Butter: expiration date and storage rules
Butter is a truly unique product that not only adds a characteristic milky taste to the dish, but also brings great benefits to the human body. Most of the refrigerators in our country can boast of having this product. For many, the issue of its storage is not a simple curiosity, and therefore we will consider the issue of the rules for storing this dairy product in this article.
Signs of a quality product
To date, there are several features that determine the quality of this product.
- The fat content should be no less than 72 and no more than 82 percent. The maximum fat content is typical only for ghee - 99 percent.
- A quality product will necessarily comply with state regulations (52253-2004 and 32261-2013).
- The product should have a characteristic milky and mild taste. All kinds of industrial impurities should be absent.
- High-quality butter has a light yellow tint.
- Heat treatment contributes to a change in consistency. The product in this case begins to melt.
- Being in a frozen solid state, the butter should not crumble when it is cut.
- The price of this product a priori cannot be low, since its prime cost is rather high. This is due to the fact that the production of 1 kg of butter requires about 20 liters of whole milk.
- If you press your finger on slightly softened butter, then a few drops of water will definitely appear on its surface. But this is provided that the product is of high quality.
Expiration dates
The production and storage time of butter is determined by state quality standards. According to them, it is permissible to store this product for no more than thirty days, after which the product becomes unfit for consumption. Imported analogues, as a rule, have a longer shelf life. This is due to the fact that it takes a considerable amount of time to transport this dairy product to another country.
Therefore, butter manufacturers add various industrial additives called preservatives to the composition. As a result, the shelf life of the product is increased to 12 months. According to statistics, few people decide to buy such products.
The optimal and acceptable shelf life of this product are: ten days in parchment paper and twenty days in foil. When purchasing a briquette of butter in the dairy department, pay attention to the production date. In particular, if you are attracted by the low cost of the product. Most likely, the shelf life of such butter is coming to an end, and the store arranges promotions. It is worth noting that Butter that was made in the summer often has a longer shelf life than butter made in the winter.
The product can be stored for a long time if the storage temperature is very low, that is, in the freezer. Not in the freezer, but at room temperature, the product is stored for no more than a day.
Packing material and storage containers
There are several factors that affect the duration of storage in the refrigerator. Packaging material is one of them. The most optimal options include capped foil. This packaging material is famous for being inaccessible to light. This feature of the packaging does not allow the dairy product to oxidize. Another good option is parchment paper, the matte variety of which also blocks light.
When purchasing, be sure to visually evaluate the packaging of butter. Deformed briquettes indicate that, most likely, the dairy product was defrosted. For home storage, an ordinary oiler is an ideal container. It is advisable to choose an opaque oiler. And in no case do not purchase a container made of glass. Give preference to ceramics, wood or food-grade plastic. Place the oil container on the shelf in the refrigerator compartment where the temperature is the lowest.
Few people know, but butter perfectly absorbs the smells of products that are nearby. Therefore, you need to correctly distribute the location of the products. Do not put products with pronounced odors next to butter.
Freezer storage
This dairy product can be frozen. At a temperature of no more than eighteen degrees below zero, butter can be stored for twelve months.To avoid repeated freezing or repeated defrosting, divide the product into several parts. This will allow you to use only the amount of product that you need.
Batch freezing is a fundamental factor in the storage of any product that undergoes long-term storage in the freezer.
Do not forget that natural products differ from industrially produced analogues in that they are thawed for no more than thirty minutes.
Storage without cold storage
There is a storage method without the use of a freezer or refrigerator. They are known to few people and will be useful only if there is no refrigerator, there are problems with the electrical network, or you are in the country or in the village. This method involves the preparation of brine. You will need twenty grams of salt per liter of clean drinking water. Butter is cut into small pieces, the weight of each should not exceed more than two hundred grams. Also, all cut pieces will need to be wrapped in parchment paper.
Then carefully place all pieces of butter wrapped in parchment into an enamel container. Pour the previously prepared brine on top and create a press effect by pressing the briquettes with oil with some heavy object. It is recommended to place an enameled container in a cellar or basement, where, as a rule, a rather low temperature regime is maintained. It is also permissible to store briquettes with butter in three-liter jars or in any other glass container. Brine and two teaspoons of table vinegar (five percent) are poured over the packed pieces of butter.
Characteristics of a spoiled product
Butter whose expiration date has expired is characterized by the presence of several signs. Thanks to them, you can determine that this product is not worth using. Below are a few of them:
- a spoiled product is characterized by a pronounced cutting aroma;
- spoiled butter tastes bitter;
- after the expiration date, the shade of the product changes from light yellow to bright yellow.
When butter expires, changes begin to occur inside the product. The dehydrated upper surface of the oil begins to oxidize intensively. The oil acquires a characteristic bright yellow hue. The once-pleasant aroma of fresh oil begins to give off rot.
Taste qualities also leave much to be desired - the product acquires a bitter and extremely sugary taste. This phenomenon is called staff.
Ways to restore damaged oil
By and large, it is most desirable to get rid of an expired product immediately. However, if such a need still exists, the following are ways to restore spoiled butter.
- Dip a block of butter in milk (preferably high fat) for ten to fifteen minutes. Then wash the butter in a deep bowl of cold water.
- Heating, a method you've probably heard of. Melt the spoiled stick of butter in a heavy-bottomed saucepan. Crumble a loaf or white bread crust into the butter. Also, sometimes small pieces of apple are added and the resulting mass is carefully filtered.
- An expired butter briquette is washed in a deep bowl with cold water and then generously sprinkled with salt. After the remnants of unabsorbed salt are removed with carrot juice.
- Process the butter with one tablespoon of baking soda dissolved in clean water. After that, thoroughly rinse the oil cake in cold water, and sprinkle the surface of the product with fine-grained salt.
What to look for when purchasing?
First, take some time to study the packaging. Read the ingredients of the product, with the indicated expiration date, date of production and nutritional value. For high-quality and natural butter, only cream and milk can be used in the manufacture. You may encounter the presence of salt in the composition, but other ingredients should not be observed.
The content of even a small amount of vegetable fats in a briquette is evidence that this is not a natural product, but its surrogate (in other words, a substitute). This will be confirmed by the relatively low cost and deviations from state quality standards. If you have a choice between sweet (based on pasteurized cream) and sour butter (based on cured cream), choose the latter, as it has a much longer shelf life.
