Human taste testers now face competition and their jobs may be at risk. No, we are not talking about outsourcing to India or China, instead there is a possibility of machines taking over.
The issue with tasting is that the taste depends not only on the combination of ingredients in the food, but also on the taster's emotional state. We know from our own experiences when certain foods taste better under certain circumstances. Trained taste testers eliminate some of the variation, but they are still humans. This is where electronic sensing technologies come in.
Researchers used nuclear magnetic resonance spectroscopy (NMR) to test its abilities as "a magnetic tongue." Eighteen canned tomatoes were analysed. It was found that the instrument could estimate most of the tastes assessed by the human taste testers. But the instrument went even further. By determining the chemical composition, it showed which compound is related to which sensory descriptor. The researchers said that the "magnetic tongue" has good potential as a rapid, sensitive and relatively inexpensive approach for food processing companies to use.
It sounds a bit unusual that we will rely on machines to taste foods that humans will eat. However in a way it makes sense since the human testers can be a bit unreliable. If we were to taste food that only we would eat then there is little need for machines. However if the food is being tasted for the general public then I suppose having unbiased opinion becomes more important.
