Period, temperature and storage conditions of whey

You should not eat cottage cheese that has expired, because poisoning occurs quite often, and it is also very difficult to recover. How to store cottage cheese, and can you keep it in the freezer?

Cottage cheese is a valuable edible dairy product. It is rich in calcium and protein. It is especially useful for children, so it is introduced very early as complementary foods. Cottage cheese is made from sour milk. It is an indispensable product when the body is weakened as a result of illness and is used for rapid recovery.

Thanks to the excellent ratio of proteins, fats, carbohydrates, it is absorbed in the body very quickly. Cottage cheese is recommended for children and pregnant women due to the large amount of vitamins, amino acids and mineral salts.

It has been noticed that the dairy product lowers cholesterol in the blood and reduces fat deposits. For this reason, it is recommended to use it for cardiovascular diseases, obesity, and diseases of the musculoskeletal system.

It is important to remember that this is a protein product, so you should not abuse it. Too much protein is bad for the kidneys. Cottage cheese with high fat content increases cholesterol and contributes to obesity.

Terms and conditions of storage

This wonderful product has been known since ancient times. Our grandmothers in the villages managed to store cottage cheese in a cold cellar for up to a week. In winter, when there was already little milk, the cottage cheese was frozen in the form of balls. But more often it was used to make cheeses that could be stored for a long time.

In order to determine the shelf life of cottage cheese, you need to know the characteristics of the product. Full-fat cottage cheese made from selected milk with a fat content of about 16-18%.

Half-fat cottage cheese – 9%; Low-fat cottage cheese is made from skim milk. This cottage cheese is considered the most useful and is easily digestible. The higher the fat content, the shorter the shelf life of the cottage cheese and the limited indications for consumption. At room temperature the shelf life is up to 4 hours.

You need to be clear that the shelf life is very short. This is a quickly perishable product that loses its taste. Externally, it becomes gray or yellow in color and acquires a bitter taste. An unpleasant odor appears. This product should not be eaten.

Specifics of defrosting cottage cheese

Housewives who prefer to freeze the composition should remember the important aspects of preparing it for further use. To defrost the mass correctly, you need to place it in the refrigerator on one of the shelves in the common chamber. The entire manipulation will take at least 10-12 hours, so you need to take care of the manipulation in advance. Any additional thermal effects are strictly prohibited.

The composition cannot even be laid out at room temperature. The only thing that is allowed to additionally influence the process is a damp cloth, which needs to be wrapped around the lump after removing it from the freezer.

If you follow these rules, you can regularly consume nutritious foods with health benefits and without any risk. If there is any suspicion that the product has been damaged, you must immediately throw it away and not try to use it even as an additive to the filling of a pie, cheesecakes or dumplings.

Even under such conditions, it is not recommended to store cottage cheese for more than 3-4 days. In addition, there is a very old approach that, although it will not extend the shelf life of the product, will allow it to remain very fresh throughout its entire life. We take pottery covered with glaze, wash and dry. Pour a layer of coarse salt onto the bottom, place cottage cheese on top, spread on a linen rag, and press down. We soak a piece of cotton fabric in a low concentration saline solution, cover the structure, and tuck the edges. You can place a plate with a slight pressure on top.

Shelf life in the refrigerator

Fresh cottage cheese can be stored in the refrigerator for 2 days. The temperature should not be higher than +8 °C. Temperature changes should not be allowed. Optimum temperature for storage is +2…+5 °C.

With sufficiently good cooling to 0 °C, cottage cheese can be stored for 4 days. Before placing in the refrigerator, it is better to place the product in a clean porcelain or glass cup and cover with parchment or foil. Do not place in metal containers or plastic containers.

For more than 1 day of storage, it is better to make various casseroles, dumplings, and cookies from cottage cheese.

How to determine freshness?

Many people buy cottage cheese exclusively in the store, but there are also those who prefer only the product purchased at the market. In both cases, there is a risk of buying a product that is not of high quality. Let's figure out what you need to pay attention to in order to choose natural and high-quality cottage cheese from all the variety of products.

  1. Package. It must be airtight, so the risk of pathogenic bacteria getting into the cottage cheese will be minimal.
  2. Best before date. Real cottage cheese, according to GOST, can be stored for no more than 72 hours. If this number is higher, then you have a product with additives.
  3. Name on the label. According to the law, a product containing starch and vegetable fats cannot be called cottage cheese (such products are called differently - cottage cheese, curd mass or curd product).
  4. Ingredients on the label. The name “cottage cheese” must be indicated, as well as the number of lactic acid bacteria.
  5. Color. Natural cottage cheese must be white or white-cream.
  6. Price. It cannot be very low, since a lot of milk is used to make cottage cheese.

When buying loose cottage cheese, pay attention to its color, smell, taste and structure.

  • The smell is neither sweet nor sour.
  • Taste – without acid and bitterness.
  • The structure of the cottage cheese must be crumbly; it is this property that will help distinguish real cottage cheese from the curd mass.

At home, it is possible to check cottage cheese for the presence of the following additives:

  • Starch. If you drop a drop of an alcohol solution of iodine on the cottage cheese and it turns blue, it means that the product you purchased contains starch.
  • Vegetable fats. To check, place a small amount of cottage cheese on a plate and leave in a warm place for one day. If the product dries and becomes crusty, no sour smell appears and no yellow spots form on its surface, then the cottage cheese is natural. If everything is the other way around, it means this is a fake.

Storing in the freezer: is it possible to store cottage cheese in the freezer?

You can store cottage cheese in the freezer for up to 1-2 months:

  1. The cottage cheese is placed in a glass container. Can be frozen in special cellophane freezer bags.
  2. Cottage cheese frozen to -35 °C retains its original properties for a long time, up to 2 months.
  3. When stored below -18°C, freshness lasts only 2 weeks.
  4. Be sure to mark the date on the packaging when you put it in the freezer. Be sure to consume within the above time limits.
  5. Only fresh product is used for freezing.
  6. You need to lay it out in portions of 100-200 g. You can make balls and wrap them in foil or take thick bags to prevent air from entering.
  7. A prerequisite is the commercial proximity. For dairy products - cottage cheese, butter, ice cream - there must be either a separate shelf in the refrigerator or a drawer. Do not store together with frozen fish or meat. They must be stored separately from each other.
  8. The fast freezing method is used. You can keep dumplings and cottage cheese pancakes in the freezer. These products are stored for 2 weeks, then the taste deteriorates.

How long can cottage cheese be stored?

In ancient times, cottage cheese was more natural, and there were not many methods for storing it. The simplest and most effective method has long been to wrap it in a rag soaked in water and then store the mass in a dark, cool place. Naturally, no one could guarantee compliance with strict sanitation standards and temperature stability, so the product quickly became unusable. Fortunately, today we have a refrigerator, and some manufacturers do not hesitate to use preservatives to allow long-term storage and transportation of cottage cheese. But we will only consider the issue of preserving the natural product.

Cottage cheese itself can be stored in the refrigerator for an average of 48 hours, after which the likelihood of spoilage greatly increases. However, it happens that cottage cheese lasts even three days at a stable temperature of +8 degrees! In exceptional cases, you can resort to light freezing of the product. Then it can lie for an additional 24 hours, but the temperature should not be around 0 - +1 degrees. Storing cottage cheese prepared at home involves using cooking foil or a plastic bowl. The product is wrapped or tightly closed in a container.

If you are not a particular fan of curd products, you can resort to deep freezing. Of course, this is not highly recommended both among housewives and eminent chefs, because a certain part of the qualities of cottage cheese is lost under such influence. To ensure the required level of freezing, your freezer must produce a temperature of at least -35 degrees Celsius. In this form, it can lie for quite a long time, but its defrosting before use should not be instantaneous. If possible, spread the temperature drop of the product over 12 hours. This is done by transferring the cottage cheese to the bottom shelf of the refrigerator - away from the freezer. Fortunately, cottage cheese frozen to this state does not need additional processing, which is a big plus for those same bachelors. With dishes that include cottage cheese, the above rules are no exception. For example, if you wanted to save cottage cheese for a long-term cottage cheese diet, then this is a very good option. They cannot lie in the refrigerator for a long time, but in the freezer they will last as long as needed.
