I been trying to find info on this new decaf method since hoffman reported on it month back thanks for your quicker explanation, have you tried it yet?! It seems like the super high temps they subject it to would make it taste off?
I believe he was trying to generalize it. For other fluids, It’s generally a very high temperature, And compared to CO2’s normal liquid temperature... It is very high.
Dude are you an American? Super critical point consists of temperature and pressure. If it was only 31C, your blood vessels would burst during summers and spring. It’s interesting how the lowest IQ ones are also the most confident ones.
It’s not about instant coffee, it’s about decaf coffee (no caffeine, same taste and process of brewing). Instant coffee is made by dehydrating already brewed coffee.
Also be warned if your sensitive to caffeine, decaf can still get your feeling horrible and overstimulated. There is still a good amount of caffeine inside (for people who dislike caffeine)
I'm fairly certain they did and that's what most decaf coffee actually is just a specifically bred coffee strain that just doesn't contain caffeine in the first place. Because ykno doing all this other jazz to remove the caffeine isn't worth it for most in the long run when it's literally cheaper to just spend the initial investment into selectively breeding the coffee to not produce caffeine.
@@markopolo1271 I know for fact that all decaf is made by removing caffeine from the raw coffee beans with some kind of solvent. And even tho this process has become a lot better in recent years, it is expensive and you always lose something. There are some specific varieties of Arabica which are a bit milder but a caffeine free or very mild bean does not exist. Maybe pests become a problem...

There’s another more natural way to decaf called sugar cane processing, you take fermented sugar cane and just dip the raw coffee in it. The sugar cane draws out the caffeine and keeps more flavor
If you take the caffeine out beforehand, isn't there a chance that the similar chemicals that you're worried about removing, won't be made in the 1st place. I assume many start out as caffeine, and then change into something similar.
Caffeine molecule is polar molecule. One side of such molecule is more positively charged. CO2 tends to attract such molecules on itself. So CO2 works like kind of magnet that sweeps through the coffee beans. CO2 does do the same for many other molecules, but process conditions effect greatly on how strongly these "magnet" forces work. And process can be engineered to fit almost perfectly to whatever application.
I'm just an amateur chemist who's preferred coffee is : instant coffee, 5 spoons of sugar and half milk half water, but I'm pretty sure you mean pressure not temperature, CO2 is supercritical at quite low temperatures but high pressure, and in this instance you can't substitute pressure for temperature, all of it have to be just right, but other than that there's more easier ways to extract caffeine from coffee at home as NileRed would know but ye CO2 probably works best on industrial scale cyaaaaaaa

They do the same for weed when making CO2 extracts it's very potent but loses allot of other stuff like turpines which is why live resin and CO2 extracts give different highs
Unfortunately a lot of the flavor of coffee comes from many molecules that are of a similar mass and size/shape as caffeine, think theobromine & theophylline and other methylxanthine acids. pCO2(g) being nonpolar stripes all of that out, leaving decaf tasting terribly.
I could see it being extremely useful if it didn't destroy the extracted Caffeine in the process, so that you could just filter it out from the condensed CO2 - especially if the same technique could be used to selectively extract other Alkaloids (which are some of the most useful substances in nature, eg: Morphine, Psilocybin & Quinine) from various substances. Hell, you could even remove both the Caffeine & Theobromine to make dog safe Chocolate.
Well, no Supercritical is a state it is in. Just like liquid or gas. Build the pressure of a gas and raise the temperature until the surface between the two fades.

While you can use super critical co2 this is almost never done. Too expensive usually swiss water method or chemical solvents are way more common.

true. it leaves a clean, tasty product🥰 😋 💨💨💨
As somebody who regularly drinks decaf I'm sorry to inform you that doing this to green coffee still impacts the flavor.
This is the new way that they're extracting THC and CBDs from cannabis. It's called live resin and it's amazing. Just thought I'd point that out.
I'm listening, tell me more?
Live resin has been around for at least a decade it's not new.

temperature doesn't have to be very high for CO2 supercriticality - from about 30 C, which is below body temperature
Exactly. Too high temperatures would carbonize the bean and foul the flavours.
Very well explained and articulated!! 👏👍
This is one method to remove caffeine there are also other solvents that can be used to remove the caffeine
Soaking the green beans in water before dehydrating and further roasting. One of the oldest and most simple techniques.
Can I get that leftover caffeine?
*Mass Spectrometry has left the chat*

The critical point of carbon dioxide is 31C, not very high.

It depends on pressure.

We use DCM
I just dont get the point of decaf if you dont want caffeine just drink milk or something 🤷
Thank you!!! I finally know how they make that instant coffee :D
It’s not about instant coffee, it’s about decaf coffee (no caffeine, same taste and process of brewing). Instant coffee is made by dehydrating already brewed coffee.
Two words: dichloromethane
WHY TF WOULD YOU DO THAT?
How the F-stop do you learn this stuff? Like if I wanted to make a 2 step poison, how would I get a BA in this topic?
I did this backwards. Ive seen the experiments, but didnt know there was a practical use for it.
With chloroform, or any solvent which where only the caffeine is soluble.
Also be warned if your sensitive to caffeine, decaf can still get your feeling horrible and overstimulated. There is still a good amount of caffeine inside (for people who dislike caffeine)
So, does this process finally make it taste like regular coffee?!?
Is this the same process for removing caffeine from tea leaves?
Or don’t bother with any high pressure equipment and use solvents, i think nilered had a video about caffeine extraction
Does the process create lots of freeze died caffeine concentrate?
Wish they could just come up with coffee plants that produce less caffeine.
I'm fairly certain they did and that's what most decaf coffee actually is just a specifically bred coffee strain that just doesn't contain caffeine in the first place.

Can i get some water carbonated with the caffeine infused super critical co2?
Hmm, wonder if it works the exact same for tea
Clever science and all, but decaffeinated coffee is an abomination from the pits of hell.
Can that extracted caffine be separated from the co2?
It is deposited when the chamber depressurizes
There’s another more natural way to decaf called sugar cane processing, you take fermented sugar cane and just dip the raw coffee in it. The sugar cane draws out the caffeine and keeps more flavor
So do they use that caffeine in monster and other products? Is the fact that its CO2 convenient for carbonated energy drinks?
I was just trying to get chatGPT to visualize the caffeine molecule. Is this just synchronicity, or is it cookies?
After the caffeine is extracted, what do you do with it? Asking for a friend.
You can do the same thing for THC
Can this be done with Marijuana? 🤔
Do they always use CO2

I Never understood why you would want coffee without caffeine.
I do it using a grinder and hot water in the morning
Is this how they make decaf?
Fascinating!
I thought you just hit it with a Swiss mountain.
very interesting thank you for that
The real ones use cloroform and column cromatography.
I want to know what happened when they tried to run it using roasted beans. Any possible new flavor compounds?
I cringe every time I see that paper towel roll dangling precariously over the toaster oven
I flee like it would be easier to selectively breed beans with progressively less caffeine.
Less caffeine =//= caffeine free
This is how illy decaffeinates their beans. Much better and fuller flavor than solvents or water process.
So uh I was eating Wasabi Seaweed snacks yesterday, and was like shit these are salty AF. To bad we couldn't have a process to get rid of salt in foods.
Then I sipped on some coffee, and was like well they can decaffeinate coffee. Pretty sure it is a process and not growing a different selectively bred bean. I should look that up anyway.
Then tonight this video pops up! Whoa never would have guessed the process even if you hinted at it. For one I always forget supercritical is a thing outside of a bad day at a nuclear reactor, but just that it can dissolve chemicals through membranes. That is really interesting.
Now I shall see what else uses other uses for making things go supercritical for industrial purposes.
I thought you used butane
Does it extract or destroy it? If extracted that’d be a great way to naturally vaccinate other products rather than anhydrous
You veritasium and Nile red should do a collab together
I wonder how thngs like this were discovered?
So what you saying is the distillate is just caffeine
They do the same for weed when making CO2 extracts it's very potent but loses allot of other stuff like turpines which is why live resin and CO2 extracts give different highs

Next time I roast beans I’ll remember to process them first…
I doubt that caffeine is the only chemical that is removed. Nothing is that selective.
That's also how you make really good and clean extractions from marijuana
Somebody get this guy hooked up with NileRed to work on his decaf Red Bull.
Hmm, such beans coming to a store near me, I hope.
Pretty sure most decaf coffee is just a strain of specifically bred coffee tree's that never had caffeine in them in the first place
Me realizing that 2% of the 15g of coffee I take is the max I can go: fucking what?!
Why would you take the caffeine out of coffee? That's like taking the THC of out weed.
Isn't there like a chemical process for producing caffeine so you can skip growing beans just extract chemically pure caffeine.
This is crazy talk! Why would anyone want to take caffeine OUT OF coffee.??
...
Just for fun
I love the evidence left in the way this comment was written.
You forget the how… can we get some solubility values, reaction conditions, times, apparatuses, demos, or animations
I wouldn't say super high temperatures. I mean, I don't know what temperatures they use, but even 35 degrees Celsius is enough to go supercritical
SuperCritical!! So that's how my girlfriend harvests my soul. Tears it out and leaves a void behind. 😢
I knew there was going to be a comment like this on this video. Excellent!
Damn 2%? It just my smooth brain or is that a poopton as far as active ingredients go?
its not completely rid of caffeine however
Are you sure that the supercritical CO2 has to be hot? I’m pretty sure I’ve seen super critical CO2 at room temperature.
If you have low self-esteem stay away from supercritical CO2
If only coffee processors would actually use this non-toxic method. It’s much cheaper to use methylene chloride. 🙄
I could see it being extremely useful if it didn't destroy the extracted Caffeine in the process, so that you could just filter it out from the condensed CO2 - especially if the same technique could be used to selectively extract other Alkaloids (which are some of the most useful substances in nature, eg: Morphine, Psilocybin & Quinine) from various substances.

Super high temperatures and pressures. Well, it’s slightly above room temperature but okay. High pressure is correct
Still tastes different. Must be the addictive property of caffeine
Nah he is just wrong. It doesn’t just pull out caffeine, it pulls out tons of other chemicals too that are important to the flavor.
This is how decaf coffee is made?
Yep!
Isn't that just the Swiss Water method...
