Will Food GO BAD in a Vacuum Chamber?

A slew of meat croaks stale or shitty when it’s exposed to air or humidity. What happens if stay in a vacuum enclosure where it doesn’t have either one?

YouTube user Grant Feltz asked if the food would get stale in a vacuum enclosure? Grant that is a great question and we would love to try that out. So today, we’ve got a variety of meat that goes bad when they’re left out. We’ve got some flasks that we’re going to try and turn into big vacuum assemblies with the meat in them and envision what happens to that meat after a couple of weeks.

Here’s what we’re going to try. We’ll modify these flasks so they can hold a vacuum with the meat inside. We’ll have some meat in the vacuumed containers as well as retaining some meat out of the flasks as a controller. After two weeks, we’ll see what’s happened. We’ve got five different meat that was going to experiment, so let’s take a look at them. First, we have a couple of apples. We’ll trim these into wedges. One assortment of apple wedges will go into a jar with all the air sucked out, and another batch of apple wedges will still go in a container, but we’ll leave the lid off. Hopefully, we are going to be able to restrain too many fruit floats from experiencing it. We may end up putting a slight cloth impediment to keep them out. We’ve got some milk with an expiration date of fewer than two weeks from now, and we’re going to put some of it in the container in a vacuum, and some of it merely leaving in the bottle, and tell it to sit for “two weeks” and see what happens. Graham crackers are something that I anticipate get unusually noticeably stale pretty quickly.

If they’re fresh, they undermine reasonably quickly, they’re pretty crumbly, and they have a nice crisp crunch to them. Ordinarily, if you leave them out, they get actually soft, virtually mushy. You can’t even really click them. They virtually bend. So we’re going to try some graham crackers in a container. And some graham crackers babysit on a dish. Potato microchips, far-famed for coming in pouches full of air will too go stale if you leave them out. Now a great deal of potato chip pouches actually come full of nitrogen rather than regular air. And that’s because the nitrogen doesn’t react as much with the microchips inside, and we’re going to give a likeness between collecting microchips with nothing, not even nitrogen, and merely leaving the crate open. These aren’t stale yet. Luscious! Lay’s that will be 1 million dollars. Lays? Lays? Dang, it. And lastly, we have some light bread. Bread if you leave it out, it frequently gets merely really really cold at least in this atmosphere. We’re going to see if the same circumstance is happening in a vacuum enclosure. We’ve got all our meat laid out. So it’s time to start concluding our vacuum jars.

And we’ve done something similar to this before. We made some glass soda bottles, instructed a small excavation in the cover and had a piece of rubber that baby-sit over that excavation. We put the whole circumstance inside our big vacuum enclosure. And the air can be do sucked out of the container when we are exerting pressure back in, that rubber seal gets pressed up against the hole, retaining it neat and shut. So that’s what we’re going to try doing. We’ve got some of these big flasks so we can fit a right amount of meat in it. Let’s see how it cultivates. Now we’re exerting some electrical strip to remain this rubber in place. We’re not trying to hold it down. We want it not to go anywhere. So I’m not pulling the strip tighten. I’m not pressing it down over the whole circumstance. We still require air to be able to escape out past this rubber and then have it various kinds of sucked down on ones there’s low-pitched stress in the jar.

Let’s give this a test. Beautiful. We made the air back into the primary container, but the rubber stopper frustrated it from replenishing the little container. Now I think if we peel this stopper away, we’ll examine the air and watch the marshmallows downfall a bit. Or a great deal. Yeah. Yeah, I’d say that’s working pretty well. Wonderful. All right we are going to be able to fit whole graham crackers into this jar.

So I’m just going to shed a duo in there. The whole slice of bread does not fit in, but I’ll just cut it in half. And I think what’ll be the best experiment is I’m just going to put half of it into the container and leave half of it in the other bottle. That room there is some air in the bottle. A right side by side doesn’t expect graham crackers are going to do a whole lot in a vacuum.

That already has humidity in it. The sides of that have started glooming up, and I’m pretty sure that is humidity leaving the eat. Look at all that humidity cleared up too. Ooh. It is boiling. The liquid has appeared to be get attracted right out of our apples. It’s kind of hard to keep them in zero stress and restrain all the liquid in place. So, the results on the apples may be a little strange. I think in the minds of the concluding everything as equal as possible, trying to eliminate variables we’ll place the onion vacuumed explanations in flasks, but with the eyelids off. Why was it pressurise? Why are they all pressurise? With the apples, I am going to set a piece of paper towel over the top.

Maybe even tried poking some pits in it. I require there to be good air exchange, but I too don’t want to fill the members of this house with fruit floats. Now we’re going to set these aside for two weeks and envision what has changed. The milk will be included in the refrigerator — both of them. Everything else will just be sitting out. Time has now passed and more time than we originally planned. We were going to go for two weeks. And then we just got busy with our planned filming other videos. So it’s actually been four weeks that we’ve told these thoughts to sit out which is a slew of time for trash to go wrong.

Let’s see how things are. We’re going to start by merely popping all of the seals, and we’ll see it’s possible that we haven’t obstructed a high vacuum on all of these. But we’ll be seen to what extent much air seems to rush in as we undermine the seals on them — side-by-side experiment. Graham cracker baby-sits open in a container for a few months. It does have a little bit of click to allow them to it — not much. And it unquestionably smacks like an old-time graham cracker that’s quite stale. Don’t really must be considered graham crackers is something that started savour bad but that was really not pleasant. Much more crumbly as it crackings. Much crisper. And a lot more crunchy. You can actually hear that when I squish it and reaches like crunching phones and this one merely kind of slushes. This one snaps apart in the crumb. So graham crackers drove really well. Now the eat I already know I’m not going to do taste tests because there’s mould on both of them.

However, the mildew on the open one, very minor. There’s just a little bit increasing at the edges. The most significant gap, of course, is that this is basically croutons — the eat-in our vacuum enclosure. While rotten and not really fit for consumption, is still totally squishy. Like there has been no loss of any of the humidity. Not going to eat it because of that. I’m too not going to eat this one, and that’s not because of the mildew so much as it is because this is no longer eat fit for human consumption. And this smells bad. That’s going back in the container. Potato microchips baby-sit open in a container. They’re so stale. Vacuum chamber microchips. Smack like you just opened the crate. I don’t know if I can indeed evidence the breakages different with an old chip.

I mean that they both break-dance but that one is softer and feeling bad. That one is much crispier and feeling savoury. Apples, right away you can see that things have percolated with the apples. The ones in this receptacle have evidently lost out of humidity. There is some mould form. The peels have become all shrivelled, the apple, in general, has just become shrivelled. It’s dehydrated a fair amount, and there is some mildew growing on all regions of it. Undoubtedly 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 find some of it even get sucked out of the apple when we put it in a vacuum in the first place. The other most significant gap is that these have a lot more mildew on them and I think that’s probably because they still have all of their humidity. The dehydrated out apples, don’t get as rotten. The apples that baby-sit trimmed open but have a lot of moisture in them. Mould centre. Now we have milk. This container has been sitting open in the fridge. You can see that the level of the milk has plummeted. It’s dehydrated that much whereas, this one I don’t think that’s changed it’s in the same place that it was before. There’s like arguments on the walls, but that’s from when I carried it to the fridge, and it merely twirled a little bit.

Such a first experiment. That doesn’t smell nearly as much as I thought it would. This is well-expired milk at this pitch and a great deal of the time when milk croaks terrible, it smells dreadful. You can feel it quickly and from a distance. But this doesn’t have a smell. Regrettably, I am not brave enough to try to imbibe that. You can see a bit of trash has structured on the surface. I don’t know how to describe it better than that. I think that’s probably some kind of mildew. Maybe that’s just the formation of the milk solids. How it happened to words up. All right. So this, actually has more smell and it doesn’t smell. It just feels like milk. I’m going to try desegregating this up a little bit.

All right. Trying and be defied now. It’s not still good. Like it has a little bit of that buttermilk feeling if you’ve ever smacked buttermilk. It’s perhaps got just a little bit sour if you’ve ever merely had milk that’s gone bad looks just like you accidentally poured a cup of it or in your cereal like it’s disgusting. You want to spit it out and perhaps start vomiting straight off. It doesn’t feel like that. But I’m impressed at how well it retained this one.

That is about three weeks past expiration now. Grant Feltz what you asked is if the meat will get stale in a vacuum enclosure and I think that we have demonstrated that regarding should go stale, a vacuum does a really good errand. Our graham crackers and our potato chips savour like they’re entirely new, they haven’t gone wrong at all, and I think that this is a decent room to preserve them. I don’t know that it’s any better than just keeping them in a sealed Ziploc bag or something like that, but this used to work. The eat did not go stale. It did restrain that from happening, but it did not prohibit from rotting. This has mould all over it and is definitely not palatable — the same circumstance with the apple. It didn’t dry out, but it did go wrong. It’s mouldy and you can’t feed that. The milk, I think it probably retained it somewhat.

It didn’t go bad as much as this one which I admit I’m not willing to feel because of yuck. But it’s still not right. So, retaining it from travelling stale. Yes, it does. Impeding it from going wrong in all situations, no it unquestionably does not. Concede thank you very much for your great thought of something technical we could try out exerting our vacuum enclosure. If you check your YouTube inbox, we’re going to be sending you 25 bucks. And guys remember, if you’ve got a good thought, tell us to know down in his observations, and if we use it to make a video, the authorities concerned will send you $25. Guys that’s not all. We’ve always come more for you see.

That box up at the top will give you directions to our last-place video. You should go check that one out. The other chest will show you what YouTube thinks you should be watching next. And if you’re not a subscriber, affect this bombard to get in the sorority and that room “you’ve never” miss out on a video. Don’t forget to peal that bell and we will see you in the next one.
