You know, sailors used to get scurvy because of C deficiency back a couple centuries ago. Vitamin C degrades really easily, but is there any way you can store it long term other than pills or tablets? I’m just wondering if it would have been possible to do this in the past with the technology that was available.
Citrus.
British sailors got the moniker “limey” because they usually had limes specicially to ward off scurvy.
Yes, but you can’t shelf citrus for like a year. I’m asking about long life preservation methods, not necessarily for sailors back in the day but in general.
Fresh meat contains vitamin C, as most animals can synthesize it themselves. Jerky is uncooked, just dried.
Fermentation can develop vitamin C, depending on what you’re fermenting. Cabbage is probably the most famous example, but pretty much everything you ferment produces at least a little.
Jam, or other preserved and/or dried fruits i would guess were common.
Jams are preserved by canning, which introduces heat, which destroys vitamin C.
Apples was used as well. And they definitely can be stored for a year under the right conditions.
But funnily enough scurvy was also called “the English disease” in some languages.
