On that day, luck laid waiting for employee of an American laboratory Russian emigrant Constantine Fahlberg. He sat to dinner without having washed his hands, and bread tasted sweet to him. His family members were surprised, while Fahlberg realized that the sweet taste comes from his hands soiled with compounds of ortho-sulphobenzoic acid. This was how saccharin – artificial sweetener which is by hundreds of times sweeter than sugar – was discovered. The world war secured gigantic demand for it. However, the substance is not forgotten today either. It is used to sweeten toothpaste.
