When converting fresh yeast to dry yeast, more specific steps and controlled conditions need to be taken. Here is a more detailed description:

1. 1. Choose the right fresh yeast

When choosing fresh yeast, make sure it is active and healthy. It’s best to choose fresh yeast from a reliable supplier to ensure consistent quality and results. Fresh yeast should be moist, uniform and odor-free.

1. 2. Cultivate fresh yeast

In order to increase the quantity and activity of fresh yeast, you can culture it through the following steps:

- Prepare a clean container, preferably glass. Wash the container with hot water and soap and rinse thoroughly to ensure a sterile environment.

- Add a certain amount of warm water (temperature approximately 37°C to 40°C) to the container. Warm water helps activate the yeast.

- Add appropriate amount of sugar (such as glucose or caster sugar) and flour and mix well to form a thick paste. Sugar provides nutrients and promotes yeast growth.

- Add fresh yeast to the container and stir gently to ensure even distribution.

- Cover the container and place it in a warm, dry place to allow the yeast to ferment. This process usually takes several hours until the yeast is actively fermenting and producing bubbles.

1. 3. Dry fresh yeast

Once the fresh yeast is actively fermenting, you can begin converting it into dry yeast. Here are the steps for drying fresh yeast:

- Prepare a tool for drying the yeast, such as an air dryer or oven. Make sure tools are clean and sanitized.

- Pour actively fermenting fresh yeast into a shallow dish or parchment paper and spread it evenly in a thin layer. Make sure the yeast is thin and even, this helps with the drying effect.

- Place a shallow plate or baking paper inside the drying yeast, making sure there is good ventilation. Aeration helps the yeast drying process.

- Fresh yeast is dried at low temperature, usually at a temperature of 30°C to 40°C. Excessively high temperatures may destroy yeast activity.

- During the drying process, regularly check the status of the yeast. Once the yeast is completely dry, it will become brittle and hard.

-Place dry yeast in an airtight container to keep it dry and fresh.

1. 4. Storing and using dry yeast

The following matters need to be noted when storing and using dry yeast:

- Store dry yeast in a dry, cool place away from sunlight and moisture. Sealing containers prevents moisture from entering.

- Check the shelf life of dry yeast and make sure it is still fresh and effective before using. Expired dry yeast may lose activity.

- When using dry yeast, it usually needs to be reactivated. Dry yeast can be activated by adding it to warm water and adding a small amount of sugar or flour.

- Follow specific recipes and instructions for using the right amount of dry yeast for baking and fermentation.

1. Fresh yeast can be successfully converted into dry yeast by carefully controlling the conditions of cultivation, drying, and storage. Doing so extends the shelf life of the yeast and makes it more convenient to use, bringing convenience and consistent results to baking and fermentation processes.
