What is Fresh Yeast?
Fresh yeast, also known as baker’s yeast or compressed yeast, is a type of yeast that is used in baking to make bread rise. It is made from a living organism called Saccharomyces cerevisiae, which is a type of fungus. Fresh yeast is typically sold in small blocks or cubes and has a moist and crumbly texture.
When fresh yeast is mixed with warm water and sugar, it activates and starts to produce carbon dioxide gas. This gas gets trapped in the dough, causing it to rise and create a light and fluffy texture in the finished bread. Fresh yeast is known for its strong fermentation power, which makes it an excellent choice for bread baking.
Unlike active dry yeast or instant yeast, which are dormant and need to be rehydrated before use, fresh yeast is already active and ready to use. It does not require any additional steps like proofing or activating, which makes it a convenient option for home bakers.
Characteristics of Fresh Yeast:
1. Moist and crumbly texture.
2. Requires refrigeration to maintain freshness.
3. Has a shorter shelf life compared to other types of yeast.
Fresh yeast is highly perishable and needs to be stored properly to maintain its freshness. It should be kept in the refrigerator between 0-4°C (32-39°F) and used within 2-3 weeks.
Note: Fresh yeast can also be frozen to extend its shelf life. When frozen, it can last up to 3 months. However, it is important to note that freezing may slightly affect its performance.
In conclusion, fresh yeast is a living organism that plays a crucial role in bread baking. Its ability to ferment and produce carbon dioxide gas helps bread to rise and achieve a light texture. Remember to store it properly in the refrigerator or freezer to maximize its freshness.
How Does Fresh Yeast Work?
Fresh yeast is a type of yeast that is commonly used in baking to help dough rise and give bread its light and fluffy texture. It is made up of living microorganisms, specifically Saccharomyces cerevisiae, which is a species of yeast that ferments sugars in the dough and produces carbon dioxide gas. This gas gets trapped in the dough, causing it to rise and expand during the baking process.
When fresh yeast is added to the dough, it feeds on the sugars present, converting them into carbon dioxide and alcohol through the process of fermentation. The carbon dioxide gas gets trapped in the dough’s gluten network, causing it to expand and rise. The alcohol produced by fermentation evaporates during baking, leaving behind the desired texture and flavor in the finished bread.
Fermentation Process
The fermentation process is essential for yeast to work its magic in bread-making. When the dough is mixed with fresh yeast and warm water, the yeast becomes activated and starts to feed on the sugars in the dough. As the yeast ferments the sugars, it produces carbon dioxide gas, which creates air pockets in the dough. This trapped gas causes the dough to rise and become light and airy.
Gluten Development
In addition to fermentation, fresh yeast also plays a role in developing gluten in the dough. Gluten, which is formed when water mixes with proteins present in flour, gives bread its structure and elasticity. The carbon dioxide gas produced by the yeast during fermentation helps to stretch and strengthen the gluten network, creating a well-risen and airy bread.
It’s important to handle fresh yeast with care to maintain its activity. Store it in the refrigerator or freezer to extend its shelf life and use it according to the recipe instructions. Fresh yeast brings life to bread dough, and with the right conditions and techniques, it can help you achieve delicious homemade bread.
