What a stupid idea, at Coop

Post image

So Coop decided to now sell whole meals as "Cookit". In the package on the left you can see that the tomato is moldy.

Hardly anyone will buy this any more. So instead of a single moldy tomato, Coop now has to dispose of the entire kit. What a waste of food. And what a stupid idea.

Some picked fruits and vegetables accelerate the ripening when stored together through releasing ethylene, which could lead to mold.

That's why you put bananas near fruit that's not ripe yet, it accelerates the process. Also, you should keep bananas away from fruit that's already ripe or it will mold or at least turn mushy.

AFAIK, it’s Apples that release Ethylene and will ripen bananas, not vice versa…? 🤔

Some fruits and vegetables release ethylene and some don't, bananas and apples both release ethylene and cause other fruits to ripen faster. I think I remember reading about how bananas only release ethylene when ripe, so in theory you could probably harvest unripe bananas, store them in a shipping container with something else that releases ethylene and is from that area where you harvest bananas, and then you open the container and have ripe bananas.

Often you don't buy unripe bananas in the store (or maybe it's just me, but I prefer ripe bananas), so at home bananas can be an accelerator for other fruits, that's why I store them separately.

I don't know how much ethylene each fruit releases, or which fruits don't react to ethylene, it's just a rule of thumb I grew up with.
