The Oubli plant is native to West Africa and commonly found in African rainforests. Discovered in 1989, this protein has gained attention for its extreme sweetness, which is about 500 to 2,000 times sweeter than sucrose &ndash; the standard measure for sweetness.<\/p>\n\n\n\n<p>The discovery of Brazzein was reported in 1994. It is the smallest sweet-tasting protein, with a molecular weight of 6,473. Brazzein consists of a single chain of 54 amino acid residues. Four disulfide bonds, which can be found in its structure, contribute to the stability of the protein. This structure has been studied extensively, and the first crystal structure of Brazzein was reported at 1.8 &Aring; resolution.<\/p>\n\n\n\n<p>In addition to its high sweetness potency, Brazzein is characterized by its good sensory properties and a long history of human consumption. Furthermore, it has physicochemical properties that make it a highly stable protein, such as its high water solubility and resistance to various pH levels. This stability, combined with its natural origin and extreme sweetness, positions Brazzein as a promising natural sweetener for various applications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Properties and Structure<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Protein Structure<\/h3>\n\n\n\n<p>Brazzein is a sweet-tasting protein derived from the wild African plant Pentadiplandra brazzeana. It is the smallest known sweet protein, consisting of 54 amino acid residues and four evenly spaced disulfide bonds. The presence of these disulfide bonds contributes to the protein&rsquo;s stability and unique structural characteristics.<\/p>\n\n\n\n<p>The crystal structure of brazzein has been determined at a resolution of 1.8 &Aring;, which revealed a compact and well-defined folding pattern. The protein consists of one alpha-helix and three strands of anti-parallel beta-sheet. This structure was also confirmed in solution through proton nuclear magnetic resonance (NMR) studies conducted at a pH of 5.2 and 22 &deg;C.<\/p>\n\n\n\n<p>Some key properties of brazzein include:<\/p>\n\n\n\n<ul>\n<li><strong>Sweetness:<\/strong> Brazzein is known for its intense sweetness, which is about 2000 times that of sugar.<\/li>\n\n\n\n<li><strong>Solubility:<\/strong> The protein is highly water-soluble, with a solubility of at least 5% in water.<\/li>\n\n\n\n<li><strong>Heat stability:<\/strong> Brazzein is considered the most heat stable among sweet proteins, which makes it an attractive target for research on sweet protein structure and function.<\/li>\n\n\n\n<li><strong>pH sensitivity:<\/strong> The sweet taste of brazzein can be affected by changes in pH, but it generally remains stable in a wide range of pH levels, typically from about 3 to 10.<\/li>\n<\/ul>\n\n\n\n<p>As a small yet highly stable and sweet protein, brazzein offers potential applications in the development of alternative sweeteners and nutritional products. Further research on its structure, biochemistry, and potential uses may expand our understanding of this unique protein and its potential role in food science.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Natural Sources and Production<\/h2>\n\n\n\n<p>Brazzein is a naturally occurring protein that can be found in the fruit of the West African climbing plant, Oubli (Pentadiplandra brazzeana Baillon). This plant is a primary source of this soluble protein, which possesses a high sweetness level, estimated to be approximately 1500 times sweeter than sucrose. Containing only 54 amino acids, brazzein is a small-sized protein present in the extracellular region, specifically in the pulp tissue surrounding the seeds.<\/p>\n\n\n\n<p>The Oubli plant, native to West Africa, is a climbing plant that produces small amounts of brazzein in its fruits. Consequently, researchers have devised methods to mass-produce the protein by synthesizing it with bacteria, such as Escherichia coli. The resulting product retains the properties of brazzein: a heat-stable, zero-calorie sweetener with little or no bitter aftertaste.<\/p>\n\n\n\n<p>Commercial production of brazzein has been successfully achieved through collaborations between industry partners like Sweegen and Conagen. These companies have utilized precision fermentation techniques to scale its production, addressing taste challenges typically associated with natural sweeteners. However, substituting sugar with a high intensity sweetener like brazzein in a one-to-one ratio may not yield the desired product attributes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Comparison to Other Sweeteners<\/h2>\n\n\n\n<p>In this section, we will compare brazzein to other types of sweeteners, both artificial and natural.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Artificial Sweeteners<\/h3>\n\n\n\n<p>Aspartame is a widely used artificial sweetener that has a sweet perception with a slight delay, longer than brazzein&rsquo;s sweet taste. On a weight basis, brazzein is much sweeter than aspartame, being <strong>500 to 2000 times sweeter than sucrose<\/strong> compared to aspartame which is approximately 200 times sweeter than sucrose.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Natural Sweeteners<\/h3>\n\n\n\n<p>Several natural sweeteners exist, such as stevia, monk fruit, and other sweet proteins like thaumatin, monellin, curculin, miraculin, pentadin, and mabinlin. Some characteristics of these sweeteners in comparison to brazzein are:<\/p>\n\n\n\n<ul>\n<li> <strong style=\"font-size: revert; color: initial;\">Thaumatin<\/strong><span style=\"font-size: revert; color: initial;\">: Although thaumatin is also a sweet protein, brazzein&rsquo;s sweet perception is more similar to sucrose. Thaumatin lacks the clean sweet taste and lingering aftertaste of brazzein.<\/span><\/li>\n<\/ul>\n\n\n\n<ul>\n<li> <strong style=\"font-size: revert; color: initial;\">Stevia<\/strong><span style=\"font-size: revert; color: initial;\">: Steviol glycosides, including Reb M, are the sweet compounds found in stevia. Stevia is derived from the Stevia rebaudiana plant and is about 200 to 300 times sweeter than sugar. However, it has a slightly bitter aftertaste, which is not present in brazzein.<\/span><\/li>\n<\/ul>\n\n\n\n<ul>\n<li> <strong style=\"font-size: revert; color: initial;\">Monk fruit<\/strong><span style=\"font-size: revert; color: initial;\">: Also known as <\/span><em style=\"font-size: revert; color: initial;\">Siraitia grosvenorii<\/em><span style=\"font-size: revert; color: initial;\">, monk fruit contains mogrosides that are responsible for its sweetness. Monk fruit extract is about 150 to 250 times sweeter than sugar. It&rsquo;s important to note that brazzein is still significantly sweeter than monk fruit extract.<\/span><\/li>\n<\/ul>\n\n\n\n<ul>\n<li> <strong style=\"font-size: revert; color: initial;\">Other sweet proteins<\/strong><span style=\"font-size: revert; color: initial;\">: Monellin, curculin, miraculin, pentadin, and mabinlin are also natural sweet protein compounds found in various plants such as <\/span><em style=\"font-size: revert; color: initial;\">Curculigo latifolia<\/em><span style=\"font-size: revert; color: initial;\"> and <\/span><em style=\"font-size: revert; color: initial;\">Synsepalum dulcificum<\/em><span style=\"font-size: revert; color: initial;\">. Brazzein, with its small molecular weight of 6473 and 54 amino acid chain, is the smallest among these sweet proteins.<\/span> <\/li>\n<\/ul>\n\n\n\n<p>In conclusion, brazzein has a sweet profile closer to sucrose and is more potent as a sweetener compared to other natural and artificial sweeteners. Its clean taste, lack of bitterness, and stability in a wide range of pH make it an attractive choice for various food and beverage applications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sweet Taste Receptor Interaction<\/h2>\n\n\n\n<p>Brazzein is a sweet-tasting protein extracted from the West African fruit of the climbing plant Oubli (Pentadiplandra brazzeana Baillon). It is known for its potent sweetness, which is stronger than sugar, making it an interesting subject for understanding the sweet taste receptor interaction.<\/p>\n\n\n\n<p>The sweet taste receptor is a heterocomplex comprised of two subunits, T1R2 and T1R3. These GPCR family membrane proteins are responsible for the sensation of sweetness. Homology modeling and low-resolution docking have been employed to examine the potential interaction between brazzein and the sweet taste receptor.<\/p>\n\n\n\n<p>Brazzein is recognized to bind to the taste receptor T1R3. Though it is not yet known if brazzein binds to the receptor T1R2, it is assumed that brazzein interacts with the heterocomplex formed by T1R2 and T1R3 for sweet signaling. This interaction is crucial for evoking the sweet taste sensation.<\/p>\n\n\n\n<p>Mutations in the brazzein protein can have a significant impact on its sweetness profile. For example, the D29K mutation results in a stronger sweetness, while the R43A mutation leads to a reduction in the protein&rsquo;s sweetness. This indicates that specific amino acid positions in the protein play a crucial role in modulating the perception of sweetness.<\/p>\n\n\n\n<p>Charge also plays a role in brazzein&rsquo;s interaction with the sweet taste receptor. The mutations mentioned above involve changes in the charge of the amino acids at the respective positions, which can affect the way brazzein binds to the receptor and subsequently how it tastes.<\/p>\n\n\n\n<p>An intriguing characteristic of brazzein&rsquo;s sweetness profile is the ability to produce a lingering sweet taste. This is possibly related to the interaction between brazzein and the sweet taste receptor, as the protein-receptor interaction could be more stable due to factors such as charge and amino acid positioning.<\/p>\n\n\n\n<p>In summary, the interaction between brazzein and the sweet taste receptor is a complex process influenced by factors like mutations, charge, and structural characteristics of the protein itself. Understanding these interactions is essential for the development of alternative sweeteners and advancing the field of taste research.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Applications and Market Potential<\/h2>\n\n\n\n<p>Brazzein is a small heat- and pH-stable sweet-tasting protein isolated from the West African plant, Pentadiplandra brazzeana.

This makes it an ideal choice for low-calorie and sugar-free products in the market while maintaining the desired texture and flavor.<\/p>\n\n\n\n<p>As a protein sweetener, Brazzein can be used in <strong>fermentation processes<\/strong> to enhance the taste of fermented products, such as dairy alternatives and probiotic foods. Its stable nature in a wide range of pH levels ensures consistent sweetness throughout the fermentation process.<\/p>\n\n\n\n<p>Regarding <strong>regulatory approval<\/strong>, it&rsquo;s important to note that Brazzein is yet to receive Generally Recognized As Safe (GRAS) status. However, other natural protein sweeteners like thaumatin have been granted GRAS status based on their safe use in Africa, which could pave the way for Brazzein&rsquo;s approval.<\/p>\n\n\n\n<p>In summary, Brazzein offers a promising alternative for sugar reduction in various industries, including beverages, baking, and fermentation. Its high-intensity sweetness, heat stability, and pH compatibility make it an attractive option for product developers in the zero-calorie and sugar-free market segments.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Research and Development<\/h2>\n\n\n\n<p>Brazzein is a sweet-tasting protein isolated from the West African Oubli plant (Pentadiplandra brazzeana) and has garnered interest due to its remarkable sweetness, which is approximately 1500 times greater than sucrose. This small protein contains 54 amino acids and has a low molecular mass of 6,473 Da, making it more stable under various conditions such as heat and pH changes.<\/p>\n\n\n\n<p>Researchers at the University of Wisconsin have conducted studies on Brazzein using chemical synthesis, X-ray analysis, and NMR studies to determine its structure. These methods provided valuable insights into the arrangement of amino acids and the disulfide bonds, contributing to the protein&rsquo;s stability and sweet taste profile.<\/p>\n\n\n\n<p>Advancements in biotechnology have enabled the production of Brazzein through fermentation technology, which involves the use of genetically modified organisms like Escherichia coli (E. coli) to produce the protein. Companies such as SweeGen and Conagen have developed efficient fermentation processes, creating a sustainable and cost-effective approach to obtain Brazzein.<\/p>\n\n\n\n<p>One potential application of Brazzein is its use in the food industry as a natural, high-intensity sweetener. Given its attractive properties, it can be incorporated into food products tailored for diabetics as it does not impact insulin levels. Additionally, its stability under pasteurization and high temperatures makes it suitable for various food processing methods.<\/p>\n\n\n\n<p>Brazzein has been found to have potential as a taste-modifying agent beyond sweetness, with its ability to elicit an umami flavor. This characteristic adds another dimension to the possibilities of using Brazzein in the development of novel foods with unique flavor profiles.<\/p>\n\n\n\n<p>In conclusion, research and development efforts have been instrumental in uncovering the potential of Brazzein as an alternative sweetener and taste modifier. Companies like SweeGen and Conagen have utilized modern fermentation technology to produce the protein on a commercial scale, exploring its use in various food products and formulations.

It possesses high potency, being 500 to 2,000 times sweeter than regular sugar, and a clean sweet taste with little to no lingering or bitter aftertaste. However, there are some challenges and limitations associated with its use.<\/p>\n\n\n\n<p>One of the challenges in utilizing brazzein as a sweetener is its potency. Although it is a highly potent sweetener, high concentrations can result in an undesired intensity of sweetness and possibly some sourness. The desired sweetness level may require the use of very small amounts of brazzein, which can complicate formulation processes and increase costs.<\/p>\n\n\n\n<p>Another challenge is related to the natural sourcing and production of the protein. While brazzein is found in nature, it is not readily available in large quantities, and its extraction from the plant is labor-intensive. This has led to the development of recombinant proteins &ndash; bioengineered versions of the protein &ndash; that can be produced in larger volumes. However, producing recombinant brazzein involves a complex process that requires optimization for commercial-scale production.<\/p>\n\n\n\n<p>Despite its clean sweet taste, brazzein might still interact with sweet receptors in a way that can cause a lingering aftertaste or sourness in certain formulations. Understanding the chemical ecology and the molecular interactions of brazzein with the sweet receptor can help overcome these challenges. Scientists like Kunisuke Izawa and Motonaka Kuroda have been studying the properties of brazzein to better understand its interaction with the human palate.<\/p>\n\n\n\n<p>In addition, brazzein&rsquo;s safety profile needs to be studied thoroughly. While it is known that Brazzein has been consumed by the people of Gabon for a long time, it is essential to investigate its potential impact on liver function and other physiological processes.<\/p>\n\n\n\n<p>In conclusion, while brazzein shows promise as a natural, high-potency sweetener with a clean taste and minimal aftertaste, several challenges and limitations need to be addressed. Research in areas such as molecular interactions, safety, and large-scale production can help overcome these obstacles and pave the way for brazzein&rsquo;s successful commercialization.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">How is Brazzein produced?<\/h3>\n\n\n\n<p>Brazzein is a sweet-tasting protein extracted from the fruit of the West African climbing plant Oubli (Pentadiplandra brazzeana Baillon).
