Will Food GO BAD in a Vacuum Chamber?

A lot of food goes stale or rotten when it's exposedto air or moisture.

What happens if they stay in a vacuum chamberwhere it doesn't have either one?[Captions by Y Translator]YouTube user Grant Feltz asked if food would get stalein a vacuum chamber?Grant that is a great questionand we would love to try that out.

So today, we've got a variety of foods that go badwhen they're left out.

We've got some jars that we're going to try and turn into small vacuum chamberswith the food in them and see what happensto that food after a couple of weeks.

Here's what we're going to try.

We'll modify these jars sothey can hold a vacuum with the food inside.

We'll have some food in the vacuumed jars as wellas keeping some food out of the jars as a control.

After two weeks, we'll see what's happened.

We've got five different foods that were going to test,so let's take a look at them.

First we have a couple of apples.

We'll cut these into slices.

One bunch of apple slices will go into a jar with all the air sucked out,and the other batch of apple slices will still go in a jarbut we'll leave the lid off.

Hopefully we can keep too many fruit flies from finding it.

We may end up putting a thin cloth barrierjust to keep them out.

We've got some milk with an expiration dateof less than two weeks from now,and we're going to put some of it in the jar in a vacuum,and some of it just leaving in the bottle,and let it sit for two weeks and see what happens.

Graham crackers are something that I think get very noticeably stale pretty quickly.

If they're fresh, they break fairly easily,they're pretty crumbly and they have a nice dry crunch to them.

Normally if you leave them out, they get really soft, almost mushy.

You can't even really snap them.

They almost bend.

So we're going to try some graham crackers in a jar.

And some graham crackers just sitting on a plate.

Potato chips, famous for coming in bags full of air will also go staleif you leave them out.

Now a lot of potato chip bags actually come full of nitrogenrather than normal air.

And that's because the nitrogen doesn't react as muchwith the chips inside,and we're going to give a comparison between storing chipswith nothing, not even nitrogen, and just leaving the bag open.

These aren't stale yet.

Delicious!Lay's that will be 1 million dollars.

Lays?Lays? Dang it.

And finally we have some white bread.

Bread if you leave it out, it usually just gets really really dryat least in this climate.

We're going to see if the same thing happensin a vacuum chamber.

We've got all our food laid out.

So it's time to start making our vacuum jars.

And we've done something similar to this before.

We took some glass soda bottles, drilled a small hole in the capand had a piece of rubber that sat over that hole.

We put the whole thing inside our larger vacuum chamber.

And the air is able to be get sucked out of the jar when we put pressure back in,that rubber seal gets pressed up against the hole,keeping it nice and closed.

So that's what we're going to try doing.

We've got some of these larger jars so we can fit a good amount of food in it.

Let's see how it works.

Now we're using some electrical tape to hold this rubber in place.

We're not trying to hold it down.

We just want it to not go anywhere.

So I'm not stretching the tape tight.

I'm not pressing it down over the whole thing.

We still want air to be able to escape outpast this rubber and then have it kind of sucked down onones there's low pressure in the jar.

Let's give this a test.

Beautiful.

We let the air back into the main jar,but the rubber stopper prevented it from filling the little jar.

Now I think if we peel this stopper away, we'll hear the airand watch the marshmallows collapse a little.

Or a lot.

Yeah.

Yeah I'd say that's working pretty well.

Wonderful.

All right we can fit whole graham crackers into this jar.

So I'm just going to throw a couple in there.

Whole slice of bread does not fit in but I'll just cut it in half.

And I think what'll be the best test isI'm just going to put half of it into the jarand leave half of it in the other bottle.

That way there is some air in the bottle.

A good side by side.

Don't expect graham crackers are going to do a whole lot in a vacuum.

That already has moisture in it.

The sides of that have started fogging up and I'm pretty sure that is moistureleaving the bread.

Look at all that moisture cleared up too.

Ooh.

It is boiling.

The juice seems to be getting pulled right out of our apples.

It's kind of hard to keep them in zero pressureand keep all the juice in place.

So, the results on the apples may be a little strange.

I think in the spirit of making everything as equal as possible,trying to eliminate variables we'll just store the non vacuumed versions in jars,but with the lids off.

Why it was pressurized?Why are they all pressurized?With the apples, I am going to put a pieceof paper towel over the top.

Maybe even tried poking some holes in it.

I want there to be good air exchange, but I also don't want to fill the housewith fruit flies.

Now we're going to set these aside for two weeksand see what has changed.

The milk will be in the fridge.

Both of them.

Everything else will just be sitting out.

Time has now passed and in fact more timethan we originally planned.

We were going to go for two weeks.

And then we just got busy with our schedulefilming other videos.

So it's actually been four weeks that we've let these things sit out.

Which is plenty of time for stuff to go bad.

Let's see how things are.

We're going to start by just popping all of the sealsand we'll see it's possible that we haven't kept a perfect vacuumon all of these.

But we'll see how much air seems to rush inas we break the seals on them.

Side-by-side test.

Graham cracker sitting open in a jar for about a month.

It does have a little bit of snap left to it.

Not much.

And it definitely tastes like an old graham crackerthat's quite stale.

Don't really think of graham crackers is something that started tasting badbut that was really not pleasant.

Much more crumbly as it snaps.

Much crisper.

And a lot more crunchy.

You can actually hear that when I squish itand makes like crunching sounds and this one just kind of mushes.

This one snaps apart in the crumbs.

So graham crackers worked really well.

Now the bread I already know I'm not going to do taste testsbecause there's mold on both of them.

However, the mold on the open one, very minor.

There's just a little bit growing around the edges.

The biggest difference of course is that this is basically croutons.

The bread in our vacuum chamber.

While moldy and not really fit for consumption,is still completely squishy.

Like there has been no loss of any of the moisture.

Not going to eat it because of that.

I'm also not going to eat this one,and that's not because of the mold so much as it is because this is no longer breadfit for human consumption.

And this smells bad.

That's going back in the jar.

Potato chips sitting open in a jar.

They're so stale.

Vacuum chamber chips.

Taste like you just opened the bag.

I don't know if I can really showthe breakages different with a stale chip.

I mean they both break but that one is softer and taste bad.

That one is much crispier and taste delicious.

Apples, right away you can see that things have transpiredwith the apples.

The ones in this container have obviously losta lot of moisture.

There is some mold forming.

The peels have become all shriveled, the apple in general has justbecome shriveled.

It's dehydrated a fair amount and there is some mold growingon all parts of it.

Obviously not something that we're going to eat.

Our vacuum chambered apples don't look like they've really lost much moisture.

Maybe a little bit, we saw some of it even getting suckedout of the apple when we put it in a vacuum in the first place.

The other biggest difference is that these have a lot more mold on themand I think that's probably because they still haveall of their moisture.

The dried out apples, don't get as moldy.

The apples that just sit cut open but have a lot of moisture in them.

Mold central.

Now we have milk.

This jar has been sitting open in the refrigerator.

You can see that the level of the milk has dropped.

It's dehydrated that much whereas, this one I don't think that's changedits in the same spot that it was before.

There's like lines on the walls but that's from when I carried itto the fridge and it just swirls a little bit.

So first test.

That doesn't smell nearly as much as I thought it would.

This is well expired milk at this point and a lot of the time when milk goes bad,it smells terrible.

You can smell it easily and from a distance.

But this,really doesn't have a smell.

Unfortunately, I am not brave enough to try drinking that.

You can see a little bit of stuff has formed on the surface.

I don't know how to describe it better than that.

I think that's probably some kind of mold.

Maybe that's just the formation of the the milk solids.

How it happened to form up.

All right.

So this,actually has more smell and it doesn't smell rotten.

It just smells like milk.

I'm going to try mixing this up a little bit.

All right.

Trying and be brave here.

It's not still good.

Like it has a little bit of that butter milk tasteif you've ever tasted buttermilk.

It's maybe getting just a little bit sour.

If you've ever just had milk that's gone badlike you accidentally poured a cup of it or in your cereal like it's disgusting.

You want to spit it out and maybe go vomit right away.

It doesn't taste like that.

But I'm impressed at how well it preserved this one.

That is about three weeks past expiration now.

Grant Feltz what you askedis if food will get stale in a vacuum chamberand I think that we have demonstrated that in terms of just going stale,a vacuum does a really good job.

Our graham crackers and our potato chips taste like they're completely new,they haven't gone bad at all, and I think that this isa decent way to preserve them.

I don't know that it's any better than just keeping themin a sealed Ziploc bag or something like that,but this did work.

The bread did not go stale.

It did keep that from happening but it did not prevent it from rotting.

This has mold all over itand is definitely not edible.

Same thing with the apple.

It didn't dry out but it did go bad.

It's moldy and you can't eat that.

The milk, I think it probably preserved it somewhat.

It didn't go bad as much as this one which I admitI'm not willing to taste because yuck.

But it's still not good.

So, keeping it from going stale.

Yes it does.

Keeping it from going bad in all situations,no it definitely does not.
