carbon monoxide detectors gas leaks image
Jacki
So I'm wondering if there are any gases that can cause bananas to ripen quickly. I'm not interested in the gases they produce and etc. The reason I'm asking is because when I brought my bananas home from the store last night within hours they had large brown spots that were not there when I picked them out. On top of that the cats were acting a little funny so I'm wondering if it's a sign of a gas leak in the house. I'm a little concerned because our carbon monoxide detector is broken.
Answer
Ethylene will cause rapid ripening in bananas. That causes the bananas to release more ethylene. Once they start ripening it can happen quickly. They also may have recently been treated. Other gases aren't going to cause that ripening. Ethylene is a hormone that causes ripening. You aren't likely to get that gas in the house. It is possible since it is a trace contaminant of natural gas and can also be produce by the combustion of wood. If you had a gas leak or poor ventilation from a fire place you might get enough to speed the ripening of the bananas. They naturally accelerate their ripening so there is no reason to assume that just from the bananas. It is still possible though.
"Bananas use ethylene to stimulate fruit ripening. A bunch of bananas will stay green for a long time until the ethylene concentration in the air around them becomes high enough. When that happens, then they begin ripening and they begin releasing more ethylene, which makes them ripen faster and release more ethylene, etc. In this way, all of the bananas will ripen very suddenly and simultaneously. Keeping bananas in a plastic bag will make them ripen much more quickly than if you leave them out in the open, because the plastic bag traps the ethylene and thus makes its concentration rise more quickly."

what could this weird gas smell from my gas stove?

the gas company came out and they guy had his detector or whatever. He said that it might be carbon monoxide and it might be incomplete combustion from one of the pilot lights and that they may need adjustment and that it wasn't a natural gas leak. I only smell it when I stand in front of the gas stove. He also recommended I open a door or window when I have the stove or oven on. He also pointed out the debris flakes under the stove cover as fuel debris or whatever. I put a carbon monoxide detector in the kitchen for about an hour and it didn't go off. What should I do? Call an appliance repair company? will it be expensive? Thanks!

I doubt that it would take a repair person very long, a service call, probably in the $45-$75 area depending on your location, plus time and materials, say another 1/2 hour. I'm guessing $100 total. You might well try this yourself. Go to a store that sells welders and welding supplies and ask for a "welding tip cleaner". It will be in the $5-7 range and is a small aluminum case with a series of round wires in various diameters, which are actually files. They are used to clean gas welding tips which have various sizes of orifices. Shut off the gas valve behind the stove, and use the tip cleaner to clean the pilot light orifices. The small files are flexible and will bend and you can increase to larger sizes until you feel metal to metal contact. Then, turn the gas back on and relight your pilots. If there is no improvement, you aren't out much, and the tip cleaner can come in handy. They are great for cleaning the windshield washer nozzles on your car. Good luck.
