The compound in plants that causes them to be green in color is chlorophyll. While chlorophyll is present in the stevia plant, it does not contribute to the sweet taste you get from the stevia leaf. The chlorophyll actually has a bitter taste. The sweetness in the stevia leaf is contributed by compounds called steviol glycosides. These glycoside molecules are much smaller than the molecules that make up chlorophyll. Since the chlorophyll does not contribute to the sweetness of the stevia and causes a bitter taste, we use simple micron filtration, not chemicals, to remove the chlorophyll (green color), leaving the finished product with a slight amber color. Micron filtration is similar to reverse osmosis which is used in the purification of water. Our process is a 100% natural from start to finish.
