Abstract
Featured Application: It is proposed here that the use of molecular hydrogen should be considered more widely for the treatment of post-harvest fruits, vegetables and flowers. This can be applied as a gas, or in solution, and costs associated with its use expected to fall as hydrogen is adopted by other industries. Molecular hydrogen (H2) has been found to have significant effects in a range of organisms, from plants to humans. In the biomedical arena it has been found to have positive effects for neurodegenerative disease and even for treatment of COVID-19. In plants H2 has been found to improve seed germination, foliar growth, and crops: effects being most pronounced under stress conditions. It has also been found that treatment with H2 can improve the postharvest preservation of fruits, vegetables and flowers. Therefore, H2-based treatments may be useful for the storage and transport of food products. H2 can be delivered in a range of manners, from the use of the gas to creating H2-enriched solutions, such as hydrogen-rich water (HRW) or hydrogen nanobubble water (HNW). The exact action of H2 at a biochemical level has yet to be established. Despite this, H2 appears to be safe. Treatments of food with H2 would leave no harmful residues, and H2 itself is safe to use, as exemplified by its biomedical use. With H2 production and transport being developed for other industries, H2 is likely to become cheaper and its use for postharvest maintenance of food may be beneficial to explore further.
