Microgreen kangkong is a young vegetable packed with more beneficial compounds than regular mature kangkong. Researchers found that wrapping these beneficial compounds in a protective coating made from maltodextrin and gum Arabic using freeze-drying technology preserves their health benefits. The best protective coating ratio was 20% maltodextrin and 80% gum Arabic, which kept more of the beneficial compounds intact and created a powder that could be used in functional foods and health supplements.
