This procedure is like a piece of cake if you follow it in the right way. The pressure cooker for mushrooms works like a savior in this regard, but you can manage to do it using other methods.

We have shared both the ways briefly in this guide. So, let’s move forward with the details!

Steps to Follow for Sterilizing Mushroom Substrate With a Pressure Cooker

We have managed to make the whole sterilization procedure into a step-by-step process for you. Let’s get into the steps to start working!

  • Step-1

For the first step, you have to work with sustained pressure because, under sustained pressure, the water and temperature will be just perfect for making the mushroom grow.

Then you have to check the seal of the cooker properly if there is any chance of wear or not.

If it doesn’t feature a rubber seal, then you can skip this step. Make sure that you are using a stove that is capable of bearing the weight of your cooker.

Here’s a Pro Tip: The procedure needs to start with setting up the optimum temperature. We all know that in atmospheric pressure, water can only get hot before turning into steam.

If you are trying to sterilize with a pot filled with boiling water, then you won’t be successful for sure!

In that case, your substrates won’t get warmer than 100° C ever. So do not attempt to do this in boiling water.

  • Step-2

Now, fill your cooker with 1 inch or 2.5 cm of cold water and your mushroom substrates. It’s better to be in plastic bags. You will need enough water to cover the whole sterilization process.

Close the lid and set the temperature up to maximum, and let the cooker pressure itself up. This step can take a longer period than other ones. The duration depends on the size of your cooker.

  • Step-3

When the pressure will go on 15 psi, let it remain in that phase for 45 minutes.

  • Step-4

Once the cooker becomes capable of overcoming the force of weight, the steam will be released. Leave it at the max temperature for another minute.

After one minute, change the temperature to medium or low. You need to create enough heat so that the steam can hardly move the weight.

  • Step-5

After a few whiles when the time is up, you can shut the stove off and walk away. It will be hard to deal with the substrate for a moment because it will be way too hot.

There is no need to rush into things and pull the bags out. You have to wait for at least one hour anyway.

  • Step-6

Once you find your cooker cool enough, you can pull the bags out, and the next thing you will find the job is done.

These few steps will make your sterilization process done in the safest way.

How Long does it Take to Sterilize Mushrooms in a Pressure Cooker?
