The Global Matcha Research Library
641 papers, trials, theses and preprints that study matcha, gathered from PubMed, OpenAlex and Europe PMC, tagged by study type and topic, and linked back to every source. We keep abstracts and citations; the full text stays with its publisher.
Tip: use "quotes" for an exact phrase, OR between alternatives, and a minus to leave a word out, for example fluoride OR pesticide. Related words are matched too, so “EGCG” also finds “epigallocatechin.”

Kenji Haraguchi — Journal of Japan Association on Odor Environment抹茶は中国を起源とし，日本には約800年以上前に伝わった．飲料としてだけでなく，文化としての茶道が確立するなど，日本で独自の発展を遂げた．生産方法においても改良が積み重ねられ，被覆栽培やてん茶機による製造技術が完成した．抹茶の香りの特徴は，被覆栽培によって茶葉中のアミノ酸やカロテノイド含量が高まり，これらが前駆体となって覆い香のジメチルスルフィドやヨノン系の香気成分が生成することである．抹茶は馥郁たる香味を有し，近年は食品加工用素材として需要が国内外で高まってきている．

How this library is built
Every record comes from three open scholarly indexes — PubMed, OpenAlex and Europe PMC — searched for the word “matcha.” Records are merged by DOI and PubMed ID so each study appears once. A paper is kept only if matcha appears in its title, abstract, author keywords or subject terms and the text is about tea or food, which filters out the surname Matcha, software called Matcha, and the Scandinavian verb “matcha” (to match).
Study type and topic tags are assigned automatically from each paper's own title, abstract and subject terms using fixed keyword rules — no guesses, and papers without an abstract are marked as unclassified. Automatic tagging is imperfect, so treat tags as a way to narrow a search, not as a verdict on a paper's quality. A study being listed here is not an endorsement of its findings.
Coverage: this is every indexed paper that names matcha, not every study of green tea or its compounds (those are far more numerous). Papers that mention matcha only in passing are hidden by default. Work that never uses the word “matcha,” and publications outside these indexes, are not included. The library was last rebuilt October 20, 2026.
