Whey Protein Concentrate 80% WPC Wpi 90% Whey Protein

Whey protein is a protein extracted from milk. It has the characteristics of high nutritional value, easy digestion and absorption, and contains a variety of active ingredients. It is recognized as one of the high-quality protein supplements for the human body.

Whey protein refers to the protein dissolved and dispersed in whey, accounting for about 18% to 20% of milk protein, and can be divided into heat-stable and heat-unstable whey proteins. When the whey liquid is boiled at pH = 4.6-4.7 for 20 minutes, a type of protein that precipitates is heat-unstable whey protein, mainly including lactalbumin and lactoglobulin; the protein that does not precipitate is heat-stable protein, which accounts for about 19% of whey protein. When saturated ammonium sulfate or saturated magnesium sulfate is added to neutral whey for precipitation, the protein that is dissolved but not precipitated is lactalbumin, and the protein that can precipitate but not dissolved is lactoglobulin.

 

The elderly are prone to negative protein balance because protein catabolism is greater than anabolism. In addition, the protein intake in the elderly's daily diet is usually low, and the digestion, absorption and utilization rate are reduced, which is more likely to aggravate this negative balance. This is very unfavorable for maintaining the muscle strength and immunity of the elderly. Therefore, it is recommended to supplement high-quality protein that is easy to digest, absorb and utilize. Whey protein is a type of high-quality protein with high nutritional value and easy to digest and absorb. In addition, whey protein is rich in immunoglobulins, lactoglobulins and other ingredients, which can improve the immunity of the elderly and enhance physical fitness. Whey protein is also a good source of calcium. Some whey protein products can provide 500-800 mg of calcium per 100 grams, which helps maintain the bone health of the elderly and reduce the risk of bone mineral loss and fractures.

Exercise not only consumes a lot of energy, but also aggravates protein catabolism, and even negative protein balance may occur. Therefore, protein intake should be increased, especially the intake of high-quality protein. For example, increasing the intake of whey protein appropriately plays an important role in replenishing protein loss during exercise, increasing muscle strength, promoting hemoglobin synthesis, and eliminating fatigue. Since whey protein is rich in branched-chain amino acids, it can promote muscle protein synthesis and is more suitable for the needs of sports and fitness people.
