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.
Yeah, I’ll concede that.
But again, long storage is not just feasible but relatively trivial - a cool basement, harvest before ripe, many months of apples to be had. Maybe it depends on the cultivar? Either way, for most of human existence in seasonally cold climates, storage simply was the only way for having access to fruit during winter and early spring.
Preserving has been an option for much of our history and it works much better than just storage.
Edit: to be fair, both storing and preserving basically just mean keeping. I’m talking more specifically about dehydrating, pickling, fermenting, and candying.
