Whey Protein Concentrate (WPC) and Whey Protein Isolate (WPI)
What are whey protein concentrate and whey protein isolate powders? What is the difference?
First let’s look at what whey protein is:
Whey protein is a precious protein separated and extracted from milk using advanced technology. It is known for its many advantages such as high purity, high absorption rate and the most reasonable amino acid composition. Referred to as the "king of protein".
Whey protein is not only easy to digest, but also has high biological value, high conversion rate, high protein efficacy ratio and high utilization rate. It is a high-quality protein and is recognized as one of the high-quality protein supplements for the human body. Milk is composed of 87% water and 13% milk solids. 27% of milk solids are milk protein, only 20% of milk protein is whey protein, and the remaining 80% is casein, so the content of whey protein in milk is only 0.7%
Classification of whey protein powder:
1. Whey protein concentrate wpc powder
After drying the whey directly, whey powder can be obtained, in which the whey protein content is extremely low, usually more than ten percent and no more than 30 percent. The product obtained after whey undergoes clarification, ultrafiltration, drying and other processes is whey protein concentrate. Depending on the degree of filtration, products with protein concentrations ranging from 34-80% can be obtained.
2. Whey protein isolate (WPI)
Whey protein isolate is a high-purity whey protein obtained through further processing on the basis of concentrated whey protein, with a purity of more than 90%. It is expensive, 2-3 times more expensive than whey protein concentrate, but it is also easier to digest and absorb.
The real beauty of whey protein isolate is its nutritional value. It has high content of high-quality protein, which can Provide high-quality protein for certain groups with specific needs, such as infants and hospitalized patients. In addition, the bioactive compounds contained in whey protein isolate, such as α-lactalbumin and β-lactalbumin, lactoferrin and immunoglobulins, have injected fresh vitality into the market.
At the same time, whey protein isolate also contains a large amount of BCAA (branched key amino acids), which can be extremely effective in supplementing the nutrients needed by muscles. At the same time, hypoprin is a precursor for the production of antibodies in the body. It is currently the most suitable nutritional supplement for increasing muscle growth and restoring health to patients.
3. Hydrolyzed whey protein powder
WEIDER hydrolyzed whey protein powder (100% premium hudrolyzed whey protein) that has been hydrolyzed is a high-protein food fortification that is easier to absorb than unhydrolyzed whey protein powder; hydrolyzed protein It loses the ability to trigger allergies in humans and is suitable for people of all ages and can be used in low-allergen infant formula.
