Well that is bizarre, I couldn’t even find it when I typed it into the websites search feature. But if I type ways to keep your fruits and vegetables fresh longer into google search it pops right up as the first thing?! 
Anyway the suggestions that they gave were:
(1) Give your berries a hot bath, by immersing and swishing the berries in their plastic basket in a pot of hot water. Roughly 125 degrees for 30 seconds. Then spreading them out on a towel to allow them to breathe while stored. The article says that this works best for strawberries, blueberries and raspberries. (This stops the onset of mold)
(2) Store tomatoes outside of the refrigerator in a bowl lined with a paper towel and the stems facing upward. Keep them away from heat sources and direct sunlight, also move them around in the bowl periodically to keep them from bruising. This should allow them to keep for at least a week. .
(3) Wrap your unwashed leafy greens in paper towels and then place them back into the bag to soak up excess moisture. (which you have already mentioned
)
(4) Refresh lettuce and herbs with an ice bath if they are looking a bit wilted. Just shake them around a bit in the ice water, a minute or two should do.
(5) Freeze extra fruits and vegetables if you have purchased too much. Just make sure that you blanch them in hot water first to neutralize any bacteria that might be present. They recommend freezing items such as bell peppers, green beans, broccoli, brussel sprouts, cabbage, celery, cucumbers, onions, eggplant, mushrooms, strawberries, blueberries or bananas.
(6) Refrigerate ripened bananas. Yes the skin will turn black within a couple of hours from the cool temperatures, but the fruit within doesn’t continue to ripen as quickly.
* The cold temperature of a fridge encourages an enzyme found in bananas (polyphenyl oxidase) to polymerise phenols in the banana skin into polyphenols, which in turn blackens the banana skins. News to me

This is all my paraphrasing of course, but to avoid any unintentional theft of intellectual property or copyright laws (lol) It is from an article by Inhabit and the author is unnamed. 
Sorry guys, next time I will check that the link is working properly before posting!
