1, whey protein concentrate (WPC)
Whey powder can be obtained by directly drying whey, in which whey protein is extremely low, generally above 10% and not more than 30%. Whey was clarified, ultrafiltered and dried, and the product was concentrated whey protein. Through different filtration degrees, products with protein concentration between 34% and 80% can be obtained.
2. Isolate whey protein
The separated whey protein is a high-purity whey protein obtained by further processing on the basis of concentrated whey protein, and the purity can reach more than 90%. It is expensive, 2-3 times that of concentrated whey protein, but it is also easier to digest and absorb.
3. Whey protein peptide
Whey protein peptide is the hydrolysate of whey protein and the essence of whey protein, which can participate in the process of muscle synthesis more quickly in the body. It can be seen from the types and functions of various whey protein products that supplementing whey protein is not only of great significance to the general population.
Development of whey protein;
The separation and preparation of Whey Protein Isolation in China began more than ten years ago, and the technology adopted at that time was mainly membrane technology. As early as 1990, the United States used ion exchange to separate whey protein from whey. In addition, bioselective adsorption, affinity chromatography purification and reversed-phase micelle extraction are all new methods to separate whey protein components.
At present, there is no comprehensive utilization technology of whey protein with independent intellectual property rights in China, while foreign technologies are protected by patents, which seriously restricts the development and utilization of whey protein resources in China and the sustainable development of dairy industry. It is understood that China still needs to import a large number of whey products such as desalted whey powder, whey protein concentrate, Whey Protein Isolation and lactose for formula food, candy production and ice cream ingredients every year, which is expensive.
