There are a few different ways that you can sterilize vacuum sealed food. You can either use boiling water, a pressure cooker, or an autoclave.
If you choose to use boiling water, you will need to place the vacuum sealed bags into a pot of boiling water for at least 10 minutes. This will kill any bacteria or other contaminants that may be present in the food.
A pressure cooker can also be used to sterilize vacuum sealed food. Simply place the sealed bags into the pressure cooker and cook for the recommended time based on the size and type of food. This method is very effective at killing bacteria and other contaminants.
An autoclave is another option for sterilizing vacuum sealed food. This is a more expensive option, but it is very effective at killing bacteria and other contaminants. Simply place the sealed bags into the autoclave and run it according to the manufacturer's instructions.
