Why does a brown paper bag speed ripening?

  • I often see this technique suggested as a way to speed ripening. Why does it?

    Also, is there any data available on how fast it ripens comparatively?

    The ripening itself is caused by ethylene gas released by the food, which is trapped by any kind of bag.

    As far as I know, there's nothing inherently special about a brown paper bag, other than the fact that it's porous and thus still allows some air to get in and out. Plastic ziplock bags have no ventilation, so they don't work nearly as well.
