This works on "tastes" at the lowest level definition of "taste", in other words tongue sensations. But what we think of as "taste" is actually a combination of this and of smell or aroma.

Smell is much more complex and relies on detection of the shape of the particles by the olfactory receptors (see: http://cst.ufl.edu/taste-vs-flavor-whats-the-difference.html).

It could be possible to simulate different aromas with a fairly small number of scent molecules, and there has been some work in that direction (see: https://www.researchgate.net/publication/227512326_Aroma_sim...), but no successful commercial product has ever been launched (that I'm aware of) based on this technologly.

So while interesting, this 'taste synthesizer' and anything like it is not going to enable anyone to taste anything that really tastes like a food.
