What is Yeast?

What is Yeast?
Yeast is one of nature’s oldest and most fascinating living organisms — a microscopic fungus that has supported human life for over 6,000 years. It’s the driving force behind bread, beer, and wine, turning natural sugars into energy through a process known as fermentation.
At MH Bioreal Organics, we continue this ancient tradition using yeast as the foundation for our purely organic, plant-based nutrition products.
In collaboration with Agrano AG (Germany), part of the Martin Braun Group, we bring to Australia the world’s first 100 % organic Vitamin B12 yeast flakes — naturally rich in protein, fibre, and essential B-vitamins.
- Living organism — nature’s oldest fermentation partner in food and drink.
- Purely organic — cultivated on certified, chemical-free ingredients.
- Nutrient-dense — naturally rich in protein, fibre & B-vitamins.
- Vegan-friendly — suitable for sustainable, plant-based diets.
- Innovative — world’s first certified organic Vitamin B12 yeast flakes.
How Fermentation Works
In baking and food preparation, yeast consumes sugars (like glucose or maltose) and releases CO₂. This natural gas expansion gives bread its structure, while flavour molecules enrich taste. Yeast is also used in controlled environments to produce inactive or extracted forms for nutritional and savoury applications. According to Agrano’s organic production guide, Bioreal yeast is grown exclusively on organically certified substrates, with no synthetic growth promoters.
- Converts sugars — creates CO₂, alcohol & rich flavour.
- Builds texture — gives bread its rise & rich aroma.
- Certified organic — grown on clean, traceable substrates.
- Nutrient-preserving — retains proteins, fibre & B-vitamins.
- Pure production — no synthetics or chemical growth aids.
Nature’s Fermentation Catalyst
Yeast are single-celled microorganisms that convert natural sugars into carbon dioxide, alcohol, and flavour compounds through fermentation. This biological process has been used in food for thousands of years — from bread and beer to nutritional yeast and yeast extracts. MH Bioreal’s partnership with Agrano ensures that all fermentation follows certified organic standards, maintaining purity and performance without chemical intervention.
- Converts sugars — forms CO₂, alcohol & natural flavour compounds.
- Builds structure — gives bread its rise and balanced aroma.
- Organically produced — grown on clean, traceable substrates.
- Low-impact method — clean, sustainable fermentation.
- Balanced taste — smooth umami & lasting aroma.
Origins
The Evolution of Yeast — Nature to Nutrition
Discover how one of the smallest living organisms on Earth became one of humanity’s most powerful natural allies — transforming from an ancient fermenting fungus into a cornerstone of modern nutrition, flavour, and sustainability.
The first brewers and bakers in Mesopotamia and Egypt unknowingly harnessed yeast while crafting bread and beer. This tiny organism — a single-celled fungus — began humanity’s partnership with fermentation, bringing rise, flavour, and preservation long before science understood why.

With the invention of the microscope, yeast was revealed as a living cell. In 1857, Louis Pasteur proved that yeast causes fermentation — transforming sugar into alcohol and carbon dioxide. This breakthrough marked yeast as one of nature’s earliest known microorganisms and laid the foundation for modern food science.
Building on centuries of discovery, MH Bioreal Organics — in collaboration with Agrano AG (Germany) — continues yeast’s evolution with the world’s first 100 % organic Vitamin B12 yeast flakes.
Our organic yeast products combine ancient fermentation wisdom with today’s sustainable biotechnology — providing clean, plant-based nutrition that’s rich in protein, fibre, and natural B-vitamins.
How Fermentation Works → What Makes Ours Different
Organic vs Conventional Yeast Production
Bioreal organic yeast differs fundamentally from conventional yeasts. Unlike standard molasses-based fermentation, Bioreal uses only certified organic grain media, ensuring full traceability and sustainability. The process eliminates synthetic vitamins, anti-foam agents, and chemical acids traditionally used to speed up autolysis.

Why Organic Certification Matters
Under EU and Australian standards, organic certification ensures all inputs — from substrate to packaging — are free from synthetic chemicals. MH Bioreal’s yeast products comply with the IFOAM and Australian Certified Organic frameworks. This means clean flavour, traceable ingredients, and full vegan compatibility.
