Scientists have developed magnetic tongue to taste the taste of food

- Nov 21, 2017 -

According to S & T Daily, a new addition to the family of electronic sensory devices, the "electronic nose" for odor detection has a new companion "magnetic tongue" to replace human and animal taste perception. It is reported that many research institutes such as Aarhus University in Denmark and University of Copenhagen have jointly developed a method of "tasting" food taste, sweetness, bitterness and other indicators of taste more broadly and objectively than human tongue judgments, In the future is expected in the food processing as a sensitive and rapid detection tool. Related papers published in the Journal of the American Chemical Society "Agriculture and Food Chemical" on. Using NMR spectrometers as "magnetic tongues"(ndfeb magnets), the researchers tested 18 applications of canned tomatoes bought from the market to test their ability to sense taste.

They found that the instrument not only can determine the taste, such as bitterness, sweetness, sourness, saltyness, etc., perceived by most brain functional areas of the brain, but also beyond this range, and can detect the taste of the metal, the red level, Tomato density and so on. The instrument also detects chemical components of foods that are associated with taste characteristics through a metabolic approach. The researchers pointed out that this "magnetic tongue" in the future as food processing, as a fast, sensitive and relatively inexpensive detection tools. "China Quality News"
