What is yeast protein?

Yeast protein is a highly nutritious fermented vegan protein source. Derived from the single-celled microorganism commonly known as yeast, it is a complete protein that contains all the essential amino acids needed for optimal human health. Amino acids are the building blocks of proteins. They play a critical role in the growth and repair of your body's muscles, bones, and other tissues. Besides,it is a high-quality source of protein with high bio-availability, the high protein content of yeast protein is derived from the eco-friendly fermentation process, making it an innovative protein source for vegan foods that is free from animal and allergen without unwanted off-notes.

What are the benefits of yeast proteins compared to whey proteins and plant proteins?

Yeast protein contains an exceptional composition of over 80% high-quality protein. Its leucine content and total BCAA conten rivals whey protein. As a slow-digesting protein, yeast protein offers a gradual and consistent supply of amino acids, providing a sustained release. Furthermore, yeast protein is enriched with functional polysaccharides that are beneficial for gut health. As a fermentation product, yeast protein excels over plant proteins in terms of its neutral taste, reliable supply chain, and reduced land requirements for production. These qualities make yeast protein an excellent choice for consumers seeking alternatives to animal protein supplements, while also addressing sustainability concerns.

What are the benefits of fermented yeast protein?

Supports Muscle Growth & Repair: Its BCAA content is crucial for muscle development and post-exercise recovery.

Promotes Satiety: Its slow digestion keeps hunger at bay, aiding weight management.

Improves Gut Health: Studies suggest its prebiotic effects support beneficial gut bacteria, enhancing digestion.

Vegan-Friendly: As a complete protein, it's an excellent alternative for vegans and vegetarians.

Is yeast protein suitable for the vegetarian cuisine?

Yeast protein is a vegan-friendly protein source, as it is derived from microorganisms rather than animal products. This makes it an excellent choice for people who follow a flexitarian or plant-based diet or have dietary restrictions due to ethical, environmental, or health reasons.

Is yeast protein an allergen?

Yeast protein is derived from fermentation of Saccharomyces cerevisiae. Standard baker's yeast, Saccharomyces cerevisiae, is very easily digested by the human body. Furthermore, yeast is not included in the list of products likely to cause allergies or intolerances, subject to mandatory labelling as per European Regulation 1169/2011. With the application of an effective HACCP program, yeast producers can guarantee that yeast is free of allergens. This program notably includes extensive procedures to avoid cross-contamination and ensure traceability and preparation in accordance with Good Manufacturing Practices (GMPs). However, because yeast contains many types of proteins, yeast may be the cause of an allergic reaction in very sensitive individuals, though this is extremely rare.

How much yeast protein is used in our food and drinks?

There are no limitations on the consumption of yeast protein in the European Union, the United States and China.

How is yeast protein labeled in the ingredient list?

Yeast protein is labelled as "yeast protein" in the ingredient list. This name is based on the requirements of the Local Food Law.

What are the international regulations regarding yeast proteins?

The U.S. FDA approved baker's yeast protein for use in food as a protein nutritional supplement in 1977 (reference regulation: 21CFR§172.325). In the European Union, brewer's yeast proteins obtained by conventional physical and enzymatic methods have been approved as a novel food in 1977 (reference regulation: EU Novel Food status Catalogue).

In 2017, Angel yeast company started the declaration of novel food ingredients of yeast protein, and on December 1, 2023, yeast protein was approved as a new food ingredient by National Health Commission. In 2022, Angel took the lead in promoting the development of industry standards for yeast protein, and on December 20, 2023, the industry standard of Yeast Protein was announced, and it will be implemented on July 1, 2024.

What types of food and beverages can yeast protein be used in?

Yeast protein is vegan, allergen-free, and easy to digest. It has a neutral flavor and is perfect as a protein supplement in various food and beverage applications. Examples of applications are protein powder drinks, protein bars, snacks, meat analogues, snacks, non-dairy and dairy products, bakery and pastry, beverages, and more. It is also suitable for vegan and vegetarian diets and people with food allergies or sensitivities.

Overall, Yeast protein offers a sustainable, high-quality protein source that may help meet the nutritional needs of various individuals and support a healthy lifestyle.

What is the difference between yeast protein and yeast extract?

Yeast protein and yeast extract differ in terms of their composition and usage. Yeast protein is primarily the protein component extracted from yeast, boasting high nutritional value and is primarily used for food fortification and protein supplementation. On the other hand, yeast extract is a more comprehensive yeast product that contains not only protein but also various amino acids, nucleotides, B vitamins, and other nutritional and flavor components. It is primarily used to improve the taste and flavor of food products.

Why is Yeast protein Sustainable? What are the environmental benefits?

Yeast protein is made through an eco-friendly fermentation process that minimizes environmental impact, requires limited land use for cultivation and is less affected by harvest and seasonality that plant-based protein production is subjected to. Research shows that the carbon emission generated during the production of yeast protein is 20 times less than that of beef, so it is a sustainable protein in comparison to other more resource-intensive and environmentally impactful options. Yeast protein production significantly reduces water consumption, occupies less arable land and generates fewer carbon footprints. The wastewater generated from yeast protein production is used as organic fertiliser for yeast crops, creating a circular economy.
