This position would mark the beginning of her groundbreaking work in green tea research.
Career Path and Achievements
Tsujimura’s career transitioned from teaching to research when she joined the food nutritional laboratory of the university’s agricultural chemistry department at Hokkaido Imperial University. As a researcher, she focused on the “Nutrition of Silkworm”. Her work eventually led her to become the first female professor emeritus in the Agricultural Chemistry field.
Her groundbreaking research culminated in prestigious accolades, including the Japan Prize for Agricultural Science in 1956 and the Order of the Precious Crown of the Fourth Class in 1968. These awards recognized her significant contributions to green tea research and her trailblazing role as a female scientist in a male-dominated field.
The Science Behind Green Tea: Tsujimura’s Discoveries
Michiyo Tsujimura’s research on green tea components led to some groundbreaking discoveries, including the identification of vitamin C, flavonoid catechin, and tannin in green tea. Her work not only expanded our understanding of green tea’s chemical makeup but also shed light on its numerous health benefits.
These findings transformed the green tea industry, instigating additional research into the prospective health benefits of green tea consumption. With each sip of green tea, we can appreciate the scientific advancements made possible by Tsujimura’s pioneering work.
Vitamin C in Green Tea
Collaborating with Seitaro Miura, Tsujimura conducted research that led to the detection of high levels of vitamin C in green tea. This groundbreaking discovery not only reinforced the nutritional value of green tea but also played a crucial role in boosting green tea exports to North America.
Tsujimura’s discovery was enthusiastically accepted by the scientific community, as it confirmed the substantial presence of vitamin C in green tea. This finding bolstered consumer interest in green tea an
d spurred further research on its health benefits, solidifying green tea’s reputation as a health-promoting beverage.
Flavonoid Catechin and Tannin
In 1929, Tsujimura isolated flavonoid catechin in green tea, and in 1930, she was able to extract it in crystal form. This discovery marked a significant milestone in green tea research, as flavonoid catechins are known for their antioxidant and anti-inflammatory properties, which contribute to the health benefits of green tea consumption.
Her research on tannin in green tea uncovered its contribution to the beverage’s unique astringent and slightly bitter taste. Tannins are a type of polyphenol known as catechins, which are recognized for their astringency. These findings further enriched our understanding of green tea’s unique flavor profile and health-promoting properties.
