YEAST – THE WONDER FUNGUS
For most of us, the word Yeast brings to mind warm loaves of bread, frothing glass of beer or chilled wine. As a leavening agent, and as an aid to fermentation, this microscopic fungus is a living organism that induces change when added as a catalyst to various products and processes.
The yeast cell is egg-shaped and is not visible to the naked eye. The size of a single cell is around 6 to 8 thousandths of a millimetre, which is as small as a pinhead. A 1 cm cube of yeast weighs around 1g and it can contain more than 10 billion living yeast cells!
It is believed that yeast was discovered 5000 years ago by the Egyptians, who used it as a “miracle” ingredient to make bread. Centuries later, in 1857, the French scientist Louis Pasteur’s pioneering research established the key role of yeast as the micro-organism responsible for alcoholic fermentation. Pasteur proved that the yeast cell can live with or without oxygen.
In the process of bread baking, yeast does not find any oxygen. Production of carbon dioxide causes the dough to rise. In a brewery, yeast is added to malted grains and allowed to ferment. Wine is produced by the fermentation of fruit. Different strains of yeast are used in the process, to give the end product distinct flavors.
Yeast is said to contain nutritive substances and proteins. Dried yeast cells contain 40%-50% of protein, while some strains may contain fat. Yeast finds application in varied activities, such as food processing, flavouring and pharmaceuticals.
Yeast Powder Manufacturers also market Brewer’s yeast as a nutritional supplement. It’s a rich source of chromium, which can help the body maintain normal blood sugar levels, and is also a source of B vitamins.
Certain strains of Yeast are now used to make biofuels from renewable agricultural products - beet, sugar cane, molasses and other products. Research is currently focusing on the transformation of new raw materials into biofuels. Research is in progress to produce second-generation biofuels from more diversified resources, taking cellulose from plant fibres not grown for human food consumption, e.g. wood, the non-food parts of plants (stems, leaves, etc.) or plant waste.
Yeast has uses in improving animal health too. Dry Yeast Powder contains essential minerals, amino acids and multiple vitamins that provide complete nutrition during the growth of animals. This powder is fed to chicken and cattle to increases muscle and tissue growth, and improve immunity.
