Liquid filling

Liquid filling is the method used for producing fresh white and Mediterranean cheese varieties like feta and queso fresco. The cheese is packed as a liquid and coagulates inside the final package.

When making liquid filled cheeses, all the ingredients are mixed in a homogenous way and the product can be sold straight after it has cooled. There is no need for ripening on the shelf, which means producers get a quick return on their investment.

When using Tetra Pak’s ultra filtration technology to make liquid filled cheese, manufacturers enjoy a higher product yield than is possible using traditional methods.

​That’s because all the whey proteins are incorporated in the cheese, so you get the same amount of solids but with a higher proportion of whey protein to caseins. In other words, more cheese can be made using the exact same amount of milk.

How does it work? The permeate is forced out of the cheese while the retentate remains (ratio 5:1). Being a closed process, this is also a very hygienic production method, ending up with the product in a hermetically sealed package with a shelf life of 6 to 12 months.
