Selection

Natural is home-made sour cream from the farmer. Such a product will have a creamy flavor, a tender consistency, a high fat content. But the latter property is not entirely suitable for those who follow the figure. However, there are no additives and preservatives in our products, which can not be said about the store products.

In the shops a large assortment is presented. The products are characterized by fat content, additives and cost. Before fermentation, the cream is brought to the required fat content. Caloric content does not always indicate naturalness, that is, 12% of sour cream will be suitable. Whatever the fat content, the product should not be liquid. The quality is a uniform consistency. If there are grains, the manufacturing technology is violated or the storage conditions were inadequate.

But even if the consistency is good, this is not an indicator of naturalness. To improve it, manufacturers often add stabilizers and thickeners to the product. Also in the stores are sold sour cream products, in which there is a plant base - palm oil. Doctors, nutritionists do not recommend using something like that.

You should take into account the prefix "bio" in the name. It indicates that sour cream is enriched with bifidobacteria and probiotics. These substances are considered useful for digestion. All information about the composition and storage must be on the package. It is important that the GOST marking is present, as this indicates the naturalness and observance of the technology of preparation. If the products are made according to specifications, sour cream is not necessarily a harmful compound. Probably, the classical sour cream was diluted with additives, for example, bifidobacteria. Remember that it is important to choose this milk delicacy carefully, and also observe the rules of its storage.
