Whey protein (whey, protein)
Known as the "king of protein", is a protein extracted from milk, with high nutritional value, easy digestion and absorption, contains a variety of active ingredients and other characteristics, is recognized as one of the high quality human body protein supplements.
Source:
Whey protein is extracted from milk. 87% of the milk is water and 13% is milk solids. In the
milk solids, 27% is milk protein, only 20% of whey protein is whey protein, and the remaining 80% are cain, so whey protein content in milk is only 0.7%, which shows that it is precious.
pulldownCharacteristic：
First of all, whey protein has the highest nutritional value in various proteins. Generally speaking, the esntial amino acids are complete in variety and content, and can provide the protein needed by the human body. They can be called复活节是什么意思
high-quality proteins, also known as complete proteins. The
concept of esntial amino acids is mentioned here. Esntial amino acids are amino acids that are esntial to the body but are not synthesized by themlves and must be taken from food. In plant proteins, only soy proteins are complete proteins, but soy proteins are less absorbent than good animal proteins. Whey protein belongs to high quality complete protein and animal protein. It contains 8 kinds of esntial amino acids,
and the reasonable ratio clo to the human demand ratio, human growth and development, an anti-aging life esnce.
Second, whey protein is more easily digested and absorbed. The whey protein in breast milk contains 60%, and cain contains 40%. Therefore, the infants who drink milk are less soft and less. In addition, whey is rich in cysteine and methionine, which maintain levels of antioxidants in the body. Many experimental studies have shown that whey protein concentrate promotes humoral and cellular immunity, stimulates the body's immune system and prevents the development of chemically induced cancers. So whey protein is a very good immune enhancing protein.
Third whey protein contains low levels of fat and lacto, but it contains beta - globulin, alpha lactalbumin, immunoglobulin, and many other active ingredients. It is the active ingredients that make whey protein have many of the health benefits of the human body, so it is considered to be one of the sources of good protein for the human body.
From the nutritional point of view, the source of animal protein foods contain harmful exce
ss saturated fat, cholesterol and other harmful substances, easily lead to excessive consumption
of body fat and cholesterol, which leads to the occurrence of cardiovascular dia. By taking protein powder, the problems can be avoided while the protein is added. In addition, it is easy to take, attract a high utilization rate, can reduce the burden on the stomach, so protein powder is the best choice for our protein supplement, and whey protein is the primary consideration of our choice of protein powder.

riskoffWith the continuous development of product technology and the increasingly fierce competition in protein products, whey protein products are gradually diversifying,
Whey protein concentrate, whey protein isolate and whey protein products have been added to the market.参加英文
1, concentrated whey protein (WPC)
Whey powder can be directly dried, whey protein which is very low, generally 10 percent, not more than thirty percent. Whey protein is concentrated whey protein after clarification, ultrafiltration, drying and other process. Depending on the degree of filtration, products with varying protein concentrations ranging from 34-80% can be obtained.
2 isolate whey protein (WPI)
Whey protein isolate is a high purity whey protein obtained by further processing on the basis of concentrated whey protein. The purity of whey protein is above 90%. It is expensive, 2-3
times the concentration of whey protein, but it is also easier to digest and absorb. The real beauty of isolated whey protein is its nutritional value, it has high levels of quality protein, can provide high quality protein needed for certain patient populations such as infants and. In addition, bioactive compounds such as alpha lactalbumin and beta lactalbumin, lactoferrin and immunoglobulin, which parate whey proteins, have injected fresh vitality into the market.恋爱假期下载
3 whey protein peptide
Whey protein peptide is the hydrolysate of whey protein, the esnce of whey protein, which can participate in the process of muscle synthesis more quickly in the body.

From the above various types and functions of whey protein products, we can e that the whey protein supplement is not only for the general population is of great significance, also has important significance for people to fitness enthusiasts activity and engage in a variety of different types of athletes or. Becau the demand for protein is higher in sports than in the population, and the rate of protein synthesis increas after exerci, they need to supplement the high quality proteins which are easy to absorb. Whey protein becau of easy digestion and absorption characteristics, synthesis of proteins can rve as fast body raw materials; at the same time, any kind of protein whey protein concentrate than currently studied has a higher biological value, so whey protein behoove become athletes training necessary nutritious food.
