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.
Here’s a really interesting article on how it was discovered that citrus would help. They were also able to preserve citrus and citrus juice with alcohol. They could also turn it into a concentrated syrup without too much loss of vitamin C.
From what I just read, they didn’t do this, but dried citrus, when dried at a cool temperature, retains the majority of its vitamin C.
That’s a cool read, thanks for sharing
We then forgot how to cure it: https://www.bluesci.co.uk/posts/forgotten-knowledge#%3A~%3Atext=The+discovery+that+fresh+meat%2Cbacterial+infection+from+tainted+meat.
And had to rediscover it.
Vitamin C is heat sensitive but fermentation is fine and a good reason why fermented cabbage is popular in places with cold winter. See kimchi and sauerkraut, as rice or rye alone would kill you over a long winter. Similar mechanics going on for andean freeze dried potatoes to a lesser extent. Beyond that, it’s straight up foraging for greens and berries but that only really works if you’re moving a small enough group of people to allow forage to be an option. Plenty of leafy greens from forage allowed enough vitamin c to stave off scurvy for many ancient armies and sailors(though not all). Cook notably would beat sailors who wouldn’t eat foraged greens. The other option was uncooked organ meats.
Nice, thank you!

Sauerkraut!
And lots of other fermented products. Possiblities are endless, chances of success are high.
I was also thinking dried fruit/berries, but I’m not sure how well that preserves vitamin C.
Drying can work to a degree if it’s cold, but it really depends on how you dry it since vitamin c is water soluble. Anything heat dried(including sun dried, which over temp and time will oxidize the vitamin C) is out and osmosis like salt drying can bring the vitamin C along with the water into the salt. Modern sauerkraut is often pasturized so that’s pretty useless for vitamin C. Finally canned preserves are canned under high heat. These industrial processes are a major reason why scurvy was so hard to treat at the beginning of the industrial revolution. Nobody could figure it out because they kept heat treating potential solutions. The British pasturized the lime juice at one point, for example.
Thanks, you make good points. I was thinking about basically room dried berries, not in an oven, not in the sun.

Not where I live!
Cabbage.
Sauerkraut is apparently a reasonable way to store vitamin C for a long time. I imagine cabbage in its own doesn’t keep too well.
Cabbage does store better than most greens, but no, not as long as a preserve would.
Jam is the classic way to preserve fruit.
Making jam involves heating the fruit, which destroys the ascorbic acid.
Jams still contain vitamin c, it is just reduced compared to fresh fruit

Gilbert Blane was appointed to the staff of Admiral George Brydges Rodney as Physician to the Fleet in 1779. Blane was a medical reformer who was convinced by Lind’s original experiment with citrus and appreciated the need for a practical way of storing them. After considerable experimentation, he determined that adding 10 percent “spirits of wine” (i.e., distilled ethyl alcohol) to lemon juice would preserve it almost indefinitely, without destroying its beneficial properties.
So like limoncello?
Fermented cabbage, AKA Sauerkraut.
Dried chili peppers are a good source
It’s not ancient but blackcurrant syrup aka ribena was originally developed for this purpose when other fruit supplies were running low in Britain during the war
In fruit.
Fresh fruit spoil easily. How do you preserve fruit for months without destroying the vitamin c, before refrigerators were a thing? Though that really depends on how “longterm” we’re talking here, evidently citrus fruit were, in fact, the solution for sailing boats.
Your body only needs tiny amounts of Vitamin C and you can easily store fruit like apples for more than half a year without refrigeration.
I think the record I’ve seen apples last without refrigeration was two months, three maybe with a fridge. They were shriveled and slimy and gross but still edible. Not sure how well the C preserved, apples aren’t notorious for large quantities of it anyway.
Citrus is a bit less long lasting, either drying out or succumbing to mold.
apples aren’t notorious for large quantities of it anyway.
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.
On a boat, possibly in the tropics, without spoiling? Doubt.

Huh, “sailors” indeed. I can honestly say that I hadn’t noticed this was about boats up until now.
Lemons if stored correctly will last 10 months. My grand father would just toss them in a dark storage room in Greece and they lasted until the next harvest.
What exactly does “stored correctly” mean? I assume dry and cool?
Cool and dark, he would just toss them in baskets in a dark space that didn’t even stay that cool. He might have picked them before they were ripe but I dont remember.
The issue with recreating that environment on a wooden boat is that the sea is really, really wet. Sailing boats definitely had issues with spoiling citrus fruit, it’s part of why the british navy switched to citrus syrup at one point.
Limoncello instead of grog for the sailors
Apparently meat contains enough vitamin c to fend off scurvy if you eat it fresh and not cooked to death (don’t remember just how raw it had to be); it worked for the Inuit. Depending on where your route takes you, that might have been an option. On the other hand, if you can get fresh meat, you can probably also get fresh fruit if you’re not on an arctic expedition.
Yes, that’s an option but it’s not a long life preservation method which is what I’m asking about. It’s just hunting/ gathering fresh food like anywhere else.
Yeah, that’s fair.
Preserved meat like salami has been around for quite a long time. My guess is it’s the same with fruit.
I think life was pretty cheap in that time and place, so very little time, effort, or money was invested in the well being of crew in the lower ranks.
That is to say, while it might have been possible to obtain fresh food, it often just wasnt a priority.
That wasn’t the question, though.
Oh, ok.
I thought we were just kind of chewing the fat, shooting the shit, so to speak.
If you want to be weird about it, your response doesn’t address the question either.
Maybe something that could be dried, soybeans could work. Would have to be properly stored to keep it dry.
I’m kind of surprised no one has said honey. While I can’t find exactly when honey was first used as a preservative, it’s believed that it was first used in ancient Egypt. I also don’t know if vitamin C specifically was ever preserved in honey but honey has been used as a preservative for fruit.
Yeah. Fruit! Lots of fruits have vitamin c.
Almost everything has vitamin C. Except for water, sand and anchovies.
I’m surprised by anchovies lacking it but you appear to be correct, even for raw anchovies. I tried looking at a handful of other raw fish and they also have no vitamin C.
I guess that makes sense, if fish could supply vitamin C I can’t imagine scurvy would’ve been a problem for long.
Stupid jokes with a little bit of factual information are the good type of jokes.
oranges, anything related to citrus family.
