Processed cheese is preferred by those people who do not like hard cheeses or want to diversify their diet. This product occupies a fairly important place in human nutrition. Processed cheese appeared in Switzerland even before the First World War began. A large quantity of this product was produced in a place called Thun. And so that the cheese would not disappear, they decided to melt it. As time passed, the production process for this product changed.
Processed cheese contains balanced essential amino acids, phosphorus, calcium salts, as well as a high concentration of fat and protein. The production of processed cheese is based on different types of hard cheeses. The product also includes butter, cream and milk powder. Melting salts are added to prevent the milk protein from curdling. Processed cheese is divided into different types. There are the following: sausage cheeses, slice cheeses, spreadable cheeses and sweet cheeses. The type of product depends on the technology by which it was made, as well as depending on the chemical composition. Unlike hard cheese, the processed product contains less cholesterol and is 100 percent absorbed by the body. This product can be considered complete, so it is important to know the shelf life of processed cheese. It contains calcium and phosphorus, which have a beneficial effect on bones, nails and hair. Since processed cheese contains fats, which are considered high-calorie carriers of fat-soluble vitamins, the human body is enriched with useful substances. Among them are polyunsaturated fatty acids and vitamins A, D and E.
This product also contains large quantities of casein. This is a high-quality protein that contains essential amino acids for the human body. So many people will benefit from this product and they should find out the shelf life of processed cheese. Since this product is high in calories, it should not be consumed in large quantities. People who suffer from cardiovascular diseases and hypertension should avoid eating processed cheese. This is due to the fact that the product contains sodium in greater quantities than the solid forms. Allergies are possible when eating processed cheese due to the fact that some types contain phosphate food additives. Also, people who have kidney problems may suffer from this, so it is worth looking at the composition and shelf life of the cheese. Due to the addition of citric acid to some types of processed cheeses to accelerate ripening, people with high acidity of gastric juice may experience discomfort. Some manufacturers take advantage of the popularity of this product and often offer surrogate analogues rather than the natural product. That is why you should be especially careful when choosing processed cheese. This product is often used in cooking for preparing various dishes, and not just consumed as a separate food. The shelf life of processed cheese is 6 to 7 months. The opened product should be wrapped well, otherwise it will dry out quickly.
In production
The product can be stored in cellars, pipe- or air-cooled chambers, taking into account the required environment, packaging, and packaging. Varieties with insufficient or weak crust are peeled, washed, dried and coated with paraffin. Climatic parameters in production determine the required shelf life of cheese and its maturity. In case of insufficient ripening, the temperature range should be +4...+8 0 C with a humidity of 75-90%.
Only ripe product is suitable for stockpiling. The permissible temperature is -4 0 C, at which microbiological processes on the crust slow down, drying is reduced, and over-ripening is delayed.
The process of long-term savings requires systematic monitoring of product quality. At positive temperatures, inspection is carried out every 7-10 days.
Fridge
Storing cheese in the refrigerator allows you to maximize its freshness, since large temperature changes are harmful to the product, the recommended range is +6...+8 0 C, humidity 85-90%. The ideal place is the lower part near the vegetable chambers. Wrap the product in wax paper, this will prevent the aroma from escaping, but at the same time provide air access.
At room temperature
These conditions provide for a minimum storage period. To extend it, you need to know the following:
- The storage place should be dry and dark;
- The product must be wrapped in a napkin moistened with a salty solution. This will prevent it from becoming airy and dry;
- At room temperature it can be used no later than 7 days;
- If possible, prepare a dry, ventilated place with a wooden surface;
- Home conditions also include storage in a cellar (if there is one).
At home
Storing cheese at home does not allow you to maximize its freshness without special equipment or premises. Therefore, the volume of the delicacy must be calculated so that it is consumed within 1-2 weeks. In a private house, you can place the product in a pantry or cellar, but room temperature is not suitable, the permissible range is 0 ... + 10 0 C with a humidity of 85-90%, taking into account the variety. To prevent drying out, you need a special container for storing cheese, which can replace cheese bags or a budget option - a pan with a cotton rag that absorbs excess moisture.
A warm environment is critical for fermented milk products; it promotes the rapid development of mold and microorganisms. The best way to preserve fresh delicacy is in the refrigerator.
How long can you store without refrigeration?
Cheeses are kept in cool conditions. But there are ways to help preserve the beneficial qualities of the product for 7 days in the open air without refrigeration equipment:
- Soak a cotton towel in the brine and wrap the piece. Place in a dark place. Every day, additionally moisten the fabric with brine. Salt will prevent the proliferation of harmful microorganisms, moisture will protect against drying out.
- Wrap the piece in parchment paper and place in an airtight container. Place in a bucket of ice water and press down with a weight.
Important! These methods are only suitable for durum varieties.
In the store and in the warehouse
In the store, cheese is placed in isolation from other products that emit specific odors. For storage, you need to use a refrigerator or cabinet that provides a temperature of +2...+10 0 C. The duration of storage depends on the type:
- rennet, hard, brine – 15 days;
- fused – 10 days;
- soft – up to 5 days.
The shelf life of cheese after opening the package is less than 5 days, regardless of what kind of packaging it is - cut or grated, sealed in polymer film, vacuum packaging.
In a warehouse, the product is usually stored for a period of no more than 1-2 months under conditions as close as possible to production conditions. Air temperature +2…+8 0 C, humidity 80-87%.
A warm environment is critical for fermented milk products; it promotes the rapid development of mold and microorganisms. The best way to preserve fresh delicacy is in the refrigerator.
In the freezer
Sometimes there is a need to extend the shelf life because immediate use is not planned. Then you can resort to freezing.
- You should know that when frozen, some properties are lost. Possible crumbling. The original aroma is missing;
- It is not recommended to serve a product that has been frozen. Best used in cooking;
- You can grate it before placing it in the freezer. This will make it easier to use after defrosting;
- Soft varieties become watery;
- The product can be stored frozen for 2-3 months.
Depending on the density and preparation technology, different types of cheeses are classified. The difference lies in the taste and conditions required for each variety.
What determines the shelf life of cheese?
This dairy product has special storage conditions. They largely depend on the type of cheese. But there are other factors that allow you to keep it fresh and not eat moldy or spoiled product. Before buying it in a store, you need to know the characteristics of this type of cheese. It is undesirable to eat a product whose shelf life is coming to an end. To preserve cheese at home, it is very important to observe certain conditions of temperature, humidity and other parameters.
Low temperatures are detrimental to this product. After all, cheese is “living”. And at high temperatures it can deteriorate. High humidity leads to mold, and low humidity causes it to dry out. The shelf life of packaged cheese is especially short: if it is cut into pieces, it is edible for no more than 3 days.
Which varieties should not be stored together?
It is forbidden to keep different species together, because each has a unique smell and taste, and is also easily saturated with foreign odors.
Be sure to read:
How to store fresh and dry yeast, can it be frozen?
Each type must be stored in individual packaging. This will prevent the absorption of odors from neighboring dishes and will not allow other products to be saturated with their smell.
Signs of cheese spoilage
This product is obtained as a result of the vital activity of microorganisms, so they say that it ripens. Usually, stores sell already ripened cheese, but microorganisms can develop in it during storage. As a result of the accumulation of protein breakdown products, a rancid taste or excessive pungency may appear. In some varieties, milkstone forms in the form of white dots during storage. This precipitates calcium salts. In addition, pink spots may form on the surface of the cheese - this is a sign of the development of yeast microflora. Dark spots often form, indicating mold growth. White spots and a putrid odor are a sign of the development of putrefactive microflora. If the packaging is damaged, the cheese begins to dry out and lose weight. After freezing, most types of cheese crumble and their taste deteriorates.
Types of cheeses
This product is made from milk. Moreover, cow’s milk, as well as sheep’s or goat’s milk, can be used for this. In accordance with this, as well as with the manufacturing method and the presence of other components, all cheeses can be divided into several types:
- Hard cheeses have a very dense structure. There are no large holes in them; usually they are almost invisible. This is explained by the fact that hard cheeses are under pressure for about 6 months during production. These are varieties such as Parmesan, Gouda, Vityaz, Dutch and others.
- Semi-hard cheeses have a soft consistency, but they are still quite dense. Their holes can be small, medium and even very large, as, for example, in Maasdam cheese.
- Soft cheese has a short ripening period. Often these varieties have a consistency reminiscent of cottage cheese or soft cream. They usually have no crust and are ready to eat right away. These are cheeses such as Adyghe, mascarpone, ricotta, mozzarella and others.
- Brine varieties are ripened and stored in brine. They can have different densities, but are usually very salty. The most famous pickled cheeses are feta cheese, suluguni, and chechil.
- Processed ones contain, in addition to cottage cheese and butter, various other components. This can be cream, vegetable fats, flavorings. To give this cheese a soft consistency, special melting salts are used. There are a lot of processed cheeses, for example: “Druzhba”, “Yantar”, “Viola”, “Hochland” and others.
Storing soft cheeses
This product is best preserved in its original packaging. You can also place it in a sealable container, such as an enamel pan. This storage will protect the soft cheese from chapping. These varieties can be placed in the freezer, they will not lose their taste. But you can store them like this for no more than 3 days. Cheese can also be stored in open packaging for only a few days. It begins to dry out quickly, and in a tightly closed package it can become moldy.
The shelf life of Adyghe cheese is also short, although, unlike other soft varieties, it undergoes pasteurization at high temperatures. But even in the original packaging it is stored for no more than a month, and at home after opening - only a week. It is better to put Adyghe cheese in the refrigerator in a glass container, tightly close the lid and place it separately from other products.
Low temperatures are detrimental to this product. After all, cheese is “living”. And at high temperatures it can deteriorate. High humidity leads to mold, and low humidity causes it to dry out. The shelf life of packaged cheese is especially short: if it is cut into pieces, it is edible for no more than 3 days.
Recommendations
Some tips will help you preserve cheese longer without losing its properties or deteriorating its taste:
- It is recommended to avoid sudden changes in temperature;
- Before serving, it is recommended to first remove the product from the refrigerator. Thanks to this, the taste and aroma will be more natural. 40-50 minutes of being out of the refrigerator is enough;
- It is advisable to store it in one piece. And cut immediately before use;
- If the cheese is in a plastic bag, you can also put a piece of sugar there. This will help protect against mold;
- You can protect the product from drying out as follows: soak a napkin with a solution of salt water. Squeeze it well so that it remains just damp and the water does not drain. Wrap the product. Then store in the refrigerator. There is no need to additionally pack it in a bag;
- During storage, the product should be protected from foreign food odors. He can absorb them into himself;
- Large pieces of cheese last longer;
- If you bought sliced cheese, you need to change the packaging film after each use;
- You should not store different varieties in the same package;
- It is recommended to open the manufacturer's packaging immediately before use;
- Fluctuations in temperature and humidity are the most common cause of spoilage;
- When a product changes its original color, the surface becomes sticky or becomes covered with mucus, it means it is spoiled. You can't eat this kind of cheese.

How to save?
Cheese is a unique, living product; it is constantly undergoing a process of development, but it reaches the sales counter already ripe, and sometimes even overripe .
This, first of all, affects its taste - the cheese becomes overly spicy, and sometimes acquires a rancid taste.
In addition, this delicacy “loves” to absorb foreign odors , so it is better to store it separately, wrapped in foil or, in extreme cases, in cling film.
The storage periods and conditions for different types of cheese differ , but absolutely all of them suffer from temperature fluctuations and changes in relative humidity.
Storage temperature
At lower temperatures and during freezing , the cheese loses its shape or begins to crumble and separate. In addition, its specific taste properties are distorted.
At temperatures above 10-15°C, the consistency (structure) and taste of the dairy product changes and the progressive growth of pathogenic microorganisms .
Cheeses have long held a place of honor , and the culinary potential of this product cannot be exhausted.
It is distributed everywhere, and from the abundance of assortment on the counter, you can be confused as to which variety or type to give preference to .
Any buyer strives to buy fresh, high-quality and tasty cheese.
To find one, you need to “get acquainted” with the desired product, and it is advisable to do this at the selection stage , so as not to make a mistake with the purchase.
When choosing cheese on the counter, first of all, you should pay attention to how fresh it is and how much time it has left to “live”, i.e. for its expiration dates.
Deadlines by type
factors influence the determination of the shelf life of cheese :
- composition of the product;
- humidity of the product itself;
- the amount of salt it contains;
- the presence or absence of a shell on it.
For cheeses, it is recommended to maintain humidity in storage areas at a level of 85-92% . Extremes of indicators negatively affect the quality of cheese. Thus, very low humidity leads to drying out , and high humidity contributes to deterioration in taste, rotting and spoilage.

Can cheese be stored in the freezer?
Every professional chef will tell you that storing cheese in the freezer is absolutely forbidden. This type of storage causes its texture to become porous and its taste dulled. After defrosting, the product will remain edible, but will crumble. It is only suitable for making soup and filling for baking; it is not suitable for slicing.
The refrigerator is the place for optimal cheese storage. After all, city dwellers are deprived of cellars and closets where they traditionally keep cheese wheels. The refrigerator constantly maintains a temperature of -2–+3 degrees and a humidity of about 80%, which is acceptable for storing cheese products. But even when storing cheeses in the refrigerator, it is necessary to allocate a special place for them - for example, a compartment for vegetables and fruits or the bottom shelf of the refrigerator. These places maintain the required temperature and humidity.
