When sourcing coconut water powder, the primary focus should be on the drying process and solubility. Spray-dried powder is common and cost-effective, while freeze-dried powder better preserves the natural nutrients and flavor profile. Ensure the particle size (mesh) is fine enough for instant dissolution in cold water. Additionally, check the electrolyte content, specifically levels of Potassium, Magnesium, and Sodium, as these are the primary functional drivers for the beverage and sports nutrition industries.
