Whey Protein Concentrate

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.

WPC 34

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).

WPC 80

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.

Taking care of the entire process

Tetra Pak is the only company in the world that can integrate the entire cheese making process, from milk reception, to curd making, wet whey processing, drying and powder handling.
