how supercritical fluids give you decaf coffee

[rJaune]

If there is supercritical CO2 on Venus we may have our first interplanetary export. Aphrodite Coffee! Ha

[Flesh_Wizard]

Conclusion: we need to put all the coffee on Venus

[MaheerKibria]

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.

As somebody who regularly drinks decaf I'm sorry to inform you that doing this to green coffee still impacts the flavor.

[evanherk]

temperature doesn't have to be very high for CO2 supercriticality - from about 30 C, which is below body temperature

[DrDuckMD]

Otherwise known as CO2 extraction. If you smoke the devils lettuce, this is how they extract the oil from the plant material. That’s used in thc vape cartridges. It’s the same process and the CO2 evaporates off leaving the oil.

I've always wondered this. Thank you

This is one method to remove caffeine there are also other solvents that can be used to remove the caffeine

[andylarson]

Very well explained and articulated!! 👏👍

[AjaxWolf]

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

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

[nuniobinez]

So, does this process finally make it taste like regular coffee?!?

[AaronnaPhiliou]

Is this the same process for removing caffeine from tea leaves?

[justmenotyou]

SuperCritical!! So that's how my girlfriend harvests my soul. Tears it out and leaves a void behind. 😢

Thank you!!! I finally know how they make that instant coffee :D

I was just trying to get chatGPT to visualize the caffeine molecule. Is this just synchronicity, or is it cookies?

[numberlover]

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.

[OctagonalSquare]

I was LITERALLY just wondering how they do this last night

[cheddarsock]

I did this backwards. Ive seen the experiments, but didnt know there was a practical use for it.

[andiralosh]

Hmm, wonder if it works the exact same for tea
