Do packaged sliced cheeses really contain starch?

Yeah, a lot of sliced packaged cheeses contain starch as an anti-caking agent to keep the slices from sticking together in the package! You usually find it in the ingredients list with names like "potato starch" or "corn starch", and honestly it's a pretty common practice in the food industry. It's not a bad thing, but if you want to avoid it I'd suggest checking the label carefully because there are brands that leave it out.

There actually is starch in a lot of sliced cheese, but not always - it really depends on the brand. I actually noticed this myself when I started really reading the ingredient lists on the products I was buying. It's usually there as an anti-caking agent, basically to stop the slices from sticking together in the package. You'll find it listed as "potato starch" or "corn starch" in the ingredients, sometimes hidden in a super long list of stuff.

What surprised me is that not all sliced cheeses contain it. When I tried ones that were a bit higher quality or from specialty shops, there was often way less of this separating agent, and in some cases absolutely none. It's one of those things that comes down to price and how serious the producer is, not really about laws or actual technical needs. If you want to avoid it, it's better to check the label rather than just trust the brand in general.

There's definitely starch in there, but it's not the absolute rule that some people make it out to be - it really depends a lot on the quality and brand, and some decent slices don't have it at all. Anyway yeah, when they do add it it's specifically to keep them from sticking together, so always check the label if you wanna be careful 👍
