It is very important that the fat content of the final product should not be less than 82.5%. There are many options for butter, for example, sweet cream, chocolate or with different toppings.

How to choose the best dairy product and how to store it?

The first thing you should pay attention to when choosing butter is packaging. It is best to choose the product that will be wrapped in foil, because in this state it retains the maximum amount of nutrients. When reading the composition, pay attention to what is in it should not contain vegetable fats  This is because this component transfers the dairy product from the category of natural to the category of spreads. In addition, it is worth giving preference to oil that is produced according to GOST, and not according to technical conditions (TU). Low quality can be testified to by low price. Low cost, as a rule, is achieved by replacing the dairy components with vegetable ones. It is also advisable to buy a product from well-known manufacturers that value their name and reputation. Although this item is not at all a guarantee of quality. However, even following these simple recommendations for choosing, you can still stumble on a fake, because we will tell you how to determine the quality of butter at home.

First of all, find the answer to the question: “Does butter freeze in the refrigerator and does it crumble!” For a high-quality natural product, the answer should be positive.

Excessive softness indicates only impurities of vegetable oils. Really high-quality product should not contain them. The second indicator, which indicates the naturalness of the oil, is the lack of stickiness. The natural product has a fairly high percentage of fat content, so that it will not leave marks on the packaging. In addition, it is worth paying attention to its color. It should not be too saturated, because this will be evidence of the addition of a dye called beta-carotene.

A simple homemade test that will help determine whether the butter is really and natural is as follows: a tablespoon of the desired product is dissolved in 200 ml of water (1 cup). When completely dissolved, no sediment should fall to the bottom. Water in a glass should acquire a uniform white color.

As for the storage conditions of butter, it should be kept either in the refrigerator or in a dark place, the main thing is that the temperature should not exceed 12 degrees. It is also worth considering that this product has the ability to absorb unpleasant odors, so look near what, you put the oil in the refrigerator.

If you bought a large amount of oil, then the surplus is best stored in a freezer. In fresh air, the product must always be in an opaque oiler.

The expiration date of the product must be indicated on the packaging. In general, the shelf life of high-quality butter should not exceed 10 days when packaging in parchment and 20 days when packaging in foil. The freezer allows you to increase the shelf life up to 2 months.

If you are interested in the question of how to understand that the butter has deteriorated, then everything is very simple. Firstly, it becomes more saturated in color, and also acquires a rather unpleasant odor. As for taste, it becomes bitter. However, rancid butter can still be fixed.

There are types of plant products that have little bitterness initially, and those that get it in the process of oxidation. Substances that have a spicy bitterness in the taste palette include well-known and in demand among the population, linseed and olive oils. They make worthy competition to the usual to use sunflower oil.

From flax seeds

Flaxseed oil is useful when used in food and medicine, but is specific in taste. A small amount of natural bitterness testifies to its quality, but does not contribute to undiluted use.

For salad dressing, it is used in a mixture with sunflower or olive oils, in a proportion of 1/2. Taste bitterness is due to the high content of beneficial acids beneficial for the human body. It can not be fried in order to avoid the complete loss of useful properties.

Regular intake of flaxseed food contributes to:

• prevention of heart and vascular diseases;
• pressure normalization;
• support visual function;
• stabilization of the nervous system;

Color differences are a consequence of the olive processing method. Refined product is cleaned, increasing its shelf life, but reducing utility, and unrefined is not processed at all. It is valuable in preserving the best qualities, but is specific in taste and smell. This is a natural product, which can be of different colors depending on the spin and variety. The presence of dark color and sediment, coupled with bitterness, does not give reason to consider it spoiled.

Corruption can be judged by signs that have appeared during use. For example, color, taste and texture have changed.

How to prevent spoilage:

• do not use after the expiration date;
• for storage choose a dark, cool place;
• do not save for a long time when uncorked.

Do not use it for frying repeatedly - it is harmful. Remember, the presence of herbal ingredients in the daily menu will improve the appearance, well-being and mood.

How to melt rancid butter?

1. If it’s rancid, then it’s better in a trash can !! ! Good luck !! !
   Ghee can be obtained at home, but this is a complex process. To do this, it is best to install a pan with melted butter in another larger bowl, in which the water is brought to a boil. Before putting the oil into the pan, it is recommended to pour a little water, warm it to 70-75 ° C, and then transfer the oil into this water, cut into small pieces. To speed up and evenly heat the oil, mix lightly. When it melts and heats up to 75 ° C, stirring is stopped, add 15-25 g of salt per 1 kg of oil (sprinkling salt on the surface), mix it lightly and leave it alone until the fat is completely separated and clarified. So that the oil does not cool, the temperature of the water in the dishes in which the pan with melted butter is installed is maintained at 80 ° C. After 1-1.5 hours, the separation of fat ends, the fat settles in the upper layer, and moisture, proteins and other substances accumulate under a layer of oil. Then the melted fat is carefully poured into a bowl or the fat is allowed to cool in the cold and harden, after which the fat is removed from the bowl in which the butter was overheated.
2. It seems to me that it will still be bitter. Try to add a few crushed beans when reheating, it may help. Then strain. Beans are placed in sunflower oil so that they do not get rancid.
3. You’ll only lose time - the product received as a result of long torment is thrown away anyway, it will not do anything. Once I bought, without checking for the smell, a bar of rustic oil in the market, brought it home, anticipating how I would spread it on hot bread and eat it. It wasn’t there - she opened the wrapper, and a rancid smell hit her nose. I decided, like you, to save this oil, found several recipes on the Internet to revitalize it and used them all. Absolutely useless work, only a mountain of dishes still have to be washed.
4. Ah, if it was possible to restore peroxides to fatty acids, and these acids (rancidity is precisely because of them) back to glycerol, you could save your oil.
   But alas! Rancid oil is not suitable for food, it is more harmful than saving.
5. not save
6. rancidity of fats is an oxidation that manifests itself in the appearance of a specific odor and unpleasant taste, caused by the formation of low molecular weight carbonyl compounds and due to a number of chemical processes
   There are two types of rancidity, biochemical and chemical
   Biochemical rancidity is characteristic of fats containing a significant amount of water and an admixture of proteins and carbohydrates (for example, cow's oil). Under the influence of enzymes contained in proteins (lipases), hydrolysis of fats and the formation of free fatty acids occur. An increase in acidity may not be accompanied by rancidity. Microorganisms that develop in fats secrete other lipooxidase enzymes, under the influence of which fatty acids are oxidized to # 946; -keto acids. Methylalkyl ketones formed during the breakdown of the latter are responsible for changes in the taste and smell of fat. To avoid this, thorough purification of fats from impurities of protein substances is carried out, storage under conditions excluding the ingress of microorganisms and at low temperature, as well as the addition of preservatives (NaCl, benzoic acid) and antioxidants
   From which the conclusion follows - it will not work, it's like turning rust into iron ...

Getting rid of the bad smell of butter is easy.

We need to take rancid butter, go to the garbage bins and, without any regret, throw it away. If it emits such a smell, then it has deteriorated and you can get rid of it only in this way. For no purpose it is unsuitable, it will only cause harm. It is also not recommended to feed pets, their digestive system is not ready for such a "delicacy".

Spoiled butter can not be eaten!

I did not have to deal with a rancid smell of oil, but with a musty - yes. A yellow plaque is also a sign.

Our grandmothers were not so rich to throw away the product. The most reliable way to "reanimate" subcortical oil is to melt it and boil it.

This is done in an ordinary saucepan, over low heat until completely dissolved, boiled and boiled, and then completely cooled. Three "substrates" are formed in the saucepan. White foam - take it off. Vodichka, "casein" - you merge it. And a little clump of butter grains. There may be an unpleasant odor in the process, but ultimately it should go. The product undergoes a kind of disinfection during heat treatment.

If a lot of oil accidentally accumulates in the house and you doubt that you can save it, melt it right away. Drain the casein. The remaining product, natural ghee, can be stored in the refrigerator much longer.

Oil melted at home is a peculiar product. Some people like it, some don't. But worth a try. A penny ruble saves.
