Yeast extract is made from natural bakers’ or brewers’ yeast. Fresh yeast was currently an important part of food culture in earlier advanced civilizations. It was not only used for baking bread but also for making beer as well as wine.
Yeast extract is obtained from fresh yeast in a 5-step procedure. Enzymes break down the proteins existing in the yeast cells into smaller components and dissolve the surrounding cell wall so that the element leaves the cell. The remains of the cell wall are removed by splitting up. Therefore, yeast extract contains proteins, amino acids, carbohydrates, vitamins, and minerals from the yeast cell without the surrounding cell wall.

Composition of yeast extract

Yeast extract has about 50% protein content. Out of this, 20% is glutathione. It is abundant in amino acids, dextrans, vitamin B, biotin, and trehalose. Calcium, phosphorus, and trace element are also present in yeast extract. It is free of cholesterol and fatty acids.

Types of yeast extract

Autolyzed yeast

Autolyzed yeast- the yeast extract is obtained by breakdown of the yeast cell and release of constituents in the mixture by its own enzymatic activities. The soluble components are then separated from insoluble portions of the mix. They are referred to as autolyzed yeast extract.

Hydrolyzed yeast

Hydrolyzed yeast- the yeast extract is made by adding acid or enzyme to the yeast and sugar mixture. This enzyme produces extract by the process of hydrolysis. It is widely used in the cosmetics industry.

Powder
