Abstract:
Brazzein is a small sweet-tasting protein found in the red berries of a West African evergreen shrub, Pentadiplandra brazzeana Baillon. Brazzein is highly soluble and stable over a large pH range and at high temperatures, which are characteristics that suggest its use as a natural sweetener. However, Pentadiplandra brazzeana culture is difficult at a large scale, limiting the natural source of brazzein. Heterologous expression of brazzein has been established in numerous systems, including bacteria, yeast, and transgenic plants. Brazzein requires four disulfide bonds to be active in eliciting

Abstract:
Brazzein, a 6.5-kDa protein consisting of 54 amino acids and four disulfide bonds, is the smallest sweet-tasting protein yet isolated from the wild African plant Pentadiplandra brazzeana. Brazzein has various desirable properties for use as a low-calorie sweetener in the diets of individuals suffering from diabetes, obesity, and metabolic syndrome. For example, brazzein has a high water solubility and a high thermostability. In addition, brazzein is 2000-times sweeter than sucrose on a weight basis. Both the solution and crystal structures of brazzein have been reported. In the crystal structu

Abstract:
In the modern world, due to the overconsumption of sugar-containing products, the problem of obesity is relevant. Among the many sweeteners that minimize sugar intake, a group of sweet-tasting proteins is up-and-coming. Brazzein is the smallest of the sweet proteins (54 aa, 6473 Da), and it is also safe for obese and diabetic people since it does not affect blood sugar and insulin levels. Brazzein has high thermal stability over a wide pH range: from 2 to 8 [1]. To increase the level of sweetness of brazzein, mutant variants of this protein were created through site-directed mutagenesis, the s

Abstract:
Naturally sweet proteins have no glycemic effect and offer a fundamentally new approach to sweetness and health for individuals seeking to reduce their added sugar intake. However, unlike many commercial sweeteners, little research has been performed on the potential safety implications of adding these uniquely sweet proteins to food and beverages. In this study, a naturally sweet protein found in the West African Oubli plant ( Pentadiplandra brazzeana), referred to as Oubli fruit sweet protein or brazzein, was expressed in Komagataella phaffii (formerly Pichia pastoris) and produced via preci

Abstract:
This article presents the results of a comprehensive toxicity assessment of brazzein and monellin, yeast-produced recombinant sweet-tasting proteins. Excessive sugar consumption is one of the leading dietary and nutritional problems in the world, resulting in health complications such as obesity, high blood pressure, and cardiovascular disease. Although artificial small-molecule sweeteners widely replace sugar in food, their safety and long-term health effects remain debatable. Many sweet-tasting proteins, including thaumatin, miraculin, pentadin, curculin, mabinlin, brazzein, and monellin hav

Recently, customers have been keener to buy products manufactured using all-natural ingredients with positive health properties, but without losing flavor. In this regard, the objective of the current study is to review the consumption of brazzein and monellin, their nutritional profiles and health effects, and their potential applications in the food industry. This poses challenges with sustainability and important quality and safety indicators, as well as the chemical processes used to determine them.
