You missed stainless steel. After discarding random new experimental alloys into a rusting pile of them one remained shiny so stood out. A casual lick test proved it to have no metalic flavour like all the other alloys did.... which meant it didn't tarnish and remains the perfect thing for making cutlery! Sometimes it is best to be tasteless.

Because licking the science is actually pretty handy sometimes. Licking the lab rocks was expected in my college geology class. Easiest way to identify the salt crystal. Though safety is important. We often used a very diluted hydrochloric acid on the same rocks. It is also salty. The tip of my tongue was numb the rest of the day. Did that stop me from tasting the science? Nope, but I was much better about washing them before hand.

Archaeologists also do the 'lick test'. I was on an excavation in my second year of university and a fellow student thought they'd found a piece of animal bone. We all crowded around because it was the first exciting find, and to everyone's horror... You guessed it, our professor licked it and said "Yep, it's bone", with a smile. I've seen her tasting soil too, because we need to find the exact texture and composition of the soil we find an artefact in, and tasting it is a quick and easy way to figure out the texture (or so I'm told).

Syster Yster en.wikipedia.org/wiki/Aspartame?wprov=sfti1 It says clearly that aspertane doesn’t cause cancer, and is recognized as safe for consumption in more that 90 countries. All artificial sweeteners, preservatives, and other additives have to go through lots of testing to insure that they are safe. People think MSG is bad for you, when it is completely safe and adds a ton of flavour to many dishes. It’s like the salt and pepper of Asia.

The purpose of the pancreas was discovered by a researcher who removed the pancreas from dogs....and noticed they died. He also noticed that ants were congregating at yellow wet spots in the dog cages, so he tasted it (urine) and it was sweet, like sugar: excess sugar: insulin production. Also, ancient doctors would taste urine to diagnose their patients.

Missed one: “Sucralose was discovered in 1976 by scientists from Tate & Lyle, working with researchers Leslie Hough and Shashikant Phadnis at Queen Elizabeth College (now part of King's College London). While researching ways to use sucrose and its synthetic derivatives for industrial use, Phadnis was told to "test" a chlorinated sugar compound. Phadnis thought Hough asked him to "taste" it, so he did. He found the compound to be exceptionally sweet.”

Yeah, "debatable" is an understatement. Sodium cyclamate has been in use in Europe as the preferred artificial sweetener since the 1960's with no recordable increase in cancer rates per capita that can be even circumstantially linked. And the lab that concluded it causes bladder cancer? Paid for by a sugar refinery.
