Tangent on tangent - in addition to the antifungal there is also anticaking agent (nothing crazy, often some type of flour) that noticeably changes the mouthfeel of cheeses that come pre-shredded. If you notice a grainy texture in your food, try grating it off a brick instead!
Yeah, especially for things like cheese sauces I find that it's better to just grate it yourself. It will _not_ melt correctly otherwise, and the additives mess with sauces more than you'd think.
Never came close to anything resembling a well melted, good tasting sauce.
