▷ Milk Powder and Whey Powder - Practical or Vitaminless?


All about milk powder and whey powder

Easier and longer storage by removal of water.

Milk powder is a product that is made by removing water from the milk. For many people, however, the question arises, which advantages are connected with this process and the result of it. The sense and purpose can initially be limited to the economic component: Milk and whey powder can be stored to save space and are longer lasting than fresh milk. In addition, the products do not have to be stored refrigerated. But there are also many other interesting aspects to be mentioned in connection with dairy and whey powder. Is milk powder now extremely practical or is it vitaminless? These questions and aspects will be discussed in more detail below.

The production of milk powder

In the case of milk powder, a distinction must first be made between two different types, namely whole milk powder and skimmed milk powder. In general, two different methods are used to extract the water from the milk. These are on the one hand the spray drying and on the other hand the drum drying. First, however, the milk must be cleaned and pasteurized. In addition, for the production of skimmed milk powder, the fat content of the milk must be reduced. Furthermore, the milk is heated, and this process is longer and stronger in the production of whole milk powder. Here the fat content of the milk is 3, 5%. When the method of spray-drying is used for drying, the milk is sprayed into a room with hot air and pulverized thereby. In contrast, drum drying initially produces milk concentrate, with a dry matter of 30-35%. This is then applied to hot drying rollers and loses most of the remaining water in a short time. The solid residues are then removed from the rolls, crushed, cooled and stored. In comparison to spray drying, drum drying is the more favorable process.

The production of whey powder

The production of whey powder behaves quite similar. Again, the two mentioned methods are used for drying. Whey is a waste product of milk, which is produced during cheese production. Here is to distinguish between sweet whey powder and sour whey powder.

The use of milk powder

Milk powder is used in many areas. These include u. a. industrial purposes. So the powder can be used for the production of dairy products such as cheese or yoghurt. Milk powder is also used in the production of confectionery and bakery products. So it can be used for example for the thickening of pudding. Often it is also used for the production of low-calorie foods for diets or for baby food. Of course milk can also be made from milk powder by simply adding water to the powder. Furthermore, the powder is also used in science, especially in biochemistry.

The use of whey powder

Whey powder is also used in the food industry. So it is particularly popular in sports for the purpose of muscle building and muscle regeneration. For this, the powder can be prepared and consumed particularly well as a shake. Another example of the use of whey powder is pig fattening, where it is used as feed.

Differences between milk and whey powder

There are differences especially in the nutritional values of milk and whey powder. For example, 100 g milk powder contains about 49.4 g carbohydrates. In contrast, 100 g of whey powder contains about 68.2 g of carbohydrates. Also with the proteins there are larger deviations. For example, 100 g of milk powder contain about 35.3 g of protein, while whey powder contains only 11.6 g. The fat content is slightly higher with 2, 9 g per 100 g whey powder than with milk powder. Here it is only 1 g per 100 g of powder. With a lactose content of about 70%, the whey powder is particularly unsuitable for people with a lactose intolerance (lactose intolerance). However, milk powder is not an alternative.

Is whey powder useful in the diet?

Particularly suitable within a diet is the whey powder. Often it finds supplemental application in the form of whey drinks. In this context, the commercially available powder is usually provided with additional nutrients and vitamins. However, it is recommended to replace only one meal with one such whey beverage, as whey is still relatively low in nutrients. However, since the whey powder is quite low in calories, this can easily replace a high-calorie meal in the diet. In addition, whey drinks are good for digestion and have a positive effect on the feeling of hunger. Also for the fat burning is whey powder promoting and therefore particularly popular in weight training. Whey shakes are often consumed here. The reason for this is that the protein contained in the whey is absorbed by the body well and quickly. As a result, the body does not fall back on the body's own muscle reserves.

Criticism of milk powder

Often criticized is the high energy consumption in the production of milk powder. Related to this, also based on the high heat impact, the vitamin loss is partly criticized during manufacture. In addition, tests by Stiftung Warentest have found some pollutants in some milk powder products as baby food. On the whole, however, the reviews of the products are positive. Particularly critical for whey powder, but also for milk powder, is the above-mentioned unsuitability for people with lactose intolerance.
