Smooth texture, that doesn't break (separate into oil and protein) with heat. Those ingredients and/or similar ones are principally responsible for what makes "processed cheese" processed. So think Velveeta or Kraft Singles, but potentially made with higher quality cheese.

Good quality hard and semi-hard cheese made with rennet should melt and not separate. E.g. gruyere, cheddar, gouda or emmental, particularly the protected varieties. If good cheese didn't melt it would probably not be considered an attractive characteristic and it would not be something people bother to try and simulate with additives.

  You can of course melt almost any unprocessed cheese without separating it, but they all split if overheated and don't behave well with added liquid (e.g. in sauces) without assistance from some additive. Processed cheeses with these "melting salts" have categorically different melting characteristics, they aren't trying to merely simulate regular cheese; they start as out as regular cheese after all.

    >> You can of course melt almost any unprocessed cheese without separating it, but they all split if overheated and don't behave well with added liquid (e.g. in sauces) without assistance from some additive. That is really not my experience. Are we both talking about good to high quality European hard and semi-hard cheeses, especially PDO varieties? Edit: come to think of it, I should probably also check what you mean by "overheated". E.g. in Greece, where I come from, saganaki [1] is a signature dish that consists of a slab of graviera or kefalotyri (hard cheeses, in the alpine style) deep-fried in batter. I've had my share of sagnaki and I've never seen one break and separate in the way you say. ______________ [1] https://en.wikipedia.org/wiki/Saganaki https://en.wikipedia.org/wiki/Saganaki

      Yes, some preparations even rely on cheese separating. E.g. parmesan tuiles, even when prepared with PDO Parmigiano-Reggiano or Grana Padano can be seen breaking and expelling their fat before crisping. Every preparation of onion soup I've seen, even when using proper Gruyere or Comte, has an oil slick on top that has been expelled from the cheese. The cheeses used in saganaki (which I've never seen battered, only fried directly) weep oil before they melt. Processed cheeses, on the other hand, will typically burn before they break. And they flow very differently when melted.

        In that case I have no idea what you're talking about :) I think we may be talking about different things. I don't eat processed cheese so I don't know how it behaves. A quick search on the internet tells me that processed cheese can be melted to the point it is poured. It is then used in sauces. For sure, you can't pour real cheese. So I'm talking about the kind of melting you see, e.g. in a raclette: https://www.youtube.com/watch?v=U5U1crD18iM https://www.youtube.com/watch?v=U5U1crD18iM Yes, real cheese will weep when you heat it but that's not "oil". Depending on the age of the cheese, some of it is whey and the rest is butterfat. But your description of "breaking" makes it sound like you expect cheese to cleanly separate in a puddle of butterfat and a chunk of protein, whereas real cheese will melt into a viscous fluid. That is - if it's cheese that melts in the first place. For instance, feta or haloumi don't melt, etc. I suspect I might misunderstand your description of "break" though. Regarding saganaki, it is prepared with many different cheeses, normally Greek cheeses. I have no idea how Greek-style cheese behaves, that is prepared outside Greece, but feta will not melt and only weep whey, whereas graviera, kaseri, kefalotyri etc "yellow cheeses" (as we call them) will melt. Saganaki is battered (or sometimes rolled in flour) for this reason- to keep the cheese from spreading after it melts. That's how it's made in Greece. I guess it's made in a different fashion outside of Greece. Finally- although I've never tried to make tuiles from parmesan, there is a large industry of counterfeit Parmiggianio Reggiano: https://www.youtube.com/watch?v=U5U1crD18iM https://www.youtube.com/watch?v=U5U1crD18iM Which might well explain ill-behaved "Parmiggiano Reggiano".

That's cool, although I do somewhat have the same reaction as the poster downthread that I don't really have the experience that cheeses in my dishes separate. Either way, did you figure this out yourself from your chemistry background, or can you recommend a book that is "applied chemistry for dummies with a focus on cooking" without going all "modernist cuisine"? To me, cooking is applied chemistry, but the vast majority of all cook books are "here's a pretty picture, follow these exact steps to recreate".

  I am not the poster you originally responded to and have no formal background in chemistry. That said, On Food And Cooking: The Science And Lore Of The Kitchen by Harold McGee is the prototypical recommendation for food science basics. The following link is a write-up more specific to processed cheese. https://www.seriouseats.com/2016/07/whats-really-in-american-cheese.html https://www.seriouseats.com/2016/07/whats-really-in-american...
