Most cheeses (sandwich, grated, or sliced) don’t always contain...cheese.
To save money and simplify the process, some manufacturers replace milk with whey protein or palm oil.
Such a thing is called cheese product, not real cheese, but this may not be indicated on the label.
Real cheese should be made of natural milk and contain no vegetable fat.
Cheese that contains palm oil crumbles when sliced.
And if you press on it, a dent will remain, and liquid will appear.
As a rule, such cheese doesn’t contain any natural flavoring additives.
