It suggests the tongue might detect ammonium chloride as a basic taste, which could lead to an expansion of current thinking that there are five tastes (sweet, sour, bitter, salty and umami or savory). (foodingredientsfirst.com)
A team of scientists led by neuroscientist Emily Liman from the University of Southern California Dornsife, US, has uncovered that the tongue can sense ammonium chloride, a compound with a chemical tang, through the same protein receptor responsible for detecting sour tastes. (foodingredientsfirst.com)
While ammonium chloride might not be a staple in every kitchen, it holds a particular place in making salted licorice candies in North Europe. (foodingredientsfirst.com)
Despite this widespread use of ammonium chloride in some regional sweets, the enigma of how the tongue perceives ammonium chloride remained largely unsolved until Liman's team ventured into the exploration. (foodingredientsfirst.com)
Ammonium chloride is a common ingredient in making salted licorice candies in North Europe ( Image credit: Licorice International ). (foodingredientsfirst.com)
As Liman's research establishes, OTOP1, a protein receptor in the tongue, is sensitive to ammonium chloride, even more so than to acids, highlighting a discovery about our taste mechanics. (foodingredientsfirst.com)
When ammonium chloride is encountered, it releases a small amount of ammonia within cells, subsequently altering their pH levels and initiating a proton influx through the OTOP1 channel, the study found. (foodingredientsfirst.com)
Courtney Wilson, a postdoctoral research fellow from Liman's research team, also tells us: "We'll need more research into both how humans respond to ammonium chloride in foods and how the taste of ammonium chloride interacts with other taste stimuli to get the full picture of how ammonium chloride impacts flavor. (foodingredientsfirst.com)
Our study is in laboratory mice, who don't tend to like the flavor of ammonium chloride. (foodingredientsfirst.com)
The mice in our study tend to avoid ammonium chloride (unless they lack OTOP1 and Type II taste cells), but some humans enjoy ammonium chloride in salty licorice," Wilson explains. (foodingredientsfirst.com)
It might be tempting to christen this sensation elicited by ammonium chloride as a new, distinct taste modality - potentially a sixth taste. (foodingredientsfirst.com)
It's been known for quite a while in the taste field that ammonium chloride generates a sizable taste nerve response in mice and other mammals and that mice avoid ammonium chloride solutions as the concentration increases in behavioral experiments. (foodingredientsfirst.com)
We sought to identify the mechanism(s) behind this response and found that OTOP1 is sensitive to ammonium chloride in addition to sour/acidic stimuli. (foodingredientsfirst.com)
As evidenced by our behavioral experiments, mice use OTOP1 as well as a population of Type II cells (we suspect a population of cells that respond to bitter stimuli) to detect and avoid ammonium chloride. (foodingredientsfirst.com)
So, in mice, the taste bud is required to detect and avoid ammonium chloride solutions. (foodingredientsfirst.com)
But whether the sensation elicited by ammonium chloride constitutes its own separate taste modality in mice or in any other animals remains to be seen," she elaborates. (foodingredientsfirst.com)
