Whey Powder

Whey Powder

In cheese manufacture, the whey is discarded since storing it in liquid form is impossible for cheese producers due to the fact that its composition is altered. The solution is to transform it into powder.

The whey powder is the result of a process of transformation of fresh milk. The solids, which represent approximately 4% of the total, are separated from the liquid through the processes of centrifuging and concentration, generating a product that is concentrated and easy to store and transport.

The Relat whey powder is sold in 25 kg bags.

Whey powder is largely used in the manufacture of food products for human and animal consumption. It is a raw material in the production of cookies, bread, pasta, ice cream, dairy beverages, isotonic drinks, and modified milk products.

Because of its high protein and amino acid content, milk whey powder is also used in sportsnutrition to aid in weight loss and help in building up lean muscle mass. It is present in protein supplement products, protein bars, and other nutritional supplements.

In animal nutrition, whey powder is important in the manufacture of animal feed.


Recent studies demonstrate that protein from whey powder is rich in essential and branched-chain amino acids, important for growth and tissue repair, especially in muscle tissue. These properties make whey powder particularly beneficial for three target groups: the elderly, athletes, and those seeking to maintain or lose weight.

For the elderly, proteins and amino acids aid in immunization against diseases and help minimize the symptoms of sarcopenia, the degenerative loss of muscle mass associated with aging.

Whey powder is also recommended to those who exercise regularly. Branched-chain amino acids present in whey powder increase protein synthesis and muscle growth during resting periods, in addition to meeting the demand during physical activity.

To those who seek to maintain or lose weight, whey powder protein is also recommended because it plays an important role in controlling satiety. The high content of calcium may also be linked to reducing the accumulation of fat deposits, according to recent clinical studies.

“Several studies show that whey powder protein is more effective than protein from soy, eggs, and meat in suppressing the ingestion of food. For these reasons, incorporating whey powder protein in their diet may be the ideal solution for many consumers interested in a protein-rich diet with a moderate amount of carbohydrates.”
