What do you think of umami taste like fish and cheese and other stuff and the spice "taste" with the Scoville heat units like Jalapeños and the coolness "taste" with mint? I'm not exactly a fan of sweetness. I'm more of a salt and umami and spice guy. Except for drinks. I like sweet but not overly sweet drinks. I like soda because it's bubbly. I like pickles. Sometimes I would eat pepperoncini or hot cherry peppers but Jalapeños are even spicier unless you put it in a sandwich or burger where it's good. Serrano is way too much. Serranos are so hot I can't eat half a Serrano not even my brother who's the spice king can handle Serrano. Johnny Scoville from chase the heat can handle Carolina Reapers.
NO, I am not sticking my tongue in that! For the same reason I never went through with the tongue split. (well actually i never did that cuz one slice is often not the only slice you will need and that just doesn’t sound fun. ). 😂🤣 I love this channel though. You folks are awesome!
I really enjoyed this episode, thanks George and crew! I'd been under the impression Salt Receptor 1™ was all there was to the sense of saltiness and wasn't aware of the cross-taste interactions. But finding out there's a lot more we don't understand is always a pleasant surprise. Who knows, maybe this video will spur someone to go on to do research on this and expand our understanding a little more.
If wikipedia is anything to go by, KBr has a sweet taste when dilute, bitter at moderate concentration, and salty at high concentration, while NaBr is salty across the board. Otherwise, there have not been enough tests for the impacts of NH4Cl, SrCl2, RbCl, MgCl2, or CaCl2, for example.
What a joy to see this video! As a fellow scientist, loved the approach and depth of analysis. Will definitely try some of the experiments just for fun! Congrats for the production!!
I've always put salt on grapefruit because it made it taste so much better,, I also eat lemons with salt, although I don't do that nearly as much as when I was younger (my dentist was always horrified that I did that, but I absolutely love sour stuff)
You tried the KCl second. What colors you perceive are affected by what you looked at before, what it is next to, and what the coloring of the whole "scene" is. Isn't how you taste KCl similar to whether you saw a blue or a gold dress?
I think if the whole chemist thing falls through, you could be a comedian! Thanks for digging into a subject I didn't know I wanted to know and the real laughs.
Great video👍 May I suggest a solution here, that is out of the box for chemistry, but so happens to be informed by ancient wisdom that dates back to Vedic scholarship some good 5,000 years ago. Consider this in an ascending order from heaviest to lightest: 1. Sweet = Earth + Water (cohesion & solidity) 2. Salty = Earth + Fire (dehydration) 3. Sour = Fire + Water (digestion & transformation) 4. Pungent = Fire + Air (combustion) 5. Astringent = Air + Earth (conduction) 6. Bitter = Air + Ether (dissipation) Provided that Salty molecules consist of the heavier elements of Earth & Fire, they overwhelm the lightest elements of the Bitter molecules that are primarily composed of the lightest elements of Air & Ether. However, if you separate the two sets and introduce them separately, they will have a lesser effect of elimination of Bitter by Salty, because they would have to undergo a digestive process to result in this elimination. So, if we combine the Salty with Bitter prior to tasting it, the “pre-digestive” process begins before the tasting process, and Bitter is easily broken down by Salty, or more accurately overwhelmed, or suppressed. So, bitter tasting compounds are the most delicate in nature, while the Salty one are far more stable and consequential. Taste is an essential characteristic in determining the properties of any ingredient. Pre-digestive taste (what we perceive prior to the foods descending into our stomach where it meets the digestive acids) has the 6 above mentioned elemental combinations. But, the post-digestive effect carries only 3 possible tastes: Sweet, Sour, Pungent. Where do you think the Salty, Bitter and Astringent went? All foods with sweet post-digestive taste are nourishing, while the purifying or reducing foods are pungent in “after-taste”. This may not provide us with chemical proof of existence of the “salt receptor 2”, but it may answer some questions as to the mystery of how bitter dissipates in the presence of salty. Do you find this a curious way of looking at the same dilemma?
Wow, that somehow did not occur to us the whole time we were making this, but that's a fascinating question. Obviously the fats and sugars play a huge part, but you would think that the salt must factor in, as well. Now we're going to spend the rest of the day trying to think of a way to test this...
@@ACSReactions, what about using coconut milk (the stuff for cooking has very little salt in it) or making your own nut/soy milk (store bought has a lot of salt in it)? Both of these would have the fat and sugar content w/o the salt and it would allow you to do a blind taste test (add salt to some). I'd suggest trying it on peeps that add this stuff to their coffee anyway to avoid being distracted by the novelty
In your dislike of IPA's, you've identified the reason for their popularity- they go remarkably well with salty foods in hot weather where we're often craving salt due to loss via perspiration. The hypothesis then, might be that bitterness increases intake of 'water binding' compounds like sugars, acids, and salts.
I'm so glad that my creative obsession is with the visual arts rather than the culinary ones. Vision is just, so much better understood than taste, in terms of how it mechanically works.
I've heard the thing about adding salt to coffee years ago, but dismissed it. This video convinced me to at least try it because it went beyond just an old-wive's-tale, it actually tried to prove it's not just a placebo. That said, I wish George had actually specified HOW MUCH salt to add to coffee (what's a "pinch"? is it to a cup or pot?)
There's a couple of variables which can't be isolated which contribute to this quandary: how the sense of smell interacts with the sense of taste and that our senses are difference engines. When eating/drinking we are also smelling the environment (including that which we are consuming) adding to the noted brain involvement. Some people can consciously smell when the air changes salt content. The "difference engine" part is where our senses align with the current environment. We don't smell or taste ourselves to enable us to better detect the environment. That means we have to "cleanse our palette" between tasting different things. Like at a wine tasting, where items used to cleanse are favorable to tasting wines. Unfortunately, when tasting something as basic as salt, what would we use to cleanse that wouldn't upset the balance? I think if that solution & protocol can be determined testing would achieve breakthroughs.
Oh, my gosh. Denatonium Benzoate does taste really terrible and it lingers on the tongue. I think it was one of your videos where they said that toddlers was more likely to like the taste of antifreeze with the bitter substance in it. Also it did not work as an deterrent when my bunny was chewing on its cage, rather it had the extreme opposite effect 😫
Early in the video and I think I see your problem. As you allude to with C=N, chemistry and biology often look like strange bedfellows. The dynamic nature of living organisms, and our ability to compensate for, and exist in variable ranges of environment is incredibly complex. That's why med school takes so long. My guess is that 'perception' is the end product of a complex array of sensors (taste, smell, texture, look, context) filtered through a processing system (I like bitter, I don't like sour, I have never tried mushrooms, I once ate a slug and became ill therefore slimy food evokes emesis). There are probably factors such as: Age: Senescence and tolerance Sex: Because Sodium intake: Possible that you crave NaCl when low. Hydration status: Possibly alterations in perceptions of NaCl when dehydrated generally. Other electrolyte balances/status: See above. Temperature: There may be prophylactic sensors that predict that we will require >NaCl in hot environments due to loss via sweat. You also have to realise that we are dealing with neurons to convey messages here. How does a neuron propagate a signal again? Sodium Potassium pumps IIRC. --------------------------------- Oh, yeah, you addressed some of this. Nice. The tasting 'everything' makes sense if you take into account that salt may be directly affecting signal propagation. Perhaps it doesn't interact with the receptor itself. The complicated interactions it has with various neurons that distortions in that balance lead to random misfiring. @ 9:00 loving this video! ----------------------------------- Yeah, would make sense. So there are sodium channels, but does it have to be a receptor? Is there no way for salt to cross cell membranes with other ions? Again, I honestly feel that if you were hyponatremic, you would either taste the NaCl differently. And you would prefer it to KCl.... could totally be wrong though. Maybe the 'taste' is just the neurological consequence of changes in ion concentrations in various regions on the tongue? Wait... don't we also have taste receptors on our anus? How do they react to salt?
My father was a chemist and one day he brought home "Bitrex" witch is the trade name for that long chemical name. Anyway I had a small jar . A friend of mine thought he was cocky and wetted his finger and dipped it in the jar and put it in his mouth. He instantly ran away towards his house. He later said he drank all the milk in the fridge and still couldn't get the bitter taste away. I tried it too, but a lot less.
I recently fell in love with this channel -- but, if I may, BRING US MORE ANDREW CONTENT!! alongside George and our other hosts, ofc, but if I may hype the underdog BIG FAN OF ANDREW CONTRIBUTIONS! regardless, keep it up, team!!
This is so interesting, I sometimes feel that I can switch salt by a bit of lemon juice and somehow it still tastes salty. Turns out my brain is crazy or something.
Works with cocoa too, except it only matters if you're a crazy person like me who likes their cocoa incredibly strong. Most people's cocoa mask the bitterness with massive amounts of sugar, but if that's not your thing, try the salt trick.
Right off the bat, and I'm serious, I haven't watched any more of this from this moment... James Hoffman (sp?) did not recommend salting coffee. I just watched that episode, and I'm not a coffee snob but I am a coffee addict, so I found the idea interesting but I'd never try it. I love my coffee straight black and dripped automatically. JH being the most reasonable coffee snob I know of though, I had to see his point of view on it. He said there is a marked difference in the bitterness of the coffee, but even a little salt adds a clear saltiness to the coffee, which is not great. He recommended better coffee, but if you have to endure terrible coffee (and this is usually something like robusta, not arabica), salt could help if the bitterness is worse than the saltiness. He definitely didn't recommend it 😂
The common denominator of NaCl and KCl is the negative chloride ion. I wonder if there is an interaction there with the taste receptors / taste receptor 2? #nobelprizeincoming
Has anyone done tests where instead of asking people what they taste, that instead they monitor the strength of the signal along the nerves? (maybe that's not possible, idk)
Thumbing through the PDR, you'd notice that under "Mechanism Of Action" for 99.9% of all drugs, its 'unknown' (*for their specified on-label use). I always found it odd that we just use these medications even though we don't know exactly how they work, just that they do in fact work.
Mmm... no. That isn't correct. I'm just a lowly RN, and I still understand the most commonly proposed MOAs of all drugs I administer. Even ones like Lithium Bicarbonate have been extensively studied... it's just that we can't know with 100% certainty. Still, the number of times I have heard that 'we have no idea what the true mechanism of Lithicarb is' is as silly as it is incorrect. The only thing I can think of is actually SSRIs. Even then, we have multiple theories on how it may work. Just no certainty. Everything in biology is a range, that's why chem and physics majors struggle. Ironic seeing as though electron shells exemplify the same concept.
@@user-um2uf9zq4c agreed! I'll admit, 99.9% was a pretty gross # to throw out there. As with the physics regarding the electron shells; we all know how an electron can jump orbitals then dump that needed energy to go back to a rest-state - it's pop-sci at this point. Despite that, you could still do your post grad research on the topic as the further you dive into most any field, the more complex and 'unsimplifiable' it gets. I appreciate that you can give a reply with knowledge that stems from practice.
@@BlackWolf42- Oh, wow... I didn't know that. :( Sigh... one of these days I'll go back to Khan academy and redo physics. My understanding went as far as probabilities. Which is much more analogous for humans. We can't DNA test everyone, we have no idea how people metabolise drugs (especially horrible prodrugs like tramadol) until we use them. We are very much still living in the prehistoric era in healthcare compared to what 'science' is 'capable of'. Money is the name of the game.
On that matter, the thought did strike me that that there could be a way to narrow down Salt Receptor 2. Namely, see if potassium solutions with something other than chlorine as the anion still taste salty, and whether nontoxic chlorine solutions with a 2+ ion still taste salty. This could establish whether Channel 2 is reacting to chloride, or whether it's still responding to +1 ions while being less picky than the sodium channel.
salt to taste salt for the little hole in that face better go thanks to the little bird that let me know that’s not you how’d he tell you to, i found you what you when you he’s all talk he’s just playing cards at the boardwalk watch that frown talk just a little bit, to calm you down
errr ... have you ever thought of adding sugar to the coffee? Like ... 1 teaspoon of sugar only. Or maybe change coffee quality ... or most probably, remove all limescales from the kettle. This is not science ... it called "COMMON SENSE" .... I know ... we (they ... you) lost all common sense in these last 2 years.
Being a scientist, normally I do not post salty responses to YT vids but if ever there was a moment to remark that a video left a bad taste, this HAS to be it. Because around 11:06 when the host calls out the unresolved "mystery receptor' so elusive amongst the 'taste community' I laughed so hard my salted coffee gushed through my nose. I was thinking by that point, If Na+ has a well-understood salt taste mechanism 1 ... Then.... WHAT oh WHAT could salt taste mechanism 2 possibly BE??? Uh, just what else is in that there salt? Oh chloride you say? Right... MAYBE just MAYBE could there be a chloride-related mechanism?? Turns out, the fifth result on the first page of Google Scholar for search terms "chloride ion receptor taste" right now is this research out of Tokyo confirmed the same, released earlier this year : www.biorxiv.org/content/10.1101/2022.02.23.481615v1.full.pdf It's not precisely a chloride channel as it is with sodium, but rather that chloride blocks taste receptors for sweet and umami that which provides a second major salt taste mechanism. Somehow, sometimes the preposterously obvious is really quite elusive isn't it? After seeing George demonstrate on-screen that KCl tastes almost the same as NaCl, is it odd it didn't occur to anyone creating or consulting the show that there might be a Cl- mechanism? Perhaps a follow-on video could be warranted. And if so, maybe you can also explain how the 'taste community' ... missed this possibility? Maybe we could have a chat with that study author, a certain Atsuko reachable at a_yama@okayama-u.ac.jp And ask how the elusively obvious idea came to him?? I'll leave my fellow comments section readers here to judge whether salt really can make almost anything taste better, including this YT comment :-) And to the video creators, good work keeping us engaged in the topic long enough to want to follow a hunch your vid brought up!
Fair points. Could be the mechanism. Could also be a combination of that with many other mechanisms working in concert, as is typical in human physiology. Your comment reads a little supercilious though.
We have a pretty good understanding of how other tastes work, especially sweetness. Salt is just so damn… elusive.
What do you think of umami taste like fish and cheese and other stuff and the spice "taste" with the Scoville heat units like Jalapeños and the coolness "taste" with mint? I'm not exactly a fan of sweetness. I'm more of a salt and umami and spice guy. Except for drinks. I like sweet but not overly sweet drinks. I like soda because it's bubbly. I like pickles.

Like America needs more salt. Some things should remain secret.

This could establish whether Channel 2 is reacting to chloride, or whether it's still responding to +1 ions while being less picky than the sodium channel.
2 salt 2 receptor
BUT ALSO salt is healthy to have if you have a defficiency of it in your body lol
We are the salt of the world.
This is why you take salt and lime with tequila.
*cheap pungent tequila
@@eaterdrinker000 pretty sure even good tequila is made better with salt and lime.
salt to taste
salt for the little hole in that face
better go
thanks to the little bird that let me know
that’s not you
how’d he tell you to, i
found you
what you
when you
he’s all talk
he’s just playing cards at the boardwalk
watch that frown
talk just a little bit, to calm you down
This boy just said IPA's suck..
What else can I do but DISLIKE??
errr ... have you ever thought of adding sugar to the coffee?
Like ... 1 teaspoon of sugar only.
Or maybe change coffee quality ... or most probably, remove all limescales from the kettle.
This is not science ... it called "COMMON SENSE" .... I know ... we (they ... you) lost all common sense in these last 2 years.
bro you're yelling at a pbs science show for talking about science
@@platypiunited5509 This isn't the first strange comment he's left on this channel, not sure what his deal is 🤷♂️
Being a scientist, normally I do not post salty responses to YT vids but if ever there was a moment to remark that a video left a bad taste, this HAS to be it.
Because around 11:06 when the host calls out the unresolved "mystery receptor' so elusive amongst the 'taste community' I laughed so hard my salted coffee gushed through my nose.
I was thinking by that point,
If Na+ has a well-understood salt taste mechanism 1 ...
Then.... WHAT oh WHAT could salt taste mechanism 2 possibly BE???
Uh, just what else is in that there salt? Oh chloride you say? Right...
MAYBE just MAYBE could there be a chloride-related mechanism??
Turns out, the fifth result on the first page of Google Scholar for search terms "chloride ion receptor taste" right now is this research out of Tokyo confirmed the same, released earlier this year :
www.biorxiv.org/content/10.1101/2022.02.23.481615v1.full.pdf
It's not precisely a chloride channel as it is with sodium, but rather that chloride blocks taste receptors for sweet and umami that which provides a second major salt taste mechanism.
Somehow, sometimes the preposterously obvious is really quite elusive isn't it? After seeing George demonstrate on-screen that KCl tastes almost the same as NaCl, is it odd it didn't occur to anyone creating or consulting the show that there might be a Cl- mechanism? Perhaps a follow-on video could be warranted. And if so, maybe you can also explain how the 'taste community' ... missed this possibility?
Maybe we could have a chat with that study author, a certain Atsuko reachable at a_yama@okayama-u.ac.jp
And ask how the elusively obvious idea came to him??
I'll leave my fellow comments section readers here to judge whether salt really can make almost anything taste better, including this YT comment :-)
And to the video creators, good work keeping us engaged in the topic long enough to want to follow a hunch your vid brought up!
Fair points. Could be the mechanism. Could also be a combination of that with many other mechanisms working in concert, as is typical in human physiology.
Your comment reads a little supercilious though.
