What are Yeast Extracts?
Yeast is a single cell micro-organism (fungus) that converts sugar and starch into carbon dioxide bubbles and alcohol.
Saccharomyces cerevisiae is commonly known as bakers or brewers yeast. The yeast ferments sugars present in the flour or added to the dough, giving off carbon dioxide (CO2), which inflates the dough during proof and the early stages of baking. Alcohol (ethanol) is also produced but this is burnt off during the baking process.
The bubbles in sparkling wines such as Champagne are trapped CO2, the result of yeast fermenting sugars in the grape juice. One yeast cell can ferment approximately its own weight of glucose per hour, giving rise to large volumes of CO2.
Yeast extracts are obtained by biological methods from the protein-rich cell sap of especially suitable bakers yeasts. This extract is rich in valuable amino acids and vitamin B complex, nucleotides and other useful cell constituents. Yeast extracts are used as natural flavour enhancers in many foods; they offer a very natural way of intensifying and rounding the natural flavour.
Yeast products can be used for a wide range of applications:
Yeast extracts can be used across the entire flavouring area. Products are equally suitable for premixing in the condiment and snack area and for the traditional application areas in soups, sauces and the ready-cooked meals.
Special vitamin yeast powder consists of a pure, inactivated yeast (S.cerevisiae ), the nutritional value of which is increased by a supplement of the vitamins niacin, vitamin B1, vitamin B2 and vitamin B6. The products have a pleasant, yeast-typical taste. Auxoferm special vitamin yeast powder has a good water binding and emulsifying capacity. It is excellently suitable for tabletizing.
Beta-(1,3)/(1,6) Glucan is known as an immunostimulant derived from the cell walls of bakers yeast. It activates white blood cells, such as macrophages, granulocytes and monocytes, responsible for defence against infections, and supports the repair of damaged tissues in the body.
