Can acidic and carbonated drinks corrode aluminium bottles?

Submitted ⁨⁨1⁩ ⁨year⁩ ago⁩ by ⁨thonofpy@lemmy.world⁩ to ⁨[deleted]⁩

I like to put lemon or vitamins (those tablets that also create fizzyness) in my water and have been wondering if it is problematic to do so in my aluminium drinking bottle. I wouldn’t normally think so, since soft drinks also often come in aluminium cans, but I’m not sure. Are aluminium salts even unhealthy?

Your aluminum drinking bottle will have a plastic lining to protect it from leeching into things, so it shouldn’t really matter.

Certain types of beverages can definitely cause some types of cans to erode, yes. You’d have to know whether or not your aluminum bottle has an interior lining or not. There are also different types of linings.

Unfortunately, I only know these things from a friend who works in the canning industry so I can’t speak to them with any degree of detail. But some manufacturers get their beverages tested and then have to can them in certain types of cans for that reason.

  I have a Quechua bottle that looks slightly yellowish/golden on the inside. Might that be some sort of lining?

    that’s probably just anodized aluminum (not lining)

    The yellowish color isn’t lining, lining is only in aluminum cans because it’s cheaper and easier than using thicker aluminum and is usually clear (unless stained). The lining is what gives the cans structure, usually made of epoxy and/or bpa plastic. Without the lining, you can tear a soda can like double thick tin foil. No need for lining in a steel bottle.
    
    The yellow/golden color on the inside of your bottle is just the metal being stained. Stainless steel isn’t really stainless, just harder to stain because the chromium in it forms its own layer of oxidation that protects from being directly touched. Best guess is that the lemon you put in your water breaks down that oxidation layer before you can drink enough, then the lemon and vitamins/minerals/coloring in the tablets stain the metal

If it’s a water vessel I’d only put water in it. Aluminum cans are lined with a specially designed polymer liner for the particular food or drink in the can. Your water bottle is likely not. Don’t put anything but water in it.

there’s a reason beer was the first canned beverage. more acidic things like some sodas corroded aluminum too much until plastic liners were introduced

these fizzy tablets should be ok, but lemon is probably a nope

  that said, i wouldn’t care either way too much. if you drink black tea you probably ingest more aluminum this way

There are health risks connected to aluminum bottles and acidic drinks. Aluminium is reactive to acidic drinks.

I’m no expert but my understanding is all drinking cans are lined with plastic to withstand erosion.

Aluminum soda cans have plastic linings, because the acids can dissolve the aluminum. What that means for your drinking bottle, I don’t know.
