It can be divided into two parts: heat stable whey protein and heat unstable whey protein. When the whey solution is boiled for 20min minutes at pH = 4.6 ~ 4.7, a kind of protein that precipitates is thermally unstable whey protein, mainly including lactalbumin and lactoglobulin.
Protein, which does not precipitate, belongs to 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 which is dissolved but not precipitated is lactalbumin, and the which can be precipitated but not dissolved belongs to lactoglobulin.

For normal people, if you have the habit of drinking a glass of milk every day, it is enough. For those who drink milk and cause gastrointestinal discomfort, you can choose whey protein powder to supplement it. The daily amount of protein we need to supplement is 10 to 20g on average. Generally, when taking whey protein powder, add 1 to 2 spoonfuls in food or directly brew with warm water.
The ratio of daily protein required by normal adults is: 1 kg body weight requires 0.8 to 1 g protein. Generally speaking, men are 70 to 80 grams, and more 10 grams is added during strenuous exercise.
