20 Oct 2017 --- For the first time scientists have completed the sequencing of the stevia plant genome unveiling major breakthroughs in research. Scientists from producer and innovator of stevia sweeteners for the global beverage and food industry, PureCircle, have found a way to map the genetic makeup of the stevia plant, in what they claim is a pioneering move. The mapping will provide an in-depth understanding of how the calorie-free sugar substitute derives its characteristic sweetness.
