It is said that plain water is odorless, colorless and tasteless, however, this latter feature can not be entirely true.
Scientific research has found that some species react to the taste of water .
In 2015 a group of scientists from the University of California, USA, reported queciertos insects have a gene that makes proteins to taste the water in the cellsof taste. This research was led by biologist Peter Cameron and his studies focused on the fruit fly. The protein produced by these insects named PPK28.
Furthermore, some living things have aquaporins, which serve to convey and absorb water through cell membranes. These aquaporins could be key to the vital fluid stimulates the cells of taste in certain species.
In addition, Sidney Simon physiologist at Duke University, USA, found cells for water in the gustatory cortex of rats. However, much of the scientific world states that these cells are not found in most mammals, particularly in humans.
Even between the 1960s and 1970s, it was shown systematically that the taste of water in humans, depends on what has been ingested before. This research was conducted by psychologist Linda Bartoshuk, who published a series of articles on the aftertaste of water. According to the researcher at the University of Florida, water has flavor , but only after having tried something else.
However, plain water can have an effect on the taste buds of people by the presence of some minerals. For example, chlorides cause a taste salty, bitter one magnesium and aluminum earthy one.
Chemicals, algae , bacteria, decomposition of plant and inorganic waste, can also modify the taste of the water. In this case the quality of drinking water has to be subject to review measures to prevent disease.
Without doubt, water is vital for all living beings regardless of their taste . Therefore, their care and conservation are key to health, hygiene, food and a long list of daily activities.
