It’s not mold, it’s calcium lactate (2018)

Tangential, but I recently noticed that natamycin, an antifungal agent, is being used in packages of shredded cheese as a preservative.

I was a little taken aback on seeing it, given that antibiotic stewardship has been pushed so much in the last decade.

I realize that natamycin is an antifungal and not an antibiotic, and that mechanisms of developing resistance are likely different between eukaryotes and prokaryotes. However, I’m still somewhat concerned what long-term low-level exposure will mean.

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.

Agreed. I went down this rabbit hole last year, going as far as even buying sodium citrate that's supposed to help it melt together, with mixed results and awful taste.

Never came close to anything resembling a well melted, good tasting sauce.
