If you want your shredded Parmesan cheese to have an extended shelf life once it has been opened, you should either store it in plastic containers that can be resealed again or in containers that are airtight.

You can store the shredded Parmesan cheese in the freezer and use it within the period indicated for refrigeration after the box has been opened.

Because bacteria multiply very quickly at temperatures ranging from 40 to 140 degrees Fahrenheit, shredded Parmesan cheese that has been left out for more than two hours at room temperature should be discarded.

The shredded Parmesan cheese should be frozen after it has been opened so that it may maintain its quality for a longer period of time.

To freeze shredded Parmesan, first, ensure that the original packaging is completely airtight, and then store the cheese in the freezer. If you plan to freeze the cheese for more than two months, you must place the original packing inside of a freezer bag that is made of heavy-duty material.

Shredded Parmesan cheese kept in the freezer in the correct manner will keep its optimum quality for approximately eight months, but it will continue to be safe to eat after that time.

If cheese develops an unpleasant smell, taste, or look, it should be thrown away. If mold grows on the shredded Parmesan cheese, the whole content should be thrown away.

Place the shredded parmesan cheese into the container so that it may be frozen. Take out the amount that you want to preserve in the refrigerator, and then put the remaining amount in an airlock container and store it in the freezer. 

Be sure to date and label it. Shredded Parmesan cheese may be stored in the freezer for up to six months.

First, you should remove all of the extra air from the container, then close it, this will give additional safety. Because the shredded parmesan cheese is likely to go bad in the presence of air. 

It will also hold any cheese that might fall out if the lid is open in the freezer. This will keep you from wasting cheese and creating a mess in the freezer.

If you freeze it, shredded Parmesan cheese will stay good for anywhere between three and six months. You may use frozen shredded parmesan cheese right out of the freezer, just shake it before you use it to break any clumps that may have formed.

Mold is the major indicator that shows that the shredded parmesan cheese has gone bad. If you store the shredded cheese for too long in the fridge or leave it in the kitchen, mold may grow on it. 

If you find mold in shredded parmesan cheese, you should generally just throw out the whole container since it might be difficult to determine precisely where the mold is or where it originated from.

However, if the whole container of shredded parmesan cheese is discolored, then you should discard the whole container. 

Another indication of bad shredded parmesan cheese is its unpleasant smell. The cheese that has gone bad will have a harsh smell and should be discarded. 

You may likely be familiar with the aroma of freshly shredded parmesan cheese, and your senses can detect the odors of ruined or rancid shredded parmesan cheese.
