Hydrogen Water Preservation Duration Based on Storage Conditions
- Open Container at Room Temperature:
- Hydrogen water’s negative potential can be maintained for 10–15 minutes in an open container at room temperature.
- Best consumed within 24 hours.
- Sealed Plastic or Glass Container at Room Temperature:
- Under sealed conditions, hydrogen water can be preserved for 24–72 hours, depending on the manufacturing technology and equipment.
- Some companies claim their hydrogen water can last up to a week.
- Lightproof, Sealed Aluminum Packaging:
- When stored in lightproof and sealed conditions using food-grade aluminum, hydrogen water can last for up to 180 days without significant changes in its properties.
Storage Methods for Hydrogen Water
- Refrigerated and Sealed:
- Store hydrogen water in a refrigerator at 2–8°C to slow down hydrogen escape and prolong its shelf life.
- A sealed environment minimizes exposure to air, further reducing hydrogen loss.
- Pressure-Retaining Containers:
- Use specialized pressurized bottles for storing hydrogen water.
- These containers help maintain internal pressure, increasing hydrogen’s solubility in water and reducing escape.
- Canned Hydrogen Water:
- Food-grade metal cans with good barrier properties effectively prevent hydrogen leakage and block external oxygen.
- Metal cans also shield hydrogen water from light, reducing photolytic reactions and maintaining the stability and activity of dissolved hydrogen.
Latest Hydrogen Water Bag Storage Technologies
- Aluminum Foil Composite Hydrogen Water Bags:
- The surface features aluminum foil, which provides excellent barrier properties.
- Blocks hydrogen escape and prevents the intrusion of oxygen, moisture, and other external factors, thereby extending storage time.
- Pressurized Hydrogen Water Bags:
- Equipped with a pressure control system that stabilizes internal pressure.
- Enhances hydrogen solubility in water and minimizes escape.
- Multi-Layer Composite Hydrogen Water Bags:
- Inner Layer: Made of food-grade plastic, ensuring water resistance and compatibility with hydrogen water.
- Middle Layer: Acts as a barrier, often made from materials like ethylene-vinyl alcohol copolymer (EVOH), effectively blocking hydrogen permeation.
- Outer Layer: Provides strength and durability to the bag, protecting against physical damage.
These advanced storage methods significantly improve the retention of hydrogen in hydrogen water, ensuring its quality and efficacy for extended periods.
