Reconstituted milk: features and differences from natural
Milk is one of the most popular and beneficial components of the human diet, from birth to old age. It contains many useful vitamins and minerals, and the price of this product is not too high. Unfortunately, the shelf life of a fresh product is short, so in stores you can most often find pasteurized milk in bottles or bags.
On the packages you can find such designations as “whole”, “normalized” and “restored”. Many try to avoid the product reconstituted from dry powder, believing that it contains harmful chemicals. In fact, the composition of reconstituted milk practically does not differ from other types of milk displayed on the store shelf.
What it is?
Reconstituted milk is a drink made from a mixture of purified water and dried milk powder. Recovery means that the dry product, formerly a liquid, is restored to almost its original state. Such a powder is obtained by spraying and drying at high temperature conventional milk drops. The dry version is much easier to store and transport than regular white liquid or frozen lumps. At the same time, the powder retains almost all useful trace elements and vitamins that are part of whole milk.
For the first time, a dry product from a liquid was obtained by physician Krichevsky, who evaporated moisture from solutions under the influence of very high temperatures. Today, the dry product is among the many infant formulas, non-alcoholic cocktails, ice cream and many culinary recipes. In this form, milk is delivered to those regions in which the cultivation and grazing of cattle is not possible due to climatic conditions and terrain features. Milk is imported into them in the form of a white powder. Then, at local enterprises, it is diluted with water and the restored product is delivered to stores.
Benefit and harm
Despite the biased attitude of buyers, milk powder practically does not differ from a natural product. As a result of processing, it loses only a small percentage of its nutritional value, leaving useful microelements and most of the vitamins in its composition. In terms of cholesterol content, both drinks are exactly the same, but the restored one also does not need to be boiled.
Powdered milk contains trace elements such as potassium and magnesium, phosphorus, sodium and, of course, such an amount of calcium that is not found in any other product. Its nutritional value is about 450 kcal per 100 g of dry matter. This amount of powder contains 25 g of protein, 25 g of fat and 40 g of carbohydrates.
In addition, it contains about 1 g of organic acids, 15 g of saturated acids, and 38 g of di- and monosaccharides.
Reconstituted milk has such useful properties as:
- the formation of immunoglobulins as a result of drinking a high-protein drink contributes to the fight of the human body with lung infections;
- in addition, protein is necessary for athletes and people building muscle mass; reconstituted milk is most often prepared from skimmed raw materials, therefore it is a diet drink and is useful for losing weight;
- the daily rate of vitamin B12 is useful for anemia, problems with the heart, blood vessels and blood pressure;
- high calcium content promotes the growth and strengthening of nails, hair, teeth and the entire skeleton; calcium is an excellent prevention of osteoporosis and joint problems;
- powdered milk has a high benefit for vision and general well-being, helps to cope with insomnia and reduces migraine headaches; it contributes to the normalization of the development of the child, has an anti-rachitic effect in the development of the fetus in the womb, therefore it is useful for pregnant women;
- such a product normalizes high acidity, helps with heartburn and is generally absorbed better than usual;
- white nutritional powder is included in many recipes for home and industrial cosmetology; masks and creams are made with it, added to baths and decorative cosmetics.
Like any other product, milk powder has its contraindications.
- Do not abuse it in case of poor lactose tolerance and in old age. It should be excluded from the diet of those suffering from allergies and people with deposits of calcium salts in the joints.
- The manufacturer of the product must be carefully selected. Animals grazing in areas with poor ecology produce milk filled with toxins.
- It is necessary that the manufacturer carefully observe the proportions when the dry powder is reconstituted with water.Their violation will turn a diet drink into a real high-calorie bomb, which will contribute to the formation and deposition of excess fat mass on the human body. It is best not to drink such milk at night, since the casein, which is part of the composition, is processed for at least 4-5 hours.
Classification
Varieties of a dairy product depend on the type and condition of its original raw materials, that is, dry powder. Reconstituted milk can be made from several components.
- SC (dry whole). This powder is more nutritious and contains more fat. Its calorie content can reach 500-550 kcal per 100 g.
- CO (dry fat free). This powder has a longer shelf life due to its low fat content. Its nutritional value does not exceed 380 kcal per 100 g of dry matter.
- SB (dry instant). This is a mixture of natural fresh product and fat-free, from which the liquid has been evaporated. It is this type of powder that is most often used for baby food and other instant products.
Production features
In the domestic industry, the production of normalized milk is most often carried out in two stages. At one facility, a dry product is obtained from fresh raw materials, then it is transported to the desired region, and then the product is restored and packaged in bottles or bags at local production. The whole process is a sequence of several actions.
- Normalization. To bring milk from different animals to the same fat content, it is mixed and adjusted to the desired percentage. To reduce fat, add purified water, and to increase fat cream.
- Pasteurization. Milk is heated to completely rid it of possible viruses and lactic acid bacteria. If you leave beneficial bacteria in the composition, the shelf life of the finished product will be no more than 48-72 hours.
- Thickening. The product is divided by fat content and boiled. If you add granulated sugar at this stage, you get the usual condensed milk. After thickening, the milk is brought to a homogeneous consistency.
- Drying. In special machines, splashes of condensed milk are atomized and exposed to high temperatures. The remaining sediment in the form of a white powder is collected and packaged in wholesale and retail containers.
- Transportation. Powdered milk is transported directly to stores or to the warehouse of a local manufacturing plant.
- Recovery. The powder is diluted with purified water in the required proportion and poured into tetrapack and plastic. The finished product is sent to the shelves of supermarkets and local shops.
How to distinguish a product from a powder from a natural one?
Respectable manufacturers always indicate on the packaging of the product from which raw materials the milk was produced. However, you can often find containers with the inscription "whole", which is made from the same powder. It is simply impossible to determine the taste or color of a powder without special laboratory equipment. However, there are some recommendations that can help you choose the right product.
- One of the indicators of natural milk is high cost. The reconstituted drink has a long shelf life, it is easier to store and transport, so it is cheaper than whole. However, the most expensive milk on the counter can also be reconstituted. Oddly enough, but foreign dry raw materials are more expensive than domestic natural products.It is best to choose products of medium and high prices, as well as carefully study the composition.
- One of the indicators of the naturalness of the drink is the inscription on the package or bottle. “Recommended for children aged 0 to 6.” Only manufacturers of high quality whole milk have the right to write this information on their products. In addition, the milk itself should not contain a reddish or orange tint. You can check this by simply bringing ordinary white paper to a glass of liquid.
- Another way to check the purchased drink is do a simple experiment. It is necessary to pour a small part of the milk into any glass container, and leave it on the table for 20-24 hours. If it has not turned sour during this time, the product is made from powder.
It is worth being 90% sure that the milk is reconstituted if it was produced in Siberia or the Far East. In these regions, the livestock sector is practically undeveloped, and the climate does not allow grazing large herds of cattle.
Despite all the recommendations, sometimes it is simply impossible to choose whole milk on the counter, because it is not there. In this case, you can safely buy restored, because in its composition and benefits it is practically in no way inferior to natural, and in some ways it can even surpass it.
