What is Brazzein?

Brazzein is a natural sweet protein isolated from the red berries of the West African tropical plant Pentadiplandra brazzeana Baillon. It is approximately 2,000 times sweeter than sucrose and has a taste very similar to sugar.

Key Advantages of Brazzein:

  • High Heat Stability: Brazzein retains its sweetness even at high temperatures, making it suitable for baking and cooking.
  • Broad pH Stability: Brazzein maintains its sweetness in both acidic and alkaline conditions, allowing for use in acidic beverages and alkaline foods.
  • Excellent Water Solubility: Brazzein dissolves easily in water, making it ideal for use in liquid foods and beverages.
  • High Safety: Brazzein is recognized as a safe food additive by the U.S. Food and Drug Administration (FDA).

Applications of Brazzein:

  • Food and Beverage: Brazzein can be used to sweeten various foods and beverages, such as candy, cookies, beverages, and ice cream.
  • Pharmaceuticals: Brazzein can be used to mask the bitter taste of medications, improving their palatability.
  • Personal Care: Brazzein can be used to sweeten oral care products, skincare products, and more.

Brazzein Production:

  • Natural Extraction: Initially extracted from the natural plant, this method is expensive and has low yields.
  • Genetically Engineered Production: Currently, Brazzein is primarily produced in yeast or E. coli using genetic engineering techniques.

Market Potential of Brazzein:

Brazzein is a natural sweet protein with a wide range of potential applications. It is expected to see widespread use in the coming years.

Additional Capabilities of CopX:

CopX can also develop other types of sweet proteins, expanding the options available for various applications. We are planning to create multiple flavor proteins in the near future for drinks and fermentation meat.


Brazzein offers a compelling value proposition as a natural, safe, and versatile sweetening agent. Its potential across food, beverage, pharmaceutical, and personal care industries is significant. With its strong research and development capabilities, CopX is well-positioned to capitalize on the growing market for Brazzein and other sweet proteins.
