As a flavor enhancer, adding salt to traditionally sweet dishes is necessary to amplify the sweet notes. A pinch of salt is core to most baked dessert recipes. Even if it is not listed in the ingredients, sprinkling some sea salt flakes or smoked salt over holiday ginger bread cookies brings out the sweetness of the sugar and enhances the ginger flavor. Sourness is a taste that detects acidity. These taste buds detect hydrogen ions from organic acids found in foods.
The mouth puckering sensation is common in citric fruits such as lemons and oranges, as well as tamarind and some leafy greens. The sour taste can also be obtained from foods soured through fermentation such as sauerkraut and yogurt, or through the addition of vinegar. Many salad dressings feature vinegar as a key ingredient, which is a perfect way to add sour notes.
You could also try adding lemon or orange zest to vinegar or even cream based dressings. Or, simply zest the top of your salad to help drive this craveable flavor sensation.
Being able to sense it in our chow, therefore, would seem like a handy tool for survival. Mice seem to have it figured out, kind of. Recent research has revealed that the rodents' tongues have two taste receptors for calcium. One of those receptors has been found on the human tongue, though its role in directly tasting calcium is not yet settled, said Tordoff.
Calcium clearly has a taste, however, and counterintuitively most mice and humans don't like it. People have described it as sort of bitter and chalky — even at very low concentrations. Tordoff thinks our calcium taste might actually exist to avoid consuming too much of it. An over-sensitivity to calcium-rich foods such as spinach could help explain why four out of five Americans don't get enough calcium.
As for milk and other calcium-loaded dairy, the calcium in it binds to the fat, so we don't taste the mineral all that much, Tordoff noted. That calcium receptor might also have something to do with an unrelated sixth-taste candidate called kokumi , which translates as "mouthfulness" and "heartiness. Ajinomoto scientists published a paper in early suggesting that certain compounds, including the amino acid L-histidine, glutathione in yeast extract and protamine in fish sperm, or milt — which, yes, they do eat in Japan, and elsewhere — interact with our tongue's calcium receptors.
The result: an enhancement of flavors already in the mouth, or perhaps a certain richness. Braised, aged or slow-cooked foods supposedly contain greater levels of kokumi. If all that sounds a bit vague, it does to Western scientists also. Ajinomoto representatives have visited Tordoff's group "and given us foods they say are high in kokumi — but we have no idea what they're talking about," he said. Spicy-food lovers delight in that burn they feel on their tongues from peppers.
Some Asian cultures consider this sensation a basic taste, known in English as piquance from a French word. You can find umami in foods prepared Umami plays an extremely important role in the survival of each and every individual. This is particularly true during infancy.

None of these tastes are elicited by a single chemical. Also, there are thresholds for detection of taste that differ among chemicals that taste the same.
For example, sucrose, 1-propyl-2 aminonitrobenzene and lactose all taste sweet to humans, but the sweet taste is elicited by these chemicals at concentrations of roughly 10 mM, 2 uM and 30 mM respectively - a range of potency of roughly 15,fold.
Substances sensed as bitter typically have very low thresholds. It should be noted that these tastes are based on human sensations and some comparative physiologists caution that each animal probably lives in its own "taste world". For animals, it may be more appropriate to discuss tastes as being pleasant, unpleasant or indifferent.
Additionally, there are some clear differences among animals in what they can taste. Cats, for example, do not respond to sweets due to a deletion in the gene that encodes one of the sweet receptors.
Perception of taste also appears to be influenced by thermal stimulation of the tongue. In some people, warming the front of the tongue produces a clear sweet sensation, while cooling leads to a salty or sour sensation. A very large number of molecules elicit taste sensations through a rather small number of taste receptors.
