Product Description
Purple sweet tomato extract 

Product Information: 

Purple sweet potato powder is a purely natural ingredient extracted from purple sweet potato that is planted locally, and is rich in anthocyanin and minerals.

Its main composition is anthocyanins, therefore, it has anti-oxidation, anti-aging and anti-fatigue effect, and can enhance body immunity for long term consumption. Its color won't fade under light; also it can endure high temperatures in acidic media, but changes with pH condition. When it used in acidic condition, the color is ranging from red to purple-red and is unstable when PH is above 6. When it is used in alkaline condition, the color becomes to purple-blue because it's easy coordination with metal ions.
