Astringent (taste)

From Wikipedia, the free encyclopedia
Not to be confused with Astringent.

Astringent is a taste that puckers the mouth, numbs the tongue, and constricts the throat. This taste is caused by astringents such as tannins.[1][2] Unlike other tastes astringency is not perceived via taste receptors but is a tactile sensation caused by the aggregation of saliva proteins.[3][4]

The astringent taste is in unripened bananas, unripe persimmons and cashew fruits; and acorns[5] dominantly, which prevents them from being eaten.

Squirrels, wild boars, and insects can eat astringent food as their tongues are able to handle the taste.[5]

In Ayurveda, astringent is the sixth taste (after sweet, sour, salty, pungent, bitter) represented by "air and earth".[6][7]

Smoking may also cause astringent taste.[8]
