The current situation is that when tasting substances with different tastes alone for a long time, the taste is perceived as different from the original taste.
(1) Water tastes sweet immediately after tasting sourness, bitterness, and strong saltiness.
(2) Immediately after eating dried squid, mandarin oranges taste bitter.
(3) Beer tastes sweet right after eating miracle fruit. This is thought to be due to the fact that miraculin (a substance that alters the sense of taste) in the miracle fruit not only changes sourness to sweetness, but also changes the function of taste receptors.
(4) After eating the white vine (Gymnema sylvestre), the sweetness disappears.
