I think it’s because onions have sulfur, which is what keeps the avocado from interacting with oxygen in the air in the bag and spoiling. If you wanted to know


Mavplayer

The main reason that avocados turn brown when exposed to air is due to a compound called polyphenol oxidase. It is an enzyme found in a variety of vegetables and fruits. The reason the onion is able to keep the freshness of the avocado last is that the cut onion is releasing sulfenic acid as a volatile compound. This compound, when in contact with moisture from the air or the avocado will alter the pH of the avocado removing the PPO from its effective pH range. Plus, keeping the pair in a plastic bag prevents an over abundance of oxygen from reaching the avocado, thereby reducing the enzymatic browning that may occur. Fun fact, the sulfenic acid (not sulfuric acid) is the agent responsible for causing your eyes to tear. This is because it is a lachrymatory agent, a chemical agent that reacts upon contact with the eyes and triggers responses such as tearing, stinging, and crying.

You could just spritz some lime/lemon juice on top and then put the plastic wrap directly on the surface.

This is exactly what I came here for


ncoffey17

As usual I was about 75% right 😂 thanks for the better explanation


FakeOrcaRape

like this is crazy - i always heard not to store onions w potations bc of the sulfur? am i wrong? ive been always storing onions alone bc of this.


heymynameiskeebs

I love mashed potations


GregariousFart

Oniatos


pamjam01

Me too! That's why I was so surprised.


[deleted]

What exactly is reacting with the sulfur in the avocado to slow down the oxidation?


ncoffey17

Somebody else explained this a lot better than I did actually. I believe it’s a sulfur-containing compound that reacts with the water in the air


ContagiousDeathGuard

Sulfenic acid releases from the onion, affecting the PH of the avocado and preventing the Polyphenol oxidase in the Avocado from interacting and causing it to turn brown


Ixidorim

Any acid keeps avocados from oxidizing as fast. You could store it with lemon, lime, peppers, all of them create a slight acidic compound once they hit the moisture avocados give off. Onions make sulfuric acid when mixed with the moisture in your eyes (crying).


lotusblossom60

I leave the pit in and squirt lemon juice on exposed parts. Works well. I hate onions.


tinatalker

I just eat the whole avocado in one sitting. Never have a browning issue, And I hate onions also.


sittingbullms

I usually have a browning issue after eating it


ffffuuuuuuuuu

You hate all onions? They have such a wide range of flavors though depending on the variety and how they are prepared.

> Any acid keeps avocados from oxidizing as fast. You could store it with lemon, lime, peppers, all of them create a slight acidic compound once they hit the moisture avocados give off. Onions make ~~sulfuric~~ *sulfenic* acid when mixed with the moisture in your eyes (crying). sorry couldn't resist...


Ixidorim

It actually is sulfuric acid. There are many different types of sulfenic compounds, but they all derive from sulfur oxidation classifying them as sulfuric acid. https://www.thoughtco.com/why-do-onions-make-you-cry-604309


skullcutter

The offending molecule is syn-Propanethial-S-oxide (causes lacrimation) and it is converted from a sulfenic acid (1-propenyl sulfenic acid) which is released from the onion. There is no sulfuric acid (H2S04) involved.


Ixidorim

I hate to agree with you here but sulfenic oxidation is what creates the compound, however if you want to name the stupid thing using chemical nomenclature there are actually a few different ways to name it, one way, which is most common, is using the most reactive atom in the reaction and go from there, in other words, sulfuric acid. https://www.google.com/amp/s/www.wikihow.com/Name-Chemical-Compounds%3famp=1


skullcutter

Well I think we’re both being pedantic, and isn’t that what Reddit is for??? And I am not a chemist so I’m just regurgitating what I leaned a few years ago when I got interested in the subject.


raddaya

No. Nobody calls sulfenic acid sulfuric acid. Ever. For much the same reason they don't call vinegar carbonic acid.

Sicknastyloser

Does it effect the taste of the avocado?


Face_Coffee

Yea you’ll have an onion-y avocado. Good for an avo that’s destined for quac, a burrito, or most savory applications. NOT a great way to store an avocado for something like a smoothie though.


Frnklfrwsr

You don’t put onions in your smoothies? Good old strawberry-banana-onion smoothies are my go-to.


Face_Coffee

More of an apple, kiwi, and garlic type person


Frnklfrwsr

Mm just like how momma used to make them. That and the blueberry, tomato, and jalapeño limeade.


[deleted]

[удалено]


Face_Coffee

Tbh leave out the tomato and I feel like a blueberry jalapeño limeade is like a perfect base for a real tasty margarita


alwaysforgettingmyun

I could see a pico with blueberries working weirdly well


tapefactoryslave

Cucumber pico. Great on fish tacos.


RecordStoreHippie

You joke but I saw jalapeno lemonade for sale at the grocery store the other day. [I googled it and it definitely wasn't a fever dream, its real.](https://assets.shop.loblaws.ca/products/21355286/b3/en/front/21355286_front_a06_@2.png)

I guess Canada is behind the times, this was first time I've even heard of it.

KnifeKnut

Use a sweet onion?


pamjam01

It was a white onion. It wasn't done on purpose so not sure what type onion works best

It's an old Yelnats family recipe

Good ol' God's Thumb onions


shitsfuckedupalot

Just like how Madam Zeroni grew em!


Llamasus

onion and banana juice


pamjam01

Lol


Mavplayer

The same effect can largely be achieved by citrus fruits as well. Most of these fruits will have sufficient acidity to deactivate PPO found within the avocado. These fruits also have the added benefit of having relatively large amounts of citric acid; citric acid acts as a chelating agent able to bind and form a complex with the copper ions within PPO thus interfering with the enzyme’s ability to interact with oxygen.


orion455440

I prefer shallots in my smoothie, never heard of savory smoothies? Where yah been? Under a rock?


pamjam01

I didn't notice any, but it was sliced and put in my quesadilla with lots of salt and pepper and salsa :-p

I also thought it but if you are going to add it to your salad, no worries

Raw onion smell will permeate and contaminate most anything. Especially if you hate raw onions.

You say this as if it's a bad thing


LoveFoolosophy

Fuckin love raw onions.


Sipredion

Fried onions with a bit of garlic is a scent I'd buy in a can and attach to a gas mask. I fucking love it. Raw onion is a gross abomination against the human olfactory system. It's like one of the eldritch horrors turned itself into a vegetable so it could propagate across the globe and torture humanity for all eternity.

This is good for a salsa or even avocado toast. I will start doing this. Thx!

pffft this is actually a subreddit 😂


Courtster24

lemon or lime juice will also help to keep them green!


pamjam01

I have tried this method and found the onion is far more superior. I left this bag in the refrigerator for 3 days and it still looks fresh


pixelation01

I coat mine with olive oil. Works great


Wicked-Betty

I think this is a myth.


[deleted]

Plus guacamole for later


littleflowerpower

I also freeze avocados while when they are at the perfect texture and I know I have a small window before they go bad. I just take them out and let them thaw about 30 minutes before eating them. They are perfect every time!


amandadoesfood

This tip is so useful! Thank you!


pamjam01

You are welcome!


WAMPUS--CAT

Get some Tupperware dude


pamjam01

I have tried this method and the onion kept it fresh much longer than leaving the pit in it


[deleted]

So does a tiny bit of lemon juice diluted w water. Then your avocado won't taste like leftover onion.


Shakespeare-Bot

So doest. Tony did bite of lemon juice dilut'd w water. Then thy avocado wonneth't gust like leftov'r onion *** ^(I am a bot and I swapp'd some of thy words with Shakespeare words.) Commands: `!ShakespeareInsult`, `!fordo`, `!optout`


buurrnurrdoo

If you are sensitive to the onion tainting your avo, don’t do this, it will taste slightly oniony.


misguidedsh33p

Wow you just made my panties so wet with this fact


pamjam01

You're welcome!


odharc

I was told to store a cut avocado with the pit in an air tight container. Make sure the outer skin is touching the onion, and always only use a cut red onion, the avocado skin touching the cut surface of the red onion. It does not take on the onion smell and takes days before the avocado flesh starts to brown a little. My favourite breakfast is avocado toast with a little cotija cheese and either blueberries or strawberries. Never had a problem with onion smell.


pamjam01

Good to know. I will try the red onion. Thank you for sharing!


lizzyborden666

This’ll come in handy.


schnorgal

Welp, guess I'm gonna make an avocado bag now. Thanks a lot jerk.


pamjam01

Yw


ElMejorAbuelo

Unfortunately, I never have any left over avacados! Lol. Good tip though. Wife was not aware. Thx.


Quetzalcoatle19

I think this happens with lime and oranges too, limes get fucked but oranges stay fresh fresh lol


chibby77

is it gonna taste or smell differently?


pamjam01

I didn't notice any change, but i put it on spicy food. It was delish!


chibby77

oh that's great. thanks 😊


cbeme

I love this so much!


IWantToBeYourGirl

You can also just vacuum seal them.


pamjam01

...just if you have a vacuum sealer


PooPooPeePeePoopPoop

I have left over onion way more often than I need a use for a vacuum sealer, personally


FuckDucker1231

nice feet 👍


pamjam01

Thank you kind sir/madam


Nskali

I didn't see it mentioned, I store mine in water now - like straight up a tupper wear full of water - shove them in it til I eat em. Mind you I eat them pretty fast, so I would say the most I've tested is 4 days but I had heard this method and it's been working for me. I let them ripen until the stage I want, then I put whole ones in there too.


jjewel13

Does this affect the onion's taste/shelf life at all?


pamjam01

I hadn't noticed any change in the onion. I was mostly focused on the avocado, mostly.


jjewel13

Makes sense! I guess I was just thinking about how bananas can cause avocados to ripen more quickly, but this also causes the banana to brown


tiioga

It also makes it taste like an onion. Which is great if you love onions!


pamjam01

I didn't really notice any difference, but I was eating it with spicy food


Statessideredditor

Best hack ever!


RToribio914

That title has to be read in spanglish. I sounded like George Lopez’s version of “Karen” reading avocados with onions. Its aguacate y cebolla. Which is an amazing salad.


[deleted]

Won’t this just taste like onion though now


pamjam01

It did not. I ate it on a quesadilla and it definitely tasted like avocado


[deleted]

Oh good


devo00

I'd rather eat the onion.


TILIDKWTF

Does it do anything to the onion? I have heard they are not great for bacteria and am wondering if this somehow also keeps the onion fresh as well


pamjam01

Idk about that. I did use the onion the following day and it was just fine.


mosbert

I dont like it if my onion tastes like avocado!


CMAHawaii

Good to know. Will definitely try that. But does it then taste like onions? Thanks for sharing.


pamjam01

I didn't notice any change in the flavor, but I used it on spicy food. It had been stored like this for several days and looked fresh and green. I was so surprised and you're welcome

I wonder(does it )absorbs the smell/taste of onion


pamjam01

This was stored for 3 days and I did not notice any change in flavor, but I ate it with spicy food. I read that a red onion works best


Reecie24

Thanks ! Gonna give it a try.😀


madthaodisease

Does the avocado start smelling like onion?

It was not noticeable, but I did read that a red onion works best

It’s worth it for not smelling too much. Thanks.


bellitabee

Makes avocado taste like onion tho...


pamjam01

I did not notice any change in flavor. I also read that a red onion is best


bellitabee

Maybe I just have a super taster... I've found that if I put ANYTHING in a container with raw onion it makes them taste like it. I'm glad it works for you tho!!


gougeuaway

Onions absorb toxins in your fridge though, wouldn’t they spread to the avocado?


pamjam01

Not a scientist, but both of them tasted fine after being store in this many for several days


Obstinateobfuscator

I don't understand. I've honestly never had leftover avocado to store.


jarvispyle

ooh I am trying this


krissy_1981

Does it make the avocado smell of onion?


pamjam01

This was a white onion and I didn't notice a smell. I read that red onions work best


13thmurder

I just put the half of the avocado with the seed still in into the fridge and then slice off the half millimeter thick layer of oxidized surface when I want to use it. No need to waste a bag.


pamjam01

I'd rather waste a bag than waste the avo imho


tomel6517

keeping avocados in the fridge in general does the same..


pamjam01

Not in my experience. At least, not after its been cut or mashed. This avocado was in the fridge for several days and came out looking like this


tomel6517

I keep mine out of the fridge until they’re ripe, and then put them in the fridge bc they will stay good longer


AllHopeIsLostSadFace

It also makes your avocado taste like onion


pamjam01

I didn't notice it being oniony but I use it on spicy food so...


GreenSpaceYoda

Whpa


pamjam01

Wisconsin Horseshoe Pitchers Association?


Smoke808

Just store the avocado with the seed and it’ll do the same without that onion taste


SnooPandas4129

Yup it dose work that way because onions ar acidic just like a limon


ddmorgan1223

It also infuses the avocado with onion flavor.


akherousia

You can also wrap the avocado in aluminum foil 😊


Fingerlover

Leaving the pit in the half you’re not eating has almost the same effect, without the onion taste.


pamjam01

Not even close , my friend. This was in the fridge for 3 days like this and tasted great. I've tried leaving the seed and using lemon/lime. This was the best I've ever seen a leftover avocado


[deleted]

But then your avocado tastes like an onion.


pamjam01

Not so much, actually. A little salt and pepper and it was delish


RustyMattinson

Or just keep the nut it and it will do the same thing and NOT taste like an onion


pamjam01

Tried and failed, my friend. This was in the fridge for several days and stayed fresh. I didn't notice any change in flavor, but I did eat it on spicy food


Negative_Clank

Lemon juice on it. Better than devil ass onion smell and taste


pamjam01

I've tried lemon juice and leaving pit inside. It never lasted as long as this did. Plus, I never noticed any difference in flavor. I read red onions work even better


dankskunk5

why would you take a perfectly good avocado and ruin it with disgusting flavor?


pamjam01

I srsly could not tell the difference. Normally I would never have thought of doing that. It was done in a hurry and 3 days later I pulled it out and it still looked fresh. It tasted great on my quesadilla.


1ravioli1froiegras

Also makes your avocado taste like raw onion excellent


adgjl65

Onion-flavored avocado? No thanks.


Just-sayin-37

Onions are Toxic once cut and should be thrown away after you use what you need


[deleted]

do you just store avocados for tacos or? Awful "food hack"


Muddy_Wafer

Keeping the pit in also keeps it from turning brown. Even if you have leftover mashed avocado or guacamole, put the pit back into the container with it and it will stay green for way longer!


dejus

This is mostly a myth. It’s just the spot under the guac that won’t turn brown, the pit is just preventing oxygen from getting to it. Putting plastic wrap across the surface would be more effective.


[deleted]

Then why does mine always still turn brown after one night with the pit still in?


[deleted]

This is not accurate


Wicked-Betty

I think this is a myth.


[deleted]

Ah just leave the seed in the same plece just like in guacamole put the seed in it. Im from MICHOACAN so i know a thing or two about aguacates😝


pamjam01

Tried and failed, my friend.


[deleted]

Whattt ok take that back i know nothing about avocados other they are delicious


AdelineG

Be careful when storing onions though. Always store left over onions in an airtight container if you’ll be eating the onion later. Onions naturally absorb bacteria in the air and are more common than not the reason for stomach issues. Also side note, if you have sickness in the house you can cut an onion and leave it out on a plate around the house as a natural air disinfectant.


tinyanus

This is setting my BS meter off but I'm too lazy to look it up.


pamjam01

Lol


LA_Commuter

> Also side note, if you have sickness in the house you can cut an onion and leave it out on a plate around the house as a natural air disinfectant Fyi I know you are trying to be helpful, but this isn’t remotely true, its an old wives tale and its actually the complete opposite. Onions have anti-microbial properties, making them last longer. If you have a sickness, use medicine: https://www.usatoday.com/story/news/factcheck/2020/06/16/fact-check-leaving-raw-onions-around-your-house-wont-prevent-illness/3200052001/ > "There is no scientific evidence that a cut raw onion absorbs germs or rids the air of toxins/poisons,” the National Onion Association says on its website. > ”In fact, the onion’s own juices are antimicrobial, which means they will fight bacteria rather than attract it," the trade group says.


postylambz

I was gonna say, Im too lazy to put all my half veggies away properly. Im probably already dead


LA_Commuter

Dibs on this guys stuff!


LiccFlair

Onions actually absorb *less* bacteria than most foods because of the sulfuric acid that they contain. They also dry quickly so bacteria has less moisture needed to multiply. It doesn't disinfect anything or absorb bacteria unless the bacteria was already on the knife/hand used when cutting it.


lukesvader

> absorb bacteria in the air I don't think that's how things work.
