To preserve coconut drink and significantly increase its shelf life, add food-grade hydrogen peroxide and keep it chilled.
Here's a breakdown of the process:
- Adding Hydrogen Peroxide: Incorporate food-grade hydrogen peroxide (50% vol) at a ratio of 1 mL per liter of filtered coconut water.
- Chilling: After adding the hydrogen peroxide, chilling the solution further enhances its shelf life.
This method can extend the shelf life to approximately 24 hours.
