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.”

Influence of Continuous Ingestion of Matcha Latte on Stress: A Preliminary Study

Manami Monobe, Sachiko Nomura, Kaori Ema — Chagyo Kenkyu Hokoku (Tea Research Journal)

カフェイン+EGCG/テアニン+アルギニンのモル比が2未満の高級抹茶を継続摂取するとストレッサーによる侵襲を受けにくいことが既に報告されている。一方,カフェイン+EGCG/テアニン+アルギニンのモル比が2以上の抹茶ではストレッサーによる侵襲を受けてしまうことが本研究でも明らかになった。しかし本研究では,上記モル比が2以上の抹茶ラテを飲用していた場合,不安状態における交感神経系を介したストレス防御反応の低下を抑える可能性があることが示された。

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.
