Sorry if this is a weird question, but I was just thinking about bananas and how most of the store bananas you buy in places like the US are relatively flavorless but are still sold because they don’t go bad as easily during shipping. So, given this, you’d think you might be able to find the more flavorful varieties of bananas in a preserved form. Like a sealed can… but nope, this doesn’t exist. You can buy pineapples, peaches, oranges, and lots of other fruit in cans, but not bananas.
Why is that? Why are canned bananas not a thing?
because to prevent botulism you gotta bring low acid foods to 240f for at least 20 minutes (more if the foods will absorb lots of heat before they get there).
that kind of processing would make the bananas pretty nasty.
you can make a jam or syrup though, the added sugar brings the acidity up into the no botulism range.
