Gizmodo reported that researchers at the University of Copenhagen have come up with a “magnetic tongue” that could be used by food processors to “taste” the flavor of tomatoes during the canning process.
The scientists said they were able to determine the levels and types of sugars and amino acids in 18 tomato samples, which were also tested by professional human tasters. The researchers correlated the results of the machine with the descriptions of the human taste testers, and then they say they were able to create their mechanical tester to determine the bitterness, sweetness, sourness, saltiness, texture and density of the products.
