Recent Knowledge on the Applications of Molecular Hydrogen in Plant Physiology, Crop Production, and Food Processing

Molecular hydrogen (Hydrogen gas, H2) has recently attracted the attention of researchers across multiple fields due to its several beneficial biological activities. The reducing capacity, antioxidant activity, and zero residual and eco-friendly properties make hydrogen gas a multi-purpose candidate for various crop production and food processing. Recent studies have shown that hydrogen can modify the physiology of plants where many physiological events such as seed germination, plant growth, and development have been changed due to the presence of hydrogen. Other studies have shown the ability of hydrogen to induce anti-stress responses in various plants. Similarly, in post-harvest crops, hydrogen has exhibited different beneficial properties such as the extension of the shelf life and the protection of the quality attributes of produce. In food processing, recent studies have revealed the ability of hydrogen to protect the nutritional and sensory properties of the product during the storage period or the preparation of the final product.

This Research Topic aims to collect lastest knowledge and studies relating to the use of hydrogen in plant, crop production, and food processing. This collection aims to compile knowledge of the different mechanisms and potential roles of hydrogen in the food production chain. Due to the limited research on hydrogen application in the crop and food field, we believe that a bespoke collection of the latest hydrogen-related works will be helpful for both researchers and technologists.

This Research Topic will cover various aspects of hydrogen applications along with plant physiology, and crop and food production:

• The mechanisms involved in the physiological responses of plants to hydrogen application
• Effect of hydrogen on the biotic and abiotic stresses in plants
• Effect of hydrogen on the quality of vase life of the flower
• Effect of hydrogen on the post-harvest quality of crop
• Use of hydrogen for the increase of crop production
• Use of hydrogen for the increase of nutrients in crops
• Hydrogen application for sustainable handling and storage of crop materials
• Future of hydrogen for global food security
• The effect of hydrogen on plant and food-related enzymes
• The effect of hydrogen on plant and food-related microorganisms
• Effect of hydrogen on the levels of foodborne pathogens in fruits and vegetables
• Use of hydrogen in food and beverage packaging
• Use of hydrogen in animal health and production
• Effect of hydrogen on fish physiology

All the types of manuscripts are welcomed such as reviews, full research articles, and short communication.
