How can bananas be fresh??

Aldi are currently running an ad campaign with a fat guy mistaking a banana for a cordless phone. The strap-line: "So Fresh So Bio".



Apart from a nice example of Swinglish, how can a fruit shipped in containers from halfway round the world ever qualify as fresh??

...picked super green, packed in cold carriers for transport and artificially ripened with methane just before they go to market... like avocados and a bunch of other "fresh fruits"...

Re: How can bananas be fresh??

Nitrogen is used during transport. That keeps them green.

The main point is not too much oxygen. Later just storing them at normal temperature makes them yellow... but yellow isn't fresh.

Nitrogen would probably work better.


The main point is not too much oxygen.
I have seen shipboard nitrogen generators to flood holds in bulk carriers. This is used to provide an inert purge gas when transporting a flammable cargo, which would include anything that produced a flammable gas (such as ethylene).

I suspect that bananas are shipped in containers (there isn't much that isn't nowadays), presumably these are purged and refrigerated during transport with ethylene used to ripen the product at a distribution center close to the final destination.

As I read the bottom of:
http://www.frontlineservices.com.au/..._ethylene.html

it would seem that ethylene is used to trigger the ripening process, which then continues at its own rate.
