Effects of hydrogen water treatment on antioxidant system of litchi fruit during the pericarp browning.
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.

In a laboratory model, the data provide new insights into the postharvest quality reduction of Lanzhou lily scales mitigated by H₂ fumigation. The authors concluded that the results indicated the H₂ remarkably declined the color variation and browning degree in Lanzhou lily scales by suppressing the activity of phenylalanine ammonia-lyase (PAL), peroxidase (POD) and polyphenol oxidase (PPO). These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.
