Pepsico not too long ago, and maybe still now, had a process in which they used aborted fetal kidney cells to somehow evaluate the flavorings in their soft drinks. How that is supposed to beat out the old fashioned taste test, I do not know.
That's because Pepsi products taste so crappy, they had to find something that had no choice BUT to stay and react to the foul stimuli. Adult human taste testers kept quitting.
