additive regulations to include advantame following a successful food additive petition. In the European Union, advantame has been authorized as a food additive and assigned the E number E969 under Commission Regulation (EU) No 497/2014 based on a scientific opinion from the European Food Safety Authority (EFSA) that concluded it does not raise safety concerns at the proposed uses and levels. Internationally, advantame has been evaluated by bodies such as the Joint FAO/WHO Expert Committee on Food Additives (JECFA), which established an acceptable daily intake (ADI) for advantame as part of its evaluations. Various countries and regions reference these and other assessments when determining local regulatory status. Specifications, permitted uses, and conditions vary by jurisdiction, but the presence of advantame in official additive lists reflects broad regulatory acceptance within defined parameters of use.

Taste And Functional Properties

Advantame is formulated to deliver intense sweetness with minimal off-notes, enabling it to approximate the sensory experience of sugar in many food applications. Sensory evaluations during its development indicate that advantame has dominant sweet flavor characteristics with limited perceived bitter or sour notes compared to nutritive sugars, which makes it useful in products where clean sweetness is desired. Its high sweetness potency means that small quantities are sufficient, which can be beneficial in avoiding unwanted flavor contributions from additives themselves. Functionally, advantame exhibits properties such as stability under normal storage conditions, allowing it to retain sweetness over extended periods when used in suitable food matrices. Research has noted that advantame may exhibit some instability in highly acidic or thermally treated conditions, which can lead to degradation and formation of breakdown products; manufacturers consider these factors when formulating acidic beverages or heat-processed foods. The compound’s solubility and compatibility with other formulation ingredients influence its selection in different product categories. Its intense sweetening power and ability to blend with other sweeteners provide flexibility for balancing taste profiles, particularly in combination sweetener systems. Because advantame is used at very low concentrations relative to sucrose, its functional influence beyond sweetness is primarily limited to taste rather than bulking or textural roles. This focus on sensory contribution is typical for high-intensity sweeteners in food systems.

Acceptable Daily Intake Explained

An acceptable daily intake (ADI) is a safety benchmark established by scientific committees to estimate a daily exposure level that is unlikely to pose health concerns over a lifetime, based on toxicological data and uncertainty factors. In the case of advantame, JECFA established an ADI expressed as a range up to a specified upper level of milligrams per kilogram of body weight per day derived from controlled toxicology studies with uncertainty factors applied to account for variability across populations. This ADI does not represent a recommendation to consume the additive at that level, but rather a safety reference point for regulators and risk assessors. ADIs help ensure that even high consumers of foods containing the additive are unlikely to exceed exposure levels considered safe based on available evidence. Because usage levels of advantame in food products are typically very low due to its high sweetness potency, estimated exposures for most consumers are well below established ADIs.

Comparison With Similar Additives

Advantame is one of several high-intensity non-nutritive sweeteners used in reduced-calorie and sugar-free formulations. Others include aspartame, sucralose, acesulfame potassium, and neotame. Compared to sucrose, these sweeteners deliver much greater sweetness intensity per unit mass, enabling reduced usage levels. Aspartame has a long history of regulatory evaluation and use, though it contributes some calories and has specific considerations for individuals with phenylketonuria due to its phenylalanine component. Sucralose is another high-intensity sweetener with different chemical structure and sensory profile, often noted for its stability across a range of pH and temperature conditions. Acesulfame potassium is notable for its stability in heat-processed products. Neotame is structurally related to aspartame but designed to be significantly more potent. Each of these sweeteners has undergone its own safety evaluations by regulatory agencies, which inform permitted uses and conditions. While all serve the common function of providing intense sweetness, they differ in molecular structure, sensory attributes, thermal stability, and regulatory status across jurisdictions.

Common Food Applications Narrative

Advantame has a range of applications across many food and beverage categories where sweetness is needed without significant caloric contribution. Its high-intensity sweetening power makes it suitable for products formulated to meet consumer demand for lower-calorie options or those carrying claims such as sugar-free or reduced-calorie. For example, advantame may be found in sugar-free soft drinks, powdered beverage mixes designed for reconstitution with water, and tabletop sweeteners where consumers expect very high sweetness and convenience without the calories associated with sugar. In confectionery and sweets, advantame can contribute to the sweetness profile while minimizing the amount of sugar added, supporting formulations for sugar-free candies, chewing gum, and similar products. Its utility also extends to dairy-based desserts and frozen novelties where sweetness balance is crucial. Beverage categories — including ready-to-drink teas, flavored waters, and sports beverages — often rely on high-intensity sweeteners like advantame to deliver sweetness without added sugars. Through these broad applications, advantame helps manufacturers create products that align with labeling and formulation strategies focused on reducing sugar content. Its use reflects technological and sensory requirements in modern food formulation, enabling development of diverse product lines that appeal to consumers seeking sweetness with minimal caloric impact.
