水素ガスによる園芸作物の収穫後鮮度保持：生化学的メカニズムと応用展望
This review consolidates current findings on hydrogen gas (H₂) as a gaseous signaling molecule involved in postharvest senescence of horticultural products. Evidence indicates that H₂ modulates multiple biochemical pathways, including enhancement of antioxidant defense systems, activation of cell wall metabolism, stimulation of energy metabolism, suppression of ethylene biosynthesis, and regulation of microbial communities. Interactions between H₂ and other signaling molecules are examined, along with the biological safety profile of H₂ in postharvest contexts. The review also outlines downstream molecular targets relevant to H₂ biology and discusses the scientific and practical implications of applying H₂ for extending the shelf life of perishable horticultural commodities.
H₂ delays postharvest senescence by upregulating antioxidant systems, activating cell wall and energy metabolism, inhibiting ethylene biosynthesis, and modulating bacterial communities on horticultural products.
The delivery route is not clearly identifiable from this paper. For hydrogen intake, inhalation is the most efficient route; inhalation, however, carries explosion risk (empirical LFL of 10%; high-concentration devices are not recommended).
