Research-use notice
Independent study record
Each H2HUBB study page organizes source-linked research details for educational use. Interpretation should remain proportional to the study design, population, controls, and limitations.
H2HUBB TAKEAWAY
Compared with control pericarp, the pericarp of HW-treated litchi fruit exhibited higher levels of superoxide radical (O₂-·) scavenging activity, glutathione (GSH), monodehydroascorbate reductase (MDHAR), polyphenol oxidase (PPO) and total flavonoids during whole storage, higher levels of hydrogen peroxide (H₂O₂), catalase (CAT), glutathione disulfide (GSSG), ascorbate oxidase (AAO) and total phenols only on day 1. This source-grounded publication contributes evidence relevant to molecular hydrogen and is retained in a transparent general research category when a more specific study design is not supported by the indexed record. This plant postharvest study evaluated hydrogen water and is included as Related Mechanisms & Background Science. It provides no evidence of therapeutic effectiveness in humans or animals.
How Molecular Hydrogen Was Addressed
Litchi fruit were exposed to 0.7 PPM hydrogen water (HW) before storage at 25 ± 1 °C.
