水素水処理が発芽黒大麦の栄養成分および抗酸化特性に与える影響
This study examined the effects of hydrogen-rich water (HRW, 2 ppm) on sprouted black barley (Hordeum distichum L.) during germination processing. HRW treatment significantly elevated both germination rate and growth rate compared with ultra-pure water controls (P < 0.05). Chemical composition analysis revealed that HRW altered phytochemical distribution, including changes in guanosine ionic strength, and increased concentrations of free vanillic acid, coumaric acid, sinapic acid, conjugated sinapic acid, calcium, and iron. Hydroxyl radical scavenging capacity was also enhanced. Conversely, contents of protein, fat, starch, and dietary fiber were reduced relative to the ultra-pure water group. These findings suggest that HRW application during grain sprouting can improve germination efficiency and elevate bioactive phytochemical levels in the resulting product.
HRW is proposed to modify phytochemical distribution during germination, elevating phenolic acid concentrations (vanillic, coumaric, and sinapic acids) and mineral levels (Ca, Fe), thereby enhancing hydroxyl radical scavenging capacity in sprouted black barley.
Hydrogen-rich water is a low-risk delivery route, but the achievable systemic hydrogen dose is bounded. For clinical applications, inhalation is the most efficient route; inhalation, however, carries explosion risk, and concentration matters (empirical LFL of 10% applies to inhalation environments; high-concentration devices are documented in the Consumer Affairs Agency accident database and are not recommended).
