Is water tasteless 1

Why is water tasteless?

Consumer water is not tasteless. Sources of flavor include (1) chemical and microbial content most influenced by geology and ecology; (2) chemicals added or removed during water treatment; and (3) inputs and reactions that occur during distribution and storage (Dietrich, 2006).

Two examples of ecology-related flavors are geosmin and 2-methylisoborneol, which are responsible for earthy and musty smells, respectively, caused by Cyanobacteria and actinomycetes are produced (Izaguirre et al. , 1982). People recognize these earthy and musty smells in concentrations of just a few ng / l. The ability to smell geosmin and 2-methylisoborneol is affected by other factors, such as the presence of chlorine which causes odors masked(Dietrich, 2006).

The ability of organisms to detect microorganisms such as cyanobacteria is not trivial, since cyanobacteria have toxic microcystins hepatotoxic and neurotoxic Produce properties that can cause disease and even death (blaha et al. , 2009) .

From an evolutionary point of view, I think it would be more important for survival to taste pollutants in the water than to mask these components by creating a taste for water that may make the detection of toxins less effective.

Adding to the water is not a tasteless point - in general, water you drink in cities tastes significantly different from water you drink in rural areas.


Food and drink that are very cold are characteristically less fragrant than anything that is room temperature or hot. There is definitely something to consider. You can also control the solutes in the water to get a desired taste. Reverse osmosis systems remove all solutes in water and add calcium, magnesium, etc. after the process. In my hometown, the water from the fountain in the lobby of the reverse osmosis plant was the best tasting I've personally had as it hadn't made it through the city's aqueducts (this adds some flavor).


@ DavidGrinberg You won't taste the water when you say that water from two sources tastes different. You actually try the solutes.

Then why are all other foods (fruit, meat, vegetables) full of flavor? Wouldn't it be better than, for example, having apples tasteless so we could taste rot? Or I could ask the reverse question: Wouldn't it be better for the human body to give water a good taste in order to make it at a nutritional price like most other natural good foods?


Since the thirst is quenched by a liquid and there are almost no liquids in nature that do not mainly consist of water, none of them tastes even slightly pleasant. Water doesn't have to taste good because water is all you have. But there are many, many solids out there, so certain must taste good. You can also detect water more easily by getting it wet than trying to develop a chemical sensor that detects water in water-laden slime.
