TSUJIMURA MIKHIYO, A JAPAN GREEN TEA RECALKER, CELEBRATES AGEMENT TODLE’S 133RD BIRTHDAY.
Today is the 133rd anniversary of the Japanese professor and biochoke artist Michiyo Tsujimura.
You don’t have to soak it too long, otherwise it tastes harsh if you like green tea. Well, for that information, you have Tsujimura to thank.
Tsujimura was born in 1888 and was the first woman in Japan to earn a PhD in farming. She was taught by another renowned scientist, Kono Yasui, who was the first Japanese woman to graduate in science.
She was not easily recognized as a female scientist during her career.
But she first became aware of the fact that green tea contained vitamin C in 1924, together with her colleague Seitaro Miura. Their paper “Vitamin C in Green Tea” resulted in increased exports of green tea to North America. They released an article.
She continued her study of green tea and extracted catechin in 1929, which is a bitter element in tea.
The year after, she isolated tannin, a chemical that is much more bitter.
These two discoveries formed the basis of her thesis on “Green Tea Chemical Components.”
In 1934, gallocatechin was isolated from green tea, and in 1935, a patent on her plant extraction technique was issued.
and In 1950, she became a teacher of history when she first became a dean of Tokyo’s Faculty of Home Economics. In 1955, she retired but still taught part-time teaching.
On 1 June 1969 at the age of eighty, Tsujimura died in Toyohashi. Her birthplace in Okegawa City is home to a stone monument in her honor.
