So we've all heard apples give off ethylene

so do a lot of other fruits- bananas, mangoes, melons, kiwis, the peach/plum/apricot group, etc

Ethylene is a gas that's also a plant hormone- it tells plant cells that it's time to die.
From the plant's POV, ripening is just a controlled, florid, drawn-out Shakespearean death. When fruit gets hit with ethylene, it goes through its death cycle faster- aka faster ripening.
But vegetables that *aren't* ripe fruits- like leafy greens, herbs, cukes, green beans, mushrooms, summer squash, etc- don't need to ripen to be edible.

When ethylene touches them, they just straight-up die and start to rot ASAP.
Funny coincidence, our meal kits always got there with two things off:

-meat was often just-barely cool 🙄

-ethylene-sensitive vegetables were usually TRASHED and unusable.
It's almost like someone stuffed those veggies in a barely-refrigerated box and packed it with ethylene-generating produce, sparking a rapid cellular death and spoilage cascade?
Putting a mishmash of veggies in a box and toting them around town for deliveries is a phenomenally bad idea.

It will destroy your produce. Even putting them in the same truck can do that, depending on the situation.

EVERYONE IN THE PRODUCE INDUSTRY KNOWS THIS
And that's why ~mainstream grocers~ don't really do delivery. They know they're doing.

The startups *are* doing it. And I just. How you supposed to trust a "food co" that doesn't even know you can't put melons & lettuce in the same box? These dudes are gonna solve food waste?
anyway @zalambar call me crazy but I'm pretty sure grocery delivery startups in fact *don't* want to hear this, since it means their entire business model is grievously flawed lol
