By | September 17, 2021

Google Doogle is celebrating  the life and legacy of Michiyo Tsujimura, a japanese biochemist who was instrumental in the discovery of why why green tea tastes so bitter when steeped for too long and other ground breaking researches conducted by her.

Today’s Google doodle commemorates the 133rd birthday of Dr Michiyo Tsujimura, whose research on green tea provided invaluable information about its nutritional and chemical profile.
Her work revealed green tea’s high vitamin c content and the isolation of catechin and tannin, the bitter compounds of tea.

Tsujimura, a Japanese chemist best known for her in-depth research into green tea, is the subject of the most recent Google Doodle. Green tea was discovered to be a natural source of vitamin C by Michiyo Tsujimura and her colleague Seitaro Miura. Their work resulted in a significant increase in the amount of green tea exported to North America.

She was born in Japan’s province of Okegawa, she studied at Hokkaido Imperial University where she majored on science related subjects. She started her early career teaching science in the early 1920’s.

A few years later, Tsujimura transferred to Tokyo Imperial University and began researching the biochemistry of green tea alongside Dr Umetaro Suzuki, famed for his discovery of vitamin B1. Their joint research revealed that green tea contained significant amounts of vitamin C-the first of many yet unknown molecular compounds in green tea that awaited under the microscope. In 1929, she isolated catechin – a bitter ingredient of tea. NDTV reported.
