Michiyo Tsujimura was a prominent Japanese agricultural scientist and biochemist. She was born on 17th September 1888 in Okegawa, Japan. Her research was mainly focused on green tea components. She became the first Japanese woman to earn a doctoral degree in agriculture. She studied at Tokyo Prefecture Women’s Normal School. In 1909, she graduated from Tokyo Women’s Higher Normal School.

Michiyo Tsujimura and her achievements
Google gave special recognition to the tea scientist Michiyo Tsujimura on her 133rd birth anniversary with its doodle graphic. Her groundbreaking study helped her achieve a doctorate in agriculture. Being a woman scientist was not an easy career. Tsujimura began her career as a laboratory assistant at Hokkaido Imperial University without any wage. After some years, she joined the Tokyo Imperial University and Dr. Umetaro Suzuki, well-known for his remarkable discovery of vitamin B1. She started studying the biochemistry of green tea. They discovered that green tea is packed with significant amounts of vitamin C. It was the first ingredient to be caught under the microscope.
During the period of her study, Tsujimura discovered the reason which makes green tea bitter. She found that flavonoid catechin in green tea creates a bitter taste. She isolated the mixture in 1929. Then she extracted tannin in crystal from green tea. Her study paper on- ‘On the Chemical Components of Green Tea’ was published in 1931 which helped her become a doctor of agriculture from Tokyo Imperial University. She created a name for herself as an educator. In 1949, she joined as a professor at Ochanomizu University. From 1950 she became a professor at Tokyo Women’s Higher Normal School. Later, she became the Faculty of Home. Economics’ first dean. She received the Japan Prize for Agricultural Science in 1956.
