The King of Sports Nutrition: Whey Protein

2018-12-13 15:06 Thursday


According to Euromonitor 2017, protein powder is the category of sports nutrition products with the highest market share. In Western Europe, 65% of sports nutrition products are protein powders, and the main raw material for protein powder is whey protein.

Whey Protein

Whey protein primarily comes from human and animal milk, which are of high nutritional value. Most sports nutrition products extract whey protein from cow's milk. Milk protein is a safe natural protein, containing β-lactoglobulin, α-lactalbumin, immunoglobulin and other active ingredients.

Whey protein is not only nutritious, but also has diverse functions, improving immunity, mineral absorption and muscle building. The branched-chain amino acid in whey protein provides a lot of energy for the human body, thereby promoting the formation of muscle tissue. Therefore, products containing whey protein have always been favored.

Whey proteins can be divided into the following categories: concentrated whey proteins, isolated whey proteins, and hydrolyzed whey proteins, depending on their purity.

Whey Protein Concentrate

Whey protein concentrate has a low purity ranging from 35% to 38%. Because it contains lactose wait as a material, whey protein's absorption rate is lower, and it can lead to symptoms such as loose bowels.

Whey Protein Isolate

Whey protein isolate is separated by filtration and drying to remove lactose from concentrated whey protein. Therefore, the purity of whey protein isolate is higher than that for whey protein concentrate, generally in the range of 88%.

Whey Protein Hydrolyzed

Hydrolyzed whey protein has the highest purity, reaching 96%. Whey protein hydrolyzed is reprocessed, with the highest purity and absorption, making it the best raw material for protein products.
