Saccharin was invented by Russian Farid Berg. He is a researcher at the University of Baltimore and a chemist. One night it was Farid Berg's birthday. The couple invited some friends to have a feast. Not long after the dinner started, a friend suddenly said in surprise: "Oh, the crispy chicken nuggets are so sweet!" Another friend also said: "My sister-in-law actually fried sweet steak!"
Dinner After it was over, Faridberg sat on the sofa and thought about the strange sweetness. He took the plate that his friend had used and licked it, and it was sweet; he picked up the big plate that had been used and licked it, and it was also sweet. Finally, he took out the pencil from his pocket and licked it. It was still sweet! Suddenly, he figured out: "What kind of thing in the laboratory dyed the pencil sweet!"
Early the next morning, Faridelge rushed to the laboratory and inspected the used utensils one by one. . Faridberg discovered that the sweet smell on pencils was related to coal tar.
From then on, he concentrated on studying how to extract sweet substances from coal tar. Later, he extracted a sweetener from coal tar and named it "saccharin".
Experiments have proven that saccharin is 500 times sweeter than sugar. In 1879, Faridberg obtained the patent for the invention of saccharin. A year later, he established the world's first saccharin factory in Germany for commercial saccharin production. Saccharin has now become a food seasoning that ordinary people are accustomed to.
