An empirical exploration of the capacity of choline chloride/lactic acid eutectics to extract and stabilize natural polyhydroxy compounds.

Summary: Scientists have found a much better way to pull out healthy, natural colors and chemicals from plants. They mixed two safe ingredients—choline chloride and lactic acid—to make a special liquid. When they added sound waves (ultrasound) to this liquid, it worked like magic! It pulled out up to 300% more plant chemicals than older methods. Even better, this special liquid acts like a shield. It keeps the natural colors fresh and stable for nearly a month, up to four times longer than regular liquids. This is great news for making natural medicines and food dyes!
