Spray to stop bananas rotting: New product can keep fruit fresh for two weeks

Spray stops bananas breathing through their skin and kills the bacteria that make them rot

It is derived from shrimp and crab shells

Growers, supermarkets, even consumers could one day buy the experimental spray

A spray that stops bananas from rapidly turning to mush is being developed by scientists.

When used to coat green bananas, it slowed their ripening and so kept them fresh for almost a fortnight.

By contrast, supermarket-bought bananas often go brown and soggy within two or three days.

It is believed that the spray could help save some of the 1.6million bananas thrown away in Britain every day.

Dr Xihong Li, who made the spray from chitosan, a substance derived from shrimp and crab shells, said: ‘We found that by spraying green bananas with a chitosan aerogel, we can keep bananas fresh for up to 12 days.

‘Once bananas begin to mature, they quickly become yellow and soft, and then they rot.

‘We have developed ways to keep bananas green for a longer time and inhibit the rapid ripening that occurs.

‘Such a coating could be used at home by consumers, in supermarkets or during shipment of bananas.’

Ok, this really bothers me. If this spray is used, bananas would no longer be suitable for vegetarians and vegans, not to mention people with shellfish allergies. Pretty disgusting. I would never knowingly buy fruit tainted this way. Please, just leave fruit and vegatables alone already! Our food is tainted enough.

2 or 3 days? They look fine and not too yellow at the store and by the time I’m washing them (I wash everything) they are already looking bruised. What’s up with that?

Yeah, because food in the 1850s was so much safer and better, if you don't count the ergot fungus outbreaks, milk fever, bad meat, and high number of food poisoning deaths, and little stuff like that.

Food fetishists are a half bubble out of plumb.

If customers want a product, the market will provide it.

Don't interfere.

Food fetishists have NO sense of humor. They obsess over everthing they eat. They are a pain in the arse.

They are also generally pretty clueless about the real history of food.

I should have compassion, but I just tend to point and laugh.

Don't interfere.

That's the hardest thing for nanny staters (including food fetishists) to do. In fact, they don't.

There should be a law, and men with guns to enforce it.... ;)

I noticed this with bananas recently. Appear to be just turning yellow from green, by a day or two, peal them and they are bruised in inner core already rotting. Sliced them and ate for 2 days, 2nd day I felt sick from them. No more of those for me.

Try the gentle fabric cycle. Much gentler wash action.

I think it was Michael Savage who pointed out that morality has shifted from sex to food. A housewife in the 1950s, unless Kosher and Jewish, didn’t care where her food came from or its ingredients, but was careful on staying chaste until marriage and faithful while married. Food was free for all while sex was constrained. Now we worry about whether it is locally grown, organic, have fights over vegetarian and vegan as holier than thou, but sex is a free for all.
We moved our morality from the bedroom to the kitchen.

I rinse chickens that I kill here on the property with Clorox solution. My body can handle the chloride (which goes away over time), but it can't handle salmonella.

Why should fruit be tainted with fish parts?
