Ways of knowing if yeast is killed or still alive

did i kill my yeast

When preparing any meal, you will always need yeast, which helps activate your food. Failure to use the yeast is sure that the food you are preparing will not rise. Therefore, ensure you have yeast to keep you safe in preparing your food for whatever you are preparing. However, in the activation process, you can kill it without your knowledge which is also bad for your food. Below are signs of knowing if the yeast is bad or still alive.

  • Check the expiry date of the yeast

Most people forget to check the expiry date of any product when buying them such that they can use harmful products with their ideas. If you need to know the expiry date of many products, consider checking on the expiry date of the products to know if they are suitable for use or not; therefore, if the expiry date is on the date, the yeast is killed.

  • Check for bubbles

Checking for bubbles is another way of knowing if the yeast is good or bad. What you need to do when using this method is by giving the yeast time to rest for a bit of time and check if the mixture is bubbling, then the yeast is good, but if it is not bubbling, then the yeast is bad.

  • Check if the yeast is rising

The primary function of why people use yeast in making bread, pizza, and other foodstuffs is to make the dough rise. Therefore, when you use yeast, it can make your food rise and when you put it in your dish, it will become fluffy. When you add yeast to the dough several times, and it is not raising it, it can be dead, or that you killed it in processing it.

Leading reasons of yeast going bad

Leading reasons of yeast going bad

Before yeast goes terrible, there must be some reasons that make it wrong in the house. I will discuss the factors below.

1. Temperature

 Not only temperature that makes the yeast go bad but instead it is the high temperature that makes it go wrong. Yeast should be under warm temperatures, which is precisely 185 degrees Fahrenheit. However, when you are using water to activate the yeast, you need specific temperatures to avoid causing issues to the yeast.

It is advisable to use cold water to activate yeast since boiling water can cause the yeast to go wrong since hot water kills some nutrients that make the yeast have the ability to rise. If you dare use the warm water, be sure that your yeast will go wrong.

2. The ratio of yeast to water

When mixing water and sugar, it is good to use a certain level of nutrients since using excess yeast in a small amount of water for activations fails the process and can even kill it. Therefore, ensure you add the right amount of yeast with water. The water to yeast ratio should be of a certain level.

If the ratio is complex for you to recognize, consider asking the professionals who can estimate the proper amount needed. If you are adding any of the materials, ensure you add both of them so that the ratio becomes good. Adding more or less yeast in ratio with the water fails the activation of the yeast.

3. Add salt to the yeast

The only ingredient needed in the yeast during activation is sugar. Therefore, when you add salt in place of sugar, you will have killed the yeast, and the activation process can fail. Remember, salt kills yeast. That is what you should have in mind.

4. Using other ingredients in place of sugar

People assume that using other alternatives in place of sugar is good without knowing that it kills the yeast with some alternatives. Sugar can only work in sugar and milk, and if you use a different thing, you are probably killing your yeast. The only alternative with sugar is honey. Avoid using maple syrup, raisins, or syrup since they kill the yeast.

5. Using a beater

When preparing any dessert, we need to beat it, which people use with yeast activation. When activating yeast consider stirring with a spoon but do not use electric beaters since stirring is good, and with the process of dissolving, the warm water helps in dissolving.

6. Using yeast alternatives

There are many different yeast alternatives that you can use in place of yeast. Some of the alternatives are good in that they can help, while some are bad for your food preparation. Some of the alternatives include baking powder which is among the best alternatives, yogurt, instant dough starter, chili stem, and lemon juice.

What can one do to avoid killing yeast?

  • I am using a thermometer. Consider using a thermometer when checking water temperature for activating yeast to reduce some scenarios.
  • Using a hand whisk.  In the process of mixing sugar, water and yeast, ensure you use a hand whisk without necessarily beating it.

Frequently asked questions:

  • Is it advisable to use dead yeast?

No, it is not good to use the dead yeast since the importance of using yeast is to raise the dough, so when the yeast is wrong, it is not of any function to the food.

  • What is the longest time for yeast that is there to raise dough?

The maximum time for the yeast to rise is thirty minutes, while the minimum time is about 30 minutes. If you are in a hurry, you can check after 10 minutes.

  • What is the smell of lousy yeast?

To identify the smell of yeast by the smell, you first need to know the smell of the good one to differentiate even though the bad one smells terrible.


As a yeast user, you can be asking yourself if the yeast you are using is good or bad or if you killed the yeast you need to use. I have provided you with ways of checking if you have killed your yeast or not. There are tips for preventing killing yeast and what you usually do to kill the yeast.
