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!

People are super religious about this but I've never been able to tell pre-shredded cheese from cheese I've shredded myself and I don't think anyone else can tell the difference in a blind taste test.

Are you buying cheese that's shredded at the deli or something? The processed stuff in the bag seems to be plainly noticeable to me...

Sure, when you're eating it by the handful, but when it's melted in a dish (the thing people typically use it for) you aren't going to notice.

There are plenty of dishes that include unmelted shredded cheese. Salads and tacos are extremely common uses of shredded cheese here in the US.

Sure, and I also doubt people's ability to tell the difference in a blind taste comparison. People claiming to do so visually see the anti-caking agent, they don't taste it. It doesn't taste grainy. You can taste a bit of corn starch or cellulose directly and tell that it doesn't taste 'grainy' or even have much of a flavor at all.

The point of the anti-caking agent is to prevent the cheese from sticking to itself, which inherently affects the texture of the cheese in your mouth... it doesn't stick to itself the same way freshly shredded cheese does, particularly if the cheese is soft and sticky like processed american cheeses. Although it is likely less noticeable for dryer and harder cheeses.

It does so by keeping the cheese 'dryer' than it normally would be. Putting it in your mouth basically undoes that. You're only going to notice if you're eating it by the handful, not when you're using it in actual food dishes.
