Storage of cheese


Cheese must be properly stored to ensure their quality. Unopened cheese may be stored in the refrigerator in temperatures between 34 and 38 degrees fehrenheit. Under this condition, they may retain their freshness beyond their date of expiry. However, to ensure this, cheeses must be tightly sealed or wrapped to prevent entry of airborne microbes and natural mold spores.

Fresh cheese kept tightly sealed and cold as they are high in moisture. Being more perishable than firmer cheese, they should be consumed within two weeks. Examples of such cheese includes the cottage, cream and Mascarpone.

Semi-soft, firm and hard cheese in the refrigerator, may remain fresh and be kept for four to eight weeks. However, like fresh cheese, they must be wrapped tightly. Some aged cheese may be retain their quality under proper storage cheese.

Hard cheese should be stored in their grated form and stored in sealed container under the refrigerator temperature for up to two weeks. They be stored under the freezer temperature if longer storage (3months) is desired, but must be used directly if it is removed. Examples of such cheeses include the parmesan and Asiago. Moreover, freezing of cheese is not always applied to all cheeses. For instance, if cheeses like cheddar and gouda are frozen, this will cause a crumbly texture, which degrades their quality.

Cheese should be tightly wrapped in foil or other moisture proof freezer wrapping and frozen quickly under the 0 degrees fehrenheit to prevent evaporation.

Having more surface area exposed to air, shredded cheeses tend to lose moisture and develop mold more easily than solid pieces. Thus, shredded cheese should be wrapped tightly and used within few days.

If mold are developed on the surface, they should be cut off about ½ inch from each affected side. The remains should be consumed within the week.

Aromatic cheeses, i.e blue and limburger, must be wrapped tightly and stored in airtight containers as they may spread their smell and flavor to other cheese and foods.

Natural cheese should be stored in the refrigerator, and best stored in their original packaging. If cheeses are opened, they should be stored wrapped tightly in the cling plastic wrap, separated from air and moisture.

In general, soft unripened cheeses can be kept for 10-30 days, if opened, for 2 weeks. Ricotta can be kept for 5 days.
Ripened or cured cheeses can be kept unopened for 3-6months, if opened 3-4weeks and if sliced 2 weeks. Examples are cheddar, edam, gouda, swiss and brick.

Cheese such as Brick, Edam, Muenster, Port du Salut, Swiss, Provolone, Mozzarella, and Camembert, Small cheeses, such as Camembert, can be frozen in their original packaging in small pieces, and thawed in refrigerator. They should be used immediately after thawing.
