Whey protein concentrate
Sweet whey is generated as a dilute liquid by-product of cheese making. It contains lactose, proteins and minerals. Sweet whey can be fractionated using membranes.
The most common product using this process is a liquid stream that contains at least 34% dry matter protein. The concentrated form is spray dried into a powder, often referred to as 34, or 34% whey protein concentrate (WPC).
This product is the same as WPC 34, except that it contains at least 80% dry matter protein and requires additional membranes and a technique called diafiltration.
Tetra Pak is the only company in the world who can take integrate the entire cheese making process, from milk reception, to curd creation, wet whey processing, drying and powder handling.
