In the eighties and nineties, kumiko organized international symposiums on umami taste. She believed that they couldn't fully debate whether mami was a taste if they didn't have the personal experience and vocabulary to talk about it.

He thought gludamat could be a taste signal for proteins, just like sweetness or salt. And in garry mind's mind there is an evolutionary explanation as to why people would feel this way.
