Activated Charcoal Sacs

Small sac of activated charcoal prevents food from premature ripening

This is a little sac like the ones that contain silica gel desiccant, but it contains a little bit of activated charcoal to adsorb the ethylene gas that fruit produces as it ripens.

Supermarkets stick these in high-priced fruits that are often sold in sealed containers (e.g., berries) to increase shelf-life. After you take the package home, you eat the fruit and throw out the packet.

Mentions activated charcoal and potassium permanganate as ethylene removers. [spidermother, Apr 19 2012]

       It would be slightly cooler for your fruit bowl to have a flare stack, like oil rigs do, to burn off the unwanted ethylene.

       The gas that bananas give off is ethyl ethanoate, from memory. Going back to the late 1970s for possibly dodgy memory... I'll check.
UnaBubba, Apr 17 2012
  

       Nope, 3-methylbutyl acetate. Sorry.   

       Ethyl ethanoate has applications as a solvent for decaffeinating tea and coffee. Didn't know that.

       [UnaBubba] You're thinking of the ester that (largely) gives bananas their smell. They _also_ give off ethylene.
spidermother, Apr 17 2012
  

       Yep. It was 1979 when we looked at esters in chemistry and I've not really had any need to use the information again. Please excuse my faulty memory.

       hmmm... just thinkin' 'bout that ethylene gas... couldn't you bubble it through some chlorinated water to produce ethylene oxide? That seems sufficiently useful, toxic, and explosive that it ought to be a standard part of a halfbaker's armamentarium.

       Exploding bananas?

       This is a slick idea and easily testable for a science fair project, ideally using time lapse photography. Two cake dishes with bananas, one with several packets of charcoal and one without. Do they ripen at different speeds?
